Method for producing high-performance environment-friendly eucalyptus plywood

Abstract

The invention discloses a method for producing high-performance environment-friendly eucalyptus plywood. The method includes the steps of 1, airing, wherein after eucalyptus is rotationally cut and veneers are obtained, the veneers are aired for 3 to 5 days; 2, veneer sorting, wherein veneer sorting comprises cutting, veneer splicing and repairing, the dried strip veneers and single veneers are cut into standard veneers and splicing veneers, and narrow-strip veneers are spliced into a whole veneer; 3, glue mixing, wherein bonding glue needed for production of the plywood is prepared according to preset components and the preset ratio; 4, hot pressing, wherein plate billets which are coated with glue and assembled are firmly glued under preset temperature and preset pressure; 5, edge trimming, wherein hot-pressed rough plates are trimmed into standard plates; 6, sanding, wherein the surface of the plywood is sanded. According to the technical scheme, i.e., the defects that in the prior art, material cost is high, service life is short, and safety and environment friendliness are poor can be overcome, and the advantages of low material cost, long service life and good safety and environment friendliness are achieved.

Description

technical field [0001] The invention relates to the technical field of wood board processing, in particular to a production method of 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 p...

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
