A kind of anti-mildew and anti-corrosion technology of bamboo board

Abstract

The invention discloses a mildew-proof and anti-corrosion process for bamboo boards, which includes: placing bamboo boards in a vacuum chamber, and closing the door of the vacuum chamber; vacuuming the vacuum chamber to 0.01Mpa-0.02Mpa for 10min- 30min to keep the bamboo board in a vacuum environment; feed ammonia gas into the vacuum chamber and continue vacuuming to replace the air in the bamboo board, keep the pressure of the vacuum chamber atmosphere at 0.02Mpa-0.06Mpa and continue for 10min-20min; feed ammonia gas Adjust the atmospheric pressure of the vacuum chamber to 0.07Mpa-0.08Mpa, pass the aqueous solution of anti-mold preservative from the bottom of the vacuum chamber until the bamboo board is submerged, and maintain the dissolution or reaction time of ammonia in the aqueous solution of anti-mold preservative for 10min- 40min; open the door of the vacuum chamber to release the vacuum in the vacuum chamber, and discharge the anti-mildew and preservative aqueous solution after the vacuum is released for at least 5 minutes; take out the soaked bamboo board and place it in a drying room for drying; dry it The bamboo boards are taken out and put into the carbonization chamber for carbonization treatment. The present invention carries out all-round treatment on the inside and outside of the bamboo board, so that both the inside and the outside of the bamboo board have anti-mildew and anti-corrosion functions.

Description

technical field [0001] The invention belongs to the field of wood processing, and in particular relates to a mildew-proof and anti-corrosion process for bamboo boards. Background technique [0002] As a common wood, bamboo board is widely used in daily life, such as bamboo mat, bamboo floor, bamboo chopsticks, bamboo sticks and so on. However, bamboo boards are often prone to insects, mildew, and discoloration due to improper handling during the application process, especially in wet conditions, which are more likely to occur. [0003] Now for the anti-mold and anti-corrosion treatment methods of bamboo boards, they often only treat the surface of bamboo boards and the places not deep from the surface. That is to say, only the surface layer of the bamboo board is treated with anti-mildew and anti-corrosion treatment. When this kind of bamboo board is used, problems such as moth and mildew may occur inside the bamboo board. And once this bamboo plate will be cut and used, ...

AI Technical Summary

Problems solved by technology

When this kind of bamboo board is used, problems such as moth and mildew may occur inside the bamboo board

Moreover, once this kind of bamboo board is to be cut and used, it is very troublesome to re-do anti-mildew and anti-corrosion treatment at the incision.
