Problems solved by technology

This method improves the utilization rate of bamboo, and the stability of the profile is good, but there are following defects: 1) the raw material is generally all bamboo, and the material is too single, and the raw material supply is relatively tight; 2) when moso bamboo is made into bamboo silk, a large amount of bamboo will be produced The waste materials, including dust, particles, fragments and broken wires, reduce the utilization rate of raw materials; 3) the bamboo fiber structure is damaged to a large extent by the wire drawing method, and a large amount of glue is used in the reorganization process. The cost is high and the density (specific gravity) of the profile is increased

Embodiment Construction

[0013] As shown in the figure, the manufacturing process of bamboo-wood composite profiles is as follows:

[0014] Raw material processing: Saw the bamboo and wood according to the specifications, then remove the green of the bamboo and peel the wood.

[0015] Rolling: Press the raw materials into blanks with unequal cracks, the thickness is 2-5mm, the width is 2-30mm, and the length is optional.

[0016] Blank heat treatment, drying, gluing, and aging: Heat treatment is to soak the blank in a hot water pool or pass it through steam to achieve the purpose of softening, anticorrosion, and mildew resistance. When drying, the moisture content is controlled at 8-10%. The rubber material is modified phenolic glue, and the glue content of the blank is controlled at 3.5-4.5%. Aging means that the glued raw materials are left for a period of time to make the glue more uniform in the material.

[0017] Blank assembly: Bamboo-wood composite integrated blank assembly, the upper and lowe...

Abstract

The present invention is timber and bamboo material processing and utilizing method. The present invention features that the timber-bamboo section bar is produced through the following steps: eliminating green part of bamboo, eliminating bark of timber, mechanically rolling into bamboo and timber sheet with glue content of 3-5 %, heat treatment, drying, gluing, ageing, compounding and molding and high temperature hot pressing to solidify and to form the section bar. The present invention well combines timber and bamboo material, and has less damage to their fiber structure and low glue consumption.

Description

technical field [0001] The invention relates to a method for processing and utilizing bamboo and wood. Background technique [0002] There are many methods for simply processing wood or bamboo. The Chinese invention patent No. 99117809.2 discloses a method for recombining bamboo to strengthen molding materials. Pressed under high pressure and cured into shape. This method improves the utilization rate of bamboo, and the stability of the profile is good, but there are following defects: 1) the raw material is generally all bamboo, and the material is too single, and the raw material supply is relatively tight; 2) when moso bamboo is made into bamboo silk, a large amount of bamboo will be produced The waste materials, including dust, particles, fragments and broken wires, reduce the utilization rate of raw materials; 3) the bamboo fiber structure is damaged to a large extent by the wire drawing method, and a large amount of glue is used in the reorgani...
