Top ten brands of waterproof coating

What are the mistakes in the use of waterproof coating? Waterproof coating is an essential material in home decoration, but many friends may buy inferior products because of their inexperience, which has a great impact on people's lives. But it may also cause many problems due to its improper operation. What are the mistakes in the use of waterproof coating? Mistakes in the use of waterproof coating 1. Although instructions for use are attached to the package of waterproof coating when the coating is purchased unevenly, in the actual construction process, the construction personnel perfunctorily stirred or directly mixed it manually with several sticks, which greatly reduced the performance of the cured film because of the performance of waterproof coating and liquid The mixing uniformity of the powder has a great relationship. 2. The package description of the product with too much water will suggest that the paint can be diluted by adding more water than the specified amount of water during the first coating construction, which is conducive to improving the permeability of the paint to the base course and improving the adhesion to the base course. However, due to lack of professional knowledge, many construction personnel will add water at will when using, which is counterproductive and will seriously damage the formula proportion of waterproof coating and affect its film performance. 3. The construction of waterproof coating for over dry or over wet base course requires high temperature and humidity. The suitable temperature is 5 ℃~35 ℃, and the humidity is 50%~70%. It does not mean that construction can be carried out under any humid climatic environment or very high moisture content of the base course. Too high moisture content of the base course and too humid climatic conditions are detrimental to the curing and film forming of polymer emulsion, and will reduce the elongation of the film. At the same time, the cement in the waterproof coating is solidified by water. Too dry base course and climatic conditions are unfavorable to cement solidification, so during construction in hot and dry seasons, the base course shall be sprayed with a little water before construction.

Waterborne paint VS oil-based paint? The comparison between water-based coatings and oil-based coatings should be based on the products of the same grade. Many people are not particularly clear about water-based coatings and oil-based coatings. What are the differences between water-based coatings and oil-based coatings? Waterborne coatings VS oil-based coatings Waterborne coatings have three types: one is water-based wood coatings with acrylic acid as the main component; The second is the composition of acrylic acid and polyurethane; Third, 100% polyurethane waterborne coatings, whose abrasion resistance is even several times that of oil-based coatings, are the advanced products in waterborne coatings. 1： Environmental protection From the perspective of environmental protection, water-based coatings have natural advantages over oil-based coatings (solvent based wood coatings). Theoretically, the lower the VOC content, the higher the environmental protection. However, the lower the VOC content has an impact on the abrasion resistance, hardness and scratch resistance of the oily coating. The above indicators have always been the technical problems of water-based coatings that need to be overcome. How to achieve both environmental protection and high quality is the focus of technical research of major coating manufacturers. 2： The technical requirements of cost-effective waterborne coatings on drying time, hardness, fullness and other properties are relatively high, the manufacturing process is relatively complex, and large-scale production equipment is required to produce products with relatively stable performance, and the production cost is relatively high. This is also the reason why the price of water-based coatings of the same grade is much higher than that of oil-based coatings. 3： Abrasion resistant water-based wood coatings are far inferior to oil-based wood coatings in terms of hardness, fullness, aging resistance and other decorative effects. Consumers with high requirements for home environment may even redecorate after three to five years. Because the abrasion resistance of general water-based coatings is not high, most consumers choose to use water-based coatings only on the wall, while oil-based coatings are used for parts that are often scrubbed, such as doors, windows and furniture. No matter it is water-based paint or oil-based paint, it should not rely too much on a certain kind of paint for home decoration. It should be a combination of the two to achieve the best painting effect. Therefore, we must specifically understand the difference between water-based paint and oil-based paint before painting.

Today's modern cities are no longer cement forests, but connect cities with nature and build green ecological cities. The sponge city is the product of the new era. As people expect, open and flat roads, neat and beautiful green belts, clean water and green wetland landscape, cool air full of vitality, beautiful ecological environment, harmonious blend of human and nature, the city exudes a different kind of charming charm - this is the life scene under the "sponge city". So, what is a "sponge city"? As the name implies, a sponge city means that a city can absorb, store, infiltrate and purify water like a sponge when it rains, and release and use the stored water when necessary, so as to realize the free migration of rainwater in the city. Since China launched the "sponge city" pilot project in 2015, the first batch of pilot projects have achieved certain results. However, there are still some unsatisfactory places that make people sigh. What is the problem? As a high-quality sponge city supplier, Shanghai Huwang Technology has told us that the key to building a green sponge city is not how many green belts are built on the road, but exactly where we can't see them. The so-called "If you want to do a good job, you must first sharpen your tools". To build a real sponge city, you must start with the most basic waterproof materials. In short, it is necessary to have a good waterproof board. In the practice of engineering projects, the advantages of polymer protection and drainage profiled sheet of Huwang Technology are also very obvious. The concave convex hollow vertical bar structure on the waterproof and drainage board can quickly and effectively export rainwater, greatly reduce or even eliminate the hydrostatic pressure of the waterproof layer, and finally achieve the effect of active waterproof. At the same time, polyethylene, as the main material, has a good waterproof property. Through reliable connection, Huwang Technology maximizes its role. According to the laboratory data, the waterproof and drainage board made of this material can effectively reduce the indoor noise, and can also play a very good role in ventilation and moisture-proof. More importantly, waterproof and drainage boards can effectively protect structures and waterproof layers, and resist various acids and alkalis in the soil and root thorns of plants. Only with excellent products and technologies can we truly solve the problem of difficult drainage for the city and build a green sponge city.

