Title:
ELECTROLYTIC TREATMENT METHOD AND ELECTROLYTIC TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/038812
Kind Code:
A1
Abstract:
Provided are an electrolytic treatment method and an electrolytic treatment device which apply an alternating current to an upstream electrode (6A) and a downstream electrode (6B) disposed along a transfer direction (a) to subject an aluminum web (W) to electrolytic treatment, wherein at least one of a transfer rate (f) of the aluminum web (W), a frequency (f) of the alternating current to be applied to the upstream electrode (6A) and the downstream electrode (6B), or a web transfer distance (d2) between the upstream electrode (6A) and the downstream electrode (6B) is set so that an alternating-current voltage waveform to be applied to the aluminum web (W) at the end of the upstream electrode (6A) and an alternating-current voltage waveform to be applied to the aluminum web (W) at the tip of the downstream electrode (6B) adjacent to the downstream side of the upstream electrode (6A) are not overlapped each other.
