Introduction To The Selection Of Plates For Home Decoration

Expert reminds: The first thing to buy wood 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 the wood. When the moisture content of the wood is higher than the equilibrium moisture content of the environment, the wood will dry and shrink, 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 when buying. The materials that are sold at low prices are usually crude and formaldehyde materials that seriously exceed the standard. You should buy them in the formal market. It is best to buy branded materials. The following is an introduction of commonly used decoration boards.

1. Blockboard: good moisture resistance, cannot be painted directly

The middle of the blockboard is a core made of natural wood strips, with thin veneer glued on both sides, which is one of the most important materials in the decoration. It can be used for furniture, wooden doors and door covers, heating covers, curtain boxes, etc. It has good waterproof performance. When selecting, look at its internal wood, it should not be too shattered, the blockboard with a gap of about 3mm between the wood is suitable. Because the wood grain exposed on the surface is not beautiful, it is rarely painted directly, and usually veneered plywood is applied. The furniture and other wooden products made by it have to go through two processes: glue board and painting, and the cost is higher.

2. Integrated board: not easy to deform

This is a new type of solid wood material, which is made of high-quality imported large-diameter logs and is deeply processed and interlaced like fingers. Due to the different processes, this board has superior environmental performance, which is 1/8 of the 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 than blockboard.

3. MDF has poor nail holding power compared to particle board

Particleboard is natural wood crushed into granules and pressed into boards. It is currently the main material of cabinets. MDF is formed by pressing powdered wood chips after pressing, and the flatness is better, but the moisture resistance is poor. In contrast, the nail-holding force of MDF is worse than that of particle board. If the screws loosen after tightening, it is difficult to fix because the strength of MDF is not high, so it is rarely used as a cabinet.

4. Three-ply veneer: easy and cheap

Multi-layer board, also known as three-ply board and three-layer board, the number of different layers is different, its pros and cons mainly depends on the raw materials. At present, the main use in the home decoration is the veneer triple plywood, that is, the very thin solid wood veneer has been attached to the triple plywood in the factory. Facing triple splint is easy to use and cheap.
