Process for manufacturing recombined bamboo square materials

Abstract

The invention discloses a process for manufacturing recombined bamboo square materials. The process is characterized by comprising steps of bamboo filament sheet drying, glue dipping, drying, cold press molding, solidifying, demoulding, end flattening and section forming. The moisture content of a formed section ranges from 5% to 10%. The process has the advantages that a cold press molding technique is adopted and is low in equipment investment and high in production efficiency as compared with a hot press molding technique, and a product is high in deformation resistance and is colorful; and moisture in bamboo filaments and the charge weight are scientifically matched in a cold press molding procedure, so that the quality of the finished product is further guaranteed.

Description

technical field [0001] The invention belongs to the field of board production technology, and in particular relates to a production technology method of heavy bamboo square material. Background technique [0002] Heavy bamboo, also known as recombined bamboo, is a new bamboo material that reorganizes and strengthens bamboo. The bamboo is opened into soft filaments or flakes, and the fibers are reorganized after dipping and hot pressing to change its appearance. Density, hardness and other physical and chemical properties. The density of the heavy bamboo material is 1.5 times that of bamboo before processing, and its hardness is equivalent to that of high-grade hardwood. [0003] Since the late 1980s, Nanjing Forestry University, the Institute of Wood Industry of the Chinese Academy of Forestry, Zhejiang Forestry College and Zhejiang Academy of Forestry Sciences, and some bamboo processing enterprises have conducted in-depth research on heavy bamboo from the aspects of mater...
