Description
Technical field
The present invention relates to molecular sieve acid control device, before particularly relating to a kind of high energy mixed capacitor sealing, during ageing, prevent work
Make the molecular sieve acid control device of electrolyte splash or overflow or evaporation, belong to electrolysis condenser manufacturing technology field.
Background technology
Tantalum capacitor normally can work under conditions of variations in temperature is violent, and its volume is little, capacity big, than
Big more than 2 times of the capacitance of other capacitors of same volume, plays important work to miniaturization of electronic products development and performance boost
With.Tantalum electrochemical capacitor is mainly used in the circuit that alminium electrolytic condenser performance parameter is difficult to meet requirement, as required electric capacity volume
Little, temperature range width, frequency characteristic and impedance operator require aviation that height, product stability and reliability requirement are high, civilian whole
Dynamo-electric road etc..High energy mixing tantalum ultracapacitor has the features such as volume is little, running voltage is high, capacitance is big, as novel
Free of contamination energy-storage travelling wave tube, be widely used in the military of the fields such as impulse circuit, wave filter, communication apparatus, medical instrument and
In civil electrical and electronic equipment, particularly can provide power for vehicle electronics, the development of electric automobile can be promoted,
The pollution to environment of the tail gas of minimizing motor vehicle emission, therefore has market prospect widely.The capacitance of high energy mixing tantalum capacitor
Scope 3300~200000 μ F, in current liquid tantalum capacitor, it is achieved that the capacitance of high unit volume.
In electrolysis condenser technology of preparing, ageing is requisite screening technology.Ageing refers to the tantalum electricity assembled
Electrolysis condenser is placed under certain ambient temperature, applies a certain voltage more than rated capacitor value, the electricity to product continuously
Parameter carries out repairing and eliminating the technological measure of the product that can not repair.By this PROCESS FOR TREATMENT, not only can repair because of
Former procedures (such as assembling etc.) and the oxide-film that damages, make the performance of capacitor tend towards stability, and can also reject those and have
The product that open defect, leakage current are excessive, compressive resistance is low, improves the reliability of capacitor.Technique for ageing is divided into sealing ageing
With opening ageing two ways.From the point of view of high energy mixing tantalum capacitor, if using sealing ageing mode, high energy mixing tantalum electricity
The anodic wick of container (< 100 DEG C) under the conditions of higher temperatures can carry out selfreparing to the defect on anode oxide film, is repairing
During Working electrolyte generation chemical reaction discharge gas, and the vaporization of Working electrolyte so that capacitor internal gas pressure
Rising causes shell dilatancy, even makes outer casing rupture cause product rejection.So current high energy mixing tantalum capacitor
Ageing uses opening ageing mode;Experiment proves that opening ageing can significantly reduce product leakage current value, avoid puncturing and carrying
High qualification rate.But opening ageing there is problems in that (1) during opening ageing, tantalum anode fuse is under the function of current
Heating and high temperature aging condition itself Working electrolyte is seethed with excitement, so that from the electrolyte inlet of capacitor surface
Overflow and the shell of polluted product;(2) due to heat effect, the volatilization of a small amount of electrolyte becomes gas, the electrolyte meeting evaporated
Accelerate ageing stove, the corrosion of aging clamp;(3) close to anode exit of the electrolyte overflowed and the electrolyte evaporated
Sealed insulator has strong corrosiveness thus destroys the sealing of insulator, can directly contribute electricity during product later stage work
Solve liquid leakage phenomenon, thus cause capacitor failure.At present, the main technique form for opening ageing is to stick at acid-filling mouth
With hygroscopic paper tape, paper tape still cannot be avoided the outflow of sulphuric acid, more can not stop the volatilization of sulphuric acid.(4) when stopping
Only after ageing, after stopping ageing, electrolyte will run off greatly, not only cause waste, more seriously product
The meeting out of control of Inner electrolysis liquid measure causes particular product performance parameters big ups and downs.
