    Core tip: in the mid-1990s, China published the gb5020794 national standard of technical code for roof engineering, which has made clear provisions on the quality requirements, construction methods and project acceptance of different types of waterproof coatings, which has played a positive role in the development of building waterproof coatings However, there is no mandatory standard for waterproof coating, and the market is chaotic, which needs to be further standardized In the decoration of kitchens and bathrooms, waterproofing is a necessary procedure, but in ten compulsory national standards, there is no limit standard for harmful substances of waterproof coating, so it should be further improved in the decoration of families Paint knowledge | precautions for wall paint

News: in the mid-1990s, China published the gb5020794 national standard of the technical code for roof engineering, which clearly stipulated the quality requirements, construction methods and project acceptance of different types of waterproof coatings, which played a positive role in the development of building waterproof coatings However, there is no mandatory standard for waterproof coating, and the market is chaotic, which needs to be further standardized In the decoration of kitchens and bathrooms, waterproof is a necessary procedure, but in ten compulsory national standards, there is no limit standard for harmful substances of waterproof coating, so the management should be further strengthened in the home decoration Some families found that the smell in the bathroom and kitchen was relatively large after decoration After detection by the testing center, it was mainly due to the pollution caused by waterproof coating, and this kind of pollution is not easy to remove At present, there are two kinds of waterproof materials in the market: one is polyurethane waterproof coating This kind of material is generally made of polyurethane and coal tar as raw materials The tar gas volatilized by it is toxic and difficult to remove, so it was banned from use in China in 2000 Polyurethane waterproof coating, which is still on sale, uses asphalt instead of coal tar as raw material However, when using this kind of coating, it is usually diluted with organic solvents such as toluene and xylene, which also contains toxicity The other is polymer cement-based waterproof coating It is made up of many kinds of waterborne polymers and high quality cement mixed with various additives The flexibility of polymer (resin) and the rigidity of cement are integrated, making it excellent in impermeability and stability It has the advantages of convenient construction, low comprehensive cost, short construction period, and non-toxic and environmental protection Therefore, polymer cement-based has become the leading role in the waterproof coating market Experts remind: some decoration companies and consumers mistakenly think that the waterproof treatment area of interior decoration is not very large After treatment, there are cement and ceramic tiles on it, which is not easy to cause pollution In fact, because the indoor waterproof layer generally needs to reach a certain thickness to have the corresponding waterproof function, so the use of materials is relatively large Once the waterproof coating containing pollutants is used in waterproof construction, indoor environmental pollution will be caused for a long time At present, in order to control the pollution of waterproof coating for interior decoration, it is necessary to control the materials used, and the non-toxic and environmental friendly waterproof coating should be the first choice At present, acrylate waterproof coating and tar free polyurethane waterproof material on the market are proved to be non-toxic, tasteless and environmentally friendly products Only the indoor floor treated with such waterproof coating can meet the requirements of indoor environmental protection Consumers should choose materials from reputable markets and choose qualified home decoration enterprises for construction In the process of decoration, as long as there is a constant use of water environment, such as kitchen, toilet, etc., should be treated with waterproof The use of waterproof coating is not only related to the overall effect of residential decoration, but also closely related to the health of residents Waterproof treatment is a "concealed project" in decoration, its effect will be presented after a long period of use If the waterproof coating contains toxicity, it will become the invisible killer in the home Therefore, the selection of waterproof materials can not be ignored Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
