Primordial bamboo plate making process

Abstract

The primordial bamboo plate making process includes the following steps: cutting bamboo into bamboo tube, cutting into arced bamboo strip, cutting the inside of bamboo strip to form stress releasing slots, crushing bamboo branches and leave into bamboo powder, heat treatment of the bamboo strip and bamboo powder, flattening the bamboo strip, filling the bamboo powder into cracks in the bamboo strip, cooling and pressing into bamboo plate. The process has the natural structure and grains of bamboo maintained and high material utilization rate, and the primordial bamboo plate has high hardness.

Description

technical field [0001] The invention relates to a method for processing bamboo into a bamboo board. Background technique [0002] Traditional bamboo boards are made by cutting, cutting into small pieces, and then bonding and pressing. The utilization rate of bamboo in this process is less than 60%. There is also a Chinese patent application 200610021013.2 disclosing a "processing method of carbonized high-density bamboo", which processes bamboo into bamboo slices, removes the green layer and dead yellow layer, and splits the bamboo slices into bamboo threads or grinds them into vertically and horizontally connected bamboo strips. Shredded bamboo flakes or bamboo shreds are placed in a carbonization tank, under the pressure of 2-3Mpa, thermally decomposed and carbonized at 100-300°C for 2-3 hours, and the pyrolytic carbonized bamboo shreds or bamboo shreds are dipped in glue, Then the dipped bamboo shreds or bamboo shreds are cured into molding materials after being subjecte...
