A kind of whole bamboo plate unfolding method

Abstract

The invention discloses a whole bamboo board flattening method. A ripe bamboo grown naturally is taken, one to three bamboo internodes are selected, protruding parts of the bamboo internodes with bamboo joints need to be ground, bamboo inner skins and bamboo outer skins do not need to be removed, internode softening treatment is conducted, then compression treatment in the circumferential direction is conducted, the internodes are placed and taken out after being naturally aired, the compressed internodes are flattened to be in a C shape or in an arc shape and extruded into bamboo boards flattened completely, the bamboo boards are subjected to fixing treatment and taken out after being subjected to depressing drying, and the bamboo boards which are flattened completely and are not deformedare obtained. Cracking or fracturing is not liable to occur to the bamboo boards obtained through the method, the original strength and toughness of the bamboo internodes are reserved, the product quality is improved, the bamboo boards can be used for construction materials (such as floors and wallboards) and can also be used for craft materials, the application range of bamboos is enlarged, andthe additional application value of the bamboos is increased.

Description

technical field [0001] The invention relates to a method for utilizing and processing bamboo, in particular to a method for unfolding a whole bamboo plate. Background technique [0002] Bamboo generally contains several bamboo nodes, and an internode is between two bamboo nodes. Its cross-section is composed of bamboo green, bamboo flesh, and bamboo yellow from the outside to the inside. There are vascular bundles distributed on the bamboo flesh, and generally the closer to the bamboo green part, the denser the vascular distribution, and the closer to the bamboo yellow, the thinner the vascular bundle distribution. The use of bamboo in the existing market is generally: 1. Bamboo is generally used as a material for construction and handicrafts, but the utilization of cylindrical raw bamboo is very limited; 2. Most of the flat bamboo materials on the market are made of The whole round bamboo is cut into thin strips, and then glued together with an adhesive to form a flat bamb...

AI Technical Summary

Problems solved by technology

The use of bamboo in the existing market is generally: 1. Bamboo is generally used as a material for construction and handicrafts, but the utilization of cylindrical raw bamboo is very limited; 2. Most of the flat bamboo materials on the market are made of The whole round bamboo is cut into thin strips, and then glued together with an adhesive to form a flat bamboo material

Bamboo slab materials synthesized with adhesives do not highlight the advantages of bamboo natural materials, and are not approved for use in construction or handicrafts; 3. Divide the whole round bamboo that has been removed from yellow and green into two halves, or cut a slit from the whole bamboo to divide the round bamboo Become arc-shaped or C-shaped bamboo and then slowly expand into flat bamboo, but this method of flat expansion is easy to form longitudinal cracks and complete fractures, and it is difficult to obtain complete flat bamboo; 4. Some handicraft production units use very For short internode bamboo sections, most of the outer bamboo walls are removed, and the thin bamboo yellow part is unfolded, the material utilization rate is very low, and bamboo materials are wasted
