Preparing method of sacrificial anode alloy for electrolytic protection and electrolytic protection method using sacrificial anode

摘要

The present invention relates to a method of manufacturing a sacrificial anode alloy for electric corrosion and an electrical corrosion method using the sacrificial anode, and more particularly, to a method of manufacturing a sacrificial anode alloy for electrical corrosion, including zinc, aluminum, copper, and magnesium, And it relates to an electric method for preventing electrical corrosion of a steel structure excreted underground or underwater by using the sacrificial anode. The present invention provides a method of manufacturing a sacrificial anode alloy for electric corrosion and an electric corrosion method using the sacrificial anode, thereby effectively suppressing the corrosive action of steel structures or pipes used in high-resistance atmospheres such as ground, underground, freshwater, and seawater. In addition, compared to the existing magnesium anode and aluminum anode, there is an effect that can be used even under higher electrolyte resistivity conditions.
