Description

Technical Field

[0001] The utility model relates to the technical field of terminators, in particular to a polymerization reaction terminator feeding device. Background Art

[0002] Terminator is also known as polymerization stabilizer, chain terminator, and polymerization inhibitor. It is an agent used in the polymer chemical chain polymerization process, and is a substance that can terminate the polymerization reaction in the chain polymerization reaction. These substances can react with the initiating free radicals and the growing free radicals, making them inactive, thereby terminating the growth of the chain and stopping the polymerization reaction from continuing. Its function is to be a terminator of free radicals. By terminating the polymerization reaction in time, high-quality polymer products with uniform molecular weight and stable molecular structure can be obtained. In the production, storage, and transportation of some polymerization monomers, in order to prevent the occurrence of automatic polymerization reactions of monomers, terminators need to be added, such as monomers such as styrene and methacrylic acid, which act as stabilizers and polymerization inhibitors.

[0003] Polymerization terminators are chemical substances used to stop or slow down the polymerization process. However, currently, when adding terminators to the reactor, they are generally poured directly into the reactor by staff manually. Although this method is simple, the operator needs to judge the amount of terminator added based on experience and actual conditions. The dosage control is more difficult and can easily lead to overdosage or underdosage. Utility Model Content
