Abstract
The invention relates to a method for manufacturing a modified process of artificial fast-growing wood, which belongs to the technical field of forest product manufacture and is characterized in that: the fast-growing wood for artificial forestation is used as a raw material and comprises low-volume-weight wood such as pine, fir, poplar, tung, eucalyptus and the like. Sawing fast growing wood into square plate material of required specification, soaking, steaming, predrying, hot pressing, cooling, shaping, moisture regaining and other technological processes. The modified square board produced by the method is used for manufacturing solid wood products such as wood floors, wood furniture and the like, and can be comparable to products produced by natural broad-leaved trees in technical indexes and functional indexes.
Description
Technical field
The present invention relates to a kind of preparation method of artificial fast growing wood modified technique.
Background technology
At present; forestry products such as solid wood furniture, the solid wooden floor board deciduous species in the wildwood that mainly have drawn from; along with country implements wildwood protected project; prohibited since the wildwood resource of cutting down based on broad leaf tree comprehensively; the raw material imbalance between supply and demand of production forest product becomes increasingly conspicuous; forestry products such as solid wood furniture, solid wooden floor board output descends year by year, and price is unprecedented soaring.And pine, China fir, poplar, paulownia wood, eucalyptus constant speed give birth to high yield timber, and reasons such as physical characteristic short owing to growth year and seeds have determined the soft shortcoming of itself material, have been subjected to certain limitation on purposes.Exploitation is made forestry products through the artificial fast growing wood of modification; widen the processing and utilization approach of fast growing wood; come progressively to substitute the product of producing with the wildwood resource with the artificial fast growing wood product; for protection wildwood resource; improve China's ecological environment, realize that forest resource sustainable development is significant.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of preparation method of the fast-growing material through modification process that can compare favourably with the product that the wildwood resource is produced is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of preparation method of fast-growing material through modification process, it is characterized in that at first the artificial fast growing wood log saw being separated into the plate square stock of required specification, then drop into and be dipped to moisture content in the clear water reserviors and reach more than 80%.
After the plate square stock packed into carry out thermophilic digestion in the closed container, after degreasing is softening, carry out pre-dry-cure to moisture content below 30%.
Again the plate square stock after the predry is put into and heated compression on the hot press, make progressively dry closeization of plate square stock, according to specification requirement with material, with the plate square stock be dried to moisture content be 8%～16% and closeization to compression ratio be 20%～50%, close vapours subsequently, in heating platen, inject cooling water, make plate square stock cooling and shaping.
Plate square stock with typing draws off from hot press at last, around the plate square stock and the two sides be coated with and spread waterproofing agent, stack neatly, get damp again more than the week, and after the elimination of the internal stress of definite plate square stock, can make timber products.
Fast-growing material through modification process technology provided by the invention, the one, expanded the use channel of low unit weight timber; The 2nd, can save a large amount of wildwood resource and cost of material; The 3rd, reduced effectively to produce and polluted, protected ecological environment.
The plate square stock of producing with fast-growing material through modification process of the present invention, purposes is very extensive, can replace wildwood timber fully and produce forestry products such as solid wood furniture, solid wooden floor board, because fast-growing material through modification process has improved the density of timber, therefore, no matter in technical indicator or on functional parameter, all can compare favourably with the product that natural deciduous species are produced.
The specific embodiment
Example one. artificial fast growing wood paulownia log saw is separated into the plate square stock of 1000 * 120 * 30 (mm), then drop into and be dipped to moisture content in the clear water reserviors and reach 100%.
After the plate square stock packed into carry out thermophilic digestion in the closed container, after degreasing is softening, carry out pre-dry-cure to moisture content below 30%.
Again the plate square stock after the predry is put into and heated compression on the hot press, make progressively dry closeization of plate square stock, according to specification requirement with material, with the plate square stock be dried to moisture content be 12% and closeization to compression ratio be 30%, close vapours subsequently, in heating platen, inject cooling water, make plate square stock cooling and shaping.
Plate square stock with typing draws off from hot press at last, around the plate square stock and the two sides be coated with and spread waterproofing agent, stack neatly, got damp again 15 days, and after the elimination of the internal stress of definite plate square stock, can make timber products.
Example two. artificial fast growing wood China fir log saw is separated into the plank of 2000 * 100 * 25 (mm), then drop into and be dipped to moisture content in the clear water reserviors and reach 90%.
After plank packed into carry out thermophilic digestion in the closed container, after degreasing is softening, carry out pre-dry-cure to moisture content below 30%.
Again the plank after the predry is put into and heated compression on the hot press, make progressively dry closeization of plank, according to specification requirement with material, with plank be dried to moisture content be 10% and closeization to compression ratio be 40%, close vapours subsequently, in heating platen, inject cooling water, make the plank cooling and shaping.
Plank with typing draws off from hot press at last, around plank and the two sides be coated with and spread waterproofing agent. stack neatly, got damp again ten days, and after the elimination of the internal stress of definite plank, can make timber products.
Example three. artificial fast growing wood Songyuan City wood saw is separated into the plank of 2000 * 80 * 20 (mm), then drop into and be dipped to moisture content in the clear water reserviors and reach 80%.
After plank packed into carry out thermophilic digestion in the closed container, after degreasing is softening, carry out pre-dry-cure to moisture content below 30%.
Again the plank after the predry is put into and heated compression on the hot press, make progressively dry closeization of plank, according to specification requirement with material, with plank be dried to moisture content be 15% and closeization to compression ratio be 20%, close vapours subsequently, in heating platen, inject cooling water, make the plank cooling and shaping.
Plank with typing draws off from hot press at last, around plank and the two sides be coated with and spread waterproofing agent, stack neatly, got damp again seven days, and after the elimination of the internal stress of definite plank, can make timber products.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
