Plywood is a three-layer or multilayer board like material made of wood segments that are peeled into veneer or sliced into thin wood by wood planing, and then glued with adhesives. Usually, odd layers of veneer are used, and the fiber directions of adjacent layers of veneer are perpendicular to each other.
Plywood is one of the commonly used materials for furniture and is a kind of man-made board. A group of veneers is usually glued with each other perpendicular to the grain direction of adjacent layers. Usually, the surface and inner layers are symmetrically arranged on both sides of the central layer or the core.
The slab is made of glued veneer in a crisscross manner in the direction of wood grain,Pressed with or without heating.
The number of layers is usually odd, and a few are even. Physical and mechanical properties in vertical and horizontal directions.The quality difference is small.
Three plywood and five plywood are commonly used.
Plywood can improve the utilization rate of wood, which is a main way to save wood.
