根据冷模优化实验结果 ,聚合首釜搅拌底桨由双螺带式改为四叶框式和催化剂B由微偏心位置改为偏心位置进料 ,在生产中应用后 ,聚合釜中单体、溶剂和催化剂的混合分散更均匀 ,最终降低了催化剂的用量 ,橡胶的内在质量也得到改善 ,在原料质量下降时 ,可稳定聚合反应。 According to the results of the cold model optimization experiment, the first propeller of the first reactor of the polymerization was changed from double helix band to four-leaf frame type and the catalyst B was changed from the micro-eccentric position to the eccentric position for feeding. After being used in the production, monomers, The solvent and catalyst are more uniformly dispersed and dispersed, ultimately reducing the amount of the catalyst and the intrinsic quality of the rubber is also improved. When the quality of the raw material is deteriorated, the polymerization can be stabilized.
