Top ten brands of waterproof materials

What are the effects of seam sealants? Nowadays, living rooms, kitchens and bathrooms often encounter the problem of tile gaps changing from white to black, which is extremely unsanitary and beautiful. The problem of black tile gaps breeding bacteria has been overcome by seam sealants. What are the effects of seam sealants? Efficacy of seam sealant 1. The surface is as smooth as porcelain: after solidification, the surface of seam sealant is as smooth as porcelain, with high strength, abrasion resistance, excellent self-cleaning property, easy to clean, and can be scrubbed together with ceramic tiles; It is not easy to hide dirt and avoid mold growing in the gap to harm human health. 3. New materials and new processes: It is made of high-grade pigments and special additives of high-tech new polymer materials. It is different from white cement and colored joint filler (jointing agent) (low-grade pigment of dry powder cement material), which is mainly composed of inorganic materials. 4. Green and environmental protection: advanced materials, non-toxic, tasteless, free of benzene, toluene and xylene. 5. Convenient construction: easy to operate and learn. 6. The decoration effect is particularly strong: rich in color, natural and delicate, with luster and no fading, bringing better overall effect to the wall and floor (the color of the sealant on the market is dim and lusterless, and the color matching is limited). The seam sealant is applicable to the gap decoration of ceramic tile, mosaic, stone, wood, glass, aluminum plastic plate and other materials.

How to choose and purchase tile sealant? Tile joint beautifying agent is a high-end product for gap decoration, which is suitable for gap beautification of ceramic tiles, mosaics, stones, etc. Its surface is smooth, easy to scrub, and convenient to clean. How to choose and purchase tile joint beautifying agent? How to choose and buy tile sealants 1. Selection and classification: tile sealants include white cement, one component water-based sealants, two component oil-based sealants, two component water-based sealants, multi-component sealants and self leveling sealants. Generally, two-component oil-based sealants are more used in the market. 2. Smell: if the smell is large and there is a pungent smell, it indicates that the tile sealant has many harmful substances and is unhealthy. 3. See the curing time: the curing time of tile sealant is generally 4-6 hours, which needs to be extended in winter. The short curing time indicates that the chemical reaction is strong and harmful gases are easily produced. The long curing time indicates that the quality of the curing agent is poor. 4. Look at the color: after the tile sealant is dry, if the gloss is good and smooth, it means the quality is good; if the color is hard, the reflective intensity is strong, and the light is rigid, it means the quality is poor. 5. Look at the hardness: the harder the ceramic tile sealant is, the better it is. To be flexible and rigid, it should not only have a certain hardness, but also have good toughness. 6. Brand selection: There are many brands of sewing agent in the market, mainly including Degao, Zhuogao, Yuhong, Huangshi Craftsman and other brands. If you don't know how to choose, you can directly purchase famous brands.

