Background

Polyethylene and polypropylene are polymers obtained by addition polymerization. The method is widely applied to various industries such as clothes, automobiles, medical instruments, conveying pipelines, chemical pipelines and the like. The polymerization reaction is a process of converting a low molecular weight monomer into a high molecular weight polymer, and substances such as a monomer, a solvent, an initiator, a catalyst and the like exist in a reaction container in the polymerization process, so that the reaction process is complex, and the control of the working condition in the reactor during the polymerization reaction has direct influence on the reaction result.

In engineering, the polymerization reactor has been successfully applied to the polyolefin field such as polypropylene and polyethylene, and is a core device in the polyolefin project. During polymerization, a monomolecular medium in the container is subjected to polyaddition reaction under the conditions of a catalyst, pressure, temperature and the like, and in the process, bulges and uneven parts in the internal structure of the reaction kettle can generate polymerization reaction locally to cause material accumulation and influence the normal use of equipment, so that the internal structure of the reaction kettle needs to be optimized to prevent local polymerization reaction.
