Corrosion inhibitors are a class of chemicals that can effectively slow down the rate of corrosion of metals and play a key role in many fields.

From the point of view of the principle of action, corrosion inhibitor molecules will be adsorbed on the surface of the metal, the formation of a layer of dense protective film, this layer of film as if the metal put on the “protective clothing”, the metal and corrosive media such as acids, alkalis, salt solutions and humid air and so on isolate, thus inhibiting the occurrence of electrochemical corrosion of metal, chemical corrosion and other types of corrosion reactions, to Reduce the rate of metal loss, extend the service life of metal products.

In the industrial field, corrosion inhibitors are widely used. In oil extraction, downhole equipment at high temperatures for a long time, high pressure and full of corrosive media in harsh environments, corrosion inhibitors added to the oil pipeline and equipment, can greatly reduce metal corrosion, to ensure the continuity of mining operations, reduce equipment maintenance and replacement costs. Chemical production process involves a large number of strong acid, alkali and other corrosive chemicals, reaction kettles, pipelines and other equipment using corrosion inhibitors to protect, can stabilize the production process, to avoid corrosion leakage caused by safety accidents.

In the transportation industry, automobiles, ships, engine cooling systems, fuel systems are prone to corrosion, corrosion inhibitors into the coolant, fuel, can protect the radiator, cylinders, fuel pumps and other components, to maintain the normal operation of the equipment, reduce the chance of failure.

In the field of construction, once the steel reinforcement in the reinforced concrete structure is corroded, it will seriously affect the strength and stability of the building. Adding corrosion inhibitor concrete, can form a protective film on the surface of the steel reinforcement, resist the environment of chloride ions, carbon dioxide and other erosion of the steel reinforcement, to protect the long-term safety and stability of the building.

In daily life, household metal water pipes, heating pipes, faucets, etc., if the water contains a small amount of corrosion inhibitor, can also effectively prevent rust, extend the service life, to provide convenience for people's lives.

In short, corrosion inhibitors with its unique anti-corrosion effect, penetrate into industrial production, transportation, construction and many other areas of home, for the protection of metal materials, to ensure that the normal operation of production and life have made great achievements. It and the previously mentioned DTPMPA and other water treatment agents, although the focus of different functions, but are centered on the protection of equipment, optimize the operation of the system, and jointly help the development of various industries.
