Abstract

The primordial bamboo plate making process includes the following steps: cutting bamboo into bamboo tube, cutting into arced bamboo strip, cutting the inside of bamboo strip to form stress releasing slots, crushing bamboo branches and leave into bamboo powder, heat treatment of the bamboo strip and bamboo powder, flattening the bamboo strip, filling the bamboo powder into cracks in the bamboo strip, cooling and pressing into bamboo plate. The process has the natural structure and grains of bamboo maintained and high material utilization rate, and the primordial bamboo plate has high hardness.

Description

The preparation method of primordial bamboo plate
Technical field
The present invention relates to the preparation method that bamboo is processed into bamboo board.
Background technology
Traditional bamboo board makes by cutting, open the bonding again compacting of small pieces forms, its technology to the utilization rate of bamboo wood less than 60%.There is Chinese patent application 200610021013.2 to disclose a kind of " processing method of high density carbonized bamboo material " again, it becomes bamboo chip with bamboo processing, remove blue or green layer and inside yellow layer, bamboo chip is split into the bamboo silk or grinds the bamboo sheet that links to each other in length and breadth, bamboo sheet or bamboo silk are placed in the carbonization jar, under 2-3Mpa pressure, 100-300 ℃ of following thermal decomposition charing 2-3 hour, bamboo sheet or bamboo silk impregnation with pyrolysis charring are solidified into section bar with bamboo sheet behind the impregnation or bamboo silk again behind high pressure in mould.This bamboo board has been rejected surf green the hardest on the bamboo wood, become the original surface layer of the surface layer of section bar and former bamboo opposing simultaneously, so the hard surface layer degree of bamboo board is relatively poor, and the section bar through being solidified into behind the high pressure, the internal stress of material plate is big, and the time has been grown and will make into the section bar distortion because of the effect of internal stress.
Summary of the invention
The present invention provides a kind of utilization rate of bamboo height, surface layer hardness height just in order to overcome above-mentioned deficiency, particularly can keep the preparation method of the high-intensity ecological bamboo board of original bamboo face bamboo matter.Main innovate point is that bamboo wood must not go green grass or young crops, only do a little sanding, cutting thick bamboo tube heat treatment open flattens, make the original surface layer of bamboo wood be exactly into the surface layer of section bar, improved the surface layer hardness of bamboo board, make full use of the original performance of bamboo wood, have more ecological property, simultaneously internal stress is set and releases the slow line of rabbet joint, make into the passage that the section bar release of its internal stress has in use had science, guaranteed section bar stability in use at bamboo sirloin face.
Specifically implement like this: the preparation method of primordial bamboo plate is characterized in that being finished by the following step:
(1) preliminary treatment:
A. original bamboo wood is organized into dried, branch, leaf is standby;
B. bamboo does by barrel dliameter size, bamboo sirloin thickness classification back saw section, cuts open into the lonely shape bamboo chip of 2-6 sheet, the sheet wide region of cutting open is 1-30cm, peel off the ring of bamboo chip bamboo strip and bamboo sirloin face, and the internal stress that presets that marks one or more on lonely shape bamboo chip bamboo sirloin face is at least released the slow line of rabbet joint.But the surf green surface shows very smooth, is still keeping the original characteristics of bamboo face.Internal stress is released the quantity of the slow line of rabbet joint and decide according to the width of lonely shape bamboo chip, and width is big, and the quantity that the internal stress of offering is released the slow line of rabbet joint is just many, and internal stress is released and delayed the line of rabbet joint and evenly offer.
C. branch, leaf are rejected withered, worm and downright bad part, and well-thought-out plan silk powder is partly smashed in its growth normally.
(2) heat treatment bamboo chip and branch silk powder:
With arc bamboo chip, bamboo silk powder respectively at 80 ℃-200 ℃, the carbon gas of 1.5-3.5Mpa was depressed carbonization 2-4 hour or in 80 ℃ of-200 ℃ of following atmospheric cooking 2-4 hours.
The heat treated mode of carbonization or boiling can adopt steam, hot-air indirect, high-frequency electric wave or microwave etc., thereby makes the fiber of mao bamboon take place to soften, and then it is carried out smooth processing.
According to the difference of heat treatment type, can produce the bamboo board of different cultivars, i.e. carbonization bamboo board and natural color bamboo wood plate, the control of pressure and temperature is according to the size regulation and control of bamboo arc sheet when carbonization and boiling, and the temperature and pressure of controlling when handling bamboo silk powder is lower.
(3) compression moulding:
A. the bamboo chip constant temperature after the heat treatment is delivered on the press and flattens; Through behind the concora crush, bamboo arc sheet is launched into bamboo board, and surface layer is still former bamboo form, and surf green (part that hardness is the strongest) still exists.The hardness of bamboo board has had on original hardness further and has significantly improved after treatment like this.
B. on bamboo sirloin (bottom) face that flattens bamboo chip, in the bamboo silk powder of releasing in the natural slit of delaying the line of rabbet joint except that presetting internal stress, filling out after covering heat treatment; Like this, release the existence of the slow line of rabbet joint because of internal stress, bamboo board in use its internal stress just can obtain certain release, the stability of sheet material has just had reliable guarantee, internal stress is released the slow line of rabbet joint and can also be alleviated the punching press that sheet material is in use born in addition, keep the intrinsic toughness of bamboo wood, also increased the comfort of human body contact.
C. cold naturally back is by specification compression moulding, and dull and stereotyped surface layer is still keeping the original characteristics of bamboo, guarantees the natural profile of product perfect.
Bamboo board also can be according to actual needs, press one deck with the bamboo traditional instrument powder that synthetic resin is in harmonious proportion again at bamboo sirloin face, forms a kind of intensity height, bamboo board that internal stress is suitable.In addition, also the bamboo board of flat board as requested, can be carried out multilayer and presses again, guarantee the needed thickness of user.
Technology of the present invention can make full use of whole bamboo wood and be made into specification requirement and differ broad-spectrum bamboo board, the particularly a kind of high-intensity ecological bamboo board that can keep original bamboo face bamboo matter.The ecological bamboo board of producing, original structure of bamboo and lines have been kept, its outward appearance just as former bamboo is open and flat come, surface layer has been kept the original surface layer of bamboo wood, the bamboo board surface layer hardness that its hardness ratio traditional handicraft is made will exceed more than 10 times, raw-material utilization rate significantly improves, and can reach more than 98%.
