Title:
アルミニウム箔の製造方法
Document Type and Number:
Japanese Patent JP6919247
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a production method of electrolytic aluminum foil that can prevent the foil from having scorch and/or damage.SOLUTION: Part of the outer periphery of a cathode drum and an anode member are immersed in an electric aluminum plating solution that is warmed up to a predetermined temperature available for plating processing. By applying an electric current between the cathode drum and the anode member, and by rotating the cathode drum, aluminum is electrodeposited in the electrodeposition area of the outer periphery of the cathode drum to form an aluminum film. In a production method of aluminum foil, the aluminum film that gradually rises from the liquid surface of the plating solution is exfoliated from the cathode drum. When the rotating cathode drum is heated and the electrodeposition area of the cathode drum where the aluminum film is exfoliated approaches into the plating solution, the whole of the electrodeposition area in the axial direction of the cathode drum approaches in a state in which the plating solution is heated up to the temperature available for plating processing.SELECTED DRAWING: Figure 1
