Prepackaged Magnesium Anodes are integrated cathodic protection assemblies combining a magnesium alloy anode core with specialized encapsulation materials. This pre-assembled configuration incorporates the anode, backfill materials, and connection components, eliminating on-site assembly steps and reducing installation time by 30–50%.
The engineered backfill formulation (e.g., gypsum powder + bentonite) maintains a humid microenvironment around the anode, decreasing ground resistance by 15–40% and enhancing current output efficiency by ≥20%. Simultaneously, the backfill isolates soil contaminants (e.g., chlorides, sulfides), reducing anode consumption rates by 25–35% and extending service life to 15–30 years in typical soil environments.
