BEIJING, Dec. 7 /PRNewswire-Asia/ -- Frbiz.com, one of China's leading B2B search platforms with more than 30 B2B industry websites to its name, compares four kinds of wooden board.
Decoration cannot lack natural wood material: integrated board, flake board, density board, and veneer board play a certain role in decoration. The following is Frbiz's explanation:
Medium-density board does not hold nails as well as flake board
Flake board is a natural timber crushed into granules and then compressed into boards; it is the main material for cabinets.
Medium-density board is made of compressed wood powder, which is flatter, but less resistant to moisture.
In contrast, medium-density board's nail-holding ability is worse than that of flake board. If screws require tightening after becoming loose, due to the relative weakness of MDF, repair is difficult, so it is seldom used to do cabinets.
Veneer three-layer plywood: hassle-free and cheap
Multiple-layer plywood is also called three-layer plywood; depending on the name of the wood, the layers may be made of different materials. Its advantages and disadvantages mainly depend on the raw materials used.
Most decorative wood is veneer three-layer plywood. In the factory, a very thin wood veneer is attached to the three-layer plywood. Veneer three-layer plywood is easy to use and the price is pretty cheap.
Block-board is moisture-proof and cannot be directly painted upon
The middle of block-board is made of adhesive natural wood; a thin wood veneer that is the most important decorative material adheres to each side. This kind of wood can be used to make furniture and doors, heating covers, and window curtain boxes; its waterproof performance is good.
In terms of selection, look at its internal timber. It should not be too broken; a 3mm crack the wood is suitable.
As the surface of exposed wood is not pretty, it is seldom directly painted; instead, a plywood veneer is usually affixed (http://frbiz.com/catalog/14000000/furniture_furnishings.html ). Since the production of wood furniture includes an adhesive plating stage and painting stage, it will cost more.
Integrated board does not warp easily.
This is a new solid wood material made of high quality imported finely processed large-diameter logs.
As the production process is different, this board has superior performance; its formaldehyde content is only 1/8 that of block-board.
Spruce and other wood from the United States can be directly painted, which eliminates one extra step.
Frbiz's reminder:
When purchasing wood, first one should pay attention to whether it is environmental friendly. According to the law, indoor building materials release of formaldehyde must be less than or equal to 1.5 milligrams per litre, and materials whose release exceeds 5 milligrams per litre shall be considered sub-standard.
Second, look at wood moisture content; when the wood moisture content is higher than the environmental equilibrium moisture content, the wood will dry and shrink; if the reverse is true, it will expand. Cracking occurs mainly due to moisture content being too high or too low.
Finally, when purchasing, do not be cheap, low priced materials are usually shoddy and their release of formaldehyde excessive, so should go to a real market to buy, and it's best to buy brand name materials.
