Product Description: Hull Commonly Used Sacrificial Anode Zinc Block ZH-1Zinc-aluminum-cadmium alloy sacrificial anodes are suitable for the cathodic protection of metals against corrosion in seawater, brackish water media for ships, mechanical equipment, marine engineering, and port facilities, as well as for pipelines, cables, and other installations in low-resistivity soil.Jiaozuo Libo Anti-Corrosion Materials Co., Ltd. is a professional company integrating the development, production, and sales of anti-corrosion materials for cathodic protection, along with comprehensive anti-corrosion design, construction, installation, and technical services. With excellent service quality and a smile, we offer现货供应 installation guidance. Choose Libo products with confidence for放心选购.The corrosion of steel in near-neutral humid air属于吸氧腐蚀 (the same applies in seawater):Negative electrode (Fe): 2Fe - 4e = 2Fe2+Positive electrode (C): 2H2O + O2 + 4e = 4OH-Overall reaction equation: 2Fe + O2 + 2H2O = 2Fe(OH)2The role of attaching anti-corrosion zinc blocks is to protect by sacrificing the zinc block. Since zinc is more reactive than iron, zinc优先失去电子 and reacts first. However, zinc blocks need to be replaced regularly. Proper installation ensures good electrical contact with the hull. When installing zinc blocks, the outer hull is usually already painted.Hull Commonly Used Sacrificial Anode Zinc Block ZH-1 Our company has long been producing and selling zinc blocks, zinc anodes, sacrificial anodes, magnesium anodes, aluminum anodes, zinc alloy anodes, etc. Welcome your patronage! Our products are widely used for the cathodic protection of ships, port facilities, marine engineering, buried metal pipelines, storage tanks, seawater cooling water systems, and other steel structures (Due to fluctuating metal prices, please inquire for the current price).

It is well-known for protecting ship hulls, boilers, and the outer walls of internal combustion engine cylinders. However, further exploration into materials and installation has only occurred in the last 20 years. During this time, technologically advanced countries like the United States have made improvements in materials and dimensions, while China has also continuously achieved results in research on zinc for impressed current anodes. The performance of anti-corrosion zinc with微量添加镉 and aluminum has become increasingly effective, with these studies based on high-purity zinc. The principle is sound: zinc corrodes before iron, and ships in the ocean also附带锌块. However, this is feasible during use for your own vehicle, but it would be more complicated for manufacturers to implement this approach.
