The plywood is one of common furniture materials, is one of three large plates of an artificial plate, and can also be used as a material for airplanes, ships, trains, automobiles, buildings, packing boxes and the like. 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 and is a main way for saving the wood.
The plywood sanding is a processing process for grinding the surface of the wood in a large area by using sharp abrasive particles on an abrasive belt, and aims to remove unevenness caused by mechanical processing and wood structure so as to carry out surface decoration, and a large amount of dust with wood chips is generated in the operation process, so that the health of operators is seriously damaged; therefore, the sanding machine is matched with corresponding dust removal equipment, and the dust can be recycled if collected.
