Some blockboards cut corners, the gap between the solid wood strips is large, if there is a nail in the gap, there is basically no nail holding force.
Consumers can look at the sun when they choose, and the gap between the solid wood strips will be white. If the glue strength of the blockboard is not good, there will be a "beep" opening sound at the corner. If the large core board emits a fragrant wood smell, it means that the amount of formaldehyde released is small; if the smell is pungent, it means that the amount of formaldehyde released is large (natural logs also contain trace amounts of aldehydes in nature).
The quality of blockboard is very different and should be carefully checked when purchasing. First of all, see if the core material is dense, whether there are obvious seams and decaying wood strips, whether there are obvious seams and decaying wood strips, there may be eggs in the decaying wood strips, and insects will occur in the future; The phenomenon of filling the putty, this phenomenon is generally to compensate for the internal cracks or voids; then it is to use the sharp-mouthed instrument to strike the surface of the board, to hear whether the sound is very different, if the sound changes, there is a cavity inside the board. These phenomena will weaken the overall bearing capacity of the board, and the uneven long-term stress will cause the sheet structure to be distorted and deformed, which will affect the appearance and use effect.
Plywood
Plywood is made of three or more layers of solid wood veneer or thin plate adhesive. Commonly, there are three plywood, five plywood, nine plywood and twelve plywood (commonly known as plywood, five PCT, and nine PCT). Twelve PCT board), good structural strength and good stability. Plywood has a large amount of glue, and it should be sealed when it is used to reduce pollution.
Plywood is mainly used for various wood products such as the bottom plate of decorative panels and the backboard of panel furniture. Plywood is selected mainly for its formaldehyde emission and bonding strength. If the gluing strength of the plywood is not good, it is easy to fall apart. When selecting, pay attention to whether the nominal thickness of the plywood matches the actual thickness. Pay attention to the following points when choosing plywood:
1 plywood has the difference between front and back. When selecting, the plywood should have a clear wood grain, a smooth and smooth front surface, and no roughness.
2 Plywood should not be damaged, bruised, bruised, and smashed.
