Characteristics and application range of magnesium alloy sacrificial anode

Magnesium anode has very high electrochemical function, the consumption of magnesium anode is uniform, the service life is long, the energy generation is large, magnesium anode is suitable for the cathode maintenance of metal structures in soil and fresh water medium. Magnesium anode in the process of cathodic protection, magnesium anode is evenly consumed, so its service life is long. In the process of practical application of magnesium anode, the maintenance of target structure is more obvious. At a resistivity greater than 8000 ohms. For rice soils, magnesium anodes are recommended.

In nature, magnesium anodes exist as metallic compounds. During refining, the magnesium anode is endowed with an ionic state that transforms into an atomic state. The principle of cathode maintenance is that the metal makes up for the electrons, so that the maintained metal is in the state of excess electrons, so that the metal reaches a negative potential, and the metal atoms are not easy to lose electrons and form ions to dissolve into the solution. The method of magnesium anode can be used to avoid corrosion. Magnesium anode plays such a role.
