Description
The copper-based electrolytic anti-corrosion anode rod is a core electrolytic component in the Marine Growth Prevention System (MGPS). The anode rod electrolyzes seawater to generate trace metal ions (primarily copper ions), creating an antimicrobial environment around the hull that effectively prevents marine organisms from adhering and proliferating on the ship’s hull, pipelines, and cooling water systems. This anode rod features high electrolytic efficiency, controllable consumption rates, and ease of installation and maintenance. It significantly reduces biofouling-induced navigation resistance, fuel consumption, and mechanical corrosion, making it a key antifouling technology for enhancing vessel operational economy and environmental sustainability.
The aluminum-based electrolytic anti-corrosion anode rod is a key component in Marine Growth Prevention Systems (MGPS). Unlike copper anodes which directly kill organisms, its core function is to electrolyze seawater to generate aluminum ions. These ions rapidly form a positively charged aluminum hydroxide colloid in water, which adsorbs uniformly onto the inner surfaces of cooling water pipes, condensers, and heat exchangers, forming a very thin and dense protective film. This film effectively isolates the metal surface from seawater, thereby preventing electrochemical corrosion, while also inhibiting the attachment of marine organism larvae through a physical barrier effect. This achieves dual benefits of corrosion prevention and auxiliary anti-fouling. Its advantages include significantly extending pipeline system lifespan, reducing maintenance frequency, and enhancing the overall protective efficiency of the MGPS.