With the improvement of living standards, people have more and more strict requirements for home decoration. Home decoration is a big event for us. The main thing is to choose good materials. Roof insulation is one of the common ways of home decoration. So today, I will tell you about simple roof insulation methods to add beauty to your new house! Only when the decoration is good can we live comfortably. 1、 What can we do to make the roof insulated? 1. Green environmental protection method: put more bonsais on the roof. If you are busy, you don't need to take care of more. If the roof on the top can bear the load, the insulation is to make a sky garden -- that is, find some soil on the roof and plant plants. 2. Wooden box type insulation can be done by yourself. The size of the wooden box depends on your house, and it is filled with foam insulation boards! Pay attention to fireproof treatment on wooden cases! 3. Suspended ceiling insulation (indoor): but it reduces the indoor space. Paint keel mineral wool board or insert board ceiling can effectively insulate heat. Either add a layer of insulation board on the wall of the living room or paint a layer of insulation layer around the living room. 2. There are many long-term effective waterproof and thermal insulation methods for the roof. The price varies according to different materials: 1 The air circulation heat insulation method is to cover a hollow interlayer about 30cm on the roof. When the sun is exposed in summer, the flowing air below can effectively isolate the heat transfer effect, This roof insulation method can effectively and reasonably reduce the indoor temperature and is relatively simple. 3. The white glossy paper reflection method, as its name implies, is to lay a layer of smooth white glossy paper on the roof, which is made of tin foil, not easy to be stained with oil, and can strongly reflect and insulate. 4. Pearl sand insulation layer Now there are many roof insulation methods, and a 10 cm thick pearl sand insulation layer can be laid on the roof, Then a layer of cement prefabricated insulation board can be made; If it is a reinforced concrete cast-in-place roof, a 20 cm thick soil layer can be stored on it for greening and planting flowers and plants, which not only beautifies the bad environment, but also has the function of heat insulation. 5. The invention discloses a roof leak proof and heat insulation method, which is to cover the whole roof with glass steel plate and bond the glass steel plate as a whole. Compared with the prior art, It has the advantages of easy construction, high material strength, light weight, long service life, good leak proof and heat insulation effect, etc. 6. Ceramsite concrete heat insulation, such as the method of laying ceramsite concrete heat insulation on the top floor, can greatly reduce the indoor temperature, not only can have a comfortable summer, but also can effectively save power consumption and reduce the cost of electricity. In addition to the ceramsite concrete as the roof insulation layer, With the effective heat insulation, it has also played a very good moisture-proof and waterproof effect. Now ceramsite concrete has been widely used as toilet backfill and roof insulation layer. Relevant recommendations How to make waterproof and thermal insulation of old building roof simple and easy? How to deal with the roof and ground? How to do the roof insulation layer? How to make it both affordable and practical? The roof insulation layer is a better way to make the roof insulation layer. In summer, the roof insulation coating is better. Is the roof sunscreen useful? Is the roof waterproof, heat insulation and cooling treatment done once again.

When purchasing decoration products, many people attach great importance to brands. Excellent brands not only guarantee the quality, but also show the taste of the decoration effect, so that others can see the uniqueness of home decoration. There are many brands of decoration products, which are inherited and developed in the market with their own characteristics. How should you choose? What is good for home decoration wall? 1、 There are many good wall decoration materials for home decoration, such as latex paint, wallpaper, diatom mud, ceramic tile, etc. At present, the number of people who use latex paint should be the largest. Latex paint has the following advantages: 1. Environmental friendly latex paint uses water as the dispersion medium, does not contain organic solvents or only a small amount of organic solvents, so during production and construction, There is no or almost no organic solvent volatilization, which will cause environmental pollution and harm to human body. During transportation and storage, there is no danger of explosion and fire. It belongs to the category of water-based paint, and is a kind of resource saving, safe and environmentally friendly paint. 2. Convenient construction. Latex paint can be brushed, roller coated, sprayed It can be diluted with water. Brushing tools can be easily cleaned immediately with water. When not in use for a short time, the brushing tools can also be immersed in water or sealed with plastic bags Good air permeability latex paint is formed by evaporation of water and deformation and fusion of latex particles, so it has good air permeability, Only people can use it. The same is true for latex paint, which can play a role in both decoration and protection in the field it is involved in and used. Second, what kind of waterproof material is used for the wall of home decoration? In the waterproof of home decoration, we generally need to make kitchens, bathrooms, and balconies, including if your home is on the ground floor, Then all floors and walls below 1.5m away from the wall need to be treated with waterproof and moisture-proof treatment. Different waterproof materials are suitable for different parts of the wall. The waterproof materials on the wall are the same as those on the ground, so you only need to know the waterproof materials suitable for each part of the home decoration. It is recommended to use kitchen and bathroom waterproof mortar in kitchens, bathrooms and basements, It is specially developed for the internal and external corners, pipes, sanitary wares, floor drains and other surrounding areas that are prone to water seepage in kitchen and bathroom. Therefore, it is specially made, more targeted, and the waterproof effect is certainly better. For balcony, roof, terrace, etc., it is suggested that K11 waterproof mortar flexible type and mortar waterproof agent should be combined for construction, so that the combination of hardness and softness can resist the erosion of sun and rain, Ensure good waterproof effect. 3. Related concepts 1. Emulsion paint, also known as synthetic resin emulsion paint, is a kind of organic paint. It is a kind of water-based paint prepared with synthetic resin emulsion as the base material, pigments, fillers and various additives. According to different production materials, latex paints mainly include polyvinyl acetate latex paint, ethylene propylene latex paint, pure acrylic latex paint, styrene acrylic latex paint, etc. According to the different application environments of the product, it can be divided into interior wall latex paint and exterior wall latex paint. According to the gloss effect of decoration, it can be divided into matte, matt, semi gloss, mercerized and glossy types. Latex paint has many advantages different from traditional wall coatings, such as easy brushing, rapid drying, etc. The methods to identify latex paint include looking, smelling, wiping, brushing, pulling and testing. 2. Paint coating is a kind of viscous liquid that is coated on the surface of protected or decorated objects and can form a continuous film firmly attached to the coated objects. It is usually made of resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, and is prepared with organic solvent or water. The more authoritative book "Coating Technology" in the Chinese coating industry defines as: "Coating is a kind of material, which can be coated on the surface of objects with different construction processes to form a solid film with firm adhesion, certain strength and continuity. The film formed by this is commonly called coating film, also known as paint film or coating." In the early days, most of the coatings used vegetable oil as the main raw material, So it is called "paint". Both traditional coating products with natural materials as raw materials and modern developing coating products with synthetic chemical products as raw materials belong to organic chemical polymer materials, and the film formed belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products.

