Abstract

The invention discloses a production method of a heavy bamboo wide-breadth plate, and belongs to the technical field of bamboo production and processing. The method comprises the steps that moso bamboos are pretreated firstly, then phenolic resin adhesives are treated with nano-zirconia and chitosan to obtain two new adhesives, bamboo bundles are subjected to gum dipping with the two new adhesives, the obtained gum-dipped bamboo bundles are assembled, and finally cold press molding is conducted to obtain the heavy bamboo wide-breadth board. The heavy bamboo wide-breadth board prepared by the method effectively overcomes the defects that heavy bamboo products are easy to generate transverse cracks, easy to mildew and poor in stability, can well replace conventional wood to be used in the fields of furniture and the like, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of bamboo production and processing, and in particular relates to a production method of a heavy bamboo wide-width panel. Background technique [0002] my country's bamboo species, bamboo forest area and stock volume are the highest in the world. Bamboo is a fast-growing material with a short growth period. For example, moso bamboo can be harvested and used in 3-5 years. In addition, some small-diameter bamboos have a shorter growth period. Therefore, if the bamboo forest is properly managed and harvested reasonably, it will be able to provide bamboo continuously. As for precious woods such as teak, rosewood, red pine, rosewood, and wenge, it will take hundreds or even hundreds of years to become timber. Coupled with the long-term and uncontrolled cutting of human beings, some precious tree species resources have been exhausted. Therefore, the development and utilization of bamboo is a feasible way to solv...
