【摘要】 将辉绿岩纤维与PVC用XSS 30 0流变仪混炼,测得了转矩与时间的关系曲线。研究了PVC的塑化时间tm、扭时矩TTQ及平衡转矩TQS 与辉绿岩用量的关系和PVC的塑化时间与偶联剂用量的关系,以及预设加工温度及转速对混炼工艺的影响。研究结果表明,辉绿岩含量不超过30 % ,偶联剂用量不超过2 %时,加工能够顺利进行。最佳加工温度为178℃,最佳转速为4 0～5 0r/min。更多还原

【Abstract】 Diabase fibers and PVC were melt mixed in an XSS-300 Torque Rheogoniometer.The PVC melting time(t m), integral area of torque time(TTQ) and equilibrium torque(TQ S) were studied. The author also studied the effect of preinstalled processing temperature and rotational speed on the processing technology. It shows that the process of diabase/PVC composites can be trouble-free operated when the diabase content is less than 30% and the coupling agent content is less than 2%. The optimal processing temperature is 178 ℃ and optimal rotational speed is 40～50 r/min.更多还原
