Magnesium alloy sacrificial anode is a corrosion control material used for cathodic protection, featuring a more negative corrosion potential and high current efficiency compared to the protected metal. This material is primarily used for protecting metal structures in soil and freshwater environments. Its characteristics include excellent electrochemical performance, uniform anode consumption, long service life, and high electrical output per unit mass. Magnesium alloy sacrificial anodes are suitable for soil or freshwater environments with resistivity ranging from 20 ohm-meters to 100 ohm-meters. Parameters such as design life, current efficiency, theoretical electrical capacity, and anode utilization rate demonstrate its superiority as a sacrificial anode material. Additionally, magnesium alloy sacrificial anodes have a low specific gravity, relatively negative potential, high driving voltage for iron, and low current efficiency, making them particularly suitable for high-resistivity media.

Installation Methods for Magnesium Alloy Sacrificial Anodes mainly include the following steps:

1. Selection of Magnesium Anode: Choose the appropriate magnesium anode based on the engineering environment and facility characteristics. Common types of magnesium anodes include hanging magnesium anodes, buried magnesium anodes, and immersed magnesium anodes. Different types of magnesium anodes are suitable for different environmental conditions and equipment structures, so selection should be made according to actual conditions.
2. Pre-installation Preparation: Inspect the corrosion condition and existing issues of the facility, and determine the installation locations and quantity. Clean the surface of the facility to ensure it is smooth and free of dirt, guaranteeing good contact between the magnesium anode and the facility. Prepare the necessary tools and materials for installation, such as screwdrivers, bolts, washers, etc.
3. Installation Process: Mark the installation points on the facility surface based on the selected locations. Place the magnesium anode at the marked positions and secure it with a screwdriver or bolts. Ensure the magnesium anode fits tightly against the facility surface without any looseness or protrusion.
4. Post-installation Treatment: Check whether the installed magnesium anode is secure and make necessary adjustments. Apply anti-corrosion spray to the contact surfaces around the magnesium anode to enhance corrosion protection. Clean the installation site to maintain the facility's tidiness.
5. Regular Inspection and Maintenance: Installing magnesium anodes is only part of corrosion protection work; regular inspection and maintenance are equally important. It is recommended to inspect the magnesium anode periodically and replace or adjust it based on actual conditions. At the same time, regularly clean the facility surface to remove dirt and biological attachments, ensuring the magnesium anode's effectiveness.
