Plywood is a board made by cutting logs along the growth ring direction into large sheets of veneer, drying and gluing them, and then assembling and bonding them according to the principle of perpendicular wood grain direction between adjacent veneer layers. The number of layers on a single board is odd, usually ranging from three to thirteen layers. Common types include plywood, five plywood, nine plywood, and thirteen plywood (commonly known as three millimeter board, five millimeter board, nine millimeter board, and thirteen millimeter board in the market). The outer front panel is called the panel, the reverse panel is called the back panel, and the inner panel is called the core board.
One type of plywood is climate resistant and boiling water resistant, which has the advantages of durability, high temperature resistance, and steam treatment;
The second type of plywood is water-resistant plywood, which can be immersed in cold water and short-term hot water;
The three types of plywood are moisture resistant plywood, which can be soaked in cold water for a short time and is suitable for indoor use at room temperature. Used for furniture and general building purposes;
The four types of plywood are non moisture resistant plywood, which can be used indoors under normal conditions. Generally, the materials used for plywood include beech, basswood, ash, birch, elm, poplar, etc.
