Title:
電解銅箔製造用のチタン製カソード電極、そのチタン製カソード電極を用いた回転陰極ドラム、チタン製カソード電極に用いるチタン材の製造方法及びチタン製カソード電極用チタン材の矯正加工方法
Document Type and Number:
Japanese Patent JP4441642
Kind Code:
B2
Abstract:
The purpose is to provide a cathode electrode for manufacturing an electrodeposited copper foil which is possible to be continuously and stably usable for a long duration of 3000 hours or longer to subsequently lessen the frequency of maintenance work execution as low as possible and to contribute to lower the running cost of the electrodeposited copper foil manufacture. As the means for achieving the purpose, a cathode electrode made of a titanium material is employed for obtaining an electrodeposited copper foil using an electrolytic copper solution and the titanium material having 7.0 or higher crystal grain size number and 35 ppm or lower initial hydrogen content is used for manufacturing the cathode electrode for manufacturing an electrodeposited copper foil. Further, also provided is a manufacturing method of the titanium material to be employed for the cathode electrode made of a titanium material.
