What are the corrosion inhibitors

Corrosion inhibitors have various types and chemical components, and common corrosion inhibitors include:

Organic corrosion inhibitors: such as organic amines, acids, ketones, etc. They form a protective film by reacting with the metal surface, playing a corrosion inhibiting role.

Nitrates: such as sodium nitrite, ammonium nitrite, etc. They are a commonly used type of corrosion inhibitor, widely used in water treatment and rust prevention.

Phosphate: such as phosphite, polyphosphate, etc. They can form complexes or precipitates with metals, forming a protective film on the metal surface and slowing down the corrosion rate.

Corrosion inhibiting polymers: such as corrosion inhibiting resins, polymer modifiers, etc. This type of corrosion inhibitor can form a dense polymer coating on the metal surface, playing a role in blocking and inhibiting corrosion.

Rare earth salts: such as rare earth chlorides, rare earth sulfates, etc. They can react with the metal surface to form a dense oxide or hydroxide layer, playing a corrosion inhibiting role.

Corrosion inhibitor additives: such as corrosion inhibitor lubricating oil additives, cooling water treatment agents, etc. These additives contain specific chemical components that can form a protective film on the metal surface or alter the electrochemical characteristics of the metal surface, slowing down corrosion.

Choosing a suitable corrosion inhibitor requires consideration of the specific application environment and metal materials, as well as the required corrosion control effect. When using, the product instructions should be followed, and appropriate dosage and control should be carried out according to the actual situation.
