摘要
分析了CaSt、ZnSt及协同使用对低压PE在热稳定流动时熔体性能的影响,探讨了CaSt、ZnSt协同使用时的质量比。结果表明:CaSt、ZnSt在低压PE中除了起中和作用外,其主要的作用为内外润滑作用。
The influence of CaSt, ZnSt synergistic effect on the thermal stable flow of low pressure polyethylene was analyzed. The mass ratio of CaSt to ZnSt was discussed. The results show that in addition to neutralization CaSt, ZnSt acts, its main role is internal and external lubrication.
