The difference between density board and plywood

1. Different production techniques

Plywood is a three-layer or multi-layer plate material made of veneer or veneer cut by wood planer and glued with adhesive. Density board is the wood or other plants separated into fibers, the use of fiber interweaving and its own inherent binding material, or the application of adhesive, under the condition of heating or pressure, made of the board.

2. Different product categories

Plywood is divided into four categories according to its gluing strength: one is resistant to climate, resistant to boiling water plywood. This type of plywood is durable, resistant to boiling or steam treatment, and can be used outdoors; The second type plywood is water-resistant plywood, which can be impregnated in cold water and hot water for a short time. The third type of plywood is moisture-resistant plywood, which can be impregnated in cold water for a short time and is suitable for indoor use at room temperature. Used for furniture and general building purposes; 4 kinds of plywood is not be able to bear tide plywood, use below indoor normal state, plywood of general use has ju wood, basswood, ash, birch, elm, poplar with material.

The density board can be divided into three types according to its density: low density board, medium density board and high density board.

3. Differentiation of performance and use

Plywood is mainly used for building construction, interior wall decoration and door panel, etc., on the outer surface of the model, such as the place of arc, it has the characteristics of light weight and good bending; Density board is mainly used in furniture manufacturing, building materials, vehicle and ship manufacturing, packaging materials and other fields. The surface of plywood is not as smooth and flat as that of density board. Compared with density board, the moisture content of plywood is more stable, and compared with density board, plywood has better moisture resistance and stronger nail holding force.
