Control Measures for Reducing the Ash Content of Batch Polypropylene
The intermittent liquid bulk polypropylene process was developed in China in the 1970s.The process has the characteristics of short process,simple equipment,small investment and quick effect.But with the polypropylene to improve the quality and quantity requirements(the process at the same time there is a product quality is not stable,single variety,the disadvantage of higher cost),special grades of polypropylene as the present market shortage of products,including low ash polypropylene is more and more people are becoming more and more become the focus of attention,testing the polymerizer operating flexibility.This paper introduces the control measures of reducing the ash content of batch polypropylene.
