摘要
根据Avrami方程和瞬时传热模拟对于205℃、210℃和220℃PET等温结晶的DSC曲线进行了模拟计算,计算值与实验值吻合,且求得了主、次结晶过程的动力学参数和热焓值。
According to Avrami equation and transient heat transfer model,DSC profiles of PET isothermal crystallization,at 250℃ ,210℃ and 220℃,respectively, were simulated. The profiles of simulation are essntialy agreed with those of experiment. The kinetic parameters and the values of enthalpies, for primary and secondary stage of crystallization, were calculated.
