Influence analysis of propylene purity on polypropylene process and control measures
The quality of propylene directly affected the quality and performance of polypropylene production.The unqualified propylene would lead to bubbles,poor thermal stability,insufficient tensile strength and other problems in polypropylene products,which seriously affected the application effect and production efficiency.In order to solve the influence of the quality of propylene on the production of polypropylene,this paper focused on the influence of impurities including H2O,S and As in propylene raw materials on the polymerization reaction,put forward the critical operations of strictly controlling the propylenepurity and regulating the amount of catalyst,so as to ensure the quality and economic benefits of polypropylene products steadily improved and meanwhile,providedthe better protection and support for the development of the polypropylene industry.
