Laminated board formed by fine disintegration and rearrangement of whole raw bamboos and production technical method thereof

Abstract

The invention discloses a laminated board formed by the fine disintegration and rearrangement of whole raw bamboos and a production technical method thereof. Moso bamboos are used as raw materials. The method comprises the following steps that first, raw arc-shaped bamboo sheets are finely cut, disintegrated, rolled and unfolded by a machine to form longitudinal bamboo filaments, the bamboo filaments are laterally connected into planar trapezoid bamboo blocks of basically identical thickness, and the widths of the planar trapezoid bamboo blocks gradually change from one ends to the other ends; then, the wide ends and the narrow ends of two adjacent bamboo blocks are alternately put according to the width direction of the same end of one planar trapezoid bamboo block, the bamboo green sides or the bamboo yellow sides are arranged on the same upper side or the same lower side, and the bamboo blocks are glued to form a whole board, thereby forming a fine disintegrated bamboo filament block single-layer board; and at least two layers of fine disintegrated bamboo block single-layer boards are layered and laminated in a way that the bamboo green sides of two adjacent layers of single-layer boards are close or the bamboo yellow sides and the bamboo green sides in two adjacent layers are close, and the laminated board formed by the fine disintegration and rearrangement of the whole raw bamboos is obtained after different layers of single-layer boards are glued by an adhesive and hot-pressed into a whole. According to the invention, the bamboo bodies are stored to an utmost extent, a cut quantity is reduced, and the mechanical properties of the raw bamboo materials are exerted.

Description

technical field [0001] The invention belongs to the technical field of production of bamboo boards, and in particular relates to an original whole bamboo finely decomposed and recombined laminated lumber and a production process using moso bamboo as a raw material. Background technique [0002] Existing realization of the bamboo processing method of suitability for industrialized production all is by bamboo strips or bamboo rafts of certain specifications are processed into bamboo. In this way, it is necessary to remove the triangular margin of the arc-shaped bamboo block bamboo green bamboo yellow layer and both sides, and consume about 45% of the bamboo material, and there are many processing procedures, large equipment investment, large labor costs, low raw material utilization, and low energy consumption. High, high processing costs. And recently, there is a kind of high-density recombined material, which is produced by reorganizing and strengthening the bamboo material...

AI Technical Summary

Problems solved by technology

However, the bamboo slices or bamboo blocks are still milled and cut with a fixed thickness and a fixed width, which removes the thickness material and side width material margin of the bamboo material, and a certain amount of bamboo material is lost during processing, and the maximum physical stock of bamboo material is not reached.
