Wood chip recovery and reutilization process

Abstract

The invention discloses a wood chip recovery and reutilization process. The wood chip recovery and reutilization process comprises the twelve technological steps of classification according to the material texture, edge cutting and peeling, equal-length cutting, steam drying, wood shaving and flattening, gumming and splicing, mold pressing and shaping, demolding check, filling and vacancy filling,cutting and molding, tenoning and finger connecting and wood shaving and forming. The production process is simple. Wetting expansion and drying shrinkage on wood strips or line bars formed through processing are uniform, the phenomena of cracking and deformation are avoided, the performance indexes such as the air-dry density, strength and hardness are similar to those of a regular material. Reutilization of waste materials can be achieved. The utilization rate and the utilization level are high. Waste is recycled for reuse. Economical utilization of resources is achieved. The production cost can be reduced. The economic benefits can be increased. The wood chip recovery and reutilization process can be extensively used for recycling and utilization of leftover materials in the bamboo andwood processing industry.

Description

technical field [0001] The invention relates to a method for recycling broken wood, in particular to a method for processing wooden wires or lines by using broken wood. Background technique [0002] As a traditional material, wood has always been used by humans. With the changes in natural resources and human needs and the advancement of science and technology, the use of wood has gradually developed from the original log to the use of sawn timber, veneer, shavings, fibers and chemical components, forming a huge family of new wood materials. Such as cavity plywood, particleboard, fiberboard, laminated veneer lumber, glulam, recombined wood, oriented strand board, recombined decorative veneer and other wooden recombined materials, as well as gypsum particleboard, cement particleboard, wood / plastic composite materials, wood / metal composite materials, Wood based composites such as wood conductive materials and wood ceramics. As my country's economy enters a stage of steady de...

Problems solved by technology

At present, domestic wood cannot meet the growing demand in terms of quality and quantity, and it is imperative to promote wood conservation and efficient utilization

Recycling scrap wood is one of the effective ways to alleviate the domestic wood shortage, but the recycling process of leftover waste in the existing technology is immature, and the utilization rate and utilization level of leftover waste need to be improved