In fact, there are priorities when decorating. No matter what social class you are, you should spend your money where you should be, so that there will be no potential safety hazards at home. Moreover, the decoration is like a bottomless hole. Fifty or sixty thousand yuan can be used to decorate a suite, and fifty or sixty thousand yuan can also be used to decorate a suite. So it is correct to choose the materials that are suitable for you. Today, I will tell you about the waterproof leak sealer in the toilet. How much do you know about the waterproof leak sealer in the toilet? Why don't you take a look with me. 1、 The traditional concept of waterproof leak sealant is to make up where the leak is. The latest method of waterproof leak repair is to abandon this traditional concept. If the waterproof layer leaks, do a good job of waterproof and leak proof outside the tiles. As long as the surface of the tiles outside is waterproof, the waterproof effect is the same. Waterproof construction method: use a knife to remove waterproof cement or glue between tiles, use a dryer to dry the floor for a day, and then fill the gully with cement of the same color as the floor (if the floor is white, use white cement to fill it; if the floor is black, use black cement to fill it, for the sake of indoor beauty) Then slowly inject a special CPC waterproof agent into the cement. After 1-2 days, the waterproof agent and cement will be firmly adsorbed on the tile, effectively forming a stable waterproof layer. 2、 What are the waterproof and leak stopping techniques in the toilet? 1. The wall must be waterproof. Before the wall tiles are paved, the wall must be waterproof. In general waterproof treatment, the wall must be waterproof with a height of 30 cm, and the non load-bearing light wall must be at least 60 cm high. It is better to waterproof the whole wall. 2. The joints between the wall and the ground and the joints between the water supply and drainage pipes and the ground are the places most prone to problems. Workers must be urged to handle these corners. Waterproof and leak stopping coatings must be applied in place, and it is best to strengthen the layer. 3. If it is necessary to replace the original floor tile in the bathroom, after the original floor tile is chiseled off, the floor must be leveled with cement mortar first, and then the waterproof plugging treatment must be carried out, so as to avoid leakage of waterproof coating due to uneven thickness. Before waterproof, the floor must be cleaned. 4. Try not to damage the original waterproof layer. A waterproof layer has been made on the general ground of the newly delivered building, so no leakage will occur if the original waterproof layer is not damaged. 5. The decoration team is required to make cement mulch for all the water pipes in the toilet, brush waterproof paint from the ground up by 10 to 20 cm, and then redo ester waterproof on the ground, and add the original waterproof layer to form a composite waterproof layer to enhance the waterproof. 6. The groove of the water pipe in the wall shall also be waterproof. During the construction process, when the pipe, floor drain, etc. pass through the floor, the waterproof layer around the hole must be carefully constructed. The water pipe shall be buried in the wall, and the reasonable layout shall be achieved. When laying the water pipe, the groove shall be made larger than the pipe diameter. The groove shall be plastered smoothly, and then the groove shall be painted with waterproof paint. 7. The 24-hour "water storage test" is used to check and accept the waterproofing. After the waterproofing works are completed, the door and the water outlet are sealed. The toilet floor is filled with water to a certain level and marked. If there is no obvious drop in the level within 24 hours, especially if there is no leakage on the roof of the house downstairs, the waterproofing and leakage blocking are qualified. 3、 Relevant concept 1, plugging is a construction measure! It is mainly used in waterproof containers or measures commonly used when the foundation leaks. 2. Waterproofing is no longer a new topic, whether it is tunnels, bridges, dams, roads, buildings or our daily living houses, waterproof can not be ignored. At the same time, the electrical products used in our daily life also have waterproof and moisture-proof problems that must be faced directly. Source: Records of the Historian? Chronicle of the Zhou Dynasty: "Zhao Gong said, 'It's the name of Zhang. It's better to guard against the mouth of the people than against water.'" In Guoyu, it says, "Prevent Sichuan.".

