Corrosion device for improving corrosion performance of corrosive aluminum foil

Abstract

The invention relates to the technical field of corrosive aluminum foil processing, in particular to a corrosion device for improving the corrosion performance of a corrosive aluminum foil. The corrosion device for improving the corrosion performance of the corrosive aluminum foil comprises a corrosion tank and the aluminum foil, wherein hydrogen collecting belts are arranged on the inner side and the outer side of the aluminum foil respectively, and metal palladium wires or metal platinum wires are arranged on the hydrogen collecting belts respectively. For the corrosion device disclosed by the invention, hydrogen on the surface of the aluminum foil and in corrosion holes is taken away through the adsorption effect of the metal palladium wires or the metal platinum wires on the hydrogen, and then the metal palladium wires or the metal platinum wires are heated to a certain degree, so that the hydrogen is separated from the metal palladium wires or the metal platinum wires and then is recycled.

Problems solved by technology

[0007] However, there is such a problem in the prior art that because hydrogen is a diamagnetic substance in weakly magnetic substances, the degree of magnetization by an external magnetic field is very low, and the movement of the aluminum foil in the corrosive liquid and the flow of the corrosive liquid itself will produce various in the liquid. The turbulent flow in the direction, the probability of hydrogen leaving the surface of the aluminum foil and the corrosion hole is low, and most of the hydrogen cannot be degassed by the magnetic field. Therefore, the existing technology uses the magnetic effect of the magnetic field on the hydrogen to improve the aluminum foil. The inefficiency of the capacitive performance of the

[0008] On the other hand, hydrogen gas is insoluble in water and will escape from the corrosion solution, thus accumulating in the space above the corrosion tank. When the concentration of hydrogen gas reaches a certain level, there is a danger of combustion and explosion. At the same time, the escaped hydrogen gas cannot Recycling also causes waste of energy
