Scale and corrosion inhibitors refer to substances and chemicals used on the surface of metals and their alloys to provide protection.

Trace amounts of scale and corrosion inhibitors can significantly reduce the corrosion rate of the protected material in the medium, prevent surface scaling, and maintain good heat transfer performance of the equipment.

Scale and corrosion inhibitors are mainly used in industrial circulating water systems such as power plants, steel plants, fertilizer plants, oilfield water injection systems, and so on.

The commonly used scale inhibitors in water treatment include inorganic polyphosphates, organic phosphonic acids, phosphonic carboxylic acids, organic phosphonic acid esters, polycarboxylic acids, etc.
