聚丙烯异味原因分析及对策

Causes and Countermeasures of Peculiar Smell of Polypropylene

针对聚丙烯产品存在异味的问题,通过定性定量分析,确定引起聚丙烯异味的物质是硫醇、硫醚等硫化物。对丙烯原料溯源分析,认为聚丙烯产品异味问题与使用焦化液化气生产的炼油丙烯原料有关。通过对原料丙烯生产、丙烯精制、聚丙烯生产全流程管控,采取针对性措施,可消除聚丙烯产品异味。

In view of the problem of peculiar smell in polypropylene products, through qualitative and quantitative analysis, it is determined that the substances causing the peculiar smell of polypropylene are sulfides such as mercaptan and sulfide. According analyzing the source of propylene raw material, the polypropylene odor is related to the refining propylene raw material produced by coking liquefied gas. Control the whole process of raw propylene production, propylene refining and polypropylene production, and take targeted measures to eliminate the peculiar smell of polypropylene products.
