Magnesium anode: main functions: extremely high electrochemical function, average anode consumption, long life, large power generation per unit mass, is an ideal sacrificial anode material, suitable for the cathodic protection of metal structures in soil and fresh water media.

In the process of cathodic protection, the anode consumption is average, so the service life is longer. In the actual use process, the actual measured working potential is between -1.8~-1.85V, so the protection effect on the target structure is more significant. At a resistivity above 8000 ohms. For meters of soil, it is recommended to use a high potential magnesium anode.

Application: In sacrificial anode cathodic protection methods, magnesium anodes can be used for resistivity up to 20 ohms. A soil or freshwater environment of m to 100 o. m. In the natural world, most metals exist as compounds. It is through refining that it is energized to change from an ionic to an atomic state. However, the return to its natural state is inherent in the nature of metals. The process by which a metal reacts with a nearby electrolyte to change from an atom to an ion is called erosion.

The basic principle of cathodic protection is to add a large number of electrons to the metal, so that the protected metal as a whole is in a state of excess electrons, so that the metal points reach a unified negative potential, and the metal atoms do not easily lose electrons and become ions dissolved into the solution. There are two ways to achieve this goal, namely sacrificial anode cathodic protection and impressed current cathodic protection. So in order to prevent erosion of the water line, we use sacrificial anodes to prevent erosion, and magnesium anodes can do that. Thus it is known that the magnesium anode in the water pipe is corrosion-resistant.
