摘要
使用自制的毛细管动态流变仪挤出聚丙烯(PP)与CaCO_3混合料,研究了振动参数对CaCO_3在PP中分散效果的影响。试验发现,随着振动频率和振幅的增加,CaCO_3的平均粒径逐渐变小,因而证明了振动力场的引入有效地促进了CaCO_3的分散。
Polypropylene(PP) and CaCO3 blends were extruded in self-made dynamic capillary rheometer, and the effects of vibrating parameters on the dispersion of CaCO3 in melted PP were studied. The results indicated that average diameter of CaCO3 tended to decline with the increase of vibrating amplitude and vibrating frequency, which proved vibration field effective to accelerate the dispersion of CaCO3 in PP.
