| 摘 要： | 对3种PE100管材专用料JHMGC100S、YGH041及P600进行了基本结构性能及毛细管流变行为、动态流变行为的研究。结果表明:190℃时,JHMGC100S的表观黏度与表观压力要高于P600和YGH041;当温度升高到230℃,3种专用料的不稳定流动现象明显改善,毛细管流变行为几乎无差别。动态流变研究表明:在低频下,JHMGC100S的复数黏度要高于其他两种专用料;在高频下,JHMGC100S的复数黏度介于其他两种专用料之间。在低频下,JHMGC100S的储能模量高于YGH041和P600;在高频下,JHMGC100S与YGH041的储能模量接近均,高于P600的储能模量。
