How does the water purifier work?

How does the water purifier work? Water purifier, also called water purifier, is a water treatment equipment that deeply filters and purifies water according to the requirements of water use. Generally speaking, the water purifier refers to a small purifier for household use. How does the water purifier work? Working principle of water purifier Level 1: PP cotton: remove all kinds of visible objects/dust and impurities in tap water. The second and third stages: pre activated carbon: the third stage of some low distribution water purifiers is also PP cotton, and the carbon removes chlorine and organic impurities. It can also absorb the odor, color and smell produced by organic compounds in water. Level 4: ultrafiltration or reverse osmosis membrane: the membrane can remove bacteria, viruses, spores and other substances in the water. Level 5: Post activated carbon device: further improve the taste and remove odor. Most water purifiers adopt the progressive structure mode of screen blocking filtration principle, which is made of multi-stage filter elements connected in series from the beginning to the end. The filter elements are arranged in order from low to high precision, so as to realize the multi-stage filter elements to share and intercept the dirt, thus reducing the filter element blockage, manual blowdown, removal and cleaning times, and prolonging the cycle of filter element replacement.

Are marble tiles expensive? What are the advantages?

Are marble tiles expensive? The texture of each marble tile is unique, especially the combination of these patterns with different colors and sizes is very fashionable, which is why many owners choose to use marble tiles for decoration. Is marble tile expensive? What are the advantages? Are marble tiles expensive? Marble tile stone includes cultural stone, marble, granite, etc. Cultural stone also includes natural cultural stone and artificial cultural stone. The prices of various stones vary greatly due to their different colors, manufacturing processes and textures. Marble price culture stone has various shapes and different colors, and is mostly used for indoor partial decoration, such as the decoration of indoor TV wall, the convex shape around the iron heating hood, or the ground treatment in the courtyard. The decoration effect is close to nature, reflecting the simple and unsophisticated decoration style. The artificial cultural stone is made of natural cultural stone through reprocessing. It is lighter, non-toxic, mildew free, and easy to install. It is suitable for local wall treatment to reduce the load-bearing capacity of the wall. The price is also more expensive than the natural cultural stone. The price of brands produced by joint ventures is generally more than 300 yuan/box. If they are imported brands, the price will be higher, It can reach about 1000 yuan/box. The price of natural cultural stone is much cheaper, generally around 120 yuan to 130 yuan/square meter. Consumers can make targeted purchases according to their economic capacity and needs. Advantages of marble tiles: 1. Beautiful and generous. Maybe the first thing that attracts you is the beautiful shape of marble floor tiles. Few building materials are as beautiful as marble. There are dozens of different varieties of marble. The choice of color ranges from black to pink to white, and even dark green with white texture (this is the most expensive kind of marble). Marble can complement many different decorative styles, from classical to ultra modern. 2. Strength improvement: after marble is compounded with ceramic tile, granite, aluminum honeycomb board, its bending, bending and shear strength is significantly improved, greatly reducing the damage rate during transportation, installation and use. 3. Long life, marble's life is beyond imagination, and it has durability. Marble is one of the oldest building materials, especially favored by Greeks and Romans. Their special marble works still exist today. If the marble is correctly installed in a suitable area, for example, in a floor that is not often used, you may not need to replace the marble in your life. 4. Improvement of anti pollution ability: During the installation or later use of ordinary marble raw boards (full body boards), if cement is used for wet pasting, it is very likely that six months or one year later, various discoloration and stains will appear on the marble surface, which is very difficult to remove. Because the bottom plate of the composite board is harder and denser, and there is also a thin adhesive layer, this situation can be avoided.

Is there formaldehyde in latex paint? How harmful is it?

