Abstract
Description
Technical Field
[0001] The utility model relates to the field of building materials, in particular to an environmentally friendly building plywood. Background Art
[0002] Plywood is a three-layer or multi-layer plate-like material made by peeling wood segments into veneers or planing wood squares into veneers, and then gluing them with adhesive. Usually, an odd number of veneers are used, and the fiber directions of adjacent veneers are glued perpendicular to each other. Plywood is one of the commonly used materials for furniture and one of the three major wood-based panels. It can also be used as material for airplanes, ships, trains, cars, buildings, and packaging boxes. A group of veneers are usually assembled and glued in such a way that the grain directions of adjacent layers are perpendicular to each other. Usually, the surface board and the inner layer board are symmetrically arranged on both sides of the center layer or the core. The slabs are made of veneers that are coated with glue and staggered in the direction of the wood grain. They are pressed under heating or non-heating conditions. The number of layers is generally odd, and a few also have even numbers. The physical and mechanical properties in the longitudinal and transverse directions are slightly different. Commonly used types of plywood include three-ply board, five-ply board, etc. Plywood can improve the utilization rate of wood and is a major way to save wood. Environmentally friendly plywood is a kind of building material.
