Definitions
- a tubular diaphragm support member is arranged concentrically at a predetermined interval around the tubular electrodeposition electrode.
- a diaphragm such as an ion exchange membrane is mounted on the outer surface of the diaphragm support member, and water is supplied to the annular gap formed between the electrode and the diaphragm support member through the inside of the electrode.
- Patent Documents 1 and 2 describe an electrode device that selectively introduces an electrolyte (polar solution) existing outside the diaphragm into the annular gap and discharges it to the outside.
- a membrane such as an ion exchange membrane disposed with a gap outside the tubular electrode may swell and expand during use, which causes wrinkles or wrinkles in the membrane.
- problems such as inadequate fixing to suppress the problem.
- the generation of wrinkles in the diaphragm caused accumulation of the oil component in the coating liquid, which in turn caused poor coating such as pits.
- the hollow electrode body also serves as a support for the diaphragm by being configured so that liquid can freely pass between the inner side and the outer side.
- a diaphragm such as an ion exchange membrane is directly attached to the outer surface of the electrode body that also serves as the support.
- surplus electrolyte (polar solution) in the coating liquid is collected in the electrode body through the diaphragm.
- a dedicated support member for holding the diaphragm on the outside of the electrode becomes unnecessary, and an annular gap between the electrode and the support member is eliminated.
- FIG. 1 shows an embodiment of the present invention. It is a longitudinal cross-sectional view of the hollow electrode with the film
- the membrane-coated hollow electrode of the present embodiment is used as, for example, a tubular anode in cationic electrodeposition coating.
- the hollow electrode includes a cylindrical electrode body 10 that is installed vertically, a cylindrical diaphragm 20 that is in close contact with and holds the outer surface of the electrode body 10, and an end cap that closes the lower end of the electrode body 10. 30, a top cap 40 that closes the upper end portion of the electrode body 10, and a cap case 50 for sealing that covers the upper end portion of the electrode body 10 together with the top cap 40.
- the supply hose 61 and the discharge hose 71 do not easily bend and need to have a certain degree of strength, and may be a hose containing a reinforcing mesh to increase pressure resistance.
- the connection between the introduction nozzle 60 and the supply hose 61 and the discharge nozzle 70 and the discharge hose 71 is preferably performed inside the cap case.
- the hollow electrode when used for cationic electrodeposition coating, the hollow electrode is disposed along the side walls on both sides in an electrodeposition tank containing a coating liquid.
- the electrode body 10 of the hollow electrode is used as the anode, and the object to be coated, which is the cathode, moves through the coating liquid in the electrodeposition tank so as to pass between the electrode arrays on both sides.
- positively charged paint grease adheres to the surface of the object. Since the ionization degree of the coating resin is weak, an acidic electrolyte (polar solution) such as acetic acid is mixed in the coating liquid.
- the fabricated hollow electrode has the structure shown in FIG.
- FIG. 1 is a longitudinal sectional view of a hollow electrode with a film for electrodeposition coating showing an embodiment of the present invention.
