The large core board, also known as the blockboard, is made by cutting the logs into strips, splicing into cores, and processing the outer surface materials, generally in a five-layer structure. It is an indispensable wood product for wall decoration, top decoration and fine wood decoration in home decoration. It is mainly used as a panel for furniture, a keel frame for door and window frames. The surface material can be divided into three-layer plate, five-ply plate, etc. according to the number of layers. According to the tree species, it can be divided into Liuye, eucalyptus, teak, etc. The surface of the good quality blockboard panel is smooth and smooth, not easy to warp and deform, and can be sanded according to the surface. The board is divided into two types: one light and two sides. The two-sided light can be used as a decorative material for the key parts such as furniture panels, door and window frames.
Different materials and different quality. The large core board is divided into “excellent productsâ€, “first-class products†and “qualified products†according to the quality of the materials and the texture of the surface materials. There are also companies that mark the grades of grades A, double A and triple A, but this is only corporate behavior, which is inconsistent with national standards, which is currently not allowed on the market.
There are many kinds of wood core boards, such as poplar, birch, pine, and paulownia. Among them, poplar and birch are the best, the texture is dense, the wood is not soft and hard, the nail holding power is strong, and it is not easy to be deformed, and the paulownia The texture is very light, soft, absorbs large water, has poor nail holding power, and is not easy to dry. During the use of the produced sheet, when the water evaporates, the sheet is easy to dry and deform. The hard wood is hard, not easy to press, the splicing structure is not good, the nail holding power is poor, and the deformation coefficient is large.
