Embodiment 1

[0020] A kind of production method of bamboo plywood for building, comprises the following steps:

[0021] (1) get fresh bamboo, remove the green bamboo on the surface of the fresh bamboo, then cut the original bamboo into 3-5 pieces, remove the yellow bamboo of the fresh bamboo inner layer and the diaphragm part of the bamboo joint after dissection;

[0022] (2) bamboo chips are pressed by a roller press to make bamboo chips become bamboo fiber bundles, and then dry until the moisture content of bamboo fibers is at 8%;

[0023] (3) Immerse the bamboo fiber bundles in the adhesive glue, take out the redundant adhesive glue on the bamboo fiber surface, the adhesive glue is a phenolic resin adhesive glue, and the dipping amount is 6% of the dry mass of the bamboo fiber bundles. Then the bamboo fiber bundles are dried at a temperature of 50-60°C until the moisture content is 8%.

[0024] (4) Bamboo fiber veneers and wood veneers are stacked to form embryos, the upper and lower l...

Embodiment 2

[0028] A kind of production method of bamboo plywood for building, comprises the following steps:

[0029] (1) get fresh bamboo, remove the green bamboo on the surface of the fresh bamboo, then cut the original bamboo into 3-5 pieces, remove the yellow bamboo of the fresh bamboo inner layer and the diaphragm part of the bamboo joint after dissection;

[0030] (2) bamboo chips are squeezed by a roller press to make bamboo chips become bamboo fiber bundles, and then dry until the moisture content of bamboo fibers is 10%;

[0031] (3) Immerse the bamboo fiber bundles in the adhesive glue, take out the redundant adhesive glue on the surface of the bamboo fibers, the adhesive glue is a phenolic resin adhesive glue, and the dipping amount is 5% of the dry mass of the bamboo fiber bundles. Then the bamboo fiber bundles are dried at a temperature of 50-60°C until the moisture content is 10%.

Embodiment 3

[0036] A kind of production method of bamboo plywood for building, comprises the following steps:

[0037] (1) get fresh bamboo, remove the green bamboo on the surface of the fresh bamboo, then cut the original bamboo into 3-5 pieces, remove the yellow bamboo of the fresh bamboo inner layer and the diaphragm part of the bamboo joint after dissection;

[0038] (2) bamboo chips are squeezed by a roller press to make bamboo chips become bamboo fiber bundles, and then dry until the moisture content of bamboo fibers is 10%;

[0039] (3) Immerse the bamboo fiber bundles in the adhesive glue, take out the excess adhesive glue on the surface of the bamboo fibers, the adhesive glue is a phenolic resin adhesive glue, and the dipping amount is 7% of the dry mass of the bamboo fiber bundles. Then the bamboo fiber bundles are dried at a temperature of 50-60°C until the moisture content is 10%.

Abstract

The invention discloses a production method for building bamboo plywood. The production method comprises the following steps that firstly, fresh bamboo is taken; secondly, bamboo chips are extruded through a roll presser and become bamboo fiber bundles, and then drying is conducted till the water content of bamboo fiber is below 10%; thirdly, the bamboo fiber bundles are immersed in a gluing agent, the residual gluing agent on the surface of the bamboo fiber is taken out, and then the bamboo fiber bundles are dried; fourthly, bamboo fiber veneer and wood single plates are stacked to form a blank, wood veneer is arranged on the upper face layer and the lower face layer of the plate blank, the interior of the plate blank is formed by stacking and combining of multiple layers of bamboo fiber veneer sets and wood veneer, and each layer of bamboo fiber veneer set is formed by two pieces of bamboo fiber veneer arranged in the direction perpendicular to the grain direction; fifthly, an assembled bamboo plate is pre-pressed, and then hot rolling is conducted; and sixthly, after hot rolling is finished, the finished bamboo plywood is obtained through cooling. The bamboo plywood prepared through the method is low in glue failure rate and is high in panel strength. The preparing technology is simple, implementing and grasping are easy, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of plywood, in particular to a production method of a bamboo plywood template. Background technique [0002] Bamboo plywood is a building material made of moso bamboo as the main structure and filling material, which is formed into a blank under high pressure. Bamboo has high strength, good toughness, rigidity and wear resistance, and can be used as an excellent engineering structure material. The bamboo plywood template made of bamboo has good bending strength and rigidity, good overall structure, large format, convenient loading and unloading, easy demoulding, high construction efficiency, excellent technical quality and economic benefits. However, the existing preparation technology for preparing bamboo plywood has many manual operations, complicated process, low production efficiency, and the prepared bamboo plywood has low strength. [0003] The information disclosed in this Background section is only for enhan...