During the decoration, our decoration budget is always overspent, which seems to be an ordinary thing in the decoration, but when you think about it, the overspent money is not worth it at all. So we must shop around when choosing decoration products. Because it is troublesome to do waterproof in the toilet, many people want to do waterproof without knocking tiles when doing waterproof in the toilet. Is it reliable to do waterproof without knocking tiles? Let's have a look. 1、 Of course, it is safe to use waterproof agent without knocking ceramic tiles. Use waterproof agent without smashing bricks in kitchen and bathroom. This is specifically aimed at water leakage after laying ceramic tiles. As long as the pipeline is not broken, the waterproof agent without smashing bricks can be treated, which saves time and labor, and is economical. Waterproofing can only be done from the ground. If it is leaking from the ground, you can use glass glue to hook all the brick joints. But you can't stay long, After several years, no matter what you use for pointing, you can't stay for several years. It's the best way to knock on the tiles. How to use the waterproof agent without smashing bricks in kitchen and bathroom: 1. Use a screwdriver or wallpaper knife to remove and clean the loose oil sludge and other dirt in the floor tile joints. 2. Use a plastic bag to wrap the rag to block the floor leak, Infiltrate the kitchen and bathroom non brick smashing waterproof agent into component A, dilute it with 3 times of clear water, pour it on the floor tile, and sweep it from the low to the high with a broom for 3 hours to make the waterproof agent leak evenly into the floor tile seam (if the waterproof agent leaks in less than 3 hours, immediately proceed to the next process). 3. Release the residual waterproof agent permeable component A from the floor drain, and clean the floor at least three times with a mop to ensure that it is fully clean, Re plug the floor drain; Dilute the crystalline component B of waterproof agent with 3 times of clear water and pour it on the floor tile. Sweep the floor tile with a broom from the low to the high for 3 hours to make the waterproof agent leak into the floor tile seam evenly and fully (if the leakage is completed within 3 hours, the next process shall be carried out immediately). 2、 How much does it cost to do waterproof without knocking tiles? Whether it is necessary to do waterproof depends on the cause of water leakage, Only in this way can we solve the problem fundamentally. The amount of money for waterproofing should be considered from two perspectives, one is the material problem, and the other is the construction problem. Waterproof material. It depends on several materials, whether they are non-standard materials or national standard materials. It's cheaper than 10 yuan. Qualified, a course of material costs about 40 yuan. Take the traditional SBS modified asphalt roll as an example, from more than 100 yuan per roll to 600 yuan per roll, and the construction team's labor and material contracting price ranges from more than 20 yuan per square meter to 5 yuan, 60 yuan or even 70 yuan per square meter. The cost of materials accounts for 60~65%. Generally speaking, about 20 yuan and 30 yuan are non-standard products, that is, unqualified products. 3、 Related concept 1. Toilet and toilet are the collective name of toilet, toilet and bathtub. Toilets in residential buildings are generally divided into dedicated and public toilets. Dedicated only for master bedroom; The public ones are connected with the public walkways and shared by other family members and guests. According to the layout, it can be divided into independent type, dual-use type and compromise type. According to the form, it can be divided into semi open type, open type and closed type. At present, the semi open type that distinguishes dry and wet zones is popular. 2. Waterproofing is no longer a new topic, whether it is tunnels, bridges, dams, roads, buildings or our daily living houses, waterproof can not be ignored. At the same time, the electrical products used in our daily life also have waterproof and moisture-proof problems that must be faced directly. Source: Records of the Historian? Chronicle of the Zhou Dynasty: "Zhao Gong said, 'It's the name of Zhang. It's better to guard against the mouth of the people than against water.'" In Guoyu, it says, "Prevent Sichuan.". 3. Leakage repair refers to the repair of leakage of building facilities. Relevant recommendations: Tips for preventing leakage in toilet decoration Waterproof and leak stopping in hotel bathrooms Do not knock ceramic tiles, do not break ceramic tiles, do not leak in bathrooms Waterproof agent in bathrooms is better than that of better brands. Do you want to do waterproof and leak stopping when pasting ceramic tiles on the walls of bathrooms? Tell you whether the beautiful seam treatment of ceramic tiles after waterproof and leak stopping in bathrooms must do waterproof on the walls of bathrooms? Will the waterproof tiles on the walls of the toilet and kitchen affect the firmness of the tiles? Does the waterproof layer of the toilet wall affect the tiling? Key points of waterproof construction techniques for household toilet

Due to limited funds, many people prefer small size houses when buying houses. This kind of residential space is relatively small, which poses a problem for owners. How to decorate living rooms, bedrooms, kitchens, toilets and other living spaces in such a small space? What are the design methods for small apartments? How to waterproof the small bathroom after tiling? Now I will share with you how to make waterproof after tiling, and I hope it can help the friends in need. 1、 How to make the toilet with ceramic tiles waterproof 1. Knock off all the ceramic tiles in the toilet, and then trowel the exposed substrate with cement mortar to make it flat, firm, clean, and free of dust, grease, and other debris; The pipe opening through the wall must be filled; The corner of the wall shall be plastered into an arc shape; Ensure that the prepared base surface is fully wet, but there is no clear water; 2. Pour the liquid material into the container, and then slowly add the powder material. At the same time, fully mix for 3-5 minutes until a uniform slurry without raw powder and particles is formed; (It is better to use a mixer) 3. Brush directly on the base surface with a brush or roller brush, and use the force evenly without omission; Generally, it needs to be painted twice (depending on the use requirements), and the thickness of each painting shall not exceed 1mm; The previous one is slightly dry and then the next one is painted (just not sticky, usually 1-2 hours apart), and the front and back two times of vertical cross brushing, with a total thickness of 1-2mm; If the coating has solidified, wet it with clean water before painting another layer. 4. Protect it from trampling, rain, sun exposure, sharp damage, etc. before fully drying after construction. 5. Closed water test: store water for 48 hours after the waterproof layer has dried and solidified (at least 24 hours in summer and 48 hours in winter) to check whether the waterproof construction is qualified. If there is no water leakage, the waterproof coating is successful. 6 If only a few bricks are replaced, brush two coats of waterproof paint at the place where the road is replaced, paste the tiles after the waterproof layer is completely dry, and fill the gaps between the tiles with ultra fine seam mold proof sealant. 2、 How to stick the wall tiles after the toilet is waterproof? 