Where does formaldehyde come from
A large part of it comes from the cheap glue inside the wood-based
panel, urea formaldehyde resin. Formaldehyde + urea = urea formaldehyde
resin, formaldehyde which is not completely dissolved will be free in
the plate and then slowly released.
Other building materials such as: paint, plastic products, adhesives may
also contain formaldehyde, but compared with the release of man-made
panels, they are not worth mentioning.
在木材加工业各种人造板材中，脲醛树脂和它的改性产品占到了胶粘剂使用量的九成。在我国有毒化学品优先控制名单中名列第橡胶托辊 槽型托辊 皮带托辊 平行托辊 保定搬家 保定搬家电话 保定搬家公司 保定搬家 铜鼎 铜狮子二（第一是二恶英）。
In wood processing industry, urea formaldehyde resin and its modified
products account for 90% of the adhesive used. It ranks second in the
priority control list of toxic chemicals in China (the first is dioxin).
Do you have more environmentally friendly glue
Yes, MDI glue, melamine formaldehyde resin, etc.
But because of its low cost, simple process and good viscosity. Urea
formaldehyde resin is very stable. Although there are many more
environmentally friendly and better used alternatives, their costs are
not competitive enough
