Title:
アルミニウム箔の製造方法およびアルミニウム箔製造用陰極ドラム
Document Type and Number:
Japanese Patent JP6694578
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing aluminum foil capable of continuously performing an operation from the formation of an aluminum film to its coiling and further capable of suppressing the contact of an aluminum electrolytic solution with moisture in the air, and a cathode drum used for the production of aluminum foil.SOLUTION: Provided is a method for producing aluminum foil where, using a cathode drum where one edge of a copper plating layer formed at least on a part of a cathode drum barrel body is peeled from the barrel body to form copper foil, one edge of the copper foil is fixed to a take-up reel, d.c. current is applied to a space between an anode member immersed into an aluminum electrolytic solution and a cathode drum, while forming an aluminum film on the surface including the other edge of the copper plating layer immersed into the aluminum electrolytic solution, the copper plating layer is peeled from the barrel body so as to be taken up around the take-up reel, further, the aluminum film connected from the copper plating layer and formed on the surface of the barrel body is continuously peeled from the barrel body of the cathode drum and is taken up around the take-up reel.SELECTED DRAWING: Figure 1
