【摘要】 通过采用剖分料筒直接观察的方法,使用示踪剂表征聚合物的流动情况。采用改进后的毛细管动态流变可视化装置,通过对低密度聚乙烯(LDPE)进行大量而系统的动态和稳态挤出实验,系统地探讨了振动力场对LDPE熔体流动行为的影响。更多还原

【Abstract】 The visualization experiment method was direct observation with split barrel and tracer.The tracer was used to represent the flow state of polymer melt.LDPE was used in the experiments;numerous of experiments for steady and dynamic extrusion were systematically carried out in novel dynamic capillary rheology visualization device.The influence of vibration field on polymer melt flow state were discussed systematically.更多还原
