CJF series lift-type high-pressure stirring vessels are widely used in reaction vessels for gas-liquid, liquid-liquid, liquid-solid or gas-liquid-solid three-phase chemical materials. CJF series adopts static sealing structure, and the stirrer and motor drive are connected by magnetic coupling, which completely solves the leakage problem caused by dynamic sealing and stirring. Therefore, CJF series is very suitable for stirring reaction of various flammable, explosive, toxic, highly permeable and precious chemical media. It is an ideal non-leakage reactor for vulcanization, fluorination and oxidation in petroleum, chemical, organic synthesis, polymer polymerization, food processing and other fields.
