Embodiment Construction

[0022] The present invention will be described in detail below in combination with specific embodiments.

[0023] Choose 4-6-year-old moso bamboo, the diameter of moso bamboo is 8-15 inches, that is, the circumference is 266.6mm-500mm, according to the size required by the bamboo board, the cutting and truncating growth length are respectively: 1050mm, 1300mm, 2000mm, 2350mm, 2630mm, and then sliced ​​and rough planed to make rough planed strips. The width of the rough planed strips is: 20mm or 24mm, and the thickness is: 6.5mm, 7mm, 8mm or 9mm. The width of planed strips is: 14.3mm, 16.7mm, 17.5mm, 18.1mm or 20.8mm, the thickness is: 4mm, 5mm, 6mm or 6.5mm, the tolerance is controlled within ±0.05, and it is sorted according to different quality requirements Out of fabric, middle material, base material.

[0024] According to the requirements of the board, select the above rough planed strips, and carry out bleaching treatment under the following process conditions: temperat...

Abstract

The invention relates to a method for producing anti-crack bamboo sheet. It is characterized in following steps that: poaching the bamboo plane bar at the temperature as 50-95Deg. C and the density of hydrogen dioxide solution as 1.5-6.5%; drying the poached plane bar at the temperature as 45-65Deg. C and air relative humidity as 25-65%, to the water content as 5-9%; making the dried plane bar into fine plane bar to be coated with pastern; plane or side assembling the plane bars, to be compressed and shaped at the temperature as 88+-2Deg. C; the pressure of main compress unit is 0.2-0.6MPa, and the pressure of side compress unit is 5-7MPa; maintaining it for 3-7 days at the temperature as 20-30Deg. C and the air relative humidity as 20-50%. The invention has better anti-crack effect, which can be used in bamboo floor, etc.

Description

technical field [0001] The invention relates to the technical field of production technology of bamboo boards, in particular to a production technology of anti-cracking bamboo boards. Background technique [0002] With the continuous destruction of the ecological environment, people all over the world have regarded environmental protection as an important issue, and many countries restrict the cutting of limited forest resources. Moso bamboo has become the best substitute for trees due to its remarkable advantages. Moso bamboo is the fastest growing plant in the world, and it usually takes 4-6 years to mature, while traditional hardwoods can be used for more than 10-20 years, and moso bamboo is hard , high elasticity and toughness, the tensile strength along the grain is 170MPa, which is 2.5 times that of fir, and the compressive strength along the grain is 80MPa, which is 1.5 times that of fir. It is a natural and environmentally friendly economical...
