Production method for arc-shaped unequal-thickness bamboo chip original-state recombined board

Abstract

The invention provides a production method for an arc-shaped unequal-thickness bamboo chip original-state recombined board. The production method comprises the following steps that protruding bamboo sheath rings on cut-off original state bamboo sections are ground off; arc-shaped bamboo chips with the widths of the two sides being unequal and the thicknesses of the two ends being unequal are prepared; after boiling, steaming and drying are conducted on the bamboo chips, a grinding machine is utilized for removing green and yellow parts on the surfaces of the bamboo chips, and then arc-shaped bamboo chips with the widths of the two sides being equal and the thickness of the two ends unequal are prepared; and the bamboo chips are coated with hot melt glue or cold mucilage glue correspondingly, the bamboo chips with the thick ends and the thin ends stacked alternately are placed on a platform to form a board blank, and the bamboo chips are hot-pressed or cold-pressed into the arc-shaped unequal-thickness bamboo chip original-state recombined board. According to the arc-shaped unequal-thickness bamboo chip original-state recombined board produced through the production method, the use ratio of the bamboo chips is increased by 30-50%, the length of the arc-shaped unequal-thickness bamboo chip original-state recombined board can be increased to 2500-3100 cm.

Description

Technical field: [0001] The invention belongs to the field of new materials, in particular to a production method of curved original recombined boards of bamboo sheets of unequal thickness. Background technique: [0002] The thickness of the bamboo walls at both ends of the original bamboo material is quite different. At present, the production of recombined bamboo boards is mostly made of original bamboo with a length of 2 meters and processed into rectangular or arc-shaped bamboo pieces with equal width on both sides and equal thickness at both ends. Hot-melt adhesives are stacked in parallel and hot-pressed into panels. There are rectangular or arc-shaped bamboo slices. When cutting green and yellow to equal thickness, the cutting waste of thick-walled sections is serious, the utilization rate of bamboo is low, and the length of restructured panels is limited. The high deficiency of production cost; the technical route of the present invention is to grind the bamboo slice...

[0002] The thickness of the bamboo walls at both ends of the original bamboo material is quite different. At present, the production of recombined bamboo boards is mostly made of original bamboo with a length of 2 meters and processed into rectangular or arc-shaped bamboo pieces with equal width on both sides and equal thickness at both ends. Hot-melt adhesives are stacked in parallel and hot-pressed into panels. There are rectangular or arc-shaped bamboo slices. When cutting green and yellow to equal thickness, the cutting waste of thick-walled sections is serious, the utilization rate of bamboo is low, and the length of restructured panels is limited. The high deficiency of production cost; the technical route of the present invention is to grind the bamboo slices into arc-shaped bamboo sheets with equal width on both sides and unequal thickness at both ends according to the original state of bamboo, and coat hot melt glue or cold glue on the bamboo sheets. Glue, thin and thick ends are staggered and stacked on the platform to form a slab, which is hot-pressed or cold-pressed into a plate; the bamboo sheets of different thicknesses produced by this production method are recombined in the original state, and the utilization rate of bamboo is increased by 30%- 50%, unequal thickness bamboo sheet curved original restructured sheet length can grow to 2500cm-3100cm
