| titleOfInvention | Composite scale and corrosion inhibitor and application thereof in medium and hard water |
| abstract | The invention relates to the field of circulating cooling water treatment, and discloses a composite scale and corrosion inhibitor which comprises a condensation reaction product of gluconate and triethanolamine, 2-phosphonobutane-1, 2, 4-tricarboxylic acid, a sulfonic acid group-containing copolymer and zinc salt, wherein the weight ratio of the condensation reaction product of gluconate and triethanolamine to the 2-phosphonobutane-1, 2, 4-tricarboxylic acid to the sulfonic acid group-containing copolymer to the zinc salt is 1 (0.8-1.5) to (1.3-5) to (0.17-0.8), and the weight of the zinc salt is calculated by zinc ions; wherein the gluconate is sodium gluconate and/or potassium gluconate. The composite scale and corrosion inhibitor provided by the invention has a synergistic effect among the components, has good corrosion and scale inhibition effects, is few in component and low in dosage, and is particularly suitable for medium-hardness circulating cooling water treatment in which the sum of the hardness of water supplementing calcium and the total alkalinity is C, and C satisfies that 100mg/L < C <300 mg/L. |
