Abstract
The invention discloses a manufacturing method for electrolytic capacitor anode foil. The method comprises the steps of cleaning corroded foil with the purity of 99.99%, performing formation in 5 mol of an acetic acid solution for 20-30 minutes at 10-12 DEG C under the current density of 10-40 mA.cm<2>, taking out the foil, and washing the foil with water; performing formation in 5 mol of a boric acid solution for 30-40 minutes at 35-40 DEG C under the current density of 10-30 mA.cm<2>, taking out the foil, and washing the foil with the water; performing heat treatment for 1 minute at 550-600 DEG C; performing treatment in 4 mol of a phosphoric acid solution for 3 minutes at 35-40 DEG C, taking out the foil, and washing the foil with the water; performing heat treatment for 1 minute at 550 DEG C; supplementing anodic oxidation for 3 minutes under 200V; dipping the foil in 3 mol of a formic acid solution for 1 minute; taking out the foil and washing the foil with pure water; and drying the foil at 150 DEG C, thereby obtaining the electrolytic capacitor anode foil.
Description
Technical field
The invention belongs to a kind of electrode foil preparation method.
Background technology
Electrode foil is the key raw material that aluminium electrolutic capacitor manufactures.Due to developing rapidly of electronic industry, the most logical
The drastically expansion in the machine product markets such as letter product, computer, household electrical appliances, simultaneously because the miniaturization of aluminium electrolutic capacitor, Gao Xing
Energyization, chip type requirement more and more urgent, light paper tinsel surface corrosion just becomes electrode paper tinsel after processing and reoxidizing process；Electrode
Paper tinsel quality it is critical only that preparation method chemical synthesis technology condition.
Summary of the invention
It is an object of the invention to, propose a kind of electrolytic capacitor anode aluminum foil manufacture method.
The electrolytic capacitor anode aluminum foil manufacture method of the present invention, it is characterised in that: comprise the following steps:
Learn from else's experience excessive erosion, purity be 99.99% etched foil be carried out after, in 5mol acetum, 10～12
DEG C, electric current density is 10～40mA.cm-2Carry out being melted into 20～30 minutes, take out washing；
In 5mol boric acid solution, 35～40 DEG C, electric current density is 10～30mA.cm-2Carry out being melted into 30～40 minutes, take
Go out washing；
At temperature is 550～600 DEG C, heat treatment 1 minute；
In 4mol phosphoric acid solution, 35～40 DEG C, process 3 minutes, take out washing；
Heat treatment is carried out 1 minute at 550 DEG C；Supplement anodic oxidation, 3 minutes time under 200V；
Impregnate 1 minute at 3mol formic acid solution；After taking-up, pure water cleans；Dry at 150 DEG C, obtain product.
Compared with prior art it provides the benefit that the present invention: technical conditions science, rationally, has that loss is low, folding
Curved good, pressure rising time is short, resistance to hydration performance is good feature.
