5.Usage:HPAA is mainly used as metal cathode corrosion inhibitor. It can be widely used in the
circulating cool water system, play as a corrosion inhibitor in the field of steel & iron,
petrochemcal, power plant and medicine. It is suitable as a corrosion inhibitor for the low-hardness
and corrosion water of the south of China. When built with zinc salt, the effect is even better.
