Selection skills of main wood and board for decora

  • Detail

There are many kinds of wood-based board products

there are a wide range of board samples in stores

decoration naturally cannot be separated from the main materials of woodworking materials: blockboard, integrated board, particleboard, density board, decorative panel and other boards. What is the role of these wood boards with different names in home decoration? The following is the explanation made by experts for us:

Blockboard: it has good moisture-proof effect and cannot be painted directly.

the middle of blockboard is a core made of natural wood strips bonded, and both sides are bonded with a very thin wooden skin, which 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: it is not easy to deform

this is a new solid wood material, which is made of high-quality imported large-diameter logs and is spliced like fingers. 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

medium density board has less nail holding force than particleboard

particleboard is the main material of cabinets at present, which is made of natural wood after being crushed into granules and pressed into boards. 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 names for different layers, and 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

experts remind: buying wood first 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, and vice versa. The main reason for wood cracking and deformation is that the moisture content is too high or too low. Finally, when buying, don't just try to be cheap. The materials sold at a low price are usually shoddy and formaldehyde seriously exceeding the standard. You should buy them in the formal market, and it's best to buy branded materials