1. You should be on the site, and workers will not waste tiles. It is suggested that some imperfect tiles can be stuck in some positions that cannot be seen in the future, such as behind the cupboard, washstand, mirror, etc. Pay attention to that the tiles, waist tiles, etc. should not be stuck in the above positions by workers. 2. Before tiling, make the wall as rough as possible, This can increase the contact force area between the cement and the wall. The specific method is to use an electric drill to drill more holes on the wall, the more the better, When tiling on the wall of the kitchen and bathroom with pipes wrapped, 108 glue must be added to the cement mortar to increase the adhesion. 6. To prevent hollowing, check that the hollowing of ceramic tiles cannot be knocked just after pasting. It is better to wait for two or three hours before knocking. Pay special attention to the four corners of ceramic tiles. Knock one by one. When hearing hollowing, you must rework. Don't be soft hearted. 7. The floor of the toilet must slope to the floor drain, and properly increase the slope. When decorating the pipes in the toilet, you should try to avoid changing the original drainage and sewage pipes and the location of the floor drain, Avoid leakage caused by damage to the waterproof layer caused by re laying pipes and chiseling floors. 8. If the color of the tile jointing agent is mixed with toner, it is better to debug it first and then determine the amount, otherwise it is either too shallow or too deep. 9. The slope of the bathroom decoration floor should be considered before laying bricks. According to the national standard slope, rapid drainage cannot be achieved, And if you use an odor proof floor drain or an ultra-thin floor drain, it will greatly increase the difficulty of drainage. 3、 Related concept 1. Ceramic tile, also known as ceramic tile, is an acid and alkali resistant ceramic or stone material formed by grinding, mixing, pressing, glazing, and sintering of refractory metal oxides and semi metal oxides. Building or decorative materials are called ceramic tiles. Its raw materials are mostly mixed with clay, quartz sand, etc. 2. The tile on the tiled wall must be firmly pasted, and the hollowing rate is within 3%. There are no defects such as skew, missing edges, corners, cracks, etc. The wall tile paving and sticking surface shall be flat and clean, with harmonious color and reasonable pattern arrangement, without discoloration, efflorescence, stains and obvious gloss damage. Brick joints shall be filled tightly, straight, uniform in width, consistent in color, and lapping direction at internal and external corners shall be correct. The non whole bricks shall be properly used and arranged in a straight manner. The reserved holes shall have correct size and neat edges. Check that the flatness error is less than 2mm, the vertical error of the facade is less than 2mm, the height deviation of the joints is less than 0.5mm, and the flatness is less than 2mm. 3 Floor drain refers to the drainage appliance connecting the ground and the drainage pipeline system, which is an important interface between the drainage pipeline system and the indoor ground, and is an important part of the drainage system in the residence, Its performance directly affects the quality of indoor air, and is very important for odor control in bathroom. Relevant recommendations: There are so many bathroom floor tiles. How about the bathroom floor tile on the wall? There is a hollow bathroom floor tile. Wet paving method: Dongpeng all ceramic bathroom tile. Can it be used as the bathroom floor tile? Large tile on the wall. There are shortcomings in the bathroom. Paint the waterproof layer to make the bathroom waterproof with half the effort. Bathroom floor tile waterproof caulking. Bathroom tile maintenance tips

No matter what style of decoration and what materials are used in home decoration, it is very important to choose a brand. Some people like this brand and others like another brand. In fact, this topic has always been a topic of debate. Home decoration materials determine the quality of decoration. Nowadays, consumers pay more attention to brand quality than to the price of products. Let's have a look at the bathroom waterproof without brick smashing for information. 1、 First of all, if the original waterproof layer is damaged, it will seep from top to bottom. In this case, it is OK not to pry the floor tiles; However, if the water pipe buried below is broken, it is recommended to replace it by prying bricks, and then make waterproof again. If you can't find the cause of water leakage, you can first do a test, block the floor drain, pour water on the ground, and then observe whether there is water leakage downstairs. If there is no water leakage, it is just a problem of surface water leakage. There are two methods when the floor tile is not moved, one is pointing, the other is grouting. If pointing, first clean the gap of the floor tile, then fill the tile seam tightly with special brick free waterproof agent, and then apply sealant on the corner and bathing area. However, this method is difficult to operate and requires a skilled worker. As for grouting, it is necessary to clean the cement joints around the floor drain and water, dispose of the water on the ground, and then grout or put some glass glue into it. After it is completely dry, it is necessary to see whether the water can be drained in time. 2、 Whether the waterproof effect of the bathroom without smashing bricks is good or not 1. When the water source is cut off, the first thing to do is to find the place where the water seeps, and make the water pipe buried under the tile into an open pipe, so that even if the water pipe breaks, as long as the water source is cut off, there will be no water leakage, and it can also play a waterproof role. 2. Clean the gaps between the tiles for neat cement waterproofing, especially the cement gaps visible in the bathroom. Then use neat cement and clean water to mix well, use a brush to dip in the neat cement, and evenly brush it into the clean gaps for several times, which can also play a waterproof effect. 3. The waterproof of professional leak stoppage products is similar to the second waterproof method. First, clean the gap between sanitary tiles and ceramic tiles, and clean the cement gap in the toilet. Prepare according to the relevant instructions of the product, and also use a brush to paint in the gap. The speed should be fast, and brush more times. The waterproof method of brick smashing free in the toilet is used to block water seepage and leakage. Is the final waterproof effect good? Apart from environmental protection, the brick free waterproof material flows into the mortar layer through the tile gap, and the saturation of the toilet with water leakage is already very high, so the mortar can not fully enter into the seepage layer when it continues to be used. Even if a small amount of mortar is entered, the waterproof effect is relatively low. The first thing to know is to find out the location and cause of water leakage when using the waterproof method of non smashing bricks in the toilet, so that we can solve the problem with non smashing bricks. For the maintenance scheme without smashing bricks, corresponding solutions should be designed according to different environments of the toilet, and construction materials with different properties should be used to achieve long-term waterproof of the toilet. 3、 Relevant concept 1. Waterproof and waterproofing is no longer a new topic. Waterproof can not be ignored in tunnels, bridges, dams, roads, buildings or our daily houses. At the same time, the electrical products used in our daily life also have waterproof and moisture-proof problems that must be faced directly. Source: Records of the Historian?

