Commonly used boards for decoration include solid wood panels, plywood, veneer panels, fine wood panels, etc. As for the uses and advantages and disadvantages of these types, do you know what you are about to decorate? Let’s take a look at the recommendations for purchasing wood for decoration.
1. Blockboard: good moisture-proof effect, can not be painted directly
The middle of the blockboard is a core made of glued 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 and 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 shredded, blockboard with a gap of about 3mm between the woods is appropriate. Because the exposed wood grain on the surface is not beautiful, it is seldom painted directly, and veneer plywood is usually attached. Furniture and other wooden utensils made with it have to go through the two processes of using glued boards and painting, and the cost is higher.
2. 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, which are interlaced and spliced like fingers. Due to different processes, this board has superior environmental 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 painted and painted, which saves a process compared with blockboard.
3. Medium Density Board: It has worse nail holding power than particleboard.
Particleboard is a natural wood crushed into particles and then pressed into a board. It is the main material for cabinets at present. MDF is formed by pressing powdered wood chips, with good flatness, but poor moisture resistance. In contrast, MDF has a weaker nail-holding force than particleboard. If the screws are loosened after tightening, the MDF is not strong enough to be fixed again, so it is rarely used for cabinets.
4. Three plywood veneer: easy and cheap
Multilayer boards are also called plywood and plywood. Different layers are called differently. Its quality depends mainly on the raw materials. Nowadays, the veneer three plywood is mainly used in home improvement, that is, very thin solid wood veneer has been pasted on the three plywood in the factory. The veneer plywood is easy to use and cheap.
Experts Remind:
► Firstly, the purchase of wood must look at 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 look for cheap when you buy. The materials sold at low prices are usually shoddy and formaldehyde seriously exceeding the standard. You should buy them in the formal market. It is best to buy branded materials.
