Main Components of Plywood

Plywood is a multi-layered board formed by stacking wood veneers and adhesives in layers and heat-pressing them. Different types and specifications of plywood can be customized according to specific uses and needs. The main components of plywood include the following parts:

1. Wood flakes: An important component of plywood is the thin flakes that are cut from wood. Common woods include pine, birch, walnut, oak, etc. The thickness and size of the sheets can be adjusted according to the desired plywood specification and use.

2. Adhesives: Another key ingredient in plywood is adhesives, which are used to bond the wood veneers. Common adhesives include urea-formaldehyde glue, phenolic glue, phenol ammonia glue, polyurethane glue, etc. The choice of adhesive depends on the required strength, moisture resistance and durability requirements.

3. Heat and pressure treatment: The manufacturing process of plywood usually includes heat and pressure treatment. High temperature and pressure are applied between the stacked layers of plywood to allow the adhesive to work and form a strong bond.

4. Auxiliary materials: In addition to wood flakes and adhesives, plywood may also contain some auxiliary materials, such as moisture-proof agents, reinforcing agents, and preservatives. These materials can improve the performance and durability of plywood.
