硅灰石填充尼龙-6复合体系的非等温结晶行为及动力学研究

摘要

The non-isothermal crystallization behaviour of nylon-6 filled with wollastonite composite was studied by means of DSC. The crystallization kinetics was investigated by Avrami and Mo method. The results show that with the increasing of cooling rate, the crystallization peak shifts to lower temperature with variable width, and the crystallization rate increaes. By contrast, the non-isothermal process of nylon-6 filled with wollastonite composite was described more appropriately by Mo method.%用差示扫描量热法(DSC)考察了硅灰石填充尼龙-6复合体系的非等温结晶行为,并用Avrami以及Mo法研究了其非等温结晶动力学.结果表明,随着降温速率的增加,复合体系的结晶峰变宽并向低温方向移动,结晶速率增加.通过对比,Mo法能很好地描述硅灰石填充尼龙-6复合体系的非等温过程.
