摘要
研究了不同种类多元醇对电石法PVC钙锌热稳定体系的影响。结果表明:多元醇的加入可以明显地延长PVC的热稳定时间,降低PVC的平衡扭矩,缩短PVC的塑化时间。
Influences of different kinds of polyatomic alcohols on Ca - Zn thermal stabilizing system of calcium carbide process PVC were studied. The results showed that the addition of polyatomic alcohols could obviously prolong the heat stability time, reduce the balancing torque and shorten the plasticization time of PVC.
