Advantages and disadvantages of plywood for furniture
Plywood is a three-layer or multi-layer board material made of wood segments that are cut into veneers or sliced into veneers, and then glued together with adhesives, usually with odd layers of veneers, and adjacent layers of veneers The fiber directions are glued perpendicular to each other.
Advantage:
1. Light weight, clear lines, insulation, high strength, and not easy to deform.
2. The construction is convenient, not warped, and the horizontal grain has good tensile mechanical properties.
Disvantages:
1. The general cost is high.
2. The surface of the plywood is not as smooth as the density board. When the plywood is used as the base layer, and the fireproof board, aluminum-plastic board and other decorative panels are bonded on the surface, it is not as firm as the medium density board as the base layer. Plywood is one of the commonly used materials for furniture. It is one of the three major wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneer is usually formed by gluing the wood grain directions of adjacent layers perpendicular to each other. Usually, the surface plate and the inner layer are symmetrically arranged on both sides of the center layer or the core. It is a slab made of glued veneers crisscrossed in the direction of the wood grain, and pressed under the condition of heating or no heating. The number of layers is generally odd, and a few are even. The physical and mechanical properties in the vertical and horizontal directions are slightly different. Commonly used plywood types are three plywood, five plywood and so on.
Plywood can improve the utilization rate of wood and is a main way to save wood. The usual length and width specifications are: 1220×2440mm, while the thickness specifications are generally: 3, 5, 9, 12, 15, 18mm, etc. The main tree species are: camphor, willow, poplar, eucalyptus and so on.