What are the misunderstandings of ceramic tile adhesive? Tile pasting is a meticulous job, and the tile glue paving technique is also related to whether the tiles will be empty and fall off in the later period. Many friends will have various problems in the process of using the tile glue. What are the mistakes in using the tile glue? Misuse of ceramic tile glue 1. The ceramic tile glue mixed with cement, sand and other ceramic tile glue is already a well proportioned product, and there is no need to add other things. If added, the product proportioning will be damaged, and the quality cannot be guaranteed, and tile tiling is prone to hollowing, falling off and other problems. 2. Putting the tile glue on the ground and stirring it with a shovel will lead to the loss of effective chemical components of the tile glue; Secondly, it is impossible to mix evenly with a spade, and the proportion of water added by manual mixing is difficult to be accurate. The material ratio has changed, leading to the reduction of the adhesive force of the tile adhesive. 3. For a long time, it is incorrect to put the tile glue in the bucket and soak it with water. Some construction masters are accustomed to using the method of soaking cement to soak the tile glue. For a long time, the mixed tile glue is placed on the ground or in a bucket for soaking, which will easily lead to the lack of bonding strength of the tile glue, resulting in subsequent powder and brick loss. 4. If it has been used for a long time, some masters will mix the tile glue left last night with water and then add water and tile glue powder in the morning to mix. In fact, the effective components of the tile adhesive have chemical reaction due to the long time of placement. Adding water will only change its operating performance, resulting in insufficient bond strength in the later period; Tile glue shall be used as soon as it is stirred, the use time shall be controlled within 2 hours, and it shall be discarded after drying. 5. If the base course is not properly treated, the wall surface is not solid, the base course has defects such as oil stain and release agent, and the base course is not leveled, then tiles are paved. The low strength of the base course, uneven wall surface and greasy dirt will directly affect the adhesive force of the tile glue, leading to hollowing and brick dropping; The unqualified base course shall be treated before tiling. 6. The one-time glue coating area is too large, the surface of the glue is dry and solid, outdoor dry, windy weather, and the area of glue spreading and scraping is too large, and the construction time is too late, which will cause the surface to dry and solid before tiling, which will lead to brick falling; Use tooth scraper to scrape the glue evenly on the working surface. When tiling, the area of tile adhesive tape should be controlled within 1 square meter. In dry weather, the wall should be wetted in advance. 7. Uneven painting and incomplete kneading of ceramic tiles will cause a series of problems: (1) The corners of ceramic tiles are empty, which will lead to brick falling in a long-term humid environment; (2) The tile adhesive is uneven, and the tile adhesive is not firmly and completely bonded; (3) The tiles are not rubbed and pressed, and the glue is not firmly bonded.

Can ceramic tile glue be mixed with cement? All kinds of materials are also being updated step by step, and ceramic tile adhesive is one of them. In the past, most of our bricks were made of cement mortar, but now the technology is developed, and cement mortar has gradually been replaced by ceramic tile adhesive with better performance. Can ceramic tile glue be mixed with cement? Can ceramic tile glue be mixed with cement? Ceramic tile glue cannot be mixed with cement. Some ceramic tile glue will be mixed on the construction site, mainly to save money or cut corners. It can also speed up the drying time and make ceramic tile glue delicate. However, this will affect the performance of ceramic tile glue, leading to decreased adhesion, rotation and hollowing. Tile glue has many advantages, saving space, as long as a thin layer is enough, and the tiles are also very firm, reducing the use of waste materials, meeting environmental requirements, etc. 1. The water storage property of ceramic tile glue is very good, and cement can't compare with it. Ceramic tile glue can better delay the loss of water, so as to achieve more results. 2. Changing the ratio of raw materials of the product at will will inevitably lead to product failure. From the composition of the tile adhesive, we can see that its own composition is sand, which is adjusted according to a certain proportion. The formula of the tile adhesive is the core competitiveness of the product obtained through the constant experiment and practice of the tile adhesive brand manufacturers. We still have to follow the product instructions. 3. Although the price of cement is much lower than that of ceramic tile adhesive, a small amount of ceramic tile adhesive can achieve several times the super adhesive force of cement, which still reduces the amount of materials used. In addition, consider the safety of tiling and the expense of avoiding rework in the future. The ceramic tile adhesive contains a variety of additives, specifically the functionality of the ceramic tile adhesive. Generally, cellulose ether is added to ceramic tile adhesive to provide water retention and thickening, and latex powder is provided to increase the adhesive strength of ceramic tile adhesive. The most common latex powder is vinyl acetate/vinyl ester copolymer, vinyl laurate/vinyl chloride copolymer, acrylic acid and other additives. The addition of latex powder can greatly increase the flexibility of ceramic tile adhesive and improve the role of stress, Increase flexibility. Other ceramic tile adhesives with special functional requirements are added with other additives, such as adding wood fiber to improve the crack resistance and opening time of mortar, adding modified starch ether to provide slip resistance of mortar, adding early strength agent to make ceramic tile adhesive faster improve strength, adding hydrophobic agent to reduce water absorption to provide waterproof effect, etc.

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.

