The product users of dry screw vacuum pump include some wood production enterprises, such as common antiseptic wood production. Many people do not understand the role of vacuum pump in wood production. Kelexi uses a simple process and diagram to tell you how the vacuum pump plays a role in the production of antiseptic wood.

The core technology of preservative wood production is to infiltrate preservative into wood through vacuum and high pressure impregnation, realize the conversion of preservative with starch, cellulose and sugar in wood, destroy the living environment of bacteria and ants causing wood decay, and improve the outdoor preservative performance of wood.

In the process, firstly, the dried wood is put into the pressure tank, and the air in the tank is removed by the vacuum pump (the cell structure of the dried wood will be relatively fixed, so as to reduce the cracking and deformation of the wood, and facilitate the immersion of preservatives. In addition, wood vacuum drying is also one of the vacuum pump applications); then the wood is injected with a specific preservative, and then the preservative is penetrated into the inner layer of the wood through pressure; during the vacuum high-pressure impregnation, high-temperature qualitative analysis is also needed to improve the anti-corrosion performance; after the completion of the vacuum high-pressure immersion, the vacuum pump is also needed to realize the vacuum recovery of the redundant preservatives to reduce the agent on the environment Finally, the wood is dried out of the tank for equipment drying and natural drying to ensure that the preservative components are fully fixed in the wood. After this step is completed, the antiseptic wood can enter the processing and finalization stage and be applied to the specific scene.
