WASHING SYSTEM FOR ELECTRODEPOSITION COATED MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a washing system for an electrodeposition coated material by which generation of air bubbles accumulated on the bottom of a washing chamber can be prevented even for a long time washing and the closed system of the washing chamber can be achieved. SOLUTION: The washing system for the electrodeposition coated material has: the washing chamber having the bottom and the sides enclosing the electrodeposition coated material as a material to be subjected to washing; a nozzle which is disposed inside the washing chamber and used for spraying the water for washing against the electrodeposition coated material; a nozzle which is disposed inside the washing chamber and used for directly spraying the water against the air bubbles occurring at the bottom of the washing chamber; a storage tank for storing the water recovered from the washing chamber; and a means of feeding the water in the storage tank to the nozzles.