Plugging is a construction measure! It is mainly used in waterproof containers or measures commonly used when the foundation leaks. 3. The toilet is the collective name of toilet, washroom and bathtub. Toilets in residential buildings are generally divided into dedicated and public toilets. Dedicated only for master bedroom; The public ones are connected with the public walkways and shared by other family members and guests. According to the layout, it can be divided into independent type, dual-use type and compromise type. According to the form, it can be divided into semi open type, open type and closed type. At present, the semi open type that distinguishes dry and wet zones is popular. Relevant recommendations: Can the brick free waterproof be repeated?

House decoration, for a family, the waterproof method of bathroom wall is very important, not only to protect family safety, but also not affect others. If you do not do a good waterproof when decorating, it will also have an impact on the vision and practicality of the whole home. So it is very important to choose suitable home decoration materials for your own home. We introduced the waterproof method of bathroom wall separately, and let's take a look at the waterproof method of bathroom wall together. 1、 How to waterproof the walls and floors of toilets? The flexible waterproof coating should be used for the waterproof treatment of the walls and floors. The waterproof layer should be applied vertically and horizontally to ensure the tightness of the waterproof layer. The waterproof height of the wall in the kitchen and bathroom wet areas (such as bathrooms and bathtubs) should not be less than 1800mm, and the waterproof height of the wall in the dry areas should not be less than 300mm. Water storage test must be carried out on the structural floor of the toilet. The general contractor is responsible for water storage. After the water storage test is completed, it needs to be signed by the supervisor, the owner and the general contractor as a handover and acceptance procedure. After the completion of the floor drainage system and the completion of the waterproof layer of the decoration construction, the decoration construction unit shall conduct water storage test again. Water storage test is strictly prohibited before the waterproof layer is dry, If the water becomes turbid or milky white during water storage, it indicates that the curing time of the waterproof layer is not enough, the waterproof layer has been dissolved and damaged by water, and the waterproof failure must be redone. 2、 Waterproof method of toilet wall: 1. Brush waterproof paint once. Before construction, ensure that the construction site is clean and dry. The waterproof paint should be fully applied without omission. It should be firmly combined with the base course without cracks, bubbles or falling off. The painting height should be consistent and the thickness should meet the product requirements. 2. Brush the second layer of waterproof paint. Note that there should be a certain time interval between the second layer of waterproof paint, The second coat can be carried out only after the coating is completely dry. The specific time depends on the coating. If the interval is too short, the waterproof effect will be greatly reduced. 3. Lay a protective layer. To prevent the waterproof layer from being damaged by subsequent construction, it is necessary to lay a protective layer on the surface of the waterproof coating. The protective layer should completely cover the waterproof layer, without omission, firmly combined with the base layer, without cracks, bubbles, or falling off. 4 Closed water test. During the closed water test, the waterline of the ground point shall not be less than 2 cm, and it shall be kept for at least 24 hours. It shall be regarded as qualified after no leakage is observed. If there is any leakage, it shall be redone, and no negligence is allowed. 3、 Relevant concept 1. Waterproof layer Waterproof layer: a material layer designed to prevent rainwater from entering the roof, groundwater from infiltrating into walls, basements and underground structures, and indoor water from infiltrating into floors and walls. 2. Waterproofing is no longer a new topic, whether it is tunnels, bridges, dams, roads, buildings or our daily living houses, waterproof can not be ignored. At the same time, the electrical products used in our daily life also have waterproof and moisture-proof problems that must be faced directly. Source: Records of the Historian? Chronicle of the Zhou Dynasty: "Zhao Gong said, 'It's the name of Zhang. It's better to guard against the mouth of the people than against water.'" In Guoyu, it says, "Prevent Sichuan.".

The article is from New Audio, February 2017. On the right side of the body is a Type-C double-sided USB charging interface and a card slot that supports high-capacity SD cards. The original factory attached a 16G high-speed card full of test content. TECSUN is a newcomer in the hi fi sound industry, but if we broaden our attention to the radio field, then everyone knows the great reputation of Tecsun. Founded in 1994, DeSheng has been focusing on radio, and has an incomparable position in the field of radio. Sound is this. Liang Wei, the boss of Desheng, who graduated from South China University of Technology in the early years, has been keen on radio since childhood and likes tossing about. He has never stopped studying radio and sound technology since he graduated from college in 1982, whether in middle school or as an educated youth. He has a very persistent pursuit of product development and quality. He is a typical craftsman. I have known Mr. Liang for a long time, but it was only a year or two ago that I really made contact with him. Every time I met with Liang Sheng, I would always see him playing with some new products. He enthusiastically and unreservedly communicated his development experience with others and solicited their opinions. After decades of product development, we can still maintain our entrepreneurial passion, which is really valuable! Although Mr. Liang has achieved success in the radio industry, his love for good music and sound over the years as a Singer has inspired him to develop hi fi products. So we saw the HD100 high fidelity music player prototype in 2014. Unfortunately, due to the CPU performance constraints in the early years, this product could not keep up with the demand for reading speed and was not put into production in large quantities. However, the exquisite appearance design and exquisite workmanship are refreshing. Later, Desheng learned a lesson and developed a series of audio products, such as HD80 audio butler, power amplifier and speaker. At the same time, it also made more exploration on the sound and functions of traditional radio products, developed a very cost-effective B5 Bluetooth digital player, and a V5 Bluetooth/Wi Fi digital player with more perfect performance and technology, which soon became a hot item in the market. The new transformation of Desheng is really impressive. It should be the "grass root headset" that was launched at the end of last year. This headphone, which costs only 700 yuan, is made of walnut, wrapped with high-quality leather, and comes with a wooden packaging box. It is very simple and tasteful. What is more impressive about this "grassroots headset" is that it uses a large caliber driver unit with the same structure as a foreign brand's