Common knowledge of coating: pay more attention to the serious pollution of waterproof coating

Core tip: the use of waterproof coating must be careful Once the waterproof coating containing pollutants is used, it will cause indoor environmental pollution for a long time, and seriously harm people's health Therefore, we must do a good job in the selection of decoration materials 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 this kind of waterproof coating can meet the needs of the room Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: the use of waterproof paint must be careful Once the waterproof paint containing pollutants is used, indoor environmental pollution will be caused for a long time, and serious harm to people's health Therefore, we must do a good job in the selection of decoration materials 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 decoration of kitchens and bathrooms, waterproofing is a necessary procedure, but in the 10 compulsory national standards, there is no limit standard for harmful substances of waterproof coating, so the management should be further strengthened in family decoration The indoor environment monitoring center of China Interior Decoration Association has also received constant consultation from consumers Some families found that the smell in toilets and kitchens was relatively strong 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 Not long ago, the 8-minute poisoning incident of waterproof construction occurred in a hotel decoration site in Beijing, which resulted in one death and two injuries The poisoning was caused by the toxic gas released by the waterproof coating and diluent used by workers during the construction of waterproof coating on site According to the survivors, on the day of the incident, three constructors began to brush the waterproof coating at 8:20 in the morning One of the workers found a gas mask to work under the pool After about 8 minutes of work, three workers felt uncomfortable one after another, one fainted, and the other two fainted in the rescue process After 20 minutes, the poisoned personnel were sent to the hospital by the emergency center for rescue, and one of them arrived at the hospital The other two were rescued from danger The workers who had no previous history of liver disease after poisoning showed elevated transaminase, which has not improved significantly at present The poisoning of construction workers is caused by the toxic gas released from the raw materials used by the workers in the construction of waterproof coating on site The raw materials are polyurethane waterproof coating produced by a waterproof building materials company in Beijing that the workers bought on the market, and nitrodiluent produced by a paint factory in Beijing There is still a market for obsolete products At present, in the decoration engineering, it is necessary to carry out waterproof treatment for the places where water environment often exists, such as kitchen and toilet The indoor environmental monitoring center found that the polyurethane products containing tar are seriously polluted in the waterproof coating, which are generally made of coal tar or raw materials containing part of coal tar The volatile tar gas has Because the molecular weight of tar gas is relatively large, it is easy to deposit in the indoor environment where the air is not circulating, and excessive inhalation of tar gas in a short time can lead to rapid poisoning death; Another defect of this kind of waterproof coating is the use of organic solvent as diluent, which is mostly toluene, xylene and other toxic substances? Inhalation of tar gas and benzene in small doses for a long time can cause respiratory diseases, dizziness, nausea, and cancer At present, this kind of product has been designated as the elimination of building decoration materials by the relevant departments of the state However, due to the nonstandard decoration market management, some inferior products still have their own living space In particular, "decoration guerrillas" only focus on short-term interests, most of the constructors do not have basic health knowledge, and consumers do not have enough knowledge of waterproof, and they often introduce pollution into their homes without knowing it Environmental protection materials strictly check the new paint network experts remind that some decoration companies and consumers mistakenly think that the indoor decoration waterproof treatment area 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 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,
