Basic principles and use characteristics of Interior Plywood for Indoor Using
- Jan 24, 2019 -

In order to improve the characteristics of the natural wood, the plywood for indoor use can make the plywood characteristics uniform and stable in shape. In general, the plywood must observe two basic principles in structure: one is symmetrical; the other is The adjacent layer veneers are perpendicular to each other. The principle of symmetry is to require veneers on both sides of the symmetry center plane of the plywood, regardless of the nature of the wood, the thickness of the veneer, the number of layers, the direction of the fibers, the moisture content, etc., should be symmetrical to each other.

Interior Plywood for Indoor Using In the same plywood, a single tree and a thickness of veneer can be used, or a veneer of different tree species and thickness can be used; however, any two layers of mutually symmetrical veneer trees and thicknesses on both sides of the symmetrical central plane are the same. The back panel allows for not the same species.

The structure of Interior Plywood for Indoor Using meets the above two basic principles at the same time, and its number of layers should be odd. Therefore, plywood is usually made into three layers, five layers, seven layers and other odd number of layers. The names of the layers of the plywood are: the surface veneer is called the table, the inner veneer is called the core board, the front panel is called the panel, and the back panel is called the back panel. In the core board, the fiber direction is parallel to the board. It is called a long core board or a medium board. When forming the cavity plate slab, the panel and the back plate must face out.
