Scale and corrosion inhibitor is a chemical substance used to prevent or reduce scale and corrosion on metal surfaces. They work through different mechanisms, and the main functions of scale and corrosion inhibitors are as follows:
Scale inhibition effect: Scale and corrosion inhibitors can react or physically interact with dissolved substances in water to prevent or reduce the formation of scale deposits. They can change the crystallization mode of scale deposits or inhibit their crystallization process, making them less prone to deposition and accumulation on metal surfaces.
Corrosion inhibition effect: Scale and corrosion inhibitors can provide protection for metal surfaces and reduce corrosion reactions between metals and the environment. They can form a protective corrosion inhibitor film on the surface of the metal, reducing the possibility of contact between the metal and oxygen, water molecules, or other corrosive media, thereby slowing down or inhibiting the corrosion rate of the metal.
Cleaning effect: Some scale and corrosion inhibitors also have the ability to clean metal surfaces, removing existing scale deposits or oxide layers, and restoring the smoothness and activity of metal surfaces. The cleaning effect helps to better exert the protective effect of scale and corrosion inhibitors and maintain the good condition of metal surfaces.
Overall, scale and corrosion inhibitors are widely used in fields such as water treatment, industrial production, boilers, and cooling systems. They can protect metal surfaces from the effects of scale and corrosion, extend the service life of equipment, improve process efficiency, and reduce the cost of equipment maintenance and replacement. However, selecting appropriate scale and corrosion inhibitors and the correct usage method are crucial to ensure their effectiveness and avoid adverse effects.
