【摘要】 本文通过 Brabender 塑性记录仪,对不同交联度和不同氯含量的局部交联氯化聚乙烯(PCCPE)的流变性能进行了研究,表明交联氯化聚乙烯塑化时间和转矩随交联度增加而增加,使用交联度48%的 PCCPE加工性能好,交联度60%的 PCCPE 塑炼困难。研究结果表明:剪切应力随剪切速率、粘度的提高而增加,可见采用较大转速对 PCCPE 的加工有利。更多还原

【Abstract】 Rheological property of partially crosslinked chlorinated polyethylene(PCCPE)with different degrees of crosslinking and chlorine contents havebeen investigated by means of Brabender Plastic-Corder.In this study,it can be seen that PCCPE with crosslinking degree of 48%exhibits a good processing property,but for PCCPE with crosslinking degreeof 60% the plastification is difficult.The results show that shear stress in-creases with the increases of shear rates and visicosity.So,higher rotationalsdeed is preferable to PCCPE processing.更多还原
