PP粒度分布的工艺控制

摘要

聚合工艺控制参数如催化剂颗粒的粒径、聚合反应温度、聚合物浆液的平均停留时间等的波动，会导致PP粒度分布变宽而引起下游工艺系统的堵塞。针对影响 PP粒度分布的诸因素，对工艺控制条件进行了优化。%The influence factors of PP particle size distribution,such as catalyst particle size,polymerization temperature and mean residence time of polymer slurry,were analyzed.The process control conditions were optimized for PP particle size distribution equality.
