Description

Technical Field

[0001] The utility model relates to the technical field of plywood, in particular to a plywood with good earthquake resistance effect. Background Art

[0002] Plywood is one of the commonly used materials for furniture. It is a kind of man-made board. A group of veneers are usually assembled and glued together in the direction of the wood grain of adjacent layers at right angles to each other. Usually, the surface panels and inner layers are symmetrically arranged on both sides of the center layer or core. The slabs are made by staggering the glue-coated veneers in the direction of the wood grain. They are pressed under heating or unheating conditions. The number of layers is generally odd, and a few have even numbers. The physical and mechanical properties in the vertical and horizontal directions are slightly different. Commonly used ones are three-ply boards and five-ply boards.
