摘要
使用差示扫描量热法(DSC)和热重法(TG),通过熔融焓和结晶热等热分析参数列举悬浮非改性和改性聚四氟乙烯(PTFE)原料在性能上的差异;同时采用扫描电镜(SEM)观察热处理前后PTFE原料与制品的表面形貌;研究了PTFE原料和制品在结晶度、热分解温度和加工性能等方面的差别。
This paper uses differential scanning calorimetry(DSC)and thermogravimetry(TG),the properties of granular unmodified and modified polytetrafluoroethylene(PTFE)raw materials were listed through thermal analysis parameters such as enthalpy of fusion and enthalpy of crystallization.At the same time,scanning electron microscope(SEM)was used to observe the surface morphology of PTFE raw materials and its products before and after sintering,and the differences between PTFE raw materials and its products in terms of crystallinity,thermal decomposition temperature and its processing properties were studied.
