14D2-2 High Potential Magnesium Anode For Cathodic Protection Mg 6.35kg
Uniform Surface Dissolution High Potential Magnesium Anode For Cathodic Protection
Introduction:
Mg-Mn sacrificial anodes are common binary high-potential alloys, in which Mn element in the alloy can make the second phase distribution uniform, promote grain refinement, and improve its electrochemical performance. Mg-Mn alloy with low Mn content, the influence of Mn content on its microstructure and electrochemical properties was analyzed, the appropriate amount of Mn added (0.08%~0.4%) was determined, and impurities in the Mg-Mn sacrificial anode were found. Elements can cause large solute segregation and obvious grain size differences, so reducing impurity elements is the preferred method for performance improvement.

Advantage:
Cathodic protection technology is to use a metal or alloy whose potential is more negative than the metal to be protected to be electrically connected to the metal to be protected, and rely on the current generated by the continuous corrosion and dissolution of the metal with a negative potential to protect others.
A: The one-time investment cost is low, and there is basically no need to pay maintenance costs during operation
B: The utilization rate of the protection current is high, and no over-protection will occur
C: No interference effect on adjacent underground metal facilities, suitable for plant area and long-distance pipeline without power supply, as well as small-scale decentralized pipeline protection
D: It has the function of both grounding and protection
E: The construction technology is simple and usually does not require special professional maintenance and management.
Application:
Magnesium anode is the use of magnesium negative potential, its potential is lower than steel, can be used to protect onshore pipelines and other buried structures, such as oil pipelines, natural gas pipelines, underground oil tanks, oil platforms, water heaters, and for the protection of fresh water ships in the environment.
