Scale and corrosion inhibitor is a chemical substance that prevents or reduces the formation of scale layers and alleviates corrosion by altering the behavior of soluble salts in water and the properties of metal surfaces.
Scale inhibition principle:
Coordination effect: Chemical substances in scale and corrosion inhibitors can react with dissolved salt ions in water. By forming stable complexes with metal ions, scale inhibitors can reduce the tendency of metal ions to deposit and crystallize, thereby reducing the formation of scale layers.
Ion exchange: Some scale and corrosion inhibitors contain ion exchange resins or polymers that can adsorb and exchange the position of salt ions in water. By adsorbing and removing salt ions, scale inhibitors can reduce the degree of salt deposition and crystallization, thereby preventing the formation of scale layers.
Corrosion inhibition principle:
Corrosion inhibitor adsorption: The chemical substances in the corrosion inhibitor can adsorb on the metal surface, forming a protective film. This thin film can reduce the electrochemical activity of the metal surface and slow down the corrosion rate of the metal.
Corrosion inhibitor reaction: Some chemicals in corrosion inhibitors can react chemically with oxygen, water, or other active substances on the metal surface. These reactions can form a barrier product on the metal surface, thereby reducing corrosion and oxidation of the metal.
It should be noted that the principles and mechanisms of specific scale and corrosion inhibitors may vary depending on the product type and application field. When using, the recommendations and usage methods in the product manual should be followed to ensure safety and optimal scale and corrosion inhibition effects.
