Procedure for activating industrial electrolytes

Me in the "Eisten cases ms Irei Kosaponenteii _{8 g,} for example ms BersIwe _i, an alkali (especially ammonia) and a LQsiangs- and Veresteraagmittel, from polyhydric alcohols ₀ Glyaerin © the Iithylenglykol ₉ existing operating electrolytes have various laefeteile to preferably such as" So, there at SoB. About 400 volts underlying tensions high viscosities of the common operating electrolytes occur, a Durehimprägnieresi the Kondenaatorwickel extremely difficult feasible Sehwarakungen "and delays in Formierverlauf make long F ^ naierzeiten required" Finally join Erreieimng v "tension districts about 500 volts _p eg 550-600 volts _for rollovers and BurchsohlSge in the capacitor bank, which lead to a short circuit between the capacitor foils. To eliminate these and other disadvantageous properties of the operating electrolytes »so that they can also be used at higher operating voltages, e.g. above 550 volts _p , or at least the properties that are still sufficient for smooth foils at operating voltages of up to 550 volts with regard to the viscosity of the operating electrolyte The object of the present invention is to improve the fact that it can be used for capacitors with a roughened foil. According to the invention, it is alleviated by the fact that monomeric polymerizable substances which are free of chlorine ions are introduced into an operating electrolyte, which preferably consists of boric acid, an alkali, and solvents or esterifying agents.
