Problems solved by technology

However, fast-growing wood such as poplar and Chinese fir has a wide planting area and high output, and is the main raw material for the wood-based panel industry. However, this kind of wood has low density, low strength, loose material, and high swelling performance, so it cannot be directly used as building components and hardwoods. Use of raw materials for furniture and flooring
The annual production of plywood in my country is 21 million cubic meters, and a large amount of wood veneer edge strips are discarded in the production. Only 5% of the annual production of veneer edge strips is more than 1 million cubic meters, causing a lot of waste

Embodiment Construction

[0028] Below in conjunction with preferred embodiment, the specific implementation mode provided according to the present invention is described in detail as follows:

[0029] A method for manufacturing high-strength anti-corrosion glulam, the specific implementation is as follows:

[0030] (1) Material selection and preparation of veneer strips

[0031] When using the discarded wood veneer edge strips from the plywood factory, after recycling, they are manually sorted and cut by a veneer shredding machine into narrow wood veneer strips with a length of 200-1300mm, a width of ≤5mm, and a thickness of 0.5-3mm.

[0032] When poplar and fir logs are used, the wood veneer is made by the conventional rotary cutting method, and is cut and processed by a veneer shredding machine into a narrow strip of wood veneer with a length of 1300mm, a width of 3-5mm, and a thickness of 1-2mm. .

[0033] The above-mentioned narrow strips of wood veneer are dried, and the moisture content is con...

Abstract

The process of making high strength anticorrosive integrated plate material includes the following steps: forming narrow timber strip with wood leftover and low grade timber and through cutting, pressure dipping timber strip in modifying phenolic resin in solid content of 10-15 % and added preservative and serving as modifier and adhesive, stoving in a circular tunnel kiln at 90 deg.c for 30-40 min to reach water content of 12-15 %, arranging in a mold to form blank, cold pressurizing at 600-800 kg/sq m pressure, curing at 140-160 deg.c, ageing and cutting and finishing. The process is simple, and the produced plate material has density of 1-1.2, high strength, high anticorrosive performance, low cost and wide application.

Description

technical field [0001] The invention relates to a method for manufacturing a structural artificial board, in particular to a method for manufacturing a high-strength anti-corrosion integrated material. Background technique [0002] At present, in the field of wood-based panel manufacturing, the four major board types of plywood, fiberboard, particleboard and blockboard in my country are developing rapidly. According to the information, the national total output reached 4553.36 cubic meters in 2003, ranking second in the world. However, the development of structural wood-based panels is slow, and there is a shortage of products. Domestic needs depend on imports. Since structural wood-based panels are usually used as stressed components, there are high requirements for their mechanical properties, water resistance, corrosion resistance, and dimensional stability. The existing processing methods cannot meet the needs of manufacturing structural wood-based panels. [0003] my ...
