Based on experiment and data calculation, this viscosity model could sensitively and quantitatively reflect the impact of the processing parameters on the apparent viscosity of the melt.
依靠实验及数据计算，检验此模型能够灵敏地定量反映外部加工条件对熔体表观粘度的影响。
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。
Experiments reveal that the apparent viscosity of the melt flameretardant PP decreases with increasing additive. The breaking strength of flameretardant PP fiber decreases with increasing additive.
结果表明，随阻燃剂的增加熔体的表观粘度下降，并且阻燃纤维的断裂强度也下降。