headset. However, the price of this foreign product with the same unit is 3-4 times that of "grassroots". The sound performance of "grassroots headset" is close to the level of 2000 yuan, and the performance ratio is self-evident. At the same time, Desheng also brought the HD80 digital player/front stage/ear amplifier all-in-one machine, which can form a relatively simple hi fi sound system only by connecting a pair of active speakers or power amplifiers. As the front stage of the sound system is powered by a large capacity battery, it completely eliminates the exchange of sound. This machine is not large in size and has its own high and low impedance monitoring earbuds. It can also travel with a pair of good headphones. It has a wide range of uses and excellent performance. Let's take a closer look at what HD80 can do. The knob on the left side of the display screen is the volume control on the top, the DSPEQ selection on the bottom, the charging indicator light and the recording peak indicator light. The two small buttons on the bottom are respectively the deletion of the DSPEQ function key HD80. At first glance, I always feel that the appearance of the machine is a bit different. The pure plastic shell also lacks a sense of quality, but when it is actually used, The HD80 is placed on the desk, but the design is very humanistic. The dashboard like knob and key layout is reasonable, and the deliberate control interface combines traditional and modern usage habits, which is easy to use; The slightly inclined panel makes it easier to view the display screen. The screen is not large or small, and the pixel seems not too high, but it can clearly display all information. For example, the file name is neatly displayed on each directory layer entering the file menu, the playing track shows the progress in the form of time axis with numbers, and the volume is also scaled with numbers to clearly display the status when adjusting the volume, Adjust EQ and other options are clearly displayed. Different function knobs and keys are arranged on the left, right and lower sides of the display screen. There are two small knobs on the left, the upper knob is used for volume adjustment, and the lower knob changes the equalization mode; On the right is a large multi-function knob for menu/track selection and confirmation. The lower two rows of keys are recording/playing/selecting/EQ equalization/playing status and other functional options. There are two 3.5mm monitor earphone output jacks on the lower left side of the fuselage, which correspond to high and low impedance earphones respectively, to adapt to the drive of various impedance earphones. The actual effect is excellent. There is a USB socket and an SD card socket on the right side of the machine. The original machine is delivered with a 16GB high-speed SD card, which is full of test audio and various music files. Of course, players can change the SD card or copy their favorite content at any time. Looking at the back of the machine, you will suddenly find that this compact HD80 is equipped with stereo RCA input and output ports, indicating that HD80 can also be connected to external analog inputs, with digital and analog front-end functions, and the output port is used for external rear power amplifiers. In addition, HD80 is also equipped with a B-type USB interface that can be connected to an external computer for USBDAC use. What's more surprising is that HD80 can record analog input audio, transcribe audio input signals into 24bit/48k or 24bit/96k wav format files, and store them in memory or SD card. This brings more playability to HD80, for example, it can be connected to the analog output of the SACD machine with good sound quality, expensive and difficult to track, and directly "track grasping"; It can also be connected to a phonograph amplifier to record the analog music of black glue into digital files; Connect the tuner and record the broadcast sound worth saving; When karaoke, you can connect to the line output of the wireless microphone for live recording! In addition, HD80 also has high/low recording level control, and recording is an overload peak level indication. All the above functions can be operated through the full function remote control. In addition, the HD80 has two 18650 mA lithium batteries in parallel for power supply. I measured that the endurance time is at least 10 hours. The DC power supply completely avoids the noise interference that may be introduced by the AC power supply, so the sound performance is cleaner and more pure. Above the back of the fuselage is the battery box door, which contains two 18650 mA lithium batteries for parallel power supply, with a total capacity of 5200 mA. The measured endurance is more than 10 hours. The pictures of the lower row of various input and output terminals are from left to right, which are coaxial input, B-type USB input, RCA analog input The RCA analog pre output is a satisfactory digital broadcast audition process. I can copy the usual audition files into the SD card, which is more convenient. I have also used the USB cable of SoundArt to connect to the computer, but I always feel that the convenience is not as good as HD80 for direct digital broadcast. In terms of sound quality, I really can't hear how much difference there is. HD80, as a digital broadcast and pre stage, is connected to the E50 integrated camera on the high shift. The volume of HD80 is fully turned on and controlled by the camera. In fact, you don't have to worry about distortion when HD80 output is too high, and you can also get a larger dynamic performance. Of course, you can also preset the volume of the power amplifier and use HD80 to control the volume of the audio system. Compared with the Soulnote entry-level S300 CD player, the HD80 is 50% cheaper than the S300. Is the sound far away? In fact, by comparing the CD of the same recording with the track grabbing file, HD80 is obviously more stable and beautiful than the S300 in timbre, with a wider sound field. It is an undisputed fact that HD80 is more balanced and transparent when replaying records of various styles, with better sound effects. When the symphony is replayed, HD80 can provide a delightful sound effect. Its reception and playback are more attractive from the following low-frequency parts with prominent potential and distinct knot image. This unexpected result really surprises me. In the past, the weak point of low price digital broadcasting was that its low frequency performance was not good, and it was often expected only in the aspects of timbre fineness, analytical power and natural purity. Now I can actually see its outstanding performance in low frequency on HD80, so I have to ask Mr. Liang: How did you do it? HD80 has excellent control over low-frequency play and play, and its powerful sound effect can still be felt even if it replays Hugo's Yellow River Steel Association. In this respect, the more expensive CD player can't take advantage of it. To some extent, I think HD80 has better effect. In addition, the full frequency speed of HD80 is so good that it is hard to believe that such a small digital broadcast is responsible for it. Its speed is fast enough, but there is no sense of mechanization. Its sound quality is as active as that of more advanced CD players. In fact, HD80's performance is very balanced. It does not show off tricks. The full frequency thickness is moderate, and the timbre is fine and not hard. Although the sound quality