Basic Principles and System Composition
Basic Working Principle
Basic Principle:Using butadiene as the monomer, high-cis polybutadiene rubber solution is produced through solution polymerization under the action of rare earth, nickel-based, cobalt-based or lithium-based catalysts. The final cis-butadiene rubber product is obtained through stripping, coagulation, water washing, dehydration and drying.

Operating Procedures
Purify butadiene and solvent to remove impurities and moisture, ensuring polymerization purity. Prepare the catalyst system, meter it accurately in proportion, and feed it into the polymerization system. Feed materials continuously into the polymerization reactor to complete polymerization under specified temperature and pressure. Send the rubber solution to the stripping and coagulation unit to precipitate rubber particles and wash them with water. Dehydrate and dry the wet rubber through extrusion and expansion drying to remove moisture and solvent. Briquette, weigh and package the dried rubber to obtain finished cis-butadiene rubber.
