1. Used as corrosion inhibitor.?HPAA has excellent corrosion inhibition performance, especially in low hardness, low alkalinity, and strong corrosive water, it shows extremely strong corrosion inhibition effect.?HPAA has a good chelation with divalent ions. It can be used as a metal ion stabilizer to effectively stabilize Fe2+, Fe3+, Mn2+, Al3+ plasma in water to reduce corrosion and scaling; HPAA can significantly reduce the deposition of calcium carbonate and silica. Good scale inhibition performance, but HPAA has slightly worse scale inhibition performance for calcium sulfate scale.?In order to avoid the decomposition of HPAA by the oxidizing bactericide, a protective agent can be used, but it is less affected by residual chlorine (0.5-1.0 mg/L) in the cooling water system of intermittent chlorination.?The combined use of HPAA and zinc salt has obvious synergistic corrosion inhibition effect.?The recommended concentration is generally 5 ~ 30mg/L.?Dosing equipment should be resistant to acid corrosion.?2.HPAA is mainly used as a metal cathode corrosion inhibitor. It is widely used in the corrosion and scale inhibition of circulating cooling water systems in steel, petrochemical, power, medicine and other industries. It is suitable for use as a corrosion inhibitor for low hardness, easily corrodible water quality in southern China. HPAA The compounding effect with zinc salt is better.?Organic corrosion and scale inhibitors composed of low molecular weight polymers have excellent performance.