Many years ago, when the house was decorated, white caulking agent was usually used to make beautiful seams for the ceramic tile gaps at home, and the work was generally completed with the help of the master. Since the popularity of seam sealants, most of the caulking materials have been replaced by seam sealants. Many people think that making seam sealants is very simple, but in fact it is so simple! Construction steps of seam beautification: 1. Before the beginning of seam beautification, the dust and other sundries in the seam must be cleaned first! To clean the gap, we can use a utility knife or a seam cleaning cone, and then use a brush to clean the gap. If there is a vacuum cleaner, we can use a vacuum cleaner to clean the gap. The effect is better! 2. Sticker stickers shall be pasted horizontally and vertically along the edge of the tile gap, overlapping with the tile edge as much as possible. Do not paste it into the gap beyond the edge of the tile, which will cause the caulking material to not fit the gap completely! 3. After gluing and seaming with masking paper, the seaming will officially start. First screw the mixing tube onto the sealant bottle, then install it to the glue gun, and then inject the sealant at a uniform speed along the gap of the tile,. After the gap is filled, use the squeegee ball to scrape the sealant before it has cured. 4. The timing of tearing paper, wiping seam and tearing masking paper is very important. It needs to be torn off immediately after the masking agent is scraped, otherwise, after the masking agent is cured, tearing masking paper may bring the masking agent out of the gap, leading to the failure of caulking! There are not many steps for beautiful sewing, which can be summarized in one sentence: "one cleaning, two pasting, three scraping and four wiping". Is it much easier to remember this sentence? In the current beauty sewing market, if you find a professional beauty sewing construction team, the cost is still relatively expensive, so you can do it yourself. Although it is a bit hard, you can save a lot of money!

When decorating, many friends will choose seam sealer to paste ceramic tiles. It is inevitable that everyone will encounter various problems when doing seam sealer. Especially in summer, because it is humid in summer, what should be paid attention to when doing seam sealer in summer? Precautions for making beautiful stitches in summer 1. The storage temperature of beautiful stitches is between 10 ℃ and 30 ℃, and the temperature is usually higher than 30 ℃ in hot summer. Therefore, special attention should be paid to the storage of beautiful stitches. They should not be placed on the balcony where they are vulnerable to direct sunlight for a long time. They should be placed in a cool and dry place, and children should not reach them. 2、 Seam sealant construction has certain requirements for air, that is, drying. Therefore, the construction can be carried out only after the humidity is reduced. The method is to use hot fans, air conditioners, etc. to dry the indoor air. 3、 During the construction in rainy days, the doors and windows must be tightly closed to keep the room dry, because the rain is alkaline. If the doors and windows are not closed, the rain will enter the gaps in the tiles, and the beautiful joints will be jacked up after a long time. Not only that, but also use a dry towel to clean the gap, otherwise it is easy to have discontinuous whitening in the future. 4、 Due to the high temperature in summer, people are easily upset, and the sewing master is no exception. Therefore, pay attention to driving safety. 5、 Beautiful sewing is usually the last step of decoration. Painting and so on are finished before beautiful sewing. Therefore, indoor ventilation should be provided before beautiful sewing. This is for the health of beautiful sewing masters. 6、 If it is found that the tile caulking agent has returned to moisture before aesthetic sewing, the damp caulking agent shall be cleaned out, and then the dry caulking agent shall be filled in to absorb the moisture inside. Because the sealant is wet and water vapor evaporates, it is easy to penetrate into the sealant, making the curing agent in the sealant ineffective.

How to judge the quality of sewing agent? Now there are more and more sewing agent brands on the market, which are very messy. It is difficult for ordinary consumers to identify which is better. They also do not know how to judge the quality of sewing agent, and how to judge the quality of sewing agent? These eight standards must be known! The first of the eight criteria for judging the quality of joint sealant is that the hardness reaches the hardness of ceramic tile, so as to ensure the service life and not fall off. The second is that the toughness is slightly smaller than the toughness of ceramic tile, so as to meet the expansion joint of ceramic tile and prevent the separation and cracking of ceramic tile and ceramic tile? Third, the strength is high and the flatness is high, so as to ensure that the brick joint is flush with the brick surface after the seam beauty, and there will be no undercut of the seam beauty agent. Collapse is easy to hide dirt, easy to pollute, and difficult to clean. Fourth, it is colorless and tasteless, and can be constructed by hand. Fifth, it is green and environmentally friendly, and the material density is high, so as to ensure that it is fine and flawless, Is it a high standard sewing material that can't have knots? Sixth, the color should be bright and delicate, the color should be symmetrical, and the color should be diverse. High standard sewing materials should have 100% of all colors. Seventh, the bonding strength should be high, so as to protect the tiles from hollowing activities and protect the glaze. Eighth, whether it belongs to negative ion nano materials, high-quality sewing materials should not only be bright as porcelain, but also be hard as stone, Only the high strength seam that can be flush with the brick surface can achieve the permanent non dirty black and high-quality artistic seam effect!

