Editor's note: Plates are an indispensable main material in home decoration. We often hear dozens of kinds in the building materials market. It is difficult to tell who is who, and will be fooled if not careful. Red Net Home is hereby launching the plate of the decoration book, teaching you the choice of plate selection.
Teach you to identify
1. Blockboard: good moisture resistance, can not be directly painted
In the middle of the blockboard is a core made of natural wood strips, with thin veneers 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., and its waterproof performance is good. 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.
2. Integrated board: not easy to deform
This is an emerging solid wood material, which is made of high-quality imported large-diameter logs and is intertwined with fingers. Due to the different processes, the board has excellent environmental performance and is one-eighth of the amount of formaldehyde allowed in the blockboard. In addition, the plate made of solid wood such as American spruce can be directly painted and painted, which saves a process compared to the blockboard.
3. MDF: the nail holding force is worse than the particle board
The particleboard is a natural material that is crushed into granules and pressed into a plate. It is the main material of the cabinet. The MDF is formed by pressing powdered wood chips, and the flatness is good, but the moisture resistance is poor. In contrast, the MDF has a lower nail holding power than the particle board.
4. Facing the three plywood: save trouble and cheap
Multi-layer boards, also known as three-ply boards and plywoods, have different layers, and their advantages and disadvantages mainly depend on raw materials. 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 inexpensive.
Shopping tips
At first glance, the surface of the blockboard should be flat, without warping, deformation, no blistering or dent; the core strips are evenly arranged, and the core strips are free of decay, breakage, wormholes, thrift and so on.
Two sway, lift the corner of the board and shake it up and down, and listen to the sound of degumming or cracking.
Three knocks, tapping the surface of the board with a sharp-nosed instrument, and if the sound is crisp and clean on the surface, the density is relatively high. If the sound is dull, the density is low, and there is no difference in listening to the sound.
Four questions, ask the tree species, there are many kinds of raw materials for wood board, and more use of cork; hard wood is hard, not easy to suppress, and requires advanced technology. At present, the Malaysian sheet metal process is the best, using double-sided whole willow material stable structure, harmful gas The release is certified by the US CARB (this is currently the most stringent limit in the world).
Five smells, if the board emits a fragrant smell of wood, it means that the amount of formaldehyde released is small; if the smell is pungent, it means that the amount of formaldehyde released is more.
Six check, check the report, the test report will clear the standard, there will be a national standard reference, the more the national standard is exceeded, the better, the formaldehyde emission ≤ 0.5mg / L, in line with the E0 standard, formaldehyde emission ≤1.5mg/L, in line with E1 standard, formaldehyde emission ≤0.3mg/L meets the California CRAB standard, which is also the most stringent environmental standard in the world.
