氯化聚氯乙烯套管稳定体系的研究

Study on stability system for chlorinated polyvinyl chloride casings

研究了不同稳定体系对CPVC套管性能的影响。结果表明:复合钙锌稳定剂的稳定效果欠佳,复合铅盐类稳定剂宜与辅助稳定剂共用,有机锡稳定剂的稳定效果最好,但价格最贵。

The effects of different stabilizer systcms on the properties of CPVC casings were studied. The results showed that the stability effect of complex Ca/Zn stabilizer was not good, the complex lead salt stabilizer should be uscd together with auxiliary stabilizer, and the stability cffcct of organotin stabilizer was the best but its price was the highest.
