Plywood is a relatively common type of sheet, many housing construction, furniture manufacturing will be used plywood, what exactly is plywood? What are the characteristics of plywood?
A. What is plywood?
1, Plywood is made of wood segments rotary cut into veneer or from wood planed into thin wood, glued with adhesive to make a three-layer or multi-layer board material, usually with an odd number of layers of veneer, and make the adjacent layers of veneer fiber direction perpendicular to each other glued together to make a kind of plate.
2、Plywood is one of the commonly used materials for furniture, and is one of the three major boards for airplanes, ships, trains, automobiles, buildings and packing boxes, etc. -The group of veneer is usually glued together vertically according to the direction of the wood grain of adjacent layers, usually with the surface and inner plies symmetrically configured in the center layer or on both sides of the core.
3, Plywood is usually made into three layers, layers and other odd number of layers. The name of each layer of plywood is: the surface veneer is called the surface board, the veneer of the layer is called the core board; the front surface board is called the panel, the back surface board is called the back board; the core board, the fiber direction parallel to the surface board is called the long core board or middle board. In the composition of the cavity table slab slab, the panel and back panel must be tight face out.
B. What are the characteristics of plywood?
1, Plywood has a light weight, good bending resistance, convenient transportation and construction, beautiful texture, to make up for some of the defects of the natural generation of wood, has a good decorative. In some parts of the structure that need to bear the weight, the use of fine core board will have more strength.
2, Plywood has excellent bending resistance, not easy to deformation, transportation and construction are more convenient, has a good decorative effect.
3, Plywood in the production process, the production of sawdust, can be a reasonable and effective use of raw wood resources, the utilization rate of natural wood, is an important way to save wood. Plywood is a kind of artificial board, commonly used in furniture making, aircraft, car, construction and packaging boxes. Plywood has many characteristics such as light weight and good decorative properties.
