Plywood is a thin board with three or more layers, which is made by cutting raw wood into veneer or planing into thin wood, and then gluing with an adhesive. Generally, an odd number of veneers are used, and the fiber directions of adjacent veneers are aligned and glued vertically. So there are odd layers of plywood such as three, five and seven.

From the structural point of view, the outermost veneer of the plywood is called the face plate, and the front face plate is called the face plate. It is the best quality single plate. The back plate is called the back plate, and the single plate with the second highest quality is used. The inner single plate is called the core plate or middle plate, which is composed of the worst single plate.

The manufactured plywood has the following characteristics:

First, plywood has all the advantages of natural wood, such as light weight, high strength, beautiful texture, insulation, etc., and can make up for some natural defects such as knots, small format, deformation, large vertical and horizontal mechanical differences.

Second, plywood production can make reasonable use of logs. Because it has no sawdust, one cubic meter of plywood can be produced for every 2.2-2.5 cubic meters of logs, which can be used instead of sawing about 5 cubic meters of logs into boards. For each cubic meter of plywood products produced, 1.2-1.5 cubic meters of residue can be produced. Rice, this is a better raw material for the production of MDF and particleboard.

Because plywood has the advantages of small deformation, large format, convenient construction, no warping, good tensile mechanical properties of horizontal stripes and so on. Therefore, this product is mainly used in various boards for furniture manufacturing, interior decoration, and residential construction. Followed by the industrial sectors such as shipbuilding, truck manufacturing, various military industries, light industrial products, and packaging.
