1 Features This product is stable even at high temperature and high pH value. Low toxicity and harmless, it forms stable complex with many metal ions such as iron, calcium and magnesium ions. At the same time, it has the function of corrosion inhibitor. This product is better resistant to chlorine and oxidation than other inorganic or organic (phosphonic) acid salt. Good compatibility with other water treatment chemicals. It has good solubility for BTA copper corrosion inhibitor. It is an excellent scale and corrosion inhibitor.
2 Applications
Widely used in circulating cooling water system in power plants, chemical industry, metallurgy and other industrial as scale and corrosion inhibitor for water boiler, heat exchangers, water pipes, oilfield water injection pipe, and crude pipeline.
