Description

Production equipment for medium-high voltage anode foil

Technical Field

The utility model discloses medium and high voltage aluminium foil production field, concretely relates to production facility of medium and high voltage anode foil.

Background

The anode foil is a key material of the aluminum electrolytic capacitor and plays a role in determining the capacity index of the capacitor. With the rapid development of the information industry and the integration and miniaturization of electrical products, the demand of small-volume and large-capacity aluminum electrolytic capacitors is driven, and therefore, the improvement of the electrostatic capacity of the anode foil is urgently needed.

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.

The process of primary hole forming and secondary hole expanding is slow, so that the production speed of the existing production line is limited, and the production efficiency is low; in addition, at present, the constant current adopted for corrosion of the hair holes is the most common in China, the constant current power-up curve adopted by the corrosion process is adopted, and in the hair hole corrosion process, due to the fact that the applied current value is large, the aluminum foil is always in the process of hole initiation and hole growth in the whole power-up period, and the obtained corrosion foil tunnel hole is poor in length uniformity. Moreover, because the aluminum foil is always in a pore-forming state when the constant-current pore-forming corrosion is adopted, the number of ineffective short pores generated subsequently is increased, and a large number of parallel pores are formed on the surface of the aluminum foil, so that the aluminum foil is thinned, and the mechanical strength of the electrode foil is reduced; the corrosion liquid in the chemical corrosion device adopted at present is static, and when the optical foil is corroded, the components in the corrosion liquid are gradually and unevenly distributed along with the progress of corrosion, so that the corrosion effect of the optical foil is gradually reduced, and the overall corrosion effect is uneven; the cleaning liquid in the chemical cleaning device adopted at present is static, and the cleaning of the optical foil is only carried out once from the cleaning liquid, which is equivalent to soaking; this results in the surface of the foil remaining and the tunnel-type etching holes in the foil not being cleaned.

Based on the situation, the utility model provides a production facility of well high voltage anode foil can effectively solve above problem.
