摘要
在热塑性塑料熔体流动速率的测定过程中经常遇到测定误差过大的现象,文章从预热时间、过负荷外力、活塞杆测试位置等几个方面就减小误差进行分析论述,供从业者参考。
Superior test deviation phenomenon was often occurred in the test course of melt flow speed of the thermoplastic plastics.Factors such as preheat time,overload external force,test position of the piston rod were analyzed and described to reduce the deviation,which provided references to the practitioner.
