A kind of preparation method of plywood

Abstract

The invention discloses a preparation method of plywood. Placement: the veneer soaked in the compound agent is fixed inside the placement frame, and the placement frame equipped with the veneer is placed in the middle of the lower splicing frame at the top of the bottom plate, and the screw rotates The upper splicing frame body moves downward and covers the top of the lower splicing frame body. The upper splicing frame body and the lower splicing frame body of the present invention are spliced ​​together to form a sealed frame, which functions as a sealed tank. The veneer soaked in the compound agent inside the frame is in a sealed environment, and the heating plate is used to heat the inside of the sealing frame, and at the same time, the air inside the sealing frame is sucked into the air pressure tank by using the pressure regulating valve and the connecting air channel, thereby improving the sealing The pressure inside the frame makes the veneer in a high-temperature and high-pressure environment inside the sealed frame, which can promote the diffusion of the soaked composite agent molecules into the veneer, improve the toughness of the surface fibers of the veneer, and effectively enhance the fracture resistance of the veneer.

Description

Technical field [0001] The present invention relates to the preparation of plywood, and is specifically a method of preparing a plywood. Background technique [0002] Plywood is one of the common materials of furniture. It is one of the three major panels of the people. It is also available for aircraft, ships, trains, cars, buildings and packages. The plywood is spirally cut into a single plate or by wood. Slices of planer into thin wood, then glued with adhesive, usually use an odd layer single sheet, and make the fibers in the adjacent layer single plates are vertically glued vertically, usually the table plate and The inner plate is symmetrically configured on both sides of the central layer or board, and the single plate used by the plywood requires soaking composites before gluing to increase the toughness and pressure resistance of the single sheet; [0003] However, after the plywood, the plywood is directly flushed, the composite agent is not fully spread to the inside o...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method for preparing plywood, which can effectively solve the problem that the veneer used in the above background technology is soaked in a compounding agent and then directly rinsed and glued. The pressure ability is weak, which makes the poor quality of plywood affect its normal use.
