Problems solved by technology

However, fast-growing and high-yielding woods such as pine, fir, poplar, paulownia, and eucalyptus have the disadvantages of soft materials due to the short growth period and the physical characteristics of the tree species, so they are limited in use.

example 1

[0010] Example 1. The artificial fast-growing paulownia logs were sawed and disintegrated into 1000×120×30 (mm) slabs, and then put into a clear water pool and soaked until the moisture content reached 100%.

[0011] Then, the slabstock is put into a closed container for high-temperature cooking, degreasing and softened, and then pre-dried to a moisture content of less than 30%.

[0012] Then put the pre-dried board material into the hot press for heating and compression, so that the board material is gradually dried and densified. According to the technical requirements of the material, the board material is dried to a moisture content of 12% and densified to a compression ratio. 30%, then turn off the hot steam, and inject cooling water into the hot pressing plate, so that the plate material is cooled and shaped.

[0013] Finally, unload the shaped board material from the hot press, apply waterproofing agent on the four sides and both sides of the board material, stack it ne...

example 2

[0014] Example 2. The artificial fast-growing fir logs were sawn and disintegrated into 2000×100×25 (mm) boards, and then put into a clear water pool and soaked until the moisture content reached 90%.

[0015] Then, the wood board is put into an airtight container for high-temperature cooking, degreasing and softened, and then pre-dried to a moisture content of less than 30%.

[0016] Then put the pre-dried wooden board into the hot press for heating and compression, so that the wooden board is gradually dried and densified. According to the technical requirements of the material, the wooden board is dried to a moisture content of 10% and densified to a compression rate of 40%, and then closed. Hot steam injects cooling water into the hot pressing plate to cool the wood and shape it.

[0017] Finally, unload the shaped board from the hot press, apply a waterproofing agent on the sides and both sides of the board, stack it neatly, regain moisture for ten days, and confirm that ...

example 3

[0018] Example 3. The artificial fast-growing pine logs were sawed into 2000×80×20 (mm) boards, and then put into a clear water pool to soak until the moisture content reached 80%.

[0019] Then, the wood board is put into an airtight container for high-temperature cooking, degreasing and softened, and then pre-dried to a moisture content of less than 30%.

[0020] Then put the pre-dried wooden board into the hot press for heating and compression, so that the wooden board is gradually dried and densified. According to the technical requirements of the material, the wooden board is dried to a moisture content of 15% and densified to a compression rate of 20%, and then closed. Hot steam injects cooling water into the hot pressing plate to cool the wood and shape it.

[0021] Finally, unload the shaped board from the hot press, apply waterproofing agent on the four sides and both sides of the board, stack it neatly, and regain moisture for seven days. After confirming that the in...

Abstract

The invention relates to a method for manufacturing a fast-growing material through a modification process, which belongs to the technical field of forest product manufacturing. The method is characterized by adopting fast-growing timbers of an artificial forest as raw materials including low-volume-weight timbers of pine woods, cedarwoods, cotton woods, fortune paulownia wood, eucalyptus and the like. The method comprises the following steps: first sawing the fast-growing material into board square materials with the required specifications; and then performing the technical skills of soaking, cooking, pre-drying, hot pressing, cooling, shaping, dampening and the like. The modified board square materials produced by the manufacturing method are applied to manufacturing solid wood products of wooden floors, wooden furniture and the like, and the products are comparable with the products produced from natural broad-leaved trees no mater on technical targets or on functional targets.

Description

technical field [0001] The invention relates to a preparation method of an artificial fast-growing wood modification process. Background technique [0002] At present, forest products such as solid wood furniture and solid wood flooring are mainly derived from broad-leaved tree species in natural forests. With the implementation of the natural forest protection project by the state and the comprehensive ban on the logging of natural forest resources mainly composed of broad-leaved trees, the contradiction between the supply and demand of raw materials for the production of forest products has become increasingly In particular, the output of forest products such as solid wood furniture and solid wood flooring has declined year by year, while prices have risen sharply. However, fast-growing and high-yielding woods such as pine, fir, poplar, paulownia, and eucalyptus are limited in use due to the short growth period and the physical characteristics of the tree species, which de...
