The materials of edge-glued wood mainly include wood segments, wood squares, etc., which are made into veneers or veneers by rotary cutting or planing, and then glued together with adhesives. Usually, an odd number of veneers are used, and the fiber directions of adjacent layers are perpendicular to each other to enhance their physical properties.
Material composition
The main component of edge-glued wood is wood, including:
Wood segments: veneers are obtained by rotary cutting.
Wood squares: veneers are obtained by planing.
These raw materials are dried, glued, assembled, glued and other processes to form multi-layer plywood.
Manufacturing process
Raw material preparation: wood segments are peeled into veneers or wood squares are sliced into veneers.
Drying treatment: The veneers are dried to ensure that their moisture content is moderate.
Gluing: Adhesive is applied to the veneers.
Assembly: The glued veneers are assembled according to the principle that the grain directions of adjacent layers are perpendicular to each other.
Pressing: Pressing with or without heating to form a multi-layer structure of plywood.
Trimming: Cutting and trimming the formed plywood to meet different size and shape requirements.
