Main sources of formaldehyde pollution in new house decoration
Time：2019-04-30 Editor：恩特科技
Formaldehyde pollution caused by building decorative materials and other reasons are:
1. Coatings, chemical fibre carpets, cosmetics and other products using formaldehyde as preservative;
2. Decoration materials and new combination furniture are the main sources of formaldehyde pollution. Formaldehyde is released when the adhesives of plywood, large core board, medium fibre board and particleboard (particleboard) in decoration materials and furniture are heated and deliquescent, which is the main source of formaldehyde emission in the room.
3. Indoor smoking. Each smoke contains 20-88ug formaldehyde and has a synergistic effect on carcinogenesis.
5. Because formaldehyde has strong adhesiveness and can strengthen the hardness, insect-proof and anti-corrosion ability of the board, urea-formaldehyde resin, which is mainly composed of formaldehyde, is used in all kinds of particleboard, medium density fiberboard, large core board and plywood on the market at present, so formaldehyde will inevitably be contained. Perhaps many consumers will say, I use environmental protection board, how can formaldehyde exceed the standard? In fact, environmental protection products are not.
Represents no formaldehyde, the detected formaldehyde content in indoor air is the superposition of all materials releasing formaldehyde. Therefore, in the process of decoration, even environmental protection products can not be overused.
6. Wallpaper's glue
"All the materials I use are environmentally friendly coatings, how can formaldehyde be found?" "It's empty inside, how can formaldehyde be detected?"
Formaldehyde is hidden in wallpaper if there is no use of a large number of boards. Usually, before applying paint, a layer of putty should be scraped on the wall. Putty is mixed with talc powder and glue, which is also the main source of formaldehyde. Wall with wallpaper will release more formaldehyde. For convenience, construction workers may brush a layer of paint on the wall first. Paint is also the source of formaldehyde.
One of. The glue between the wall and wallpaper, because of the impermeability of wallpaper and other reasons, is difficult to emit, becoming another source of pollution;
At present, the home on the market has solid wood and sheet metal. Relatively speaking, solid wood is more environmentally friendly than board, but not that solid wood must be environmentally friendly, and board must not be environmentally friendly. Furniture from processing to transportation, delivery time is relatively short, furniture inevitably become the main culprit of indoor pollution.
In view of the problem of wallpaper glue, we recommend the use of removable brick wallpaper, which is a new type of convenient home decoration wallpaper, we use hot-melt resin glue, no formaldehyde, green environmental protection, and through product safety testing, just opened the packaging bags and the number of products, the backing paper will smell slightly, harmless to human body. A PE isolation film is also coated on the removable brick wallpaper of Korean technology.
Environmental friendly hot melt adhesive is a solvent-free and volatile-free thermoplastic adhesive. It is a kind of plastic adhesives. Its physical state changes with temperature in a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and it belongs to environmental protection chemical products. Because the product itself is solid, easy to package, transport, storage, solvent-free, pollution-free, non-toxic; as well as simple production process, high added value, high bonding strength, fast and other advantages, it is favored. All the raw materials used meet the international environmental protection requirements. It will not pollute the environment in the process of production and use, and will not cause harm to health. Environmental friendly hot melt adhesives have passed many international environmental certifications. Environmental friendly hot melt adhesives have been widely used in removable brick wallpaper, medical, health, food, household, automotive, packaging, electronics, footwear and other industries.