Precautions for use of sealant? After the tiles are paved, they will be beautified with seam sealant in the gaps. In order to save money, some owners often choose to do it by themselves. This operation is very simple, but there are still some matters that need attention. What are the precautions for the use of sealant? Precautions for use of sealant 1. If the gap width of ceramic tile is less than 3mm, the gap depth of ceramic tile should be 0.5mm; If the tile gap width is between 3-5 mm, the tile gap depth is 1 mm; If the width of the ceramic tile joint is greater than 5mm, the depth of the ceramic tile joint shall be 1.5mm. 2. When cleaning the gaps of ceramic tiles, it must be ensured that the impurities in the gaps of ceramic tiles are cleaned, free of moisture, dust and particles. 3. When applying the sealant, you can try the effect first. Do not use the sealant with the front 30-40mm thickness. 4. During the construction of tile joint beautifying agent, pay attention to the time of joint pressing, and timely use the scraper to scrape the tile joint beautifying agent. 5. After the construction of tile sealant, the residual sealant on both sides of the tile gap should be cleaned in time, which can be wiped with a wet towel to prevent it from being difficult to clean behind. Use process of tile sealant 1. Before construction, prepare glue gun, brush, sponge, scraper, rag, shovel, sealant cone, masking paper, sealant and other tools, and determine whether to fill or half fill. 2. Use a sewing cone or blade to dig out a groove with a depth of less than 2mm from the tile gap, so that the sealant can be enough and the bonding plane is large enough to prevent it from falling off. 3. Use art knife and other tools to clean the sundries in the tile gap, and pay attention to the moderation to prevent damage to the gap. Then use a brush to clean the gap between the tiles, and then use a sponge to clean it. 4. Paste the seam paper at the edge of the tile gap about 1mm to avoid the spilled seam sealant polluting the tile. 5. Open the sealant hose and install it on the glue gun. When applying the sealant, ensure that the glue gun and the gap are at a 45 degree angle. The frequency of pressing the glue gun and the speed of moving the glue gun should be gentle, not too fast, and the uniform force can ensure the smoothness and balance of the sealant. 6. When applying the sealant, the pressing plate shall be used to compact the sealant gently in time. After pressing, the masking paper pasted on the tiles shall be torn off in time to prevent the masking agent on the masking paper from sticking together with the masking agent in the gap after curing. 7. After drying, use a blade to remove a small amount of residual seam sealant. Generally, the glue can be removed after 24 hours. In winter, the time needs to be extended to 48 hours.

