Plywood with wood as the main raw material production of plywood. Because of the rationality of its structure and the fine production process. Can generally overcome the defects of wood improve and improve the physical. And mechanical properties of wood. Plywood production is reasonable use of wood. Improve wood properties of an important method. Classification of plywood a class of plywood is resistant to climate. Resistant to boiling water plywood. from here to there has the advantages of durability. High temperature resistance, steam treatment. The second type of plywood is water-resistant plywood . That can impregnated in cold water and hot water for a short time. Three types of plywood are moisture resistant plywood. can soaked in cold water for a short time, suitable for room temperature use.
