Description
Technical field
The utility model relates to aluminium electrolutic capacitor field, specifically a kind of chemical conversion folder for solid capacitor preparation
Tool.
Background technique
Capacitor is a kind of device for accommodating charge, is one of the electronic component largely used in electronic equipment, answers extensively
It for the separated by direct communication in circuit, couples, bypasses, filtering, resonant tank, energy conversion, control etc..With electronic information
Technology is maked rapid progress, and the update speed of digital electronic goods is getting faster, with flat panel TV, laptop, number
Consumer electronics product volume of production and marketing sustainable growth based on the products such as camera has driven capacitor industry to increase.
Takeup type solid-state aluminum electrolytic capacitor is exactly a kind of common capacitor, it and traditional liquid aluminum electrolytic capacitor
It is maximum the difference is that use different catholytes.Liquid aluminium capacitance cathode electrolyte is electrolyte, and solid capacitor
Catholyte be then solid state conductive polymer material.The conductive capability of solid state conductive polymer material is higher compared to electrolyte
(the high 2-3 order of magnitude of conductivity), thermal stability is good, has fundamentally prevented the hidden danger of leakage, quick-fried slurry, has long-life, resistance to
High temperature, using safe, low ESR, high ripple current the advantages of.
But one of the defect of solid state conductive polymer material is cannot to repair oxidation film, and solid capacitor core packet is being made
The aluminium foil notch No oxided film covering generated during work, and collision, vibration and the scratch in production process can also make aluminium foil table
The oxidation film in face generates defect.It is soaked again so capacitor core packet must be first melted into repairing oxidation film when making solid capacitor
Enter solid state conductive polymer material, the production procedure of solid-state aluminum electrolytic capacitor is as follows: (1) cutting: by anode foils, Cathode Foil,
Electrolytic paper cuts into specified width, which width；(2) winding core packet: by the nail riveting of positive guide pin on anode aluminium foil, negative guide pin nail riveting is in cathode aluminium
On foil, electrolytic paper is clipped between anode foils and Cathode Foil is wound into core packet together；(3) it prepares sub-prime: core packet is welded on iron bar
On through chemical conversion, drying, impregnation pretreating reagent, impregnation monomer, impregnation oxidant, sub-prime is made after high temperature polymerization；(4) group is vertical: logical
Automatic assembling machine is crossed, the sub-prime prepared is sealed with rubber stopper, aluminum hull；(5) product that stand of group through aging, stamp, add
Work, packaging can shipment.
Chemical conversion is wherein important step, is that the capacitor core packet after the completion of winding is immersed to logical direct current in electrolyte to repair
The process of multiple oxidation film, canister is the cathode of electrolytic cell in existing chemical synthesizing method, and anode foils are the anode of electrolytic cell.In
Under normal circumstances, due to there is the presence of barrier paper, impedance is big between Cathode Foil and anode foils.So passing through Cathode Foil when being powered
Electric current very little, potential difference between Cathode Foil and forming liquid is less than Cathode Foil pressure resistance, and Cathode Foil surface oxidation film thickness will not
Increase.With the increase of conduction time, the fault location of anode foils covers dielectric oxide film again, and electric current is gradually reduced, to electric current
Chemical conversion is completed when stablizing.But aluminium foil has certain probability to generate small burr or foil ash cutting with nail joint process, these
Burr or foil ash, which may pierce through barrier paper, leads to anode foils and Cathode Foil short circuit, and anode foils and Cathode Foil become electrolysis jointly at this time
The anode in pond is melted into jointly.Because the pressure resistance of Cathode Foil is smaller (be not more than 3V), by electric current it is very big, lead to the defeated of power supply
Voltage declines out, even if these small burrs or foil ash are melted or burnt by the heat that electric current generates, but Cathode Foil is because of chemical conversion
The oxidation film of generation can permanently destroy its structure, reduce specific volume, condenser capacity is caused to decline, and DF and ESR increase, this is just
Inconvenience is brought for the use of people.
