1.Vacuum drying: In the leather manufacturing process, the vacuum pump uses negative pressure drying to protect the leather surface from high temperature damage by removing gas and water molecules. This not only improves production efficiency, but also ensures product quality.

2.Vacuum adsorption: In the leather processing process, the vacuum pump closely fits the leather with the mold through negative pressure adsorption to achieve better molding effect. This method can improve the molding effect and reduce the scrap rate.

3.Vacuum drying oven: In the manufacture of special leather products, the vacuum pump can establish a stable vacuum environment, so that the leather products are not affected by external oxygen and impurities during the drying process, so as to ensure the quality and performance of the product.

4.Waste gas treatment: The exhaust gas produced by the leather industry contains a large number of organic matter and odorous substances, and the vacuum pump collects the waste gas through negative pressure adsorption, and further treats and filters it, so as to reduce the impact of waste gas emissions on the environment and achieve the purpose of environmental protection.

5.Improve the utilization rate of chemical materials: In the process of wet processing, the negative pressure effect of the vacuum mechanism can be used to improve the physical-chemical environment and the kinetic conditions of reaction equilibrium in the process of tanning process, so that the fiber structure of the raw leather plate can be loosened and expanded from the inside to the outside and the skin plate tissue can be degassed to form a void, which is conducive to the rapid and uniform penetration of chemical materials into the skin fiber structure and improves the utilization rate of chemical materials.

6.Reduce waste liquid discharge: The application of vacuum pump can make the water in the tanning operation fluid volatilize, and the solution is continuously concentrated to maintain a certain permeation gradient, forcing the active ingredients in the operating fluid to penetrate more into the skin and be absorbed, thereby reducing the content of harmful substances in the waste liquid. The concentrated operating fluid can also be reused, reducing the total effluent discharge.

7.Shorten the working time and improve the quality of the finished leather: the use of vacuum drum greatly shortens the working time, improves the efficiency and quality of the finished leather, reduces the discharge of harmful waste liquid, and has important social and economic benefits.

To sum up, the application of vacuum pump in the leather tanning industry improves production efficiency and product quality, and is one of the indispensable technologies in the leather industry.
