Method for manufacturing recombined integrated section by using wood in fast-growing forest

Abstract

The invention provides a method for manufacturing a recombined integrated section by using wood in fast-growing forest, which comprises the following steps of: rotatably cutting the wood in the fast-growing forest according to the requirement; carrying out carbonizing treatment, degreasing, desugarization and color on the rotatably-cut wood bark and drying; and softening the wood bark by soaking in a glue-leading activating agent, drying, flattening, binding, filling into a die, then forming at high temperature and curing at high temperature. According to the method disclosed by the invention, the wood in the fast-growing forest is used as a raw material and is subjected to rotary cutting and flattening and then is recombined into the integrated section. The method is simple; the density is uniform and easily controlled; the wood can be fully utilized so as to reduce waste; the manufactured formed section has no damage to wood grains and has the advantages of attractiveness, firmness, mildew resistance, worm damage resistance, high strength, favorable size stability, no cracking or deforming; and not any substances harmful to the body are added in the manufacturing process, and thus environment friendliness is achieved.

Description

technical field [0001] The invention belongs to the technical field of profile processing, and more specifically relates to a processing method for recombining and integrating profiles of fast-growing forest wood. Background technique [0002] With the development of society and the improvement of people's living standards, the demand for wood is increasing. Only relying on Chinese fir and pine to prepare wood is far from meeting the needs of society. At the same time, the growth cycle of Chinese fir and pine is long, and The wood is loose and can only be made into general low-end products. Cutting down a large number of pine and fir trees will have a great impact on preventing soil erosion. [0003] Fast-growing forests such as eucalyptus and poplar grow fast. Eucalyptus is the fastest growing tree in the world. During the peak growth season, it can grow 3 centimeters in a day, 1 meter in a month, and 10 meters in a year. In my country's experimental forest in Hainan, the...

Problems solved by technology

Although the profiles produced are more beautiful and can improve the utilization rate of wood, but the starch and sugar in the wood are not removed, it is easy to be infested by insects, and it is difficult to guarantee the quality of the recombined profiles during the production process

Because it pulls the wood rotary slices into filaments, although it maintains part of the longitudinal natural texture of the wood, it is still difficult to reflect the original natural texture of all the plane wood textures.

[0006] The preparation method of the recombined integrated profile disclosed above has the following deficiencies: 1. The wood has not been treated with desugar and degreasing, so the prepared recombined integrated profile is prone to moth and mildew; 2. The wood chips have not been flattened and the size Calibration and other processes, high-pressure forming is difficult to ensure the uniformity of profile density; 3. Wood chips are treated with ordinary glue, which is easy to be oxidized during use and it is difficult to avoid splitting of wood chips, resulting in deformation and cracking of profiles; 4. Loss or failure Preserves the natural texture of the wood very well
