密度板包括内部纤维污染，以及用于家具制造的各种纤维板和刨花板。它也被称为废板。它是一块木屑、小直径木材、木屑等，它被切割成一定的标准。由橡胶、固化剂、防水剂等人造板制成，在一定的温度和压力下压制而成。此外，还使用了一些竹子、稻草、甘蔗渣和其他纤维。这种人造板叫三聚氰胺板，是用三聚氰胺贴面制成的。据估计，每个云母生产MDF所需要的含脲醛树脂粘结剂的甲醛量一般为200~250kg。
Density board includes internal fiber pollution, as well as various fiberboard and particleboard used in furniture manufacturing. It is also known as the waste plate. It is a piece of sawdust, small diameter wood, sawdust, etc. it is cut into a certain standard. It is made of rubber, curing agent, waterproof agent and other wood-based panels, which are pressed under certain temperature and pressure. In addition, some bamboo, straw, bagasse and other fibers were used. This kind of artificial board is called melamine board, which is made of melamine veneer. It is estimated that the formaldehyde content of urea formaldehyde resin binder for MDF production of each mica is generally 200-250kg.
细木工板通常被称为大芯板。它是一种由脲醛树脂粘合剂制成的人造板，用来把上、下胶合板和一小块中间的木头固定在一起。是由天然木条和双面粘贴是一个非常薄的贴面核心。大芯板是装饰中更重要的材料之一。
Joinery board is usually called big core board. It is a kind of wood-based panel made of urea formaldehyde resin adhesive, which is used to fix the upper and lower plywood together with a small piece of wood in the middle. The center is made of natural wood and double-sided paste is a very thin veneer core. Big core board is one of the most important materials in decoration.
细木工板是我国城乡居民用于室内装饰的装饰材料。可用于家具、木门、门窗、暖气罩、窗帘盒等。其防水防潮功能优于刨花板和中密度纤维板。然而，由于使用了脲醛树脂粘结剂，装饰装修所形成的室内环境形成了潜在的甲醛污染。
Joinery board is a kind of decorative material used for interior decoration by urban and rural residents in China. It can be used for furniture, wooden doors, doors and windows, heating covers, curtain boxes, etc. Its waterproof and moisture-proof function is better than particleboard and MDF. However, due to the use of urea formaldehyde resin binder, the indoor environment formed by decoration has formed potential formaldehyde pollution.
胶合板通过蒸汽和软化沿年轮将木材切割成大块，并通过干燥、挤压、上胶、成型、热压和锯切来形成人造板。胶合板木屑的层数应该是奇数，通常为3到13层，相邻的木屑纤维粘在一起时应该是直的。胶合板主要用于实木材料、密度板、细木工板和指板的装饰和家具制造。主要生产工艺为人造板，用脲醛树脂胶粘接三、五、七、九层木皮。
Plywood is cut into large blocks along the rings by steam and softening, and wood-based panels are formed by drying, extruding, gluing, shaping, hot pressing and sawing. The number of layers of plywood sawdust should be odd, usually 3 to 13 layers, and the adjacent sawdust fibers should be straight when glued together. Plywood is mainly used for solid wood materials, density board, joinery board and finger board decoration and furniture manufacturing. The main production process is wood-based panel, which uses urea formaldehyde resin adhesive to bond three, five, seven and nine layers of veneer.
