中文名称：: 2-羟基膦酰基乙酸

英文名称：: 2-Hydroxy phosphono acetic Acid (HPAA)

CAS号：: 23783-26-8

HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP and EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better.
