Description

A plywood with a moisture-proof structure inside

technical field

The utility model relates to the technical field of plywood, in particular to a plywood with a moisture-proof structure inside.

Background technique

Plywood is one of the commonly used materials for furniture, and it is one of the three major boards of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneers are usually assembled and glued together according to the direction of the wood grain of adjacent layers perpendicular to each other. Usually, the surface board and inner layer board are symmetrically arranged on both sides of the center layer or core. The slab made of the veneer after gluing is criss-crossed according to the direction of wood grain, and pressed under heating or non-heating conditions.

Commonly used plywood types include three-ply board, five-ply board, etc. Plywood can improve the utilization rate of wood and is a main way to save wood. Existing plywood is cut into veneers by wood sections or sliced into thin wood by wood squares, and then used Adhesive glued three or more layers of board-like materials, most of the plywood currently on the market has poor moisture resistance, and moisture will easily cause the glue to fail after moisture enters the inside of the board, resulting in loose deformation of the board.
