氧化物的性能对PVC热稳定性的影响

Effect of Oxide PVC Thermal Stability Properties

通过对氧化物的粒度分布和比表面积的测定研究了氧化物表面性能对PVC热稳定性的影响。结果发现,氧化物的粒径大小对PVC动态热稳定性的影响具有决定性的影响,而氧化物的比表面积决定PVC静态热稳定性。

The thermal stability effects of different types of oxide mixture on PVC were studied. The results show that the oxide with the smaller particle diameter demonstrates better dynamic stabilizing effect. However, the static thermal stabilizing effect of PVC containing the oxides is determined by the specific surface area of the oxide, in other words, the oxide with the bigger speific surface area shows better static stabilizing effect than that of the oxide with smaller ones.
