High-performance wood restructuring laminated wood and manufacturing method thereof

Abstract

The invention discloses a high-performance wood restructuring laminated wood and a manufacturing method thereof. Massive remainders, namely wood slabs, produced in wood processing are taken as raw materials to manufacture high-density high-strength laminated boards and squared timbers used for structure and decoration by wood restructuring technology; wherein the waste remainders of the wood processing are sawed, discongested and peeled and dried to form edgings with certain specifications; then the edgings are levelly paved in multilayer, and heat pressing and post treatment are carried out to manufacture laminated boards and squared timbers. The processing technological processes are as follows: sawing the remainders, namely the wood slabs of the wood processing to be edgings with certain width and length, discongesting and peeling, and drying to certain moisture content; carrying out gumming and secondary drying on the dried edgings, then paving the edgings in a concave groove to form blanks; then pushing the blanks in the concave groove to a die on a thermocompressor for heat pressing, forming blank flat squared timbers, and then trimming and sanding to manufacture the finished product.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a product and its manufacturing technology which utilizes the waste residues of wood processing (mainly solid wood, such as the processing of logs, boards, etc.) to turn them into high-performance solid wood through recombination technology . Background technique [0002] The wood processing industry is one of the pillar industries of my country's national economy. Sawn timber products in the wood processing industry are widely used in my country, and its application fields involve construction, furniture, packaging, transportation, machinery manufacturing and other aspects. At the same time, however, a large amount of residual waste - wood shavings - is produced in wood processing. In the past, these residues were mostly used for processing fiberboard, particleboard and other products. However, because these products need to crush or grind the skin, the or...

AI Technical Summary

Problems solved by technology

However, because these products need to crush or grind the skin, the original wooden structure of the skin is destroyed, so the finished products are mostly low-value-added products with high energy consumption, low strength and low performance, and the product structure is loose And the texture is soft, and the recovery of its woody feeling depends on another secondary processing and decoration treatment.

Not only the performance of the product is reduced, but also the processing technology is more complicated. On the other hand, since more than 80% of the wood-based panel products such as fiberboard and particleboard in my country use urea-formaldehyde as an adhesive that can release a large amount of formaldehyde, the formaldehyde in this fiberboard and particleboard The pollution of the living environment has attracted more and more attention
