What is the most concerning point about home decoration now? Environmental protection! Yes, today's home decoration is more important than other things, but environmental protection and safety issues, especially for the choice of wall paint, many decorated family homes They all have children and the elderly. If the decoration quality inspection fails, it will easily affect the health of the family.
In the decoration, we will brush the interface agent on the surface of the qualified painted wall before proceeding to the next step. The interface agent is actually equivalent to a kind of glue. Its main function is to remove the original wall or the floating dust and soil on the wall surface after shoveling the wall skin. Bond fastness. We use interface agents in the process of wall decoration. At present, most of the interface agents on the market are finished products based on polymer emulsions. This finished product has strong permeability and can fully infiltrate the surface of the base material. , Improve the adsorption of the base material, effectively prevent the occurrence of hollowing, cracking, delamination, and other problems when the surface material is bonded to the smooth wall. Interface agent is a general term, and the specific products are wall sealant, 108 glue, latex glue mixed with water, and other liquids.
Most decoration construction teams generally brush the interface agent on the original wall before proceeding to the next step. However, some companies have omitted this link for the sake of profit. It is difficult to judge by observation whether the interface agent has been brushed or not, so it is recommended that the owner be present when brushing the interface agent. In addition, the interface agent is a glue-like substance after all. To ensure its environmental protection, Xiaomeng recommends buying it in a regular building materials supermarket. If the interface agent is not environmentally friendly, your home is equivalent to painting a layer of poison gas cover on the entire wall, which will continuously emit harmful and carcinogenic formaldehyde and other harmful gases into the room within 3 to 15 years, seriously endangering the health of the family, and These are things you can't get rid of by opening windows for ventilation and are difficult to manage.
Another thing is to prevent some companies from buying counterfeit products for the sake of profit, and the owners don’t understand it and let it go! The current product counterfeiting methods are clever, and some even the anti-counterfeiting inquiry phone itself is fake, making it difficult for you to judge. It takes a variety of methods to judge the authenticity of the product, which is nothing but a loophole for many unscrupulous businessmen and some black-hearted companies!
Household pollution is concentrated within 1 meter above the surface. Those of us who have studied chemistry know that the average molecular weight of air is 29, and the molecular weight of the main polluting gases in the indoor environment is generally greater than this value. For example, formaldehyde (HCHO) is 30, ammonia ( NH3) is 31, benzene (C6H6) is 78, so its molecular density is greater than that of air. Therefore, most of the polluting gases produced by furniture, floors, paints, coatings, and other interior decoration materials will gather near the surface. According to experts, the height of the range is probably within 1 meter above the surface.
During the day, the indoor air will be more circulated with the frequent opening and closing of doors and windows. In addition, people usually walk upright on the ground or sit on chairs, so the height of the breathing zone at this time is generally between 1.2 meters and 1.7 meters. between. Therefore, it is difficult for people to feel the existence of pollution during the day, and it is easy to cause paralysis and carelessness; and at night, because the indoor air will be closed due to the closed doors and windows, and the height of the breathing belt will drop to about half a meter when people lie on the bed. People in the concentrated area and sleeping are the least sensitive, even if they are unknowingly harmed by air pollution, it is not easy to detect!
Due to the height and activity habits of infants and children, they are often in the range where the polluting gas is concentrated. In addition, according to the weight ratio, the air inhalation of quiet infants is twice that of adults, that is to say, the inhalation of polluted gases is also twice that of adults. In addition, infants and children have immature metabolic functions and immune systems and like to live in Crawling on the surface, sucking fingers, weak awareness of self-safety protection, difficulty to detect and express the harm of pollution, etc., have increased the seriousness of pollution to children's health, and made infants and children the main cause of pollution. object.
Therefore, it is very important to check the purchase channels of products that are more important to environmental protection and to check the authenticity of the products, so we must make good environmental protection checks when decorating. Not only the strictness of wall decoration materials but also the decoration building materials, etc., must be checked and carefully screened.
