该文研究了采用封闭剂系统的聚合物助留工艺——使用直链型和支链型的聚合物作为封闭剂来研究其对桥连型聚合物助留效率的影响。研究表明,在浆料悬浮液中使用封闭剂可改善助留体系的效率,这是由界面上聚合物伸展形态的加强所造成的。这种结果表明,在留着过程中聚合物形态是很重要的。
This paper studies the polymer retention process with a blocking agent system - using linear and branched polymers as blocking agents to study their effect on retention efficiency of bridged polymers. Studies have shown that the use of a sealant in a slurry suspension can improve the retention efficiency of the retention system due to the enhanced polymer extension at the interface. This result shows that polymer morphology is important during retention.
