Description

High-pressure aluminum foil production equipment

Technical Field

The utility model relates to a high-pressure aluminium foil production field, concretely relates to high-pressure aluminium foil production facility.

Background

With the rapid development of the electronic industry, the application of the aluminum electrolytic capacitor is wider, and the performance requirement is higher and higher. The corrosion formed foil for the aluminum electrolytic capacitor is an electronic main material of basic component products in the electronic information industry, and the aluminum foil market of the medium-high voltage aluminum electrolytic capacitor is short in supply and demand. As a corrosion formed foil for medium and high voltage electrolytic capacitors with rated voltage of more than 200V, the high-voltage electrolytic capacitor has high quality requirement and great production difficulty, and the performance can not meet the use requirement of users, so that the specific volume is required to be continuously improved on the premise of ensuring the bending strength of the corrosion aluminum foil urgently. The electrostatic capacity of the corrosion foil for the anode of the high-voltage electrolytic capacitor is the key for limiting the volume of the high-voltage large-capacity electrolytic capacitor.

It is known that the anode foil capacitance C ═ 0 ∈ rS/d can increase the anode foil capacitance by increasing the anode foil surface area. The anode foil for medium and high voltage is generally formed with tunnel-type etching holes by electrochemical etching to increase the specific surface area, and then formed into an oxide film layer having dielectric properties. The conventional medium-high voltage corrosion process comprises pretreatment, primary hole forming, secondary hole expanding and post-treatment, and firstly, oil stains, an oxide film layer and the like on the surface of a plain foil are removed through the pretreatment; carrying out electrochemical corrosion on the primary hair holes to form tunnel holes with certain hole density and hole depth; the secondary reaming further expands the aperture of the etching hole and increases the capacity of the etching foil; finally, the residual impurities such as chloride ions and the like are removed through post-treatment. The first-level pore-forming corrosion is the key of the corrosion process, the capacity performance of the corrosion foil is determined, and tunnel holes with certain hole density, uniform distribution and consistent hole length are generated by adjusting parameters such as temperature, components, current, electric quantity and the like of corrosion bath solution, so that the aims of improving specific volume and mechanical performance are fulfilled. The control of the uniformity of the etching holes is the key to the performance of the etched foil and also the bottleneck of the etched foil process technology.

In the hole-forming corrosion process, due to the fact that the applied current value is large, the aluminum foil is always in the hole initiation and hole growth process in the whole power-on period, and the obtained etched foil tunnel hole is poor in length uniformity. In addition, because the aluminum foil is always in a hole-forming state when the constant-current hole-forming corrosion is adopted, the number of ineffective short holes generated subsequently is increased, a large number of parallel holes are formed on the surface of the aluminum foil, the aluminum foil is thinned, and the mechanical strength of the electrode foil is reduced. The finished corrosion foil needs to be rolled up finally, and the corrosion foil can shake in the horizontal direction in the rolling process, so that two sides of the corrosion foil roll after being rolled up are uneven finally, and the quality of the corrosion foil is reduced; in the traditional production of high-pressure aluminum foil, the high-pressure aluminum foil directly passes through corrosive solution and is discharged, so that the chemical corrosion time of the high-pressure aluminum foil is short, the corrosion quality is poor, and the corrosion progress cannot be controlled; when a part of high-pressure aluminum foil is subjected to chambering, twice corrosion is needed, and the aluminum foil cannot be conveniently corroded twice by the traditional chambering device.
