Hydroxy Phosphonoacetic Acid (HPAA)
Properties:
Hydroxy phosphonoacetic acid (HPAA) is chemically stable. It is hard to be hydrolyzed and to be destroyed by acid or alkali. So HPAA water treatment chemical is safe to use. It also has no toxicity and no pollution.
Hydroxy phosphonoacetic acid 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.
