At present, there are Pinus sylvestris var. mongolica on the market, with straight texture, moderate structure, light and soft material, good drying performance, and it is the best board. There is also a particle board, which has a flat surface and strong decorative property; Both static bending strength and internal bonding strength are high; Excellent processing performance; Small warping deformation, good dimensional stability. Its disadvantages are large water absorption thickness expansion rate, large product weight, low nail holding force, and it is not suitable for multiple disassembly and assembly. Density board is a good material for making furniture because of its impact resistance and easy reprocessing.
