Description
Technical field
The present invention relates to a kind of highly effective continuous fissureless flattening method of bamboo wood, the bamboo wood belonged in timber industry adds
Work technical field.
Background technology
The bamboo resource in China enriches, and the bamboo grove area of 2011 is 538.1 ten thousand hectares and 16.44 hundred million bamboo woods.These
Develop bamboo processing for China and provide sustainable raw material, Bamboo flattening is because its raw material sources is sustainable and utilization rate
High, beautiful texture, but the existing Bamboo flattening high-temperature steam very high in pressure also in need（Such as 180 DEG C）It is middle to carry out, it is necessary to special
Boiler processed is, it is necessary to which the compressive resistance of pressurized tank is also higher (needing minimum 1.8MPa).This is primarily due to it and handled in high-temperature tank,
Then thick bamboo tube in tank is taken again in the cold environment in workshop and flattened, because the temperature in its workshop only has 10~30 DEG C, heated bamboo
Cylinder cools down soon, and the caused Surface hardened layer that scatters and disappears of thick bamboo tube moisture after high-temperature process, so can only be by its temperature
Degree is heated to more than 180 DEG C, could meet that thick bamboo tube can also be kept more than bamboo wood softening point under cold workshop condition.For this to existing
Some Bamboo flattening production technologies are improved, and thick bamboo tube passes through 140~160 DEG C of superheated steams in the continuous pipe of separation
Heating, and being heated at high temperature in follow-up one end keeping warmth space, by its by the nip rolls that broadens step by step successively by more thick bamboo tubes or
The bamboo chip of certain radian is flattened and cooled sizing.
Existing round thick bamboo tube production technology can be improved using this technique, using bamboo wood in the case of high humidity, it softens
The characteristic that point temperature can reduce, when reaching bamboo wood softening point, by circle Bamboo flattening in the space of insulation, meanwhile, it can carry again
The production efficiency and quality of height circle thick bamboo tube, because the material containing lignin, cellulose and hemicellulose, in high temperature 180
In the case of DEG C, the fast degradation of hemicellulose easily occurs, not only reduces the mechanical property of sheet material, while its material is also changed into brown
Color, the quality and aesthetic of flattening bamboo chip are reduced, while is operated at high temperature without worker, will the defects of the cracking of finished product
Substantially improve.
The content of the invention
Proposed by the present invention is a kind of highly effective continuous fissureless flattening method of bamboo wood, and its purpose is intended to utilize fresh bamboo
Cylinder the quick heating and damp and hot heat treatment of high-temperature steam, makes bamboo in the high temperature super heated steam pipeline that temperature is 130~160 DEG C
Cylinder water conservation heating, is rapidly reached the softening point of lignin, cellulose and hemicellulose, and is being heated at high temperature in a follow-up end spaces,
The thick bamboo tube that more have been open by it successively by the flattening equipment for the milling roller that broadens step by step or cambered bamboo chip flattening and it is cold
But shape.
So make it that the flattening of circle thick bamboo tube is flattened when not including too high 130~160 DEG C of temperature.Reduce bamboo flattening
Treatment temperature, required pressure pan during without heating, and adverse circumstances when mitigating operation, and it is more due to having on pipeline
Individual hermatic door, the heating space of different temperatures can be divided into, and thermal source can recycle, energy consumption is low.So at flattening
Reason, physical and mechanical property etc. of the flattening bamboo wood of manufacture is more preferably, and in beautiful color, is adapted to manufacturing process product, furniture and household dress
Repair use.
The technical solution of the present invention：A kind of highly effective continuous free from flaw flattening method of bamboo wood, it is characterized in that including
Following processing step：
（1）New fresh bamboo tube pretreatment；
（2）Thick bamboo tube, which enters in heating pipe, to be heated；
（3）Thick bamboo tube flattens in the keeping warmth space for heating pipe of ining succession；
（4）Flatten the post processing of bamboo chip.
Advantages of the present invention：
1）The present invention by physical and mechanical property of flattening bamboo of manufacture etc. more preferably, it is and in beautiful color, be adapted to manufacturing process product,
Furniture and house fitting-up use.
2）Flattening bamboo can also be such that a utilization rate of the big footpath bamboo wood such as mao bamboon is improved from 20%~50% to more than 85%, together
When, it will justify Bamboo flattening in continuous lines heating and flattening, the production efficiency and quality of round thick bamboo tube can be improved again.Because contain
There is the material of lignin, cellulose and hemicellulose, in the case of 180 DEG C of high temperature, the fast hydrolyzing of hemicellulose easily occur,
The mechanical property of sheet material is not only reduced, while its material is also changed into brown, reduces the quality and aesthetic of flattening bamboo chip, simultaneously
Mitigate the intensity that worker operates flattening at high temperature, production automation degree is high, and finished product need not remove blue or green processing, the cracking of finished product
The defects of will substantially improve.Make it possible the large-scale production of flattening bamboo, also provided safeguard for the sound development of bamboo industry.
3）It may be such that the flattening of round thick bamboo tube is flattened when not including too high 130~160 DEG C of temperature.Reduce bamboo flattening
Treatment temperature, required pressure pan during without heating, and adverse circumstances when mitigating operation, and it is more due to having on pipeline
Individual hermatic door, the heating space of different temperatures can be divided into, and thermal source can recycle, energy consumption is low.
