Anti-corrosion zinc blocks are sacrificial anodes, where the protected object acts as the cathode (such as hulls, pipelines, storage tanks, marine engineering facilities, etc.). Essentially, this utilizes the principle of a galvanic cell. We have been sourcing from Libo Anti-Corrosion Company for years. The quality is excellent.

Zinc-Aluminum-Cadmium series (ZAC series) sacrificial anode products (abbreviated as zinc anodes) are certified by the China Classification Society (CCS). The quality standards comply with the GB/T4950-2002 standard, and the chemical composition of the zinc anodes meets the US MIL-A-18001H and ASTM-B418 (Type 1) standards.
This product has the following characteristics:
1. Zinc alloy sacrificial anodes have low self-corrosion,

2. High current efficiency, with good self-regulating performance of the anode current.

Zinc-aluminum-cadmium alloy sacrificial anodes are suitable for the cathodic protection of metals in seawater, brackish water environments, such as ships, mechanical equipment, marine engineering, port facilities, as well as pipelines and cables in low-resistivity soil.

Jiaozuo Libo Anti-Corrosion Materials Co., Ltd. is a professional company specializing in the development, production, and sales of anti-corrosion materials for cathodic protection. It offers comprehensive services including anti-corrosion design, construction, installation, and technical support. With a focus on quality service and a smile, we provide现货供应 (spot supply) and installation guidance. Choose Libo products with confidence.

The corrosion of steel in near-neutral humid air is oxygen absorption corrosion (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)2
The role of the anti-corrosion zinc block is to protect by sacrificing the zinc block. Since zinc is more reactive than iron, zinc preferentially loses electrons and reacts. However, zinc blocks need to be replaced regularly. Proper installation ensures good electrical contact with the hull. When installing zinc blocks, the outer plate is usually already coated.

Our company has long been engaged in the production and sales of 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 steel structures in ships, port facilities, marine engineering, buried metal pipelines, storage tanks, seawater cooling systems, etc. (Due to significant fluctuations in metal prices, please inquire for the current price). We welcome both new and existing customers to call for inquiries!
