Decoration is naturally inseparable from the main materials of woodworking materials: blockboard, integrated board, particleboard, density board, decorative panel and other plates. What is the role of these wood plates with different names in home decoration

Blockboard: it has good moisture-proof effect and cannot be painted directly. The middle of the blockboard is a core made of natural wood strips, with a thin veneer on both sides. It is one of the most important materials in decoration. It can be used for furniture, wooden doors, door jambs, heating hoods, curtain boxes, etc., with good waterproof performance. When selecting, look at its internal wood. It should not be too broken. Blockboard with a gap of about 3mm between the wood is appropriate. Because the exposed wood grain on the surface is not beautiful, it is rarely painted directly, and the decorative plywood is usually pasted. Furniture and other woodwork made with it need to go through two processes: gluing board and painting, and the cost is higher

integrated board: not easy to deform. This is a new kind of solid wood material, which is made of high-quality imported large-diameter logs, and is staggered like a finger. Due to different processes, this kind of board has superior environmental protection performance, which is 1/8 of the allowable formaldehyde content of blockboard. On the other hand, this kind of board made of solid wood such as American spruce can be directly colored and painted, which saves a process compared with Blockboard

the nail holding force of MDF is worse than that of particleboard. Particleboard is the main material of cabinet at present, which is made of natural wood after being crushed into granules and pressed into board. MDF is formed by pressing powdered sawdust, with good flatness but poor moisture resistance. In contrast, the nail holding force of density board is worse than that of particleboard. If the screws loosen after tightening, it is difficult to fix the density board because of its low strength, so it is rarely used as a cabinet

veneer plywood: easy and cheap. Multilayer board, also known as plywood and plywood, has different layers and different names. Its advantages and disadvantages mainly depend on raw materials. At present, veneer plywood is mainly used in home decoration, that is, very thin solid wood veneer has been pasted on the plywood in the factory. Veneer plywood is easy to use and cheap


first of all, it depends on whether it is environmentally friendly. According to regulations, the formaldehyde emission of indoor building materials must be less than or equal to 1.5 mg per liter. If it exceeds 5 mg per liter, it is substandard

secondly, it depends on the moisture content of wood. When the moisture content of wood is higher than the equilibrium moisture content of the environment, the wood will dry and contract, otherwise it will absorb moisture and expand. The main reason for wood cracking and deformation is that the moisture content is too high or too low

finally, don't just buy cheap. The materials sold at low prices are usually shoddy and formaldehyde seriously exceeding the standard. They should be purchased in the formal market, and it is best to buy branded materials
