HOLLOW ELECTRODE WITH FILM FOR ELECTRODEPOSITION COATING

摘要

For solving the problems of reduction of coating resin accompanying the advance of electrodeposition coating treatment and, as a consequence thereof, pinhole occurrence and coating film re-dissolution attributed to an increase of electrolyte concentration, it is intended to avoid any increase of part count and enlargement of hollow electrode with film having a diaphragm, such as an ion exchange membrane, assembled therein. In order to realize the above, diaphragm (20), such as an ion exchange membrane, is fitted on the external surface of, as a support, electrode main body (10) produced by working a conductive material into a hollow form so as to realize a structure allowing free passage of liquid between the inside and outside thereof.
