Polytetrafluoroethylene is a high molecular polymer polymerized with tetrafluoroethylene as a monomer. The chemical formula is (C2F4)n. It has excellent heat and cold resistance and can be used for a long time at -180-260°C. This material has the characteristics of resisting acid, alkali and various organic solvents and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance and extremely low friction coefficient. Therefore, it can not only be used for lubrication but also be an ideal coating for easy cleaning of the inner layer of water pipes. By providing the polytetrafluoroethylene coating 93 on the inner wall of the tank body 3, the possibility of raw materials adhering to the inner wall of the tank body 3 can be reduced.

[0047] As shown in Figures 1 to 6 , the bottom of the tank body 3 is installed with a manual valve 94. After the raw materials in the tank body 3 are stirred uniformly, the workers make the bottom of the tank body 3 communicate with the outside through the manual valve 94, thereby facilitating the discharge of the raw materials in the tank body 3.
