Problems solved by technology

[0003] With the increase in the use of beech, a lot of beech leftovers, shavings, waste wood chips, etc. are produced in the process of processing. Because the value of beech is relatively high, these wastes are also very valuable resources. The beech waste is directly discarded, landfilled as fertilizer or burned as industrial fuel. According to the analysis, the utilization rate of beech waste is not high when burned, the heat of combustion is not ideal, and resources are wasted. At the same time, the smoke generated by combustion will polluted environment

Abstract

The invention discloses a method for recycling beech waste wood chips. The method comprises the following steps that the beech waste wood chips are produced into a decorative board after being collected; (1), the following raw materials of the beech waste wood chips, epoxy resin, 2,000-mesh quartz powder, 800-mesh quartz powder, 40-mesh quartz sand, salicylate, nano zinc oxide, a coupling agent and a curing agent are weighed; (2), the raw materials are evenly mixed; (3), the mixture is loaded into a mold, and vibrating and pressing forming are carried out; (4), curing is carried out; and (5),grinding and polishing are carried out. By the adoption of the method, the beech waste wood chips can be recycled, resources are fully used, and the produced decorative board has the beneficial effects of being high in practicability, durable in use, high in anti-aging capability, good in toughness, good in sound insulation effect and the like and has the natural feeling of logs and good appearance.

Description

technical field [0001] The invention relates to a method for recycling wood chips, in particular to a method for recycling waste beech wood chips. Background technique [0002] Beech, also written as "椐木" or "椇木", is produced in the south of my country. The north does not know this name, but calls this wood South Elm. Although it is not a luxurious wood, it is widely used in traditional Ming and Qing furniture, especially in folk. This kind of beech furniture is mostly Ming style, and its shape and production techniques are basically the same as those of hardwood furniture such as huanghuali. It has considerable artistic and historical value. Beech wood is heavy, strong, impact-resistant, easy to bend under steam, clear texture, uniform wood texture, soft and smooth tones, can be made into shapes, and has good nail holding performance. The hardness of beech wood is strong, comparable to mahogany. The reason why beech wood is called "declining nobleman" is that after beech ...
