HPAA 2-hydroxyphosphonyl acetic acid

Performance and Use:

HPAA has good chemical stability, is not easy to hydrolyze, is not easily damaged by acid and alkali, safe and reliable to use, non-toxic and non-polluting, HPAA can improve zinc solubility, has a very strong corrosion inhibition effect, HPAA corrosion inhibition performance is higher than HEDP, EDTMP.HPAA is mainly used as cathodic corrosion inhibitor for metals, and is widely used as corrosion and scale inhibitor for circulating cooling water system in iron and steel, petrochemical, electric power, medicine and other industries. It is suitable for use as corrosion inhibitor for low hardness, corrosion-prone water quality in southern China.

Usage method:

The organic corrosion and scale inhibitor composed of HPAA and low molecular weight polymer has excellent performance.The combination of HPAA and zinc salt has better effect

Quality indicators:
