家装中甲醛污染的来源有哪些？一般残留多长时间？
What are the sources of formaldehyde pollution in home decoration? How long does it last?
室内空气中甲醛主要来源于木制家具、化纤塑料制品、涂料和粘合剂。例如我们木制板材中的人造板，绝缘材料、地毯、壁纸、防水材料以及尿醛胶等。其中人造板就是将废木材破碎成为纤维以后，再加进粘合剂制造而成，而普通的粘合剂中常含有一定的甲醛。
Formaldehyde in indoor air mainly comes from wooden furniture, chemical fiber plastic products, coatings and adhesives. For example, our wood-based panels, insulation materials, carpets, wallpaper, waterproof materials and urea formaldehyde glue, etc. Among them, wood-based panels are made by crushing waste wood into fibers and then adding adhesives. Ordinary adhesives often contain certain formaldehyde.
根据甲醛来源不同，甲醛残留时间长短不一，一般来说，涂料和化纤塑料制品的甲醛多附着在我们的装修物的表面，挥发起来相对容易，甲醛粪池模具 路缘石模具 唐山通风管道 塑钢电缆挂钩 钢纤维 钢制拍门 植绒机 铜雕佛像残留时间就较短，一般半年或者过1个夏天基本上就没有残留了；而人造板中的甲醛，由于深藏在我们的密致的板材当中，短则3年，长的可以到8年才能挥发干净
According to the different sources of formaldehyde, formaldehyde residue time is different. Generally speaking, the formaldehyde of coatings and chemical fiber plastic products is more attached to the surface of our decoration, volatilization is relatively easy, formaldehyde residual time is relatively short, generally half a year or after a summer basically no residue; and the formaldehyde in wood-based panels, due to deep hidden in our dense board, short It takes three years, and eight years for long ones to volatilize
