Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticide, dye, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization and condensation, such as reactors, reaction pots, decomposition pots, polymerization pots, etc.; the materials are generally carbon-manganese steel, stainless steel, zirconium, nickel-based alloys and other composite materials.
