The preferred material for cabinets is particleboard.
Particleboard is made of high-quality wood or small-diameter wood through cutting, gluing and pressing. The middle layer of particleboard is made of long wood fibers, and the two sides are made of fine wood fibers, which are pressed into plates by large machines. Because particleboard is superior to MDF in bending resistance and nail holding power, and has less glue content and low formaldehyde content, it is the first choice for cabinet boxes at present.
There are three kinds of cabinets: E0 grade moisture-proof particleboard, E 1 grade moisture-proof particleboard, ordinary moisture-proof particleboard and ordinary double-sided particleboard. Imported particleboard: At present, almost all cabinet factories in Europe and America use particleboard, and the formaldehyde content of imported particleboard is low. It has reached the European E- 1 environmental protection standard. The molecular structure is compact and the bending strength is high. More than 50% of the products are added with green moisture-proof agents. Even if the particleboard is soaked in water, the expansion rate will not exceed 8%.
Domestic particleboard: Due to the adoption of a complete set of imported equipment, several domestic manufacturers can also produce products with tight molecular structure and high bending strength. Generally speaking, if the surface decoration is imported from Germany, most of them are produced by big factories and used in high-end furniture, buyers and suppliers pay more attention to market reputation, so there are fewer problems and meet the national environmental protection standards. Particleboard produced by small domestic factories: Small domestic factories can only produce some ordinary white cardboard and beech diamond plate. Due to the backward equipment and production technology, the bearing capacity, bending resistance and deformation strength of the produced board are poor, and the furniture made is easy to loosen after fastening, and the formaldehyde content is extremely high, which is dozens of times higher than the national standard, which is extremely harmful to human health. It is the quality of this kind of board that tarnishes the reputation of particleboard and leads consumers to mistakenly think that the quality of particleboard is low. E 1 grade moisture-proof board: the base material is E 1 grade particleboard, which conforms to the European environmental protection E 1 grade standard, and is added with moisture-proof powder and pasted with imported melamine on both sides, with a thick surface texture.
Features: Strong moisture-proof and corrosion resistance, low formaldehyde content, and difficult deformation of plates. Ordinary moisture-proof board: the base material is ordinary particleboard or density board, which meets the national (GB) first-class standard, without moisture-proof powder, with imported melamine stuck on both sides and thick surface texture. Features: Strong moisture-proof performance, low formaldehyde content, and the plate is not easy to deform. Low-grade double panel: the base material is the lowest grade particleboard or density board, which has not been treated with moisture-proof and anti-corrosion, and is pasted with domestic melamine on both sides, with thin surface texture. Features: high formaldehyde content, easy deformation of plate, low density of base material, no nails, easy nail removal after cabinet completion, short service life.
It is best to use brand double decorative board, also called melamine board, which is much better than joinery board and does not need paint. The best melamine board made in China is E0 grade board of Lushuihe, Jilin Forest Industry. It must be certified as genuine when purchasing. The best imported particleboard is imported from Europe.
Iger board has a high level of environmental protection, and its nail grip, moisture resistance and bending resistance are better than those of domestic particleboard.
