摘要
电导法测定聚氯乙烯的脱氯化氮速率,具有测试精度高、再现性好、检测公差低(10^(-6))、试样用量少等特点,并可连续测定聚氯乙烯的脱氯化氢速率,是研究聚氯乙烯早期热降解行为的有效方法。本文对该方法的实验原理、误差来源以及在研究聚氯乙烯降解过程中的应用进行了详细论述。
Conductometry to measure the rate of dehydrochlorination of PVC is advantageous to the research of the early stage of the thermal degradation of PVC, and is of high accuracy, good reproducibility, feasibility, low detection limit (10^(-3)), and a litter of samples. The principle and error source of this method in application to the degradation process of PVC are dealt with in detail.
