Method for processing bamboo sectional material

Abstract

The invention discloses a processing method, which can form a bamboo sectional material having rich texture, sufficiently eliminates the internal stress of bamboo chips, enhances the antiseptic property of the bamboo chips and can adjust the colour of the bamboo chip through a carbonization process at 150 to 180 DEG C. The processing method comprises the following steps: after twisting retiform bamboo chips into twist strip-shaped bamboo cables, weaving the bamboo cables into a bamboo braid; immersing the bamboo braid into a glue; and thermo-curing the bamboo braid under a high pressure to obtain a texture as a precious wood can be obtained. The number of strands and weaving methods are different, so the texture of the sectional material changes correspondingly; the original form of the bamboo is changed radically through the high pressure treatment of the process; bamboo fires are recombined into a novel bamboo sectional material; and various physical performance indexes exceeding that of the wood are obtained. The method for processing the bamboo sectional material performs precompression on the bamboo braid before thermo-curing the bamboo braid under the high pressure, which reduces the stroke of an oil cylinder of a mould press, reduces the height of equipment, saves the cost of the equipment, and improves the production efficiency. The bamboo sectional material prepared by the process method can replace the precious wood facing depletion, can be used for houses, floor boards, doors and windows and building materials, and has good market prospect.

Description

(1) Technical field: [0001] The present invention relates to a method for processing bamboo into bamboo profiles. (two) background technology: [0002] The processing method of existing carbonized high-density bamboo is described in Chinese patent 200610021013.2: [0003] The processing method of carbonized high-density bamboo comprises the following steps: (1) processing bamboo into bamboo slices, removing the green layer and dead yellow layer, (2) splitting the bamboo strands and bamboo slices into bamboo strands or grinding them into vertically and horizontally connected bamboo strands , (3) bamboo shreds or bamboo shreds are placed in a carbonization tank, under 2-3MPa pressure, pyrolytic carbonization at 100-300 ° C for 2-3 hours, (4) pyrolysis carbonized bamboo shreds or bamboo shreds Bamboo shreds dipping, (5) The soaked bamboo shreds or bamboo shreds are solidified into molding materials after high pressure in a mould. It can be used to prepare various bamboo board...

The product profile only has the straight natural lines of bamboo fiber. When the mold is under high pressure, due to the small density of bamboo filaments, the volume occupied is large, and the mold
