When we talk about home improvement and furniture, the threat of formaldehyde is often mentioned. This colorless gas is hidden in the wood-based panels, silently eroding our health. For adults, formaldehyde may cause irritation of the eyes, nose and throat, and can even cause cancer.
For children, formaldehyde is more harmful. Because their bodies are smaller and their immune systems are weaker, they are more likely to inhale formaldehyde and be harmed by it than adults. Formaldehyde not only has an impact on children's growth and development, but can also cause various respiratory diseases, even leukemia. Therefore, it is particularly important to choose low or formaldehyde-free home decoration materials, especially for families with young children, which is more of a responsibility and obligation.
Formaldehyde ** accounts for a heavier proportion of the board when decorating the home, after all, all spaces in the house are inevitably made of cabinets, wooden doors or floors, so the environmental protection of the board has attracted much attention.
Wood-based panels are boards or molded products made from wood or other non-wood plants that are glued together with adhesives. The most commonly used adhesive or glue is urea-formaldehyde glue. This adhesive releases a large amount of formaldehyde during the curing processAt present, most of the man-made boards on the market are bonded with urea-formaldehyde glue, and of course, there are also so-called environmentally friendly glue MDI glue or protein glue for wood board gluing.
So are these so-called environmentally friendly glues really environmentally friendly?First, let's take a look at MDI glue. MDI glue is a polyurethane glue with isocyanate as the main raw material, although there is no formaldehyde in the raw material of MDI formaldehyde-free glue, it contains benzene, and benzene is classified as a class of carcinogens, and the threat to health is not less than formaldehyde. In addition, many products made of MDI adhesive still add a small amount of urea-formaldehyde glue containing formaldehyde to the surface in order to prevent cracking of the board and facilitate the lamination of the finish.
Second, let's take a look at the protein gelatin. Protein glue is a natural adhesive taken from automatic plants, which is known as a real environmentally friendly glue. However, although protein glue is non-toxic and harmless, its adhesive strength and water resistance are poor, and it cannot be used to bond boards alone, and must be used in conjunction with other glues, including formaldehyde glues such as urea-formaldehyde resin glue.
And one thing worth noting:"Formaldehyde-free core board"It is not the same as formaldehyde-free veneer. Even if the coreboard made with these popular eco-friendly adhesives on the market meets the environmental standards, it does not necessarily mean that the finished finish is environmentally friendly. The realization of formaldehyde-free technology of impregnated decorative paper is still difficult at home and abroad, and formaldehyde is often used in impregnated paper, and many of them can not even meet the requirements of the national standard E1 level.
Although we can see that MDI adhesives and protein adhesives on the market have advantages in some aspects, they also have many problems and shortcomings, and cannot meet our expectations of truly environmentally friendly products. Is there a better choice for consumers with high environmental requirements?
We have reason to believe that a new type of highly environmentally friendly wood-based panel called Rekang board may be the most ideal choice for us in the pursuit of high environmental protection home.
Such a high environmental protection board is suitable for home decoration with high environmental protection requirements of the family's choice, the choice of heat board, is the choice of healthy and environmentally friendly home.