How to choose and purchase high-quality sewing agents? With the development of the home decoration industry in recent years, the use of sewing agent products has become increasingly frequent and popular. However, the quality of sewing agents in the market is uneven. How to choose high-quality sewing agents? How to choose and purchase high-quality sewing agents? 1. No irritating smell: there is a irritating smell or a strong smell of sewing agent, indicating that the product has more harmful gases, which is more likely to affect your health. 2. Short curing time: the better the seam sealer, the shorter the curing time. If the required curing time is longer, it means that the curing agent is poor in quality and low in price. 3. After curing, the color is full and the finish is high: the beauty sewing product has good gloss after drying, which can reflect the advantages and disadvantages of the curing agent from the side. High quality seam sealants have natural gloss, high smoothness and good transparency after dry curing. 4. Check whether the joint sealant can resist yellowing after construction: generally speaking, the ordinary brand joint sealant does not have the ability to resist yellowing, and yellowing will occur after a year or two, affecting the overall beauty. After curing, the high-quality sealant is waterproof and mildew proof, not easy to fall off, and can effectively inhibit the growth of bacteria. When making beautiful sewing, what is the so-called full filling and half filling? Full filling means that the gap is filled with sealant; Half filling is to fill a part of the bottom of the seam of the tile with pointing agent first, and then fill the remaining surface with seam beauty agent. The full filling is more conventional. The advantage of using more sealant is that it is strong enough. However, if the product itself is inferior, it may collapse to a certain extent. Semi filling is because the joint sealant at the bottom is not the same material as the joint sealant at the top, and its firmness is not better than that of full filling. However, the advantage of semi filling is to save money. After all, the price of joint sealant is much more expensive than that of joint sealant, and the larger the sewing, the more expensive it will be. Also, there are few foremen who recommend you to fill in half. Because of the trouble, half filling requires the bricklayer to fill in and half pointing first. Then the bricklayer has to do some preparation work before the tiles are filled in and some cleaning work has to be done first. The master of sewing may suggest half filling. If he charges for materials and labor according to the unit price per square meter, half filling uses less materials, which is equivalent to earning more. Therefore, if the gap is relatively small, fill it directly. If the gap is half filled, it is not enough for the sealant to solidify; If the gap exceeds 4mm, half filling can be attempted from the perspective of budget. How about pointing and seaming zoning? This method is cost-effective and suitable for most family decoration. The beauty sewing of the whole house belongs to the local tyrant's game. In fact, it is not necessary. The advantage of beauty sewing is that it is more waterproof and mildew proof. In some places, there is no need to do beauty sewing in such places because there is no direct splash of water. How to match the color of tile and sealant? More popular, dark tiles are matched with light color caulking agent, which has a better sense of hierarchy and highlights the texture of tile paving. Conversely, light tiles are matched with dark color caulking agent. However, everyone feels different about aesthetics, just like it.

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, it uses a large capacity battery for power supply, completely eliminating 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. besides, HD80 is also equipped with a B-type USB interface that can be connected to an external computer for use as a USBDAC. Even more surprising, 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, HD80 is equipped with two 18650 mA lithium batteries for parallel power supply. I measured that the endurance time is at least 10 hours. DC power supply completely avoids the noise interference that may be introduced by 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. Below is a list of various input and output terminal blocks 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 the digital broadcast and front level, connects the E50 combined gall machine on the senior shift, The volume of the HD80 is fully turned on, and the volume is controlled by the camera. In fact, you don't have to worry about distortion when the HD80 output is too high, but you can also get a larger dynamic performance. Of course, you can also preset the volume of the power amplifier, and use the HD80 to control the volume of the audio system. The Soulnote entry-level S300 CD player was also auditioned, The HD80 is 50% cheaper than the S300. Is there a distance between the sound and the HD80? In fact, by comparing the CD of the same recording with the track grabbing file, The HD80 is obviously more stable and beautiful than the S300, and its sound field is wider. The HD80 is more balanced and transparent when replaying various styles of records, and its sound effect is better. This is an undisputed iron fact. When the symphony is replayed, HD80 can provide a delightful sound effect, which is more attractive from the following low-frequency parts with prominent potential and vivid knots. This unexpected result really surprised 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 scattered, HD80 has been 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. Drive the "grassroots headset", HD80 is really handy. It has outstanding performance in both dynamic and sound fields. Insert HE1000V2 into the high impedance interface, The driving force of HD80 is just enough. The dynamic is not as leisurely as driving "grass roots", but the overall sound quality is thicker, the color is more gorgeous and rich, 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 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.

