Do you understand the basic principles of plywood? Follow the editor of Cheapest Veneer Plywood to have a simple look!
In order to improve the anisotropy of natural wood as much as possible, and make the plywood have uniform characteristics and stable shape, generally plywood must comply with two basic principles in structure: one is symmetry; the other is that the fibers of adjacent layers of veneer are perpendicular to each other. The principle of symmetry requires that the veneers on both sides of the center plane of symmetry of the plywood should be symmetrical to each other regardless of the nature of the wood, the thickness of the veneer, the number of layers, the fiber direction, and the moisture content. In the same plywood, you can use a single tree species and thickness of the veneer, you can also use different tree species and thickness of the veneer; but the two layers of symmetrical veneer species and thickness on both sides of the center plane of symmetry should be the same. The front and back panels are not allowed to be the same tree species.


To make the structure of plywood meet the above two basic principles at the same time, its number of layers should be odd. Therefore, plywood is usually made of three layers, five layers, seven layers and other odd layers. The names of the various layers of plywood are: the surface veneer is called the surface board, the inner veneer is called the core board; the front surface board is called the front board, and the back surface board is called the back board; in the core board, the fiber direction is parallel to the surface board. It is called long core board or middle board. When composing the cavity table slab, the face plate and the back plate need to face outwards tightly.
To sum up, the editor of Cheapest Veneer Plywood tells: knowledge about the basic principles of plywood.
