Description
Technical field
The present invention relates to aluminium electrolutic capacitor medium-high pressure chemical foil production technical field, particularly aluminium electrolutic capacitor improves method and the device of Waste Acid From Hua Cheng Foil visual appearance in using.
Background technology
The primary base material of aluminium electrolutic capacitor Waste Acid From Hua Cheng Foil to be content be 99.99% high purity aluminium foil, claim light paper tinsel.Light paper tinsel is through electrochemical production flow process, corrosion reaming is carried out to aluminium foil, to increase, aluminium foil surface is long-pending forms etched foil, etched foil is again under powerful DC electric field effect, in the electrolytic solution of specified temp, carry out pre-treatment, one-level change into, secondary changes into, three grades change into, level Four changes into, Pyatyi changes into, pyroprocessing, Passivation Treatment, cleaning, the Production Flow Chart such as oven dry, form fine and close dielectric oxide film (Al
2o
3), obtain Waste Acid From Hua Cheng Foil.
The quality standard of aluminium electrolutic capacitor Waste Acid From Hua Cheng Foil is mainly distinguished with the opering characteristic of electric apparatus, mechanical characteristics and appearance characteristics and is come to a conclusion, and the Waste Acid From Hua Cheng Foil of high-quality must meet above-mentioned three technical qualification simultaneously.
Waste Acid From Hua Cheng Foil is very thin, and thickness is micron-sized, and its thickness is generally about 1um, and hole or breakage etc. appear in so thin thickness, directly can have influence on the unit for electrical property parameters of Waste Acid From Hua Cheng Foil or cause Waste Acid From Hua Cheng Foil to be scrapped.In the production process of Waste Acid From Hua Cheng Foil, because the reason of equipment and electrolytic solution is the easiest at appearance qualities such as the generation of Waste Acid From Hua Cheng Foil surface hole, cut, breaches.Therefore, appearance characteristics, for Waste Acid From Hua Cheng Foil, is very important quality metric.
Existing Waste Acid From Hua Cheng Foil production stage mainly comprises: pre-treatment → level Four or Pyatyi change into → pyroprocessing → change into again → and the step such as aftertreatment → cleaning → oven dry → heating → circulation → transmission → filtration.Figure 1 shows that the schematic diagram of the electrolytic bath of existing Waste Acid From Hua Cheng Foil production unit, Waste Acid From Hua Cheng Foil 1 by transmission mechanism respectively through multiple electrolytic bath 2, transmission mechanism comprises cylinder 3 and bottom roll 4, wherein bottom roll 4 is fixedly installed in electrolytic bath 2 by conductive plate 5, electrolytic solution 6 is filled in electrolytic bath 2, Waste Acid From Hua Cheng Foil 1 is positioned between cylinder 3 and bottom roll 4, and is driven by upper cylinder 3 and bottom roll 4 and run incessantly.
Waste Acid From Hua Cheng Foil positively charged, change into tank liquor (temperature is about 85 DEG C) electronegative, Waste Acid From Hua Cheng Foil runs continuously under the drive of transmission mechanism, and Waste Acid From Hua Cheng Foil, under powerful DC electric field effect, forms fine and close dielectric oxide film (Al at aluminium foil surface
2o
3), after cleaning, drying, namely become Waste Acid From Hua Cheng Foil.Electrolytic solution for the production of Waste Acid From Hua Cheng Foil is made up of after high temperature (about 85 DEG C) dissolves boric acid, phosphoric acid, hexanodioic acid, because boric acid, phosphoric acid and hexanodioic acid are originally solid, although through 85 DEG C of dissolvings, dregs residual in boric acid, phosphoric acid and hexanodioic acid are not easy to dissolve.In addition, when the temperature because of electrolytic solution changes, particularly when the temperature is low, the boron phosphoric acid in electrolytic solution and hexanodioic acid there will be crystalline polamer.
The paper tinsel face of Waste Acid From Hua Cheng Foil is close to cylinder and bottom roll operation, when in electrolytic solution, these dregs particles, xln can fall between Waste Acid From Hua Cheng Foil and bottom roll, these dregs particles and xln are along with the rotation of bottom roll, be easy to cause the problem of appearance such as pit, hole print, breach to the surface of Waste Acid From Hua Cheng Foil, paper tinsel face will be exposed by severe patient.Although have filtering system outside electrolytic bath, because dregs, particle produce in groove, electrolytic bath electrolyte inside be do not arrhea dynamic, so these dregs particles and xln cannot be filtered out.Once there is this phenomenon and problem, the quality of Waste Acid From Hua Cheng Foil will be had a strong impact on, even cause Waste Acid From Hua Cheng Foil to become item for disposal and scrap, increase manufacturing cost.If the product of some bad orders flows in Capacitor manufactures hand, easily caused by this product manufacturing electrical condenser out and puncture and affect end equipment safety, harm is very huge.
