Anti-corrosion zinc anodes are sacrificial anodes, where the protected object acts as the cathode (such as hulls, pipelines, storage tanks, offshore engineering facilities, etc.). This essentially 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 (referred to 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.

Men need beauty, hulls need zinc anodes

Many electrochemical phenomena occur in daily life, such as the rusting of steel, especially when metals come into contact with water, rusting accelerates. This is essentially an electrochemical reaction.
It is a chemical reaction occurring on the metal surface, forming a micro-cell, also known as a corrosion cell (its electrodes are conventionally called the cathode and anode, not positive and negative poles). Oxidation occurs at the anode, causing the anode to dissolve, while reduction occurs at the cathode, generally only facilitating electron transfer. When dissolved in this layer of water film, it forms an electrolyte solution, and the metal immersed in this solution is always impure. For example, industrial steel is actually an alloy, containing not only iron but also graphite, cementite, and other metals and impurities, most of which are less reactive than iron. In this way, the anode of the corrosion cell is iron, and the cathode is the impurity. Since iron and impurities are in close contact, corrosion continues.
Ships sailing in seawater experience even more severe electrochemical corrosion because seawater contains free ions, making it a natural electrolyte. The reaction between metal and electrolyte involves cathode and anode reactions. When two different metals are placed together, the more active metal tends to lose electrons. The medium for this exchange is the electrolyte, which contains free ions. When iron is in an acidic electrolyte solution, it loses electrons, and impurities become the positive pole. Hydrogen ions in the solution absorb electrons and evolve as hydrogen gas. This corrosion process is called hydrogen evolution corrosion due to the release of hydrogen gas. In less acidic environments, the following chemical reaction occurs, which is the reaction at the positive pole of the micro-cell. This corrosion process is called oxygen absorption corrosion because it involves the absorption of oxygen.
