What are the advantages of plywood?

Plywood is a thin board with three or more layers, which is made by rotary cutting logs into veneers or planing wood into thin wood, and then gluing it with adhesive. Usually an odd number of layers of veneers are used, and the fiber directions of adjacent layers of veneers are aligned vertically and glued together. Therefore, there are odd number layers of plywood such as three-in-one, five-in-one, seven-in-one, etc.

1. Plywood not only has the advantages of wood, such as light weight, high strength, beautiful texture, insulation, etc., but it can also make up for some of the natural defects of wood, such as knots, small format, deformation, and large differences in vertical and horizontal mechanics.

2. Plywood production can make rational use of logs. Because it has no sawdust, every 2.2-2.5 cubic meters of logs can produce 1 cubic meter of plywood, which can be used instead of sawing about 5 cubic meters of logs into boards. For every 1 cubic meter of plywood produced, 1.2-1.5 cubic meters of residue can be produced. Rice, which is a better raw material for the production of medium density fiberboard and particleboard.

Plywood has the advantages of small deformation, large format, convenient construction, no warping, and good horizontal grain tensile properties. Therefore, this product is mainly used in various panels for furniture manufacturing, interior decoration, and residential construction. Secondly, it is used in industrial sectors such as shipbuilding, carriage manufacturing, light industrial products and packaging.

From a structural point of view, the outer veneer of plywood is called a panel, and the front panel is called a panel. It is made of good quality veneer. The front panel on the back is called the back panel, and is made of a single board with the next highest quality. The inner veneer is called the core board or the middle board, and is composed of poor quality veneer.
