Problems solved by technology

Due to the strong pressure of the upper oil cylinder, the bamboo is formed in the inner mold and the inner mold and the outer mold are in close contact. When the mold is released, the ejection force of the lower oil cylinder must be large to overcome the friction between the inner and outer molds, which consumes a lot of energy. And it is easy to damage the inner mold and the bamboo inside
The mechanism for fixing the outer mold must also be made strong enough, and the manufacturing cost is high

Embodiment Construction

[0034] Process flow of the present invention is as follows:

[0035] 1. Process the bamboo into 0.4-2m long, 1.4-2.4cm wide, and 1.2-2mm thick bamboo slices, remove the green layer of 0.8-1mm, and remove the dead yellow to make the product free of wax and sugar, and reach the final product The adhesion is tight without peeling off. The bamboo slices are classified and combined, and enter the next process respectively.

[0036] 2. Use a silk mill to grind the bamboo slices into vertically and horizontally connected bamboo shreds, so that the bamboo slices have gaps, so that the glue can penetrate evenly and bond tightly.

[0037] 3. Disinfect, desugar, degrease, and soften, use 2-5% hydrogen peroxide, 2-3% baking soda, 3-8% bleaching powder, 2-3% sulfite fish oil, and the rest as water to make softener. Put it into a softener, boil it in water for 1-2 hours at a temperature of 80-100°C, make the fibrous tissue expand and eliminate internal stress, remove fat, oil, and sterili...

Abstract

The present invention is production process of high density charred bamboo material, and solves the problems of high pressure made shaped material in inner stress, hardness, strength, color and power consumption. The production process includes the following steps: 1. making bamboo sheet without outmost layer and inside yellow layer; 2. cutting or rolling bamboo sheet; 3. charring inside charring tank at the pressure of 2-3 MPa and temperature of 100-300 deg.c for 2-3 hr; 4. soaking the charred bamboo material in glue; and 5. molding in mold at high pressure to cure and form. The high density charred bamboo material may be used in producing bamboo board or strip.

Description

Technical field: [0001] The invention relates to a method for processing bamboo into composite profiles. Background technique: [0002] The existing method of processing bamboo into composite profiles is as described in Chinese Patent No. 99117809.2. Moso bamboo is split into bamboo threads, dried and dipped into molds, and then solidified after 10-100MPa high pressure. The gum content is 6%-15%. Since the pressure of compression molding is generally above 50MPa, the internal stress generated by the profile is large, which affects the adhesive force and dimensional stability of the glue. Since the bamboo filaments are randomly filled in the mould, they are not classified according to the location and growth period of the bamboo, and its hardness, strength, and color are uneven, which affects the quality of the product, and it is impossible to adjust the local process according to different raw materials in the production process to ensure The hardness and color of the prod...
