高聚物熔体平衡转矩-转速关系曲线测定方法的探讨

Investigation of the Method for Determination of Polymer Melt Steady-state Torque and Rotating Speed Relationship by Minilab Micro Compounder and Rheometer

用Minilab微型混合流变仪对高聚物熔体平衡转矩-转速关系曲线的测定方法进行探讨,实验结果表明:利用该仪器动态变速测试程序可以快速准确地得到物料的平衡转矩-转速关系曲线。

The Minilab as a means for measuring the relationship between polymer melt steady-state torque and rotating speed was investigated. The results showed that the rapid and accurate determination of the steady-state torque and rotating speed relationship could be done through a dynamic test procedure in the Minilab.
