The invention relates to a corrosion and scale inhibitor, which comprises a component A and a component B, wherein the component A comprises an organic phosphine compound, a multipolymer dispersant and deionized water; the component B comprises polyphosphate, inorganic zinc salt and molybdate, wherein the mass ratio of the component A to component B is 2:1-1:2. The corrosion and scale inhibitor also comprises a component C, wherein the component C comprises an azole compound, a hydroxide, an organic solvent and deionized water. Compared with a traditional single liquid corrosion and scale inhibitor, the corrosion and scale inhibitor of the invention has strong composite formula adaptability, ratio and dilution times can be timely adjusted according to client on-site water quality; for the terminal clients, storage space is saved, transport cost is reduced, and usage cost of its agent is reduced simultaneously. |
