摘要
通过对照找出丙纶老化现象在差热分析图谱上的反映,特征是两个吸热峰的位置前移;峰高和面积减少;后峰呈现锯齿状;而且放热峰消失。用此方法还研究了温度、紫外光和酸碱介质等外界条件对丙纶老化的影响。
The appearence of aged polypropyrene silk appeared in the figure of DTA were found by check test, with the position ofthe two endothermic peaks moving forward, the peak height and area reduced, the saw-tooth appearence of the back peak anddisappearence of the exothermic peak. The influence of temperature, ultra-violet light, acid and alkali medium and others onageing of the polypropyrene silk was also researched in this paper.
