Product Details
Introduction
Hydroxyphosphono-acetic Acid (HPAA) has good chemical stability, is not easy to hydrolyze, is not easily destroyed by acid and alkali, is safe and reliable to use, non-toxic and pollution-free, HPAA can increase the solubility of zinc, has a strong corrosion inhibition effect, and the corrosion inhibition performance of HPAA is higher than that of HEDP and EDTMP. HPAA is mainly used as a cathode corrosion inhibitor for metals, and is widely used in corrosion and scale inhibition of circulating cooling water systems in the steel, petrochemical, electric power, and pharmaceutical industries. It is suitable for use as a corrosion inhibitor for low-hardness, easily corrosive water.
