用热分析法探讨劣质聚氯乙烯管的鉴别方法

A Study on the Inferior PVC Tube by Thermal Analysis

用热重(TG)和微分热重(DTG)法对优质和劣质PVC管进行温度扫描,并用扫描电镜(SEM)观察其微观形貌,从而鉴别出劣质PVC管和优质管的差异.

TG-DTG and SEM techniquies were used to study the quality of PVC tubes to obtain data of thermal analysis and SEM image. The technigues can distinguish superior PVC tubes from inferior ones.
