Method for using thin-wall bamboo materials to prepare bamboo scrimbers

Abstract

The invention discloses a method for using thin-wall bamboo materials to prepare bamboo scrimbers. The method includes the steps that alkali is adopted for stewing thin-wall bamboo sheets, and then defibering, gum dipping, laying and hot pressing are carried out in sequence; NaOH is used for stewing the bamboo sheets, and the bamboo sheets are processed by lipase and then subjected to defibering,wherein by means of the procedures above, the defibering effect of bamboo bundles is obviously improved by 35% or above, bamboo green and tabasheer on the surfaces of the bamboo materials are effectively subjected to chemical erosion, the purpose of breaking wax layers and silicon layers is achieved, and the effect of improving gluing is achieved. A waste liquid generated after stewing is used fordiluting a glum liquid, and the problem of discharging the waste liquid is solved; by adopting a vacuum pressurizing dipping mode, even permeation of an adhesive in the bamboo materials is achieved,consumption of the adhesive is reduced, the production cost is reduced, efficient utilization of the thin-wall bamboo materials is achieved, and the environment is protected. The physical and chemicalstrength of the scrimbers are obviously improved, the horizontal shearing strength is improved by 25% or above, the thickness swelling rate of water absorption is reduced by 100% or above, the bending strength is improved by 20% or above, and the elasticity modulus is increased by 15% or above.

Description

technical field [0001] The invention relates to the field of wood-based panels, in particular to recombined bamboo, and more specifically to a method for preparing bamboo recombined wood from thin-walled bamboo. Background technique [0002] In recent years, my country's bamboo industry has developed rapidly, especially the research and development of recombinant bamboo products, which has played a major role in promoting the development of bamboo industry. Recombined bamboo is processed by rolling and decompressing equipment into a network of bamboo bundles that are not broken in the horizontal direction, loose in the vertical direction and interlaced without disturbing the arrangement direction of the bamboo fibers and retaining the basic characteristics of the bamboo, and then dried, sizing and A new type of wood-based panel with high strength, large format size, and natural bamboo texture structure made by hot pressing (or cold pressing) and other recombination processes...
