The main function of corrosion and scale inhibitors is to have both corrosion and scale inhibiting effects in water treatment. The following are the functions of corrosion and scale inhibitors:
Corrosion inhibition effect: Corrosion and scale inhibitors can slow down the corrosion rate of metal surfaces. They form a protective corrosion inhibitor film on the surface of the metal, reducing the contact between the metal and dissolved oxygen, ions, and other corrosion factors in water, thereby reducing or delaying the corrosion reaction of the metal. Corrosion inhibition can protect the metal surfaces of equipment and pipelines, extending their service life.
Scale inhibition effect: Scale inhibitors can interfere with the crystallization and deposition process of minerals in water, preventing the formation and deposition of scale. They can form complexes or soluble complexes with hard water ions such as calcium, magnesium, and iron in water, inhibiting the crystallization and precipitation of these ions and preventing the formation of scale. The scale inhibition effect can reduce the blockage and damage of scale on the inner walls of equipment and pipelines, and maintain the smooth and efficient operation of the water system
Cleaning and maintenance function: Corrosion and scale inhibitors can maintain the cleanliness and good condition of the water system. They can prevent the accumulation of scale, rust, and other sediment, reducing the frequency of cleaning and maintenance of pipelines and equipment. At the same time, corrosion and scale inhibitors can also remove minor scale layers or rust that have already formed, restoring the normal operation of equipment and pipelines.
System protection: Corrosion and scale inhibitors play a role in protecting various parts of the water system in water treatment. They can protect the metal surfaces of equipment such as boilers, cooling water circulation systems, cooling towers, heat exchangers, and prevent corrosion and scale accumulation from damaging the equipment. At the same time, they can also protect the normal operation of water system components such as pipelines, valves, and pumps.
It is necessary to select suitable corrosion and scale inhibitors based on specific water quality characteristics, system conditions, and needs, and add the correct dosage according to the usage guidelines to ensure the best corrosion and scale inhibition effect.
