Embodiment 1

[0025] A kind of manufacture method of bamboo plywood, comprises the steps:

[0026] (1) The raw material selects the adult bamboo with no spot erosion and no wormhole more than 5 years of diameter more than 15cm as raw material;

[0027] (2) Cut the above-mentioned raw materials according to the length of 1.92-2.57m. After the raw material pieces are grown into strips through the corresponding punching equipment, use a planer to remove more than 95% of yellow and 100% of blue, until the length is 1.92-2.57m m, bamboo strips with a thickness of 3-10mm;

[0028] (3) adopt the steam of pressure 3.2~3.8MPa to the bamboo stick of step (2) gained, carbonize 2.2~3.5h, so that the sugar content of bamboo stick is reduced to below 5%, and bamboo fiber is reduced to below 90%, containing When the water content reaches 35%, carbonized bamboo strips are obtained;

[0029] (4) adopt rolling equipment to carry out rolling to the fiber state to the carbonized bamboo strip of step (3) gain...

Abstract

The invention discloses a method for manufacturing bamboo plywood. The method comprises the steps as follows: (1) mature bamboo which is straight and round in shape, has no pot section, no rot and no worm holes, and has the diameter of 15 cm or larger is selected as a raw material; (2) the raw material is cut off according to specific length and sliced into long strips, yellow and green are removed, and bamboo strips are produced; (3) the bamboo strips obtained in the step (2) are carbonized, and carbonized bamboo strips are obtained; (4) the carbonized bamboo strips are rolled and crushed by rolling equipment; (5) the material obtained in the step (4) is put into a phenolic adhesive for impregnation under pressure; (6) the material obtained in the step (5) is pressed into a blank by a hot press with steam as a heat source; (7) the bamboo plywood is manufactured from the blank obtained in the step (6).

Description

technical field [0001] The invention belongs to the technical field of bamboo product processing, and in particular relates to a method for making bamboo plywood. Background technique [0002] Bamboo plywood is a building material that uses bamboo as the main structure and filling material, and is formed into a blank under high pressure. Bamboo plywood is widely used, suitable for horizontal formwork, shear wall, vertical wall panel, bridge, viaduct, dam, tunnel subway and beam pile formwork in house construction, and also widely used in various containers, packing boxes, automobiles and Train floors, household floors, interior ceilings, door panels, furniture, etc. The density of the bamboo plywood produced by the existing bamboo plywood production method is not uniform enough, the process is loaded down with trivial details, and it is easy to cause unnecessary damage to the equipment. Contents of the invention [0003] The purpose of the invention is to overcome the de...
