FORMING METHOD OF SACRIFICIAL ANODE BODIES FOR PREVENTING CORROSION USING MAGNET WITHOUT LEAVING MARKS AND FLAWS ON STEEL AND METAL STRUCTURE

摘要

PURPOSE: To easily install and dismantle the sacrificial anode bodies and prevent damage of the steel and metal structure by connecting magnet to the sacrificial anode bodies in such a way that Al anode, Zn anode and Mg anode, sacrificial anode bodies used in sacrificial anode method in electrochemical protection for preventing corrosion of steel and metal structure, are easily attached to and detached from the steel and metal structure without marks and flaws. CONSTITUTION: The forming method comprises the processes of molding zinc, aluminum and magnesium used as sacrificing anode material used instead of a steel structure into a sacrificing anode body (3) comprising a magnet insertion port (2) on which a screw part (1) is formed, and inserting a magnet (4) on which a screw part is formed into the magnet insertion port, wherein the sacrificing anode body and the magnet are connected to each other by a means for fixing the magnet into the sacrificing anode body molded in such a way that a magnet on which a hook is formed is connected to the sacrificing anode body, and wherein the sacrificing anode body and the magnet are connected to each other by forming the magnet in such a shape that the magnet covers the sacrificing anode body after forming a space part in the magnet into which the sacrificing anode body is inserted if thickness of the sacrificing anode body is thin.
