Description

Firm and durable type plywood

Technical Field

The utility model relates to the technical field of plywood, in particular to a firm and durable type plywood.

Background

The plywood is made up by using wood sections to make veneer by rotary cutting or using wood Fang Bao to make Cheng Baomu, using adhesive to make three-layer or multi-layer plate material, usually using odd-layer veneer and making the fibre directions of adjacent layers of veneer mutually perpendicular and making them be glued together. The plywood is one of common materials for furniture, is one of three artificial boards, and can also be used as a material for aircrafts, ships, trains, automobiles, buildings, packaging boxes and the like. A group of veneers are typically assembled and glued perpendicular to each other in the grain direction of adjacent layers, typically with the skins and inner layers symmetrically disposed on either side of the center layer or core. The plate blank is formed by longitudinally and transversely matching the glued single plates according to the wood grain direction, and is pressed under the condition of heating or non-heating. The number of layers is typically odd and the minority is even. The difference of physical and mechanical properties in the longitudinal and transverse directions is small. Typical plywood types are three-ply board, five-ply board and the like. The plywood can improve the utilization rate of wood and is a main way for saving wood.

The traditional plywood has poor moisture resistance due to the multilayer structure of the traditional plywood, and particularly in the environment climates with high humidity such as plum rains, the performances such as the strength and the quality of the plywood are easily affected due to the fact that the traditional plywood is easy to be subjected to moisture deformation.
