Manufacturing method of laminated veneer lumber

Abstract

The invention discloses a manufacturing method of a laminated veneer lumber, which comprises the following steps of: 1) material preparation; 2) carbonization; 3) maintaining; 4) gluing and laying up; 5) cold pressing; 6) hot pressing; 7) edging and sawing; 8) and sanding and packaging. The manufacturing method of the laminated veneer lumber is simple, and the manufactured laminated veneer lumber has good size stability and high structural strength and is not easily deformed.

Description

technical field [0001] The invention relates to a method for manufacturing laminated veneer lumber, in particular to a method for manufacturing laminated veneer lumber by using fast-growing forest materials. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, people's performance requirements for home decoration materials are becoming more and more stringent, and green, ecological and healthy wood materials are welcomed and loved by people again. my country is a country with a serious shortage of forest resources, and the forest resources are very poor. According to the results of the seventh forest resource inventory in my country, the per capita forest area in my country is less than a quarter of the world's per capita share. In addition, the "natural forest protection project" The implementation of the policy has further exacerbated the shortage of timber resources in my country. In ...

AI Technical Summary

Problems solved by technology

[0005] 1. In the preparation of the veneer, the veneer is peeled out of the small-diameter fast-growing wood. Due to the huge growth stress in the fast-growing wood, the unscrewed veneer is prone to defects such as warping and deformation. It is easy to cause uneven gluing, resulting in low bonding strength between veneers and waste of adhesive;

[0006] 2. When using fast-growing wood to make laminated veneer lumber, due to the shortcomings of fast-growing wood, such as easy deformation, light color, and unprotrusive surface texture, the LVL products made have problems such as poor decorative performance, unclear wood texture, and easy deformation. ;

[0007] 3. Laminated veneer lumber adopts the method of forming blanks with a single direction of texture, which has poor dimensional stability and low structural strength
