What’s the plywpood

Plywood is one of the commonly used materials for furniture manufacturers, and it is a kind of wood-based board. A group of veneers are usually glued together according to the wood grain direction of adjacent layers perpendicular to each other. Multi-layer boards are usually symmetrically arranged on both sides of the center layer or core. The slab made of the veneer after gluing is criss-crossed according to the direction of wood grain, and pressed under heating or non-heating conditions. The number of layers is generally an odd number, and a few have even numbers. The difference in physical and mechanical properties in the vertical and horizontal directions is small. Commonly used are multi-layer boards such as three-ply board and five-ply board. Multilayer boards can improve wood utilization and are a major way to save wood. It can also be used as a material for aircraft, ships, trains, automobiles, construction and packaging crates.
Plywood, also known as three-plywood and three-ply board, has different names for different layers. According to the thickness of 3-9 cm, it can also be called 3-9 cm board. Its advantages and disadvantages mainly depend on the raw materials. The price of each 1.2*4m board of Liu Anxin is 10-20 yuan. And mahogany and poplar are cheaper.
The main thing used in home decoration is the plywood veneer, that is, the very thin solid wood veneer has been pasted on the plywood in the factory. The veneer plywood is easy to use, and the price is cheaper than buying the veneer yourself and letting the construction team paste it.
The specifications of plywood are the same as those of building templates, basically: 1220×2440mm, and the thickness specifications generally include: 3, 5, 9, 12, 15, 18mm, etc. The main tree species are: camphor, willow, poplar, eucalyptus and so on.
The plywood has good structural strength and good stability. It has the advantages of light material, high strength, good elasticity and toughness, impact and vibration resistance, easy processing and painting, insulation, etc. The plywood contains a lot of glue, and the edge sealing treatment should be done during construction to reduce pollution during the day.
