The production method of thin bamboo sheet and thin bamboo decorative plate thereof
The present invention relates to the production method of the ornamental thin bamboo sheet of a kind of large format and thin bamboo sheet thereof is the bamboo decorations decorative panel that raw material is made, and belongs to the processing of timber or similar material or preservation
Technical field.
The production method of bamboo matter thin plate, bamboo plywood one again in (publication number CN1119576A) following description was once arranged: the former material of ancestor bamboo in the Meng is cut apart at circumferencial direction, before cutting apart with water boil about 1 hour → 100~150 ℃ dry 24 hours down → to cool off → cut apart the sheet material that is become naturally superimposed along the thick direction of bamboo, then under 120~150 ℃, compose glued board blank → become 2~5mm to approach (bamboo) plate → superimposed hot pressing that again the gained thin plate crossed one another with the vertical sawing of superposed surfaces and become bamboo plywood.It is used for concrete blinding, has anti-distortion action, but the method complex process, energy consumption is big, and the glued board blank of most importantly making by above-mentioned technology, owing to become dry glued board blank through high-temperature process, even the thick 2mm of sawing is above passable, but wanting slicing thickness is that the yield rate of the following thin plate of 1mm or 1mm is extremely low, no using value.
The objective of the invention is to, provide a kind of suitable large format to use, and can the slicing yield rate higher thin bamboo sheet and the thin bamboo decorative plate of making by described thin bamboo sheet thereof.
Technical scheme of the present invention is as follows:
The production method of thin plate veneer is: adopt the former bamboo of being rich in the water yield to be cut into certain-length, dissect into the wide and thick bar bamboo of regulation, again with gained bar bamboo compression set well-thought-out plan cylinder, directly slicing becomes thin bamboo sheet then.
Thin bamboo decorative plate is made of upper strata thin bamboo sheet and lower floor's base material, and its preparation method is as follows: after applying glue on the base material, the thin bamboo sheet of flat auxilliary above-mentioned gained is colded pressing and hot pressing then, large format approach bamboo decorative plate.
Compared with prior art, the present invention has following advantage:
1, use production method of the present invention, not only can dig one millimeter with interior book bamboo veneer, and the slicing yield rate improves greatly, also prolong greatly the service life of slicer planing tool, thereby reduced production cost.
2, the release of the thin bamboo decorative plate of large format provides a new ornament materials kind to market, has satisfied the people's needs.
3, production technology is simple.
4, save multiple tracks energy consumption technology in the manufacturing process, therefore saved the energy.

Below the invention will be further described:
Adopt fresh mao bamboon, and it is cut into certain-length E, for example 1250,2470mm, dissect into flat strips bamboo 1, its width 1 is 3~7mm, thickness h is 20~40mm, two wide and thick sides of bar bamboo all should be smooth, at a more flat gluing and superimposed, width after it is superimposed should reach the length L of setting, and the bar bamboo after superimposed is put into press, equally to bar bamboo 1 gluing, make its width and last equating, be that L is long, and it is overlayed first placed on the bar bamboo in the press ... so repeatedly, be added to till the height H of setting always, made it bonding in cold back one hour, when colding pressing, the moisture content in the bamboo bar is extruded a part, the glue that this moisture content runs into the bamboo face just can solidify, the bar bamboo is sticked together, and become the long E that is, wide is L, height is the bamboo cylinder 2 (Fig. 2) of H, after pressurization finishes demoulding, under the environment of humidity, place diel, purpose is to make curing more thorough, directly slicing at normal temperatures after the curing, the thickness h of slicing, it can be regulated on demand, for example 0.14~1.8mm handles through mildew-resistant again, and drying is the thin bamboo sheet finished product.
Thin bamboo sheet drying that slicing is made, thin bamboo sheet.Because the water content of former bamboo, bamboo cylinder is higher, the thin bamboo sheet of slicing is difficult for breaking, and yield rate is than original improve more than three times, uses for thin bamboo sheet and has opened up bright prospects.
If former bamboo is because of after depositing certain hour, water content is lower, but water logging or boiling make its water content and the water content of fresh former bamboo suitable.
Thin bamboo decorative plate constitutes (Fig. 2) by upper strata thin bamboo sheet 3 and lower floor's base material 5, and its preparation method is as follows:
Three-ply board with wait evenly applying glue on the base material (spray, manually be coated with, mechanism be coated with all can), resin added be every square metre 250 the gram about, again thin bamboo sheet is tiled on the base material → is put into to press on the cold prepressing machine and put 1-2 hour, to extrude air between base materials such as three-ply board and the thin bamboo sheet and unnecessary glue amount, make between three-ply board and the thin bamboo sheet and do not have bubble, reach hard close docile purpose, move on the hot press again after colding pressing, press down at 120 ℃ and to put 10 minutes, glue is solidified fully, quiet put trimming behind the certain hour, sanding the thin bamboo decorative plate 4 of large format.The length A of the thin bamboo decorative plate of large format and width B are pressed customer requirements and are decided, and generally can adopt 1220 * 2440mm.
