A process for manufacturing anti-crack bamboo plate

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...

AI Technical Summary

Problems solved by technology

The usual bamboo board production process is generally processed from moso bamboo into bamboo chips, which are bonded and pressed with an adhesive after insect-proof and anti-corrosion treatment. Although the made boards have good wear resistance, bending strength and hardness, but due Due to the special fiber structure of bamboo, it is easy to crack due to changes in ambient temperature and humidity during use, especially for products sold to European and American markets due to cracking.