Is there formaldehyde in latex paint? Formaldehyde is a colorless, dazzling, pungent and throat piercing substance. In many building materials, there is some formaldehyde. Latex paint is now a material that many families will use in decoration. Is there formaldehyde in latex paint? How harmful is it? Is there formaldehyde in latex paint? Latex paint contains a certain amount of formaldehyde, because formaldehyde itself has sterilization and anti-corrosion effects, but it does not mean that formaldehyde is toxic. The formaldehyde poisoning we often hear is caused by the high formaldehyde content of latex paint. Formaldehyde content of formal latex paint specially used for wall decoration is generally controlled within the range of national standards. In addition, emulsion paint belongs to water dispersible paint, and its film performance is better than solvent based paint. The toxicity of traditional organic solvents is basically solved by latex paint. However, it should be noted that some latex paints with poor quality will still emit a large amount of organic pollutants when used, so special attention should be paid when purchasing. Benzene series should be added to the production raw materials of any paint that can be used for decoration within a few days after painting the emulsion paint. For example, formaldehyde content must be in the glue. There is no real formaldehyde free adhesive or formaldehyde free product on the market for the time being, but it is relatively safer and environmentally friendly. It is recommended to buy regular latex paint brands, such as Sankeshu, which belong to the first tier brand of latex paint and are relatively more environmentally friendly and safe. However, it cannot be ruled out that some black heart manufacturers will not be standardized in the manufacture of latex paint, which will cause the content of formaldehyde, benzene and other substances to exceed the standard. So, how many days can I stay after painting emulsion paint? It is recommended to keep the room ventilated after painting, at least for more than a month, and it will not cause harm to human body if you enter again. If there are elderly, children and pregnant women in the family, try to ventilate for more than 2-3 months. When buying latex paint, friends should try to choose environmentally friendly latex paint products. When buying latex paint, don't be greedy for cheap. You must buy products of well-known brands, so as to ensure the safety of yourself and your family.

Does art paint have formaldehyde? Is there any physical harm?

Does art paint have formaldehyde? Now people have a strong awareness of environmental protection. When they decorate, they are most worried about formaldehyde, which is unsafe, unsanitary, and also volatilizes toxic and harmful gases. Now art coatings are favored by many families. Is there formaldehyde in art coatings? How harmful is it? Does art paint have formaldehyde? At the production stage of artistic coatings, the quality of raw materials has been strictly controlled, and the entire production and processing process has been standardized. No other harmful chemicals have been added in the process, so the materials themselves will not volatilize toxic and harmful gases. In addition, during construction, artistic coatings can be adsorbed on the wall without adding chemical glue, and there will be no formaldehyde generated by chemical glue, Therefore, decoration of the room with artistic paint will not pose any threat to human health and will not cause any harm to the children at home. Generally, you can stay at ease two or three days after decoration. What toxic and harmful gases will be left after the house is decorated, and what are their respective hazards? After decoration, the common harmful gases in the room are formaldehyde, benzene, ammonia, etc. Among them, formaldehyde has a very bad effect on human respiratory tract, eyes, liver and lungs; Benzene is recognized as a carcinogen, which can cause poisoning symptoms and damage human nervous system and hematopoietic system; Excessive ammonia inhalation will lead to emphysema and bronchospasm. When decorating, people pay special attention to whether the formaldehyde content exceeds the standard. After the room is decorated, there will be formaldehyde more or less, but it is hard to smell. Even if it exceeds the indoor formaldehyde content standard, it may not be impossible to smell it. If we smell formaldehyde indoors, the formaldehyde content will seriously exceed the standard. Which materials will produce toxic and harmful gases? Many materials for interior decoration will volatilize the above gases. Some inferior materials have the above gases themselves, and some materials are of good quality. However, during the construction process, glue is required for bonding, and the glue will volatilize harmful gases such as formaldehyde. Is there any way to prevent or eliminate these toxic and harmful gases? Ventilation naturally emits, and harmful gases in the purified air can also be chemically removed. A special air purification team is invited to remove formaldehyde and other gases through professional means. Of course, the best thing is to check the product quality from the source. Before decoration, choose low formaldehyde or formaldehyde free materials to control formaldehyde below the standard line.

Are solid wood doors expensive? How to choose the right solid wood door?

Are solid wood doors expensive? When decorating, more and more family doors tend to be solid wood doors. Solid wood doors are not only good in material, but also durable, which has become the priority choice of many friends. Is the price of solid wood doors high? How to choose the right solid wood door? Are solid wood doors expensive? 1. First, paint free solid wood doors. At present, paint free solid wood doors are the most popular kind of solid wood doors. The price of such doors is about 450-600 yuan. If better brands, accessories and styles are required, the price is about 800-1000 yuan. If paint free solid wood doors are used in bedrooms and study rooms, it is enough. 2. The baking varnish solid wood door is also the baking varnish solid wood door and the paint free solid wood door. The baking varnish solid wood door has a complex process and many production processes, so the price is more expensive than the paint free solid wood door. The price is about 1500-2000 yuan. Although it is expensive, the baking varnish solid wood door is relatively durable, which is one of the main reasons why people like it. 3. The solid wood composite door is not made of 100% solid wood materials, but supplemented with other materials. However, the price is not low. The price is about 1300-1800 yuan. The solid wood composite door attaches great importance to materials. How to choose and buy solid wood doors 1. First, the quality of wood doors. To make the wood doors durable and not easy to deform, it is necessary to use the strictly dried solid wood keel material. The internal filling material structure is reasonable. The country divides the appearance indicators of wood doors into three standards: high, medium and general. High quality wooden doors need to be made by hot pressing process. Solid wood edge banding machine is used for mechanical edge banding, and sanding machine is used for leveling and sanding to ensure flatness, firmness and beauty. The quality of the wooden door manufacturing process will directly affect the service life of the wooden door. Generally speaking, after the wooden door has been used for a period of time, it is more likely to have deformation, cracks and other problems, which will reduce the sound insulation effect. Therefore, the wooden door can have a better effect through the manufacturing process. The wooden door has low water content, is not easy to deform and crack. The sound insulation effect of wooden doors depends on materials and processing details. The sound insulation effect of doors is achieved by reducing air flow. Therefore, the higher the density of doors, the heavier the weight, and the better the sound insulation effect. 2. In addition to the creation process of the wooden door itself, the material of hardware will also affect the service life of the wooden door. The hinge is a kind of hardware that connects the door and the door frame. The high-quality hinge has anti-corrosion performance and transmission, so that the hinge is evenly stressed and will not be damaged due to the weight of the door.

