melt shear viscosity

By contrast, the viscosity of a melt of a plastic at a constant temperature changes markedly as the shear rate changes.

与之对比的是，塑料熔体在一定温度下粘度随着剪切速率的变化而变化。

Influences of composition of the blends, shear stress, shearing rate and temperature on the rheological behavior and viscosity of the melt were discussed.

讨论了共混物的组成、剪切应力和剪切速率以及温度对熔体流变行为、熔体粘度的影响。

Moreover, the low molecular weight and higher temperature are favorable to reduce the melt viscosity, to increase the critical shear rate and to improve the apparent quality of extrudates.

较低的分子量和较高的温度有利于提高临界剪切速率，改善挤出物外观质量和降低熔体粘度。
