本文研究了SBR/LDPE(丁苯橡胶/低密度聚乙烯)和HDPE/LDPE(高密度聚乙烯/低密度聚乙烯)聚合物共混体系电树枝抑制机理.试验结果指出,聚合物形态变化的物理共混(物理方法)提高聚合物共混体系电树枝起始电压(改善LDPE耐树枝特性)是基于共混体系耐麦克斯威尔应力特性的提高导致树枝诱导期的增加和延缓或终止电树枝的发展.
In this paper, the electrical inhibition mechanism of SBR / LDPE (blends of styrene butadiene rubber / low density polyethylene) and HDPE / LDPE (high density polyethylene / low density polyethylene) blends was studied.The experimental results show that the polymer morphological changes Physical Blend (Physical Method) Increasing the electrical tree initiation voltage (improving LDPE tree branch resistance) of a polymer blend system is based on the increased Maxwell-Weil stress characteristics of the blend system resulting in an increase in dendrite induction and delaying or termination of the electrical charge Development of branches.
