Plywood is a three-layer or multi-layer plate-like material made of wood segments that are rotary cut into veneer or cut into thin wood by wood planer, and then glued together with adhesive, usually with odd layers of veneer, and the fiber direction of adjacent layers of veneer is glued perpendicular to each other. Plywood plywood is the main raw material of the production of plywood, due to its rational structure and fine processing in the production process, can largely overcome the defects of wood to greatly improve and improve the physical and mechanical properties of wood, plywood production is an important method to fully and rationally use wood and improve the performance of wood.
1. Plywood concept: plywood is made of three or more layers of solid wood veneer or thin board about one millimeter glued and hot-pressed, and the common ones are three plywood, five plywood, nine plywood and twelve plywood (commonly known as plywood, five centiboard, nine centiboard, twelve-centiboard).
2. Plywood characteristics: good structural strength and good stability. The plywood has a large glue content, and the edge sealing should be done during construction to reduce pollution during the day.
3. Plywood use: Plywood is mainly used for various wood products such as the bottom plate of decorative panels and the back plate of panel furniture.
4. Plywood selection: The selection of plywood mainly depends on its formaldehyde emission and gluing strength. If the gluing strength of the plywood is not good, it is easy to fall apart. When choosing, pay attention to whether the nominal thickness of the plywood matches the actual thickness.
