The products such as charger, electric ballast, the resistant to elevated temperatures requirement of aluminium electrolutic capacitor also more and more higher is mutually tackled, especially to high jewelling
Electrolytic capacitor.Due to larger by the ripple current of capacitor, capacitor can generate heat in itself and long time continuous working, makes
It is more and more stricter to obtain requirement of the electronic product to capacitor, is mainly reflected in：Heat-resisting quantity in small volume, high pressure working environment
Energy, long lifespan.
Real negative electrode of the working electrolyte for aluminium electrolytic capacitor as aluminium electrolutic capacitor, its characteristic is to aluminium electrolutic capacitor
Play a decisive role.In the prior art, Working electrolyte is typically formulated in proportion by solvent, solute and various additives, molten
Agent includes pure water, ethylene glycol, gamma-butyrolacton, diethylene glycol (DEG) etc., and solute is organic carboxyl acid and its salt, and additive includes flash over voltage
Enhancer, drain current suppressing agent, the hydrogen agent that disappears, waterproof mixture, fire retardant etc..But needed under given conditions for capacitor
It is operated, it is necessary to which it is reasonable that the collocation to the dicyandiamide solution in Working electrolyte, solute composition and various additives is carried out
Selection, otherwise will cause the poor-performing of some aspects of capacitor, and then be difficult to meet production demand.
Such as：Requirement of the high-pressure aluminum electrolytic capacitor to Working electrolyte be：There is higher flash over voltage, ensure
Under condition of high voltage can normal work, avoid because Working electrolyte flash over voltage is too low there is scintillation cause capacitor drum bottom lose
Effect even breakdown and explosion.And in high-pressure aluminum electrolytic capacitor Working electrolyte, it usually needs addition flash over voltage to carry
High agent, and conventional flash over voltage enhancer has polyethylene glycol PEG, polyvinyl alcohol PVC, polymerized fatty acid, nanosized SiO_2 etc., it is right
In addition of any flash over voltage enhancer as formula, and need what is reasonably selected, otherwise will cause to produce
The quality of product is still not being met.
In addition, the medium of aluminium electrolutic capacitor is alundum (Al2O3) oxide-film, and Working electrolyte is to cover completely
Lid, infiltration alundum (Al2O3) oxide-film, therefore, the quality for medium is also the key of aluminium electrolutic capacitor quality quality.And
Working electrolyte, wherein containing moisture, easily with alundum (Al2O3) oxide-film hydration reaction occurs for moisture, causes alminium electrolytic condenser
The performance of device deteriorates in advance so that the service life of product shortens, and in the process, when solved frequently with waterproof mixture is added
Certainly；Meanwhile aluminium electrolutic capacitor is in the course of the work, meeting auto-mending anode alundum (Al2O3) oxide-film, the oxidation of repairing three two
The process of alumite can produce hydrogen, and caused gas is more, and the pressure of capacitor internal is higher, finally rouses capacitor
Bottom is until explosion-proof valve is opened and failed, and in the process, generally use, which adds, disappears hydrogen agent to solve.
Based on this, in the process for preparation of working electrolyte for aluminium electrolytic capacitor, for dicyandiamide solution, solute composition and
The Rational choice of other additives becomes key, and chooses result for above-mentioned substance, will also directly affect aluminium electroloysis
The quality of electrolyte capacitor working electrolyte.
Also just so, this researcher is studied by the characteristic of the capacitor used under the hot environment to 130 DEG C,
Research is made by the material composition to working electrolyte for aluminium electrolytic capacitor and proportioning so that the Working electrolyte of acquisition is used for
