On the contrary, when melttemperature is too low, the melt viscidity becomes intensive, so cavitation and acoustic streaming are in no effect.
如果施振温度过低,熔融合金粘度就会增大,致使声空化和声流效应发挥不了应有的作用。

For these low melting point polyesters with different content of modifier r, the influence of temperature on viscosity of melt must be paid attention during post processing.
对于改性剂r含量不同的低熔点聚酯,在后加工时应充分考虑到温度对熔体粘度的影响。

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.
