a.Inorganic Corrosion Inhibitors: Include silicates and polyphosphates. They form a protective film on the metal surface in water to isolate the metal from the corrosive medium and prevent corrosion.b.Organic Corrosion Inhibitors: Such as benzotriazole, mercaptobenzothiazole, and tolyltriazole. They can adsorb on the metal surface through chemical bonds to form a dense protective film, effectively preventing the corrosion of metal materials by water and dissolved substances in water.
