properties | HPAA has good chemical stability, is not easy to hydrolyze, is not easy to be damaged by acid and alkali, safe and reliable, non-toxic and pollution-free, it can improve the solubility of zinc and has a strong corrosion inhibition effect. Its corrosion inhibition performance is 5 to 8 times higher than that of HEDP and EDTMP. The organic corrosion and Scale Inhibitor composed of low molecular weight polymer has excellent performance. |
Application | 2-hydroxyphosphonoacetic acid is mainly used as a cathode corrosion inhibitor for metals, which is widely used in steel, petrochemical, electric power, the corrosion and scale inhibition of circulating cooling water system in medicine and other industries is suitable for use as a corrosion inhibitor for low hardness and easily corrosive water quality in Southern China, and the effect of zinc salt is better. It is widely used for scale inhibition and corrosion inhibition of circulating cooling water systems in iron and steel, petrochemical, electric power, pharmaceutical and other industries, and is suitable for low hardness water quality in Southern China. HPAA can be widely used in steel, petrochemical, electric power, the scale inhibition and corrosion inhibition of circulating cooling water system in medicine and other industries are generally compounded with zinc salt to form corrosion inhibitor, which is suitable for low hardness water quality in Southern China and has scale inhibition effect. |
