The plywood is a three-layer or multi-layer plate material formed by rotary cutting a wood section into veneers or slicing battens into veneers and then gluing the veneers by using an adhesive, usually odd-layer veneers are used, and the fiber directions of the veneers on adjacent layers are mutually vertical to be glued. A group of veneers are typically assembled and glued perpendicular to each other in the direction of the adjacent layers of wood grain, and the skins and inner sheets are typically symmetrically disposed on either side of the center layer or core. The glued veneer is pressed into the wood grain board blank by the criss-cross matching of the glued veneer according to the wood grain direction under the condition of heating or not heating. The number of layers is generally odd, and a few are even. The difference of physical and mechanical properties in the longitudinal and transverse directions is small. The types of plywood commonly used are plywood, plywood and the like. The plywood can improve the utilization rate of the wood, is a main way for saving the wood, and the number of layers of the plywood is an odd number to ensure that the structure of the plywood simultaneously conforms to the two basic principles. Therefore, plywood is usually made of three layers, five layers, seven layers and other odd number layers. The name of each layer of the plywood is: the surface veneer is called a surface veneer, and the inner veneer is called a core veneer; the front surface of the front panel is called a panel, and the back surface of the front panel is called a back panel; in the core board, the core board in which the fiber direction is parallel to the face board is called a long core board or a middle board.
