Explanation

A board like material made by rotating and cutting wood segments into single boards or planing wood into thin pieces, usually glued vertically along the grain direction of adjacent layers of wood. Since the veneers on both sides of the central plane of plywood are symmetrical, and the fiber directions of adjacent layers of veneers are perpendicular to each other, the shrinkage, expansion and strength of veneers in all directions can be mutually constrained and supplemented. Therefore, plywood is not prone to crack, warpage and other defects in use, and wood defects (knots, etc.) can be removed, dispersed or covered, so that the material is more uniform, and log diameter is not limited, Make a large flat or curved surface. plywood is widely used, mainly in furniture, interior decoration, vehicles, ships, aircraft, architecture and other fields.
