A kind of production technology of wooden plywood

Abstract

The invention belongs to the technical field of plywood production, and specifically discloses a production process for wood plywood. The plywood used by the process has characteristics such as high strength, corrosion resistance and low manufacturing cost, and can be widely applied to production of wood floor. Meanwhile, the process can change a proportion of hydrogen peroxide, ammonia water andan aqueous solution according to different kinds of wood, so that bleaching of wood skin is more sufficient; the wood skin is dried to prevent bleaching agent residues from corroding wood skin after the bleaching agent is cleaned by clear water; liquid nitrogen is used for performing instant freezing on the wood skin for ten minutes, and is placed under a normal-temperature environment for half anhour by three times in a reciprocating mode, so that the dyed wood skin has complete dyeing, is not liable to fade, is free of colour difference; and meanwhile, corrosion resistance of the plywood isreinforced.

Description

technical field [0001] The invention belongs to the technical field of plywood production, in particular to a production process of wooden plywood. Background technique [0002] Plywood is one of the commonly used materials for furniture, and it is one of the three major boards of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. Plywood has the characteristics of high strength, corrosion resistance and natural texture, and is widely used in the production of wooden flooring. [0003] Wooden floor refers to the floor made of wood. Wooden flooring produced in China is mainly divided into six categories: solid wood flooring, laminate flooring, solid wood composite flooring, multi-layer composite flooring, bamboo flooring and cork flooring, as well as the emerging wood-plastic flooring. Plywood, most of the wooden floors produced in the production of existing wooden floors are single-layer wooden floors, which are e...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art and solve the problems of high production cost, low strength, weak corrosion resistance, easy fading, uneven distribution of glue in plywood, low extrusion efficiency and inconvenient disassembly and maintenance of the existing wooden floor, the present invention A wood plywood production process is proposed. The nuts can be used to detach the plywood and the frame, which is convenient for maintenance. Through the rotation and extrusion of a single extrusion roller, the plywood can be shaped more comprehensively, and there will be no uneven distribution of glue. The curved surface setting at both ends of the extrusion rod can increase the moving speed of the extrusion wheel
