【摘要】 采用毛细管流变仪和Ｂｒａｂｅｎｄｅｒ 流变仪测试了聚酯切片熔体的流变特性，发现熔体的粘度对温度非常敏感，熔体剪切变稀的现象很明显，讨论了粘度特性对物料加工温度等参数的影响。更多还原

【Abstract】 The rheological behaviour of molten polyester specimens was studied using a capillary rheometer and a Brabender torque rheometer. The results show that the viscosity of the melt is remarkably influenced by temperature and shear rate. The influence of the viscosity characteristics on some of the processing parameters is also discussed.更多还原
