Method for processing high-performance environment-friendly eucalyptus plywood

Abstract

The invention discloses a method for processing high-performance environment-friendly eucalyptus plywood. The method comprises the following steps: (1) airing, wherein veneers are obtained through rotary cutting of eucalyptus and then aired for 10 days; (2) veneer arrangement, wherein the veneer arrangement comprises shearing, veneer splicing and repairing; dried strip-shaped veneers and piece-shaped veneers are shorn into standard veneers and spliced veneers, strip veneers are spliced into a whole veneer; (3) glue mixing: wherein adhesion glue for plywood production is mixed according to preset components and ratio; (4) hot pressing, wherein slabs having undergone gluing and assembly well are firmly glued through preset temperature and preset pressure; (5) final trimming, wherein flag slabs having undergone hot pressing well are cut into standard plates; and (6) sanding, wherein the sanding treatment is performed on the surface of the plywood. According to the technical scheme, the method can overcome the shortcomings of high material cost, short service life and poor safety and poor environmental protection property in the prior art so as to have the advantages of low material cost, long service life and good safety and good environmental protection property.

Description

technical field [0001] The invention relates to the technical field of wood board processing, in particular to a processing method for high-performance and environment-friendly eucalyptus plywood. Background technique [0002] Plywood is also called plywood, commonly known as thin core board. It is made of three or more layers of one millimeter thick veneer or thin plate glued by hot pressing. Plywood has the advantages of small deformation, large format, convenient construction, no warping, and good tensile mechanical properties of transverse grains, so it is widely used in furniture manufacturing, interior decoration, residential construction, shipbuilding, carriage manufacturing, various military and light industrial products And packaging and other industrial sectors. [0003] In recent years, with the rapid development of upstream and downstream industries such as real estate, furniture, construction engineering, and logistics packaging, the market demand for plywood ...

AI Technical Summary

Problems solved by technology

[0004] In the production of plywood, hot pressing is the key procedure. At present, most manufacturers of plywood use formaldehyde or urea resin in the hot pressing process, which will release free formaldehyde gas and cause serious formaldehyde pollution.

Moreover, due to the level of production technology, the technical indicators of the produced plywood are not high enough in terms of wear resistance, corrosion resistance, static bending strength, bonding strength, impact resistance, etc., and cannot better meet market needs.

[0005] In the process of realizing the present invention, the inventors found that at least there are defects such as high material cost, short service life and poor safety and environmental protection in the prior art
