Compared with large core board, plywood has stable shape, flexible texture, not easy to deform, good transverse tensile resistance, better moisture-proof performance than density board and particleboard, and less amount of adhesive. That is to say, assuming that the same adhesive and wood core are used for the above several boards, plywood is the most environmentally friendly.
Plywood is one of the most commonly used materials for furniture and one of the three major panels of wood-based panels. At present, it is widely used in furniture production. The reason why it can be widely used is that plywood can improve the utilization rate of wood and is the main way to save wood.
It is a three-layer or multi-layer plate-like material formed by turning wood sections into veneers or planing wood into thin wood, and then gluing with adhesives. Usually, odd layers of veneers are used, and the fiber directions of adjacent layers of veneers are glued perpendicular to each other.
However, plywood is also divided into three categories. One category is weather resistant and boiling water resistant plywood. This kind of plywood has good durability, boiling resistance, and can be steam treated and can be used outdoors; One is water-resistant plywood, which can withstand cold water immersion and short-term hot water immersion, but is resistant to boiling; One is non moisture resistant plywood. Plywood has different strength, and plywood with different strength has different uses.
