Many consumers choose large core boards, one looks at the weight, and the other looks at the price. In fact, the heavier the core board, the worse the quality. Because the greater the weight, the more the board is used. This large core board made of miscellaneous wood is not nailed at all, so it cannot be used.
1. Blockboard - large core board: good moisture-proof effect, can not directly paint the middle of the blockboard is made of natural wood strips bonded together, the two sides are glued with very thin veneer, as the name suggests big core board, is decoration One of the most important materials. It can be used for furniture and wooden doors and door covers, heating covers, curtain boxes, etc. Its waterproof and moisture-proof performance is superior to particleboard and MDF. When selecting the wood inside, it should not be too broken, and the gap between the woods should be 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. Woodware such as furniture made of large core boards has to go through two processes of using adhesive sheets and painting, and the cost is higher. The large core board is divided into 3, 5, and 9 PCT plates according to the thickness. You can choose according to the pressure and strength to be accepted. The thicker the price, the higher the price.

Many consumers choose large core boards, one looks at the weight, and the other looks at the price. In fact, the heavier the core board, the worse the quality. Because the greater the weight, the more the board is used. This large core board made of miscellaneous wood is not nailed at all, so it cannot be used.

In addition, the price of a very low-core large core board will certainly be very poor. It is not a big gap, it is the use of unqualified wood. Therefore, when you choose, it is best to choose a large core board of about 100 yuan. The price of this large core board is relatively stable. The market sells a large core board with a price of 50-55 yuan, which cannot be used at all.

The choice of a large core board is to look at the appearance: one side of the large core board must be a whole board, and the other side only allows a seam. In addition, the surface of the large core board must be dry and clean.

In addition, when you choose a large core board, you must cut a corner and check the quality inside. The small wooden strips that are spliced ​​inside cannot have a gap of more than 5 mm. Wood with bark, boring and knots cannot be used. A large-quality core board with good quality, in which small wooden strips are connected with a zigzag-shaped mouth.

In use, the large core board can only be "shun" on the long side and cannot be used horizontally. In addition, the large core board can not be used as a panel, and a layer of plywood should be attached as a panel on the outside, otherwise there will be problems such as paint blistering.

2, laminated material, not easy to deform This is a new type of solid wood material, using high-quality imported large-diameter logs, deep processing and imaging fingers like staggered stitching of wood. Due to different processes, the environmental performance of this board is superior. It is 1/8 of the amount of formaldehyde allowed in the large core board. The price is about 200 yuan per sheet, which is slightly more expensive than the high-grade large core board.

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 with the large core board. Finally, the construction cost may be flat.

3, MDF than the particle board holding nail force difference particle board is natural wood pulverized into granules, pressed into a board, 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.

4, facing three plywood and cheap multi-layer board, also known as three plywood and plywood, the different layers are called different. According to the thickness of 3-9 cm, it can also be called 3-9 PCT. Its pros and cons mainly depends on raw materials, and the price of 4m board is 10-20 yuan. The peach core and poplar are cheaper.

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 the price is cheaper than buying a veneer for the construction team.

5, melamine double-ply board, not afraid of water and fire This board is shiny on both sides, very hard, not afraid of water and fire, mainly used in furniture and cabinets. The 4m-size plates range from 80 yuan to 140 yuan each.

6, veneer, manufacturing and solid wood effect veneer is wood veneer with high-grade wood with obvious wood grain, very thin, the thinnest is only 0.3mm, the thickness is only 2-3mm. The color of common veneer is from Light to deep, there are dozens of varieties such as cherry, maple, white peony, red peony, ash, white oak, red oak, teak, rosewood, walnut, white shadow wood, red shadow wood, etc. Philippines.

For large-scale use, it is best to buy the facing three plywood directly. If the panel is used separately for a unique effect, a higher process is required.

When the moisture content of the treated wood is higher than the equilibrium moisture content of the environment (the annual average moisture content in Beijing is 11.4%), the wood will dry 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. Qualified wood requires high temperature cooking and drying procedures at the factory to achieve local moisture levels. Therefore, the moisture content of wood is particularly important.

Experts advise: Don't show cheap experts tell us: Don't be cheap, the materials that are sold at low prices are usually materials that are shoddy and have serious formaldehyde. It is best to buy in the formal market, and the purchase channels here are more secure. Buy branded materials. Since wood is the main material in home decoration, the number of purchases is large, so be cautious when purchasing, it is best to bring with experienced people or professional buyers. It can also be entrusted to the decoration company to purchase. First, they have a stable supply unit, the price may be lower, and second, once the quality has problems, the responsibility is clear and the problem is solved.
