Benefits of technology

The patent describes a way to make a drum electrode that can be easily plated with metal and maintained during use. This method can be used for plating, resin molding, and metal porosity production.

Problems solved by technology

Consequently, current efficiency is decreased, and furthermore, since it is difficult to remove the metal electrodeposited on the surface of the drum electrode, it becomes necessary to periodically replace the drum electrode.

example 1

[0096]1>

[0097]24 Disks made of aluminum with a thickness of 1 mm and a diameter of 200 mm were prepared, and a through-hole with a diameter of 40 mm was formed in the center of each of the disks.

[0098]25 Insulating disks made of vinyl chloride with a thickness of 4 mm and a diameter of 199 mm were prepared, and a through-hole with a diameter of 40 mm was formed in the center of each of the disks.

[0099]The disks made of aluminum and the insulating disks were alternately arranged and fixed firmly with bolts. A power feeding layer made of titanium with a diameter of 39 mm and a length of 250 mm was inserted into the through-hole portion in the center, and fixed firmly with a jig. Thus, a drum electrode 1 was obtained, in which linear projecting electrodes continuously extending in the circumferential direction with a width of 1 mm were formed at an interval of 4 mm.

[0100]The projecting electrodes of the drum electrode 1 thus obtained were subjected to aluminum plating treatment in orde...

[0110]2>

[0111]A drum made of aluminum with a diameter of 200 mm was prepared, and 24 linear projections extending continuously in the circumferential direction were formed at an interval of 4 mm. The width of the projections was set at 1 mm, and the height of the projections was set at 1.5 mm.

[0112]The entire surface of the aluminum drum was coated with a fluororesin (ETFE) with a thickness of 0.6 mm. Since the fluororesin layer was also formed on the surfaces of the projections, the surface coated with the fluororesin was scraped until the surfaces of the projections were exposed. Aluminum plating was grown with a thickness of 0.5 mm on the surfaces of the projections (aluminum) exposed from the surface of the fluororesin. Thus, a drum electrode 2 was obtained, in which linear projecting electrodes 63 continuously extending in the circumferential direction with a width of 1 mm were formed at an interval of 4 mm. FIG. 6 is an enlarged cross-sectional view of a surface portion of the...

[0115]3>

[0116]A drum made of aluminum with a diameter of 200 mm was prepared, and by subjecting the surface thereof to anodic oxide coating treatment, an anodic oxide film of aluminum was formed. The thickness of the anodic oxide film of aluminum was about 10 μm.

[0117]On the surface of the drum on which the anodic oxide film had been formed, 24 grooves continuously extending in the circumferential direction were formed at an interval of 4 mm. The width of the grooves was set at 1 mm, and the depth of the grooves was set at 0.5 mm. By subjecting the surface of the drum to aluminum plating treatment, aluminum plating was grown in the grooves. Aluminum plating was formed so as to project from the surface of the anodic oxide film by 0.5 mm. Thus, a drum electrode 3 was obtained, in which linear projecting electrodes 73 continuously extending in the circumferential direction with a width of 1 mm were formed at an interval of 4 mm. FIG. 7 is an enlarged cross-sectional view of a surface p...

Abstract

A drum electrode, which is used for a device configured to plate a surface of a long base material having electrical conductivity with a metal, includes a power feeding layer, an insulating layer which covers a surface of the power feeding layer, and a projecting electrode which projects from the surface of the insulating layer and is electrically connected to the power feeding layer, in which the projecting electrode is provided linearly in the circumferential direction of the drum electrode.

Description

TECHNICAL FIELD[0001]The present invention relates to a drum electrode which is used for plating the surface of a resin molded body having a three-dimensional network structure with a metal in a plating tank. The invention further relates to a method for producing the drum electrode, and a plating device, a method for producing a resin molded body, and a method for producing a metal porous body, each using the drum electrode.BACKGROUND ART[0002]In recent years, metal porous bodies having a three-dimensional network structure have been widely used in electrodes of batteries, various filters, catalyst carriers, and the like. A metal porous body is generally obtained by imparting electrical conductivity to the surface of a resin molded body having a three-dimensional network structure, such as foamed urethane or foamed melamine, electroplating the surface of the resin molded body with a metal, and then removing the resin molded body by heat treatment or the like.[0003]In the case where...
