Description

A kind of processing method that is directed to small diameter grade bamboo wood Recombined bamboo

Technical field

The present invention relates to a kind of artificial bamboo board (material) processing technology, particularly relate to a kind of processing method that is directed to small diameter grade bamboo wood Recombined bamboo.

Background technology

The present invention relates to a kind of processing of bamboo wood, particularly relate to a kind of processing of small diameter grade bamboo wood Recombined bamboo.

China is located in world bamboo distribution center producing region, and the bamboo grove area ranks first in the world.According to statistics, 5,000,000 hectares of the existing bamboo grove gross areas in the whole nation, account for about 1/4 of world's bamboo grove gross area, bamboo has the good physiological properties such as growth cycle weak point, strong, the sustainable felling of self-germinating power, continuous utilization, abundant bamboo resource provides reliable raw material basis for the processing and utilization of China, and the bamboo processing and utilization level of China is in the first place in the world always.Since the seventies, successively developed the products such as bamboo mat plywood, bamboo weaving bamboo plywood, bamboo laminated board, bamboo plywood, bamboo floor, bamboo-wood plyboard, be widely used in the fields such as building, vehicle, packing, decoration, furniture.But, the bamboo plywood of present industrial employing, because the blue or green layer of bamboo wood is difficult for gummed, resin added is large, not environmental protection, usually adopting the mode of chipping that the green grass or young crops layer is removed during as bamboo wood people producing material, so most of utilization rate of bamboo is lower, only is 20%-40%, a large amount of residues and small diameter grade bamboo are not fully used, cause the wasting of resources, particularly cizu and so on material is little because of diameter, bending, wall is thin, be difficult for the characteristics such as processing, the utilization rate of removing blue or green afterwards material is lower, be made into the material such as bamboo plywood after cost too high again, at present mainly adopt chip rear paper feeding factory's papermaking or employing to split the thin bamboo strip to be used for bamboo plywood, the building template industry, but because its cost is high, industry existence difficulty almost can not industrialized utilization.CN1020319 discloses a kind of manufacture method of bamboo plywood, adopting the large footpath mao bamboon of diameter 〉=50 millimeter is raw material, inside and outside the past ring, subdivision, poach, wax boil, pressurize, the operations such as flattening, planing operation, dryness finalization, gluing pressing plate again, still fail to overcome the above-mentioned not enough processing problems that does not also solve small diameter grade bamboo wood Recombined bamboo simultaneously.

Summary of the invention

The object of the present invention is to provide a kind of processing method that is directed to small diameter grade bamboo wood Recombined bamboo, with overcome that prior art exists go blue or green difficulty, utilization rate of bamboo is low, production cost is high, the problem of small diameter grade bamboo processing inconvenience.

Purpose of the present invention can reach by following technical measures.It is this processing method that is directed to small diameter grade bamboo wood Recombined bamboo, mainly go the young worker to plant and the processing method of a whole set of applicable small diameter grade bamboo wood Recombined bamboo is provided with what scrape that blue or green method takes as the leading factor, comprise following eight steps, carry out as follows successively: A. adopts the circular saw off line that former bamboo is sawed-off, B. adopt the multi-disc slicer to hack sawed-off bamboo wood, C. bamboo chip is scraped blue or green the processing, D. the bamboo chip of scraping behind the green grass or young crops rolls through once rolling wheels, bamboo chip is rolled into interconnective soft bamboo chip, the bamboo chip that E. will roll is removed sugar through boiling, F. will roll, bamboo unit material after the boiling carries out drying to be processed, G. dried bamboo chip is carried out gluing, the bamboo chip of H. after with gluing carries out cold forming or hot-press gluing becomes novel Recombined bamboo.

The insider knows, in bamboo processing, for the processing of path bamboo wood, it is a difficult problem, reason is: the wall of path bamboo wood is thin, is difficult for processing, and materials processing must be removed surf green, reason is that surf green can not viscose glue, and traditional go blue or green method, as hack, go blue or green layer too much, the bamboo wood yield very little, and bamboo green layer can not well utilize, and this method adopts scrapes young worker's skill, only surf green is scraped off, such surf green just in time can be used as medicine, the huge market demand, it is per ton to sell for 4000-6000 unit, and economic benefit is obvious, and the utilization rate of bamboo wood is much higher than the mode of chipping, and production cost obviously reduces; Secondly, owing to adopt the multi-disc slicer, finish whole cylinder bamboo wood and once hack through finishing, greatly improved production efficiency, further reduced production cost; The 3rd, scrape bamboo chip behind the green grass or young crops once through the roll wheels of 4-6 group with cannelure, bamboo chip is rolled into interconnective soft bamboo chip, do not upset the bamboo fiber orientation, keep the bamboo wood fundamental characteristics.In sum, the utilization rate of its bamboo wood of recombining bamboo made from the method is high, and it is take cizu, small diameter bamboo as raw material, and raw material sources are extensive; Physical and mechanical property is good; Intensity is large, and hardness is high, hardly crooked, do not ftracture, material is even, good processability can be with common bamboo wood processing machine tool saw, plane, mortice opening, nail nail etc.; Its technique is simple, and spread is few, is the 7%-9%(solids content), good environmental protection; Required process equipment and plant area are also less, and the recombined bamboo-gluing board made from the method can be widely used as building template, carriage bottom plate, ornament materials, Jia Furniture material, floor etc.
