Performance and Applications
HPAA has good chemical stability, is not easy to hydrolyze, and is not damaged by acid and alkali. The product is safe, reliable, non-toxic and pollution-free, can improve the solubility of zinc, has extremely strong corrosion inhibition effect, and its corrosion inhibition performance is higher than that of HEDP and EDTMP.
HPAA is mainly used as a cathodic corrosion inhibitor for metals; it is widely used in scale and corrosion inhibition of circulating cooling water systems in steel, petrochemical, electric power, pharmaceutical and other industries, and is suitable as a corrosion inhibitor for low hardness and corrosive water quality in southern China.