Is the performance of water-based paint good? Is it corrosive?

Is the performance of water-based paint good? Everyone knows something about water-based paint, especially those who have decorated or are in the process of decoration. Now water-based paint has become the choice of many users. Is the performance of water-based paint good? Is it corrosive? Is the performance of water-based paint good? (1) Poor dispersion of pigments. Waterborne paint belongs to polymer dispersion system, and pigment dispersion is not very good, so measures must be taken to improve it. (2) The stability of dispersed particles is poor. Dissolved molecules are stable to shear force, heat, pH, etc., while dispersed particles are unstable, so stability measures should be taken for the dispersion system. Dispersed particles will be damaged after being subjected to shear force, so it is necessary to consider avoiding the role of shear force in the process of manufacturing and transporting water-based paint. Dispersed particles are very sensitive to pH value, and acid particles will be formed when acid substances are mixed into the paint, thus causing gelation and destruction of water-based paint. In addition, dispersed particles of water-based paint will also be damaged after freezing during transportation. (3) High surface tension. The surface tension of water is large (see Table 2), so the surface tension of water-based paint is also large. Management should be strengthened during the construction process, otherwise the following defects and film defects are likely to occur during coating: a. easy sagging; b. Poor flattening; c. It is easy to produce shrinkage cavity and pinhole; d. It is not easy to stretch into the small cracks on the surface of the coated object. (4) The evaporation heat and heat capacity are high and are greatly affected by temperature and humidity. The high evaporation heat and heat capacity of water (see Table 2) slow the evaporation of water in water-based paint. 50% of the total amount of solvent in solvent based paint evaporates during spray atomization, while only 25% for water-based paint. Slow evaporation of water is easy to cause sagging during painting, and makes painting efficiency worse. Therefore, an intermediate heating zone is required to volatilize water from the water-based primer coating. Before spraying varnish, 90% of water must be removed from the water-based primer coating (to prevent boiling water from volatilizing through the varnish during final baking) to obtain the best paint film appearance, so as to prevent the water-based primer from being re dissolved by the varnish. The evaporation rate of water is closely related to the relative humidity. When the relative humidity is high, the evaporation rate of water is very low. Therefore, the relative humidity and temperature of the spray booth must be controlled within a certain range to ensure that an appropriate amount of water is volatilized during the spray atomization process, and that water and organic solvents are properly balanced in the film. This proper balance is very important, which can make the paint have proper surface tension to wet the sprayed surface (see Table 2). (5) Good conductivity. The dielectric constant of water is large (see Table 2), so the conductivity of water-based paint is good. Generally, the resistance of water-based paint is less than 0.1M Ω), while solvent based paint has a certain resistance: 0.5~20M Ω. Waterborne paint has good conductivity, and there are special requirements when electrostatic spraying is used. (6) High corrosivity. The water-based paint contains a lot of water, so it is corrosive to containers, transmission pipelines, paint booth and other parts vulnerable to moisture. Stainless steel or plastic products are required. (7) Rheological behavior. When the viscosity of fluid decreases with the increase of shear rate, it is called pseudoplastic fluid. The rheological behavior of pseudoplastic fluid is related to its rheological path, that is, it is time dependent, so it is called thixotropic fluid. Based on the characteristics of water-based paint, the viscosity value measured by flow cup does not have reproducibility, and the complete rheological curve of data points including low shear rate and high shear rate measured by rotary viscometer can give the complete characteristics of rheological behavior of water-based paint.
