导电碳黑填充EVA半导电电极对聚乙烯中空间电荷注入的影响
Space Charge Injection in LDPE by Semi-conductive Electrode with Different Carbon Black Filling Rates
摘要
Abstract
Electrode materials may play an important role in space charge accumulations. Seml-eonductive electrodes, carbon black （CB） with ethylene vinyl acetate copolymer （EVA） at three different filling rates, 27%, 32%, and 34%, respectively, were adopted to study their space charge injection by the pressure wave ropagation （PWP） method. Results show that, higher CB filling rate induces lower space charge injection than the electrode with lower CB filling rate. It is in agreement with the theoretical analysis. Both the large CB particle size and low CB filling rate can obviously lead to high local electric field near the surface of the CB particles and a large region of high field; which may cause more charge injection.关键词
