Acid pickling corrosion inhibitor is a chemical used in the process of metal pickling, mainly used to remove oxides, rust, and other pollutants from the metal surface, and to reduce the reaction between the metal and the pickling solution. The following are common types of acid pickling corrosion inhibitors:
Corrosion inhibitor: Corrosion inhibitor can reduce the reaction between metal and acid solution, reducing the corrosion rate of metal. Corrosion inhibitors typically form a protective film on the metal surface to prevent further acidic corrosion.
Surfactants: Surfactants can improve the wettability between pickling solution and metal surfaces, making the pickling solution better cover metal surfaces and improving cleaning efficiency.
Cleaning enhancer: Cleaning enhancer can promote acid washing solution to better dissolve pollutants, reduce residues, and improve cleaning efficiency. They can combine with impurities on the metal surface to help remove them from the metal surface.
Chelating agent: Chelating agent can combine with ions on the metal surface to form a complex, preventing it from reacting with oxidants or other harmful substances in the pickling solution. Chelating agents can reduce the corrosion rate of metals and improve the stability of pickling solutions.
Desert inhibitor: Desert inhibitor can inhibit the catalytic action of iron ions or other metal ions in acid pickling solution, reducing corrosion of metal surfaces. They can achieve corrosion inhibition effects by forming a protective film or engaging in physical or chemical reactions with metal surfaces.
It should be noted that different metals and specific pickling processes may require the use of different types of pickling corrosion inhibitors. Before using acid pickling corrosion inhibitors, it is recommended to carefully read the product instructions and safety operation guidelines, and use them according to the correct usage methods to ensure safe and effective cleaning effects. In addition, relevant safety regulations should be strictly followed and personal protective measures should be taken during use.