Tiles are an indispensable building material in home decoration, so tile paving is a top priority, especially for wall tiles, which takes a lot of time. Under the condition of complete auxiliary materials and good base treatment, each worker can complete about 5 ㎡ in a day. Generally, it takes about a week to pave the bathroom and kitchen walls for home decoration. This is the traditional wet paving method, that is, cement mortar pasting. Is there a better way to shorten the construction period? This issue introduces a ceramic tile adhesive - Degao ceramic tile adhesive super strength (vitrified tile). Degao Ceramic Tile Glue is made of cement graded sand polymer admixture by modern technology. It is mainly used to paste ceramic tiles and stones of various specifications and materials. This product has excellent proportioning, simple and convenient paving process, saves time, and is relatively firm. The paving thickness is thinner, which saves space and reduces costs. Degao ceramic tile glue super strong vitrified tiles are packed in a valve bag with a specification of 20KG, which can be used to lay 3-4 ㎡ tiles. You can choose the appropriate quantity according to your actual paving area. Using scissors to open the Degao tile adhesive, we can see that the product is in the form of gray powder, similar to the color of cement, without smelling pungent odor. Mix Degao tile glue and cement mortar according to their respective proportions for standby. The former is fine and smooth without caking, while the latter presents caking and particles. Time saving: the construction is simple and fast. Next, the construction masters will demonstrate the construction of the wall on both sides prepared in advance, and paste 100 vitrified bricks on it to compare the speed and quality of the two construction. The cement mortar needs to wet the ceramic tile in advance. When paving, it needs to evenly plaster the cement mortar on the back of the ceramic tile, and then paste it on the wall, and press hard. This method is a great test of the master's construction technology. Compared with the paving process of cement mortar, the Yuhong waterproof wall Beili tile adhesive does not need to wet the wall and tiles in advance. When paving, only four steps of "one wiping, one scraping, one pasting, one pressing" can be followed. The 1 square meter wall was paved with Degao tile glue in 20 minutes by the master, but the wet paving method of cement mortar was not even half finished, and the brick fell off. It can be seen that the use of tile glue can save more than half of the time. Saving time is equivalent to saving labor, and thus saving costs. Convenience: The wall surface paved with Degao tile glue is beautiful and firm, neat and clean, with even gaps. If there is deviation, it can be adjusted in time, unlike the cement mortar, which needs to be knocked off and paved again once it is cured. Cost saving: For the walls with thinner paving thickness and Degao tile glue, there is almost no gap between the tiles and the wall, which can reduce the hollowing rate, while there are large gaps in the cement mortar, which is easy to appear hollowing if the master is not skilled. The paving thickness of Degao tile adhesive is only 5mm, while the paving thickness of traditional cement mortar is 10mm, which is twice as thin. This can save a lot of space for ordinary small houses. At the same time, the paving thickness also affects the amount of use, and the natural amount will be much less if it is thinner, thus saving costs. Degao tile adhesive is a time-saving, trouble saving and money saving adhesive. The test shows that the use of Degao tile glue to pave tiles is not only simple, but also can improve the construction process. The gaps of the tiles are even and beautiful, firm and safe without falling off. The paving thickness is only half of the traditional cement mortar, which can effectively save space and cost----------- I am a gorgeous dividing line -------- more wonderful home decoration design and layout, please pay attention to Qijia.com (WeChat: mall_jia). For more decoration inspiration and classic cases, please pay attention to Qijia Selection (WeChat: Qjiawan). (Editor in charge: Chen Tingting) Netizens' comments are not so clever. They are labor-saving but expensive. How much does the shop still need to give rebates to bricklayers per square meter? At such a fast speed, the masons earn two days' money a day by the square! I quickly changed my profession. It's better for Laozi to use easy clay. The wall is not vertical. Stick a wool??? Is it really so amazing that the company scrambled to use the decoration earlier, and you will die if you don't advertise on the practical post?? I don't know who still uses 100 * 100 bricks.... Try an 800 * 800!!!!! If the wall is uneven, how do you adjust it to 5mm???? Level first and then use your glue??? Take off your pants and fart!! The teacher can adjust the verticality with cement mortar!!!! It is also expensive that the beauty in use is the construction problem of skilled workers. It is recommended that you understand the Chenguang ceramic tile adhesive. The main thing for tiling is that there will be no hollowing and falling off. Chenguang ceramic tile adhesive can well avoid this problem. Good is good. Nowadays, developers do not need technicians to build houses. They rely on construction personnel to play their roles freely. The cement wall is vertical and the brick wall is vertical and flat at more than 1 to 2 cm. I think it is better to pave and paste cement mortar quickly. The ceramic tile adhesive requires too much on the wall surface, which may not be fast. It is normal for the wall tile to have some holes. It seems that Gaode Company has given you a lot of benefits! Toxic//@ watch me start in 5th gear: used
