| titleOfInvention | Ecological water treatment chemical with corrosion and scale inhibition performance |
| abstract | The invention discloses an ecological water treatment chemical with corrosion and scale inhibition performances, which comprises the following components: beta-dicarbonyl compound modified polyaspartic acid as main agent, sodium molybdate, hydroxy ethylidene diphosphonic acid and zinc salt as auxiliary agent. The ecological water treatment chemical can be applied to a circulating cooling water treatment system, has excellent corrosion and scale inhibition performance, has the inhibition rate of 100 percent on calcium carbonate, has the annual corrosion rate of less than 0.075mm on A3 carbon steel, and discharges Zn in water 2+ The concentration is 0-1.5 mg/L, the content of phosphorus in the discharged water is 0-0.05 mg/L, no harm is caused to the environment due to the high content of phosphorus and zinc, and increasingly strict environmental protection requirements are met. |
