各种人造板材以及装修过程中使用的胶黏剂是甲醛的主要来源。由于甲醛具有较强的黏合性，目前生产人造板使用的胶黏剂是以甲醛为主要成分的脲醛树脂。因此各种人造板材以及用人造板材制造的家具、地板中均有一定量的甲醛残留。此外，很多装修材料或者在装修过程需要使用胶黏剂，例如木地板在装修过程中需要用胶黏剂，地毯在制造中所使用的背衬材料是采用胶结力很强的丁苯胶乳、天然乳胶等水溶性橡胶做胶黏剂黏合而成的，壁纸胶黏剂同样采用了大量的挥发性有机溶剂，这些胶黏剂在使用时会挥发出甲醛等污染物。
The main source of formaldehyde is all kinds of man-made boards and adhesives used in decoration. Due to the strong adhesion of formaldehyde, the adhesive used in the production of wood-based panels is urea formaldehyde resin with formaldehyde as the main component. Therefore, there are a certain amount of formaldehyde residues in all kinds of artificial boards, furniture and floors made of artificial boards. In addition, many decoration materials or in the decoration process need to use adhesives, such as wood flooring in the decoration process need to use adhesives, carpet used in the manufacturing of backing materials is made of water-soluble rubber such as styrene butadiene latex, natural latex and so on with strong adhesive force, wallpaper adhesives also use a large number of volatile organic solvents, these adhesives Formaldehyde and other pollutants will be volatilized during use.
由于装饰和装修材料中普遍含有甲醛，我国对很多建筑材料和室内物品甲醛的释放量制定了标准限值。例如，《室内装饰装修材料定网站建设  伺服液位仪  防撞墙模具 唐山护栏  钢纤维 天津除甲醛  保定铝型材人造板及其制品中甲醛释放限量》规定，中高密度纤维板及其制品中甲醛释放量需低于9mg/100g，胶合板、细木工板等需低于1.5mg/100g。
Because formaldehyde is generally contained in decoration and decoration materials, China has established standard limits for formaldehyde emission of many building materials and indoor articles. For example, the formaldehyde emission limit of wood-based panel and its products for interior decoration materials stipulates that the formaldehyde emission of medium and high density fiberboard and its products shall be less than 9mg / 100g, and that of plywood and joinery board shall be less than 1.5mg/100g.
