快速成型尼龙66的非等温结晶动力学分析
Kinetics of Non-isothermal Crystallization for Rapid Prototyping Nylon 66
摘要
Abstract
The non-isothermal crystallization behavior of rapid prototyping nylon 66(RP PA66) was stud-ied by differential scanning calorimeter ( DSC ) .The non-isothermal crystallization kinetics of RP PA 66 was analyzed by Jeziomy equation , Ozawa equation and Mo Zhishen equation respectively .Jeziomy equa-tion analysis results showed that the non-isothermal crystallization process included main crystallization and inferior crystallization .The Avrami index n and the crystallization rate constant Zc of the main crys-tallization were different from the inferior crystallization , which suggested that RP PA 66 nucleation mech-anism and crystal growth were in a different way .The Ozawa equation was not suitable for the crystalliza-tion behavior of RP PA66, and the Mo Zhishen equation could effectively describe the non-isothermal crystallization behavior of RP PA66.关键词
