Processing method for homogeneous and natural texture-forming bamboo plywood

Abstract

The invention relates to method for processing bamboo plywood which is homogeneous and forms natural texture; the processing method solves the disadvantages of low productivity, bad levelness of the product surface, uneven product intensity, easy deformation, low strength and narrow application field with the present method. The method includes the following steps that saw bamboo into tubes of proper length and cleave the tubes into slices of proper width and then remove the layers of green color and yellow color; cleave the bamboo slices into thin strips of proper thickness and weave the strips in parallel with wire to form a bamboo curtain and the thickness difference of strips used for the same curtain should be within 1mm; dry and size the curtain and then dry for the second time; pile the curtain on the board of a hot-press layer by layer to form plate blank; the included angle of two neighboring layers is acute or right one and the surface layer or / and the bottom layer consist(s) of one to four bamboo curtains with included angles of zero degree between all strips in the pattern of one to four layers; the plate blank is hot pressed and trimmed to obtain the homogeneous bamboo plywood.

Description

Technical field: [0001] The present invention relates to a method of production of building materials. Background technique: [0002] The traditional bamboo plywood processing method is to saw the bamboo into sections according to the processing length requirements of the product, divide them into bamboo slices with a slicer according to the thickness of each section, remove the green and yellow of the bamboo slices, split the strips into several layers of bamboo slices, and divide the bamboo slices into several layers. Layers of bamboo slices are placed on the hot-pressed plate in the same direction after being dipped in glue to form a square blank that is cured by hot-pressing to obtain a bamboo sheet. Due to the difference in the thickness and shape of the bamboo slices, the arrangement of the inner membrane is messy and cannot be done neatly, which affects the uniformity of the density of the blank and the production efficiency. Because the bamboo fibers are arranged in...

AI Technical Summary

Problems solved by technology

Due to the difference in thickness and shape of the bamboo slices, the arrangement of the inner membrane is messy and cannot be done neatly, which affects the uniformity of the density of the blank and the production efficiency.

Because the bamboo fibers are arranged in one direction and the density is uneven, the strength of bamboo plywood is high in one direction, and the strength in other directions is significantly reduced. It can only be used as a general building material, and its surface is not smooth.
