A corrosion inhibitor is a chemical whose main function is to slow down or prolong the corrosion rate of metallic materials. Corrosion is a chemical reaction that occurs when metals interact with substances such as oxygen, water, and acids in the surrounding environment. Corrosion inhibitors slow down the corrosion of metal surfaces by chemically reacting with these corrosive media or forming a protective film layer.

Corrosion inhibitors can be divided into two categories according to their mechanism of action: anodic and cathodic. Anodic corrosion inhibitors slow down the corrosion process by donating electrons to the metal surface, forming a protective oxide film. Cathodic corrosion inhibitors reduce the probability of corrosive media contacting the metal surface by forming a protective film covering the metal surface.

The use of corrosion inhibitors can have the following benefits:

Extend the service life of metal materials: Corrosion inhibitors can reduce the corrosion rate of metals, prolong the life of metal materials, and reduce the frequency of maintenance and replacement.

Protect the integrity of equipment and structures: Corrosion can cause damage to metal surfaces and loosening of corrosion products. The use of corrosion inhibitors can protect the integrity of equipment and structures and reduce possible safety risks.

Reduced maintenance costs: By extending the life of equipment and metal structures, corrosion inhibitors can reduce the cost required for maintenance and repairs.

Environmental friendliness: The use of corrosion inhibitors can reduce the corrosion rate of metals, thereby reducing environmental pollution and waste of resources.

It should be noted that when using corrosion inhibitors, it should be operated strictly in accordance with the instructions of the instructions and comply with relevant safety regulations to ensure safe and effective corrosion control.
