At present, the main source of formaldehyde emission in home is man-made
board (ecological board, wood board, density board, multi-layer board,
particleboard, particle board, non solid wood floor and so on). Reducing
the use of wood-based panel can reduce the amount of formaldehyde
emission from the source.
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.
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
