Problems solved by technology
The strength of the regenerated wood produced by these methods cannot meet the requirements for the production of various wood products, and the structure and size of the profiles cannot be set arbitrarily, which greatly restricts subsequent processing, while the quality of the produced products is low and the efficiency is low. Not high, the formaldehyde content of some adhesives seriously exceeds the standard, which cannot meet the requirements of the national standard and flow to the market, which greatly affects the health of consumers and the living environment

Embodiment Construction
[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with embodiments.
[0025] A kind of waste wood regeneration method of the present invention, comprises the following steps:
[0026] 1) Crush the waste wood to generate wood powder;
[0027] 2) Put the sawdust powder into the drying room. After the drying room is heated to 68-72°C, the hot air is circulated continuously for 90-96 hours, and the water content of the sawdust powder is controlled to be 8-13% by mass;
[0028] In the present invention, the hot air drying treatment technology is adopted, and the drying room is designed to be 8 meters long, 6 meters wide, and 3.8 meters high. The top is used for diversion and dehumidification, and the bottom and surroundings are designed with ventilation and isolation devices to circulate the hot air; PLC full braking is adopted. Con...

The invention discloses a waste timber regeneration method. Waste timber is recycled and reused by carrying out the techniques of crushing, proportioning, compression molding and cooling solidification on waste timber, and section bars can be subjected to compression-injection molding in different shapes and sizes according to needs; wood fiber, soil and wood adhesive powder are completely mixed, are breakage-proof and deformation-resistant, and products after compression-injection molding have good physical mechanical property, the strength of the products is increased by 2-3 times, compared with that of wood of products in the prior art, besides, the products after compression-injection molding have stronger plasticity, durability, and attractive, exquisite and elegant appearance.
Description
technical field [0001] The invention relates to the field of wood recycling, in particular to a method for regenerating waste wood. Background technique [0002] For a long time, the wood and wood-based panel industry has used wood and wooden materials as raw materials, with the help of continuously improving technology and mechanical and electronic equipment for production, operation and development. Because wood has the characteristics of light weight, beautiful texture, easy machining, and is a renewable resource, it is deeply loved by people and has become one of the most widely used materials. In an industrialized society, the timber industry has played a major role in the economic construction of many countries, including my country, and brought direct economic benefits to the development of the local economy and market. But at the same time, excessive use, deforestation, land reclamation, and cutting without building have severely damaged forest resources. In some pl...
