The decoration is naturally inseparable from the main materials of woodworking materials: blockboard, integrated board, particle board, MDF, veneer and other various plates. What are the functions of these different names of wood boards in the home decoration? The following are experts The explanation we made for us:
Blockboard: good moisture resistance, can not be directly painted
In the middle of the blockboard is a core made of natural wood strips, with thin veneers on both sides, which is one of the most important materials in the decoration. It can be used for furniture and wooden doors and door covers, heating covers, curtain boxes, etc., and its waterproof performance is good. When selecting, look at its internal wood, it should not be too broken, and the gap between the woods is about 3mm. Due to the unsightly appearance of the wood grain on the surface, it is rarely painted directly, and it is usually attached to the plywood. The woodware used for the furniture and the like must pass through two steps of using the adhesive board and painting, and the cost is higher.
Integrated board: not easy to deform
This is an emerging solid wood material, which is made of high-quality imported large-diameter logs and is intertwined with fingers. Due to the different processes, this board has excellent environmental performance and is 1/8 of the amount of formaldehyde allowed in the blockboard. On the other hand, this kind of plate made of solid wood such as American spruce can be directly painted and painted, which saves a process compared to blockboard.
MDF has better nail holding power than particle board
The particleboard is a natural material that is crushed into granules and pressed into a plate. It is the main material of the current cabinet. The MDF is formed by pressing powdered wood chips, and the flatness is good, but the moisture resistance is poor. In contrast, the nail holding force of the MDF is worse than that of the particle board. If the screw is loose after the screw is tightened, it is difficult to fix because the strength of the MDF is not high, so it is rarely used for the cabinet.
Facing the three plywood: save trouble and cheap
Multi-layer boards, also known as three-ply boards and plywoods, have different layers, and their advantages and disadvantages mainly depend on raw materials. The main use in the home decoration is the veneer plywood, which has already attached a very thin solid wood veneer to the three plywood in the factory. The veneer plywood is easy to use and inexpensive.
Experts advise: the purchase of wood depends first 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 milligrams per liter. If it exceeds 5 milligrams per liter, it is substandard. Secondly, it depends on the moisture content of the wood. When the moisture content of the wood is higher than the equilibrium moisture content of the environment, the wood will shrink and shrink, and vice versa. The main cause of cracking and deformation of wood is that the moisture content is too high or too low. Finally, don't just buy cheap when buying. The materials that are sold at low prices are usually materials that are shoddy and have serious formaldehyde. They should be purchased in the formal market. It is best to buy branded materials.
