Bamboo fiber bundles recombination single-plate and production method thereof

Abstract

Disclosed is a bamboo fiber bundle reconstructed veneer and a producing method thereof, which relates to a bamboo plate. The veneer is glued by the bamboo fiber bundle which is processed by making bamboo into fiber bundle loosing surface with interlaced connection and maintaining the an original fiber arraying direction. The thickness of the veneer is 0.1mm to 2mm, the producing method of the veneer includes the steps that the bamboo prepared to be glued is dried and dipped, the material is paved, the bamboo is arranged in a press, and the pressing and curing process is performed; the method is characterized in that the bamboo prepared to be glued is first made into fiber bundle before the drying process, the plate after being pressed and cured is softened, then is sliced or peeled into a 0.1mm to 2mm veneer through veneer slicer. The veneer has the advantages that the seeped adhesive quantity is high and uniform, and the density is high; the drying shrinkage variable and the humidity expansion variable of the veneer are low after the veneer is sliced or peeled, the veneer is uniform, the cracking is not easy, the quality of the plate is improved a grade, and the appearance decorativeness of the veneer is optimized. The large and small bamboo all can be utilized, the process is simple, the efficiency is high, and the scale production is favorable.

Description

Technical field: [0001] The present invention relates to a board for bamboo products. Background technique: [0002] Chinese patent 00127973.4 "a production method of bamboo veneer" and 01120942.9 "production process of thin bamboo veneer" disclose the production method of bamboo veneer. Then it is sliced ​​or rotary cut into veneers with a thickness of 0.15-4MM by a planer. The glued raw materials of this method require cutting the bamboo slices with the same growth, width and thickness before entering the glueing stage. The selected bamboo raw materials The requirements are high, and at the same time, the waste of cutting edge materials is large, and the efficiency is low, which is not conducive to large-scale production. Secondly, after the bamboo slices are laminated, dipped in glue and pressed into wood, the penetration of the glue into the bamboo slices is generally only on the surface, and the intermediate bamboo slices cannot penetrate. That is to say, when the vene...

[0004] Secondly, this kind of veneer has uneven density, and there will be another effect in the dry shrinkage and wet expansion reaction, that is, the dry shrinkage and wet expansion reaction amount is different at the uneven density, that is, the deformation amount is different, and the different deformation amount will make the thin plate curved, uneven

[0005] Gluing bamboo slices as a thick board has not yet shown its shortcomings, but when sliced ​​or rotary cut into veneers, the sliced ​​or rotary cut surface may be all or part of the interface between bamboo slices and bamboo slices. The surface of the veneer has some bamboo patterns and some glue spots on the surface, and the overall appearance is disfigured. This veneer must be eliminated, resulting in waste
