Discussion on plywood
- Nov 19, 2018 -

Plywood is a three-layer or multi-layered plate material made of wood segments cut into veneer or sliced by wood, then glued with adhesives, usually with odd layers of veneer, and the fiber direction of adjacent layers of veneer is glued vertically to each other. Plywood is one of the commonly used materials for furniture, one of the three boards of wood-based panels, can also be used for aircraft, ships, trains, automobiles, buildings and boxes and other role materials. A set of veneer is usually glued vertically to each other in the direction of the wood grain of the adjacent layer, and usually its table plate and inner plate are symmetrically configured on both sides of the central layer or plate core. The slab, which is crisscross and fitted in the direction of wood grain, is pressed under the condition of heating or not heating. The number of layers is generally odd, and a few have even numbers. The physical and mechanical properties of vertical and horizontal directions are less different. Commonly used plywood types are plywood, Guean and so on.

Plywood can improve the utilization rate of wood, which is one of the main ways to save wood. The usual length and width specifications are: 1220x2440mm, while the thickness specifications are generally: 3, 5, 9, 12, 15, 18mm and so on. The main tree species are: Beech wood, mountain camphor, Willow Press, poplar, eucalyptus and so on.
