Description

Technical Field

[0001] The utility model relates to the technical field of sacrificial anodes, in particular to a marine sacrificial anode protection device. Background Art

[0002] Sacrificial anode technology is widely used in the corrosion protection industry and is an effective method for metal corrosion prevention. Its basic principle is to use a highly reducing metal as a protective electrode, connected to the protected metal via a conductive medium to form a galvanic cell. In this galvanic cell, the highly reducing metal, acting as the anode, undergoes an oxidation reaction and is gradually consumed as electrons flow out. This allows the protected metal, acting as the cathode, to avoid corrosion. However, when ships sail in the ocean, barnacles, mussels, or other impurities adsorbed on the surface of the sacrificial anode can hinder full contact between the anode and seawater, reducing the effective contact area between the anode and seawater. This slows the dissolution rate of the anode material and reduces the electrochemical protection current.
