Description
Technical field
The utility model relates to a kind of high-pressure aluminum electrolytic capacitor core that is applicable to and comprises the new equipment that soaks electrolyte.
Background technology
In the manufacturing process of aluminum electrolytic capacitor, the electrolyte impregnation is very important technology.For high-pressure aluminum electrolytic capacitor, owing to consider problem of withstand voltage, used electrolytic paper thicker (70～90 μ m), and the big (0.8～0.9g/cm of density
3), add that the viscosity of high-pressure electrolysis liquid is also bigger, soak into so contain not too easily, in order to solve the problem of this respect, the present measure of taking is: elder generation puts into the core bag and contains immersion trough; Vacuumize, get rid of the air in the core bag; Put into electrolyte (maintenance uniform temperature), under vacuum condition, carry out impregnation a period of time; Pressurization is carried out impregnation a period of time again.Because the used electrolytic paper of high pressure aluminum capacitor is thicker relatively, the density of paper is bigger, and the viscosity of electrolyte is bigger, so it is thoroughly relatively more difficult to reach impregnation.Adopting usually, " impregnation of heating " is in order to reduce electrolyte viscosity; " vacuumizing impregnation " is in order to get rid of the air in the core bag, to help electrolyte permeability; " pressurization impregnation " also is in order to promote the infiltration of electrolyte.But effect is preferably all played in all these measures to a certain extent.But still need time more than 10 hours, just might impregnation thorough.Subject matter is that it is to remain static that capacitor core wraps in the impregnation cylinder, does not get rid of at the residual bubble of the deep inside of core bag, with the electrolysis liquid phase " top dashes " that infiltration is come in, has influence on the speed of electrolyte permeability.
The high pressure aluminum capacitor impregnation time is longer, influence production efficiency on the one hand, because go between in the core bag (CP line) is that steel wire copper facing tin plated materials is made, the impregnation time is long on the other hand, iron, copper, tin material might be corroded and get off to sneak among the electrolyte, make the electrolyte property variation.So be shortened the impregnation time by the improvement to existing impregnation equipment, this is the target that mainly reaches of this patent.
