Abstract

The invention relates to an improved method for manufacturing a sliced bamboo decoration material. The method solves the problems that: 1, the sliced bamboo decoration material is made of short bamboo chips, and the limitation that the bamboo plate width is limited by the bamboo chip length is broken; and 2, by changing the water injection technology, the injection is faster and more uniform. The method comprises the following steps of: 1) preparing the short bamboo chips; 2) manufacturing short bamboo plates; 3) lengthening and shaping the short bamboo plates, namely tenoning, gluing, and lengthening the short bamboo plates; 4) humidifying long bamboo plates, namely placing the bamboo plates into a cold water tank for impregnating at normal pressure, impregnating radial bamboo plates for 10 to 20 days, and impregnating chordwise bamboo plates for 10 to 20 days, and performing pressurization and water injection on the impregnated long bamboo plates to ensure that the moisture content of the long bamboo plates is over 25 percent; 5) manufacturing square bamboo, namely performing air drying on the humidified long bamboo plates until the moisture content is between 30 and 45 percent, applying a wet curing adhesive between a plurality of layers, performing cold-press gluing, and naturally ageing for more than or equal to 12 hours after pressure relief; 6) softening the square bamboo; and 7) slicing.

Description

A kind of manufacture method of sliced bamboo decoration material
Technical field
The present invention relates to the manufacture field of bamboo wood, specifically is a kind of manufacture method of improved sliced bamboo decoration material.
Background technology
At present, in the manufacturing of sliced bamboo and thin bamboo decoration material, the bamboo wood of being taked generally is to get material according to the length of bamboo clappers, greatly in 2000mm~3200mm scope, because the bamboo bar exists taperingness, when making the rectangle bamboo chip, fixed thick drawing materials with bamboo wood blank microcephaly is that benchmark is processed, it is big to exist the planing amount, the problem that the bamboo timber resource waste is serious.In Chinese patent literature CN1227102C patent disclosure " a kind of sliced bamboo and production method thereof ", what it adopted is exactly the manufacture method of rectangular bamboo chip, and because of bamboo wood planing amount is big, resource utilization is not high; On the other hand, in bamboo square bar manufacture process, should carry out sanding surface or shaping processing to bamboo board in advance, impregnate impregnation process in the water cooling pond again, can utilize the resting period to improve the moisture of bamboo board like this, take out again pressurized humidification when waiting to make the bamboo square bar again and handle, thereby realize that bamboo board moisture injects fast and evenly, the slicing quality is good; At last, when the softening processing of bamboo square bar, also can adopt the softening mode of high-frequency heating, just can enhance productivity greatly.This production technology is applicable to that side is pieced together and the production of charing, true qualities or the knockdown all kinds of sliced bamboo decoration materials of concora crush.
Summary of the invention
The problem that the present invention need solve is, the one, utilize short bamboo chip to make thin bamboo decoration material, break the limitation that the bamboo board breadth is subjected to the bamboo chip length restriction, the 2nd, change water injection technology, make inject quicker more even.
The manufacture method of the thin ornament materials of slicing of the present invention is characterized in that as follows:
1) lacks the bamboo chip preparation: get 0.6 ~ 1.3m and (be preferably the short bamboo section of 0.9 ~ 1.3m) length, vertically saw or cut open into thick bamboo sheet, its four sides (make the tolerance of the width of bamboo chip and thickness be controlled at ± 0.1mm scope in) of planing, through boiling, drying or charing, adjustable cast iron planes becomes true qualities or the short bamboo chip of charing;
2) lack the bamboo board manufacturing: true qualities or the short bamboo chip of charing are carried out gluing, after concora crush or side pressure, make tangential or radially short bamboo board respectively;
3) lack bamboo clappers spreading-shaping: the short bamboo board that will make, carry out mortise, applying glue, spreading to Len req at an end or the two ends of its plate length direction, long bamboo board is carried out surface planing shaping handle; The tenon of being opened can be a side tooth profile, is preferably zigzag, and space width is 6 ~ 12mm, facewidth 0.9-1.8mm, and tooth length is 10 ~ 15mm.
4) long bamboo board humidification: will long bamboo board put into and carry out the normal pressure dipping in the water cooling pond, wherein through the radially bamboo clappers dipping of side pressure 10 ~ 20 days, through the tangential bamboo clappers dipping of concora crush 15 ~ 25 days; Long bamboo board behind dipping is pressure water injection again, and pressure is 0.3 ~ 0.8MPa, and the time is 6 ~ 24h, makes the inside and outside moisture content of long bamboo board even, and moisture content reaches more than 35%, gets the long bamboo board of humidification;
5) the bamboo square bar is made: the long bamboo board of humidification is air-dry, to bamboo clappers surface moisture content 30 ~ 45%, be applied with commercially available wet solid type adhesive between the long bamboo board of several layers humidification, and the gummed of colding pressing is made wet bamboo square bar; Naturally display after the release 〉=12h; The pressure of colding pressing is 1.2 ~ 3.0MPa, and the time is 1.5 ~ 3.0h;
6) the bamboo square bar is softening: step 5) bamboo square bar adopts hot water or the softening mode of high-frequency heating to carry out; When hot water softened, programming rate was controlled at 1.5 ~ 2 ℃/h, 35 ~ 70 ℃ of temperature, softening time 24 ~ 72h; When high-frequency heating was softened, programming rate was controlled at 0.5 ~ 2 ℃/min, and temperature is controlled at 35 ~ 70 ℃, softening time 0.5 ~ 2h;
7) slicing must approach bamboo decoration material.
Adopt short bamboo chip spreading to make the lengthy motion picture sliced bamboo, can significantly reduce bamboo wood planing amount, improve the bamboo timber resource utilization rate, this is first improvement of the present invention; In addition, after carrying out sanding surface or shaping processing after the bamboo board manufacturing, impregnate in advance and soaking the processing that stagnates in the water cooling pond, can utilize the resting period to improve the moisture of bamboo board like this, carry out the pressurized humidification processing by the time take out again in the time of will making the bamboo square bar, thereby realize bamboo board moisture purpose even and that inject fast, the slicing quality is good, and (sliced bamboo thickness is 0.10 ~ 2.00mm), and this is that another point of the present invention improves; At last, also can adopt the softening mode of high-frequency heating when the softening processing of bamboo square bar, can realize bamboo square bar fast softening, the purpose of protection environment can improve production efficiency greatly.
The sliced bamboo sheet can directly be used as product; Also can be by follow-up assembly wide or spreading make the large format sliced bamboo; Can also scribble glue-line and process layer, wherein process layer can be flexible materials such as harmless paper, cloth, or other sheet material, and the process for coating layer has the sliced bamboo of preventing cracking, gains in strength and be convenient to effects such as processing.
