OEM High Potential Magnesium Anode 32 Lb For Gas Tank

Long Service Life High Potential Magnesium Anode For High Resistivity Environment
 
Introduction:
 

Magnesium is an active metal, and its electrochemical properties are greatly affected by impurities and alloying elements. When it contains a small amount of impurities, especially impurities with low hydrogen evolution overpotential, the autolysis tendency of magnesium will increase, and the current efficiency will decrease.

Some impurity elements in magnesium, such as Fe, Co, Mn, are solid-dissolved in the magnesium matrix in the form of elemental substances, while other impurities, such as Al, Zn, Ni, Cu and other elements, are easy to form intermetallic compounds with magnesium, No matter what kind of impurity elements, they all show strong cathodic properties relative to magnesium solid solution, which can increase the effective area for hydrogen evolution and further increase the corrosion rate of magnesium.

It is necessary to reduce the content of impurity elements in pure magnesium anodes as much as possible. The mass fraction (%) of impurity elements should be controlled at: Zn<0.03, Mn<0.01, Fe<0.02, Ni<0.001, Cu<0.001, Si<0.01.

But this brings difficulties to the production of pure magnesium anodes. Generally, the alloying method is used, and a certain amount of alloying elements such as Mn, Al, Zn, etc. are added to industrial magnesium, which can eliminate the adverse effects of impurity elements and obtain magnesium alloy sacrificial anode materials with excellent performance.

Features:

The main characteristics of high-potential magnesium alloy sacrificial anodes are large electricity per unit mass, high potential, small specific gravity, negative potential, high driving voltage to Fe, low current efficiency, etc., especially suitable for high resistivity media. When using magnesium alloy sacrificial anode, care should be taken to avoid collision with steel structure. American standard ASTM8431993 (2003) and Chinese standard GB/T177312004 both require the current efficiency of high-potential magnesium alloy sacrificial anodes to be higher than 50% and the potential higher than 1.77 V.

Application:

Applicable to anti-corrosion protection of the oil, gas, water supply and drainage pipelines, as well as the protection of harbor, ship, resevoir, gate and other projects in water.
