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%.
[0032] (4) Bamboo fiber veneers and wood veneers are stacked to form embryos, the upper and...
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%.
[0040] (4) Bamboo fiber veneers and wood veneers are stacked to form embryos, the upper and lo...