is not silky smooth and shiny, and there is still no rich glycol level of superior red wine, the HD80 replayed records, whether vocal, violin, piano, guitar or electronic synthetic music, always give me a sense of intimacy. All types of recordings are always so easy to listen, without the urge to change songs. The main menu is displayed with icons and text, which can intuitively and clearly enter the memory or SD card folder selection interface, and can intuitively view the music in the selected folder. The correct error free recording function menu interface is displayed in both Chinese and English. The storage location, recording specification and input attenuation can be selected and then compared in depth. I have to be frank and frank, Compared with the S300 CD player, the HD80 performs better because it can reproduce a more in-depth sound field, a stronger potential at low frequencies and a more natural extension at high frequencies, which brings about the enhancement of music performance in the true sense, that is, the amount of music information is more abundant, and the life of music is fuller and more vigorous. For example, when Perlman's "The List of Cindela" is replayed, the timbre of the violin is more sad and lingering, and the resonance of the piano cavity is more qualitative. It is not so noble and gorgeous, but the details and overtones can also be completely reproduced. The music files replayed by HD80 always have more music information and show a broader music space. For example, the South American Mass played by tenor Carreras is replayed. The recording quality of this record is very high. The song is simple, sincere and rich, without any trace of affectation. The record is more prominent in the presentation of the sound field, broad and profound. When HD80 replays, the obvious feeling is that the depth is one third to one quarter longer than S300, and the hidden background is also particularly "quiet". Although the size of the chorus group does not give people a larger feeling, the sense of entity of mouth shape interpretation is obviously strengthened, with a clearer sense of positioning. The middle and low frequencies of the S300 are a little messy. The HD80 is well controlled, and has more natural flexibility, becoming more calm and powerful. Carreras' voice has more moisture, and his singing is more leisurely. Compared with his elastic singing voice, he also has a more natural warmth, which is hard to realize on the S300 CD player. As an ear amplifier, HD80 is very competent. It has two headphone jacks, high and low impedance. I believe that Desheng has made great efforts to design the ear amplifier. So the audition also found Desheng's own "grass root earphone" and HiFimanHE1000V2 earphone for audition. Driven by the "grassroots headset", the HD80 is really handy and skilful, with outstanding performance in both dynamic and sound fields. When HE1000V2 is inserted into the high impedance interface, the driving force of HD80 is just enough. The dynamic is not as leisurely as driving the "grass roots", but the overall sound quality is thicker, the colors are more colorful, and the sound field is larger and wider. For example, the rebroadcast of Giles' Beethoven's "Enthusiasm", the resonance generated by the rich and subtle vibration of the piano sound, was so rich and dense. Before this, many medium and high price portable digital broadcasts could not provide such a powerful sense of hearing. The dynamic and air feeling from high to low frequencies could be described as gorgeous and generous, which really surprised me. The HD80 earphone has accurate and exquisite sound, rich musical sense, grand dynamic, deep and wide sound field, and gorgeous timbre, which is exactly the sound of the digital audio amplifier I hope to have. The interface displayed when playing music has clear information. Please pay attention to the file format and bit rate information at the bottom left, HD80 perfectly supports the replay of DSD files. I can't find fault with HD80's sound performance, functionality and handling experience at this price. The only thing I can't make up my mind is the appearance style. I sincerely hope that in the future, Desheng can launch upgraded products based on the price of HD80 and HD100, so I have no reason to hesitate. Netizens commented on the old gas bar factory

The products are exported to more than 40 countries and regions such as Germany, Brazil, Venezuela, Poland, Turkey, Angola, Nigeria, South Africa and India. Financial data perspective According to the semi annual report of 2016, in the first half of the year, the company realized an operating income of 216 million yuan, a year-on-year increase of 9.05%, a gross profit rate of 38.12%, a year-on-year increase of 27.06%, a net profit of 21.5863 million yuan, a year-on-year increase of 31.6%, and a net cash flow of 4602600 yuan, a year-on-year decrease of - 71.21%. The increase in gross profit margin and net profit is mainly due to the fact that the main raw materials used for waterproof coiled materials are chemical and petrochemical products. During the reporting period, the prices of these products continued to fall. At the same time, the company optimized the production technology, improved the product formula, and the consumption of raw materials per unit product also continued to decline. In addition, foreign companies mainly provide overall waterproof solutions for the undertaken projects, which are mainly waterproof system projects, The unit construction profit also increased significantly than before. The reason for the decrease in net cash flow from operating activities is that the company's business was previously concentrated in northern China. Affected by the low temperature in winter, the first quarter of each year was the company's sales slack season. During the reporting period, the company's sales area expanded to the south and achieved some results. Due to the impact of the construction period, there were many projects that had not yet reached the settlement node in the reporting period. As a direct result, the cash flow from operating activities decreased compared with the same period last year. The rapid development of building waterproof material industry has resulted in overcapacity and low industry concentration. In recent years, the government has issued a number of policies. On the one hand, it has increased the elimination of backward production capacity enterprises to make their production meet new environmental requirements; On the other hand, we should improve the approval standards for enterprises with market access to ensure the production quality of enterprises. In the future, qualified and technology-based enterprises will be more popular. Since its establishment, Desheng Waterproof has been adhering to the concept of "building without demolition, waterproof without leakage", focusing on the production field of building waterproof materials, and has a high reputation; At the same time, adhere to the development and application of independent intellectual property rights, with industry-leading technological advantages; In addition, the company has advanced production equipment and high degree of production automation. In recent years, relying on its own accumulated patented technical products and construction team, the company has made great efforts to transfer from the traditional waterproof material supplier to the comprehensive service provider of waterproof system.
