There is the problem of electrical conductivity is low in solution liquid, and boric acid and its salt easily occur esterification with ethylene glycol at high temperature and generated a large amount of
Condensation water, cause the moisture inside electrolyte to raise, the vapour pressure of electrolyte increase, capacitor internal pressure is raised and caused
Capacitor valve opening fails;2nd, using ethylene glycol as main solvent, using the direct-connected hydrocarbon saturation two such as azelaic acid, decanedioic acid or 12 diacid
Carboxylic acid and its salt are electrolyte solution, and although the electrolyte of this class avoid a part of esterification, but be due to this
Solubility of the linear paraffin of one class in ethylene glycol is smaller, causes the impedance of product larger, easily generates heat and makes under big ripple
Solvent volatilizees, so as to produce vicious circle, causes capacitor withered and fails, while acid amides easily occurs at high temperature for linear paraffin
Change side reaction generation water, also easily cause capacitor initial failure;3rd, using the 1 of some branched acid or its salt, such as report,
6-DDA and its salt and 2- butyl suberic acid and its salt, this kind of branched carboxylic acid and its salt compare straight chain to the solubility of solvent
Alkane increases, thus generates effect to a certain extent, but simultaneously, and this kind of acid or its salt rely primarily on import, thus into
This height and restraining factors are more.
