Utilization method of combining and renovating refuse wood

Abstract

The embodiment of the invention provides an utilization method of combining and renovating refuse wood. The utilization method comprises the following steps: processing refuse wood with high-temperature steam at 100-120 DEG C or cooking secondarily processed timbers with hydrogen peroxide or caustic soda for 0.5-3 h for degreasing treatment, drying the same, and drying the timbers soaked by resinat 30-55 DEG C, wherein the water content of the timbers is reduced to within 15%; pressing and forming the dried timbers which are finished by means of a hydraulic press; coating an adhesive to an adhesive groove of a waste wood block which is pressed and formed, wherein the dosage of the adhesive of the waste wood per meter is 10ml, combining and joining the waste wood blocks along joining seams, leaving the waste wood blocks to stand for 30-50s, continuously repeating the steps, and splicing the waste wood blocks into a wood plate; and curing the spliced and formed deformed semi-product tocure resin for 10-16h to obtain a recombined module wood product. By applying the utilization method provided by the invention, the utilization ratio of combining and renovating the refuse wood is improved, and the hardness of the renovated template is improved.

Description

technical field [0001] The invention relates to the technical field of waste wood utilization, in particular to a method for utilizing waste wood through combined renovation. Background technique [0002] At present, in the world, with the rapid development of furniture, flooring, paper and other industries, a large number of log resources are consumed, and forest resources are decreasing day by day, which not only causes great damage to forest resources, but also causes soil erosion, Environmental degradation and other issues. However, the market demand for furniture and flooring is still increasing. [0003] When using logs to produce modular wood, it is necessary to carry out a long period of aging treatment, degreasing, anti-corrosion and other pretreatments on the logs, and a lot of leftovers are produced during the processing. Most logs also have shortcomings such as cracking, deformation, water resistance, and light resistance. [0004] Waste wood boards are waste ...

AI Technical Summary

Problems solved by technology

Most logs still have defects such as cracking, deformation, water resistance, and light resistance.

[0004] Waste wood boards are waste materials produced during the cutting process of wood boards. Since the waste materials come from the leftovers after cutting processing, the lengths are different, which is not conducive to unified recycling.

A large amount of waste wood in China is processed through crushing for cheap recycling, which cannot make good use of waste wood. At the same time, the recycling price is low and the economic benefits are not high.
