Anonymous users2024-01-24Indoor formaldehyde pollution sources are divided into long-term formaldehyde pollution sources and short-term formaldehyde pollution sources, short-term formaldehyde pollution sources include wall paint, wallpaper, curtains, etc., which will volatilize in about 3-6 months, but pay attention to open windows for ventilation; The long-term source of formaldehyde pollution is mainly the decorative wood used in decoration and the wood-based panels used in furniture, a large number of adhesives are used in the production process of wood-based panels, and the adhesives will decompose and volatilize a large amount of free formaldehyde when they are damp and heated, and the release cycle is about 3-15 years, so this is why formaldehyde will generally exceed the standard in summer or after heating.

Anonymous users2024-01-23Formaldehyde is mainly volatilized by the glue of furniture panels, and the mirror does not contain formaldehyde.
Both, furniture is composed of boards, glue substances, and paint, which are harmful substances containing formaldehyde and benzene. Therefore, formaldehyde, benzene, etc. should not be emitted, and their release will take up to more than ten years, so it is very important to treat formaldehyde. >>>More
Formaldehyde exceeds the standard because decoration materials and furniture materials contain formaldehyde, because formaldehyde is an indispensable main component of woodworking boards, paints, and latex paints.
It should be a mixture of paint and glue, the furniture you buy should be panel furniture, veneer, hot melt adhesive will need to be used in the process of veneering, relatively large, good companies will use better, environmentally friendly hot melt adhesive, but small enterprises will choose some less good quality glue. There is also related to the base material they choose, that is, the board, the board used in the furniture is crushed, glued, molded, considering the durability of the board, will choose phenolic glue and urea-formaldehyde glue with good adhesion, but they will volatilize toxic gases, and the panel furniture with poor quality will always volatilize, so what you feel now is normal.
Generally speaking, government departments do spot checks, and they don't do the census, and the manpower required for the census is too great. However, there is a common sense that the furniture from the furniture factory contains formaldehyde, even if it is the original wood, it also contains a small amount of formaldehyde synthesized by organisms. Therefore, there will also be formaldehyde in log furniture, but the content is very low and does not harm human health.
You should be able to know the smell of wood, formaldehyde is a very pungent smell, if formaldehyde is first very pungent, and then there are eyes (tears) this is typical.
