聚醚多元醇对电容器性能的影响

The Application of Polyether Polyol in Electrolyte

把聚醚多元醇加入电解质中,会对电解电容器的漏电流(Ic)、损耗(D)和电容量(C)产生影响。聚醚对漏电流的影响与它在电解质中的含量有关,聚醚GE对电容器的漏电流的减小作用比聚醚JE大。聚醚还可以提高电解液的闪火电压(Us),延长阳极氧化铝膜的耐压时间,延长电容器的寿命。

The addition of polyether polyol in electrolyte would affect the leakage current, capacity and dissipation of the electrolytic capacitors. The polyether＇s influence on leakage current was related to its content in the electrolyte. The polyether GE could more efficiently lower the leakage current than polyether JE did. The polyether polyol could enhance the sparking voltage （US） of electrolyte and prolong voltage duration of anode alumina and the life of capacitors.
