A Brief Introduction To Plywood

Plywood is a three-layer or multi-layer board-like material that is made of wood segments into veneers or sliced into veneers, and then glued with adhesives. The fiber directions are glued perpendicular to each other.

Plywood is one of the commonly used materials for furniture. It is one of the three major wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneer is usually formed by gluing the adjacent layers of wood grains perpendicular to each other. Usually, the surface plate and the inner layer are symmetrically arranged on both sides of the center layer or the core. It is a slab made of glued veneers crisscrossed in the direction of the wood grain, and pressed under the condition of heating or no heating. The number of layers is generally odd, and a few are even. The physical and mechanical properties in the vertical and horizontal directions are slightly different. Commonly used plywood types are three plywood, five plywood and so on. Plywood can improve the utilization rate of wood and is a main way to save wood.
