hóa chất Hydroxyphosphono Acetic Acid HPAA
2-Hydroxyphosphonocarboxylic Acid (HPAA) CAS No 23783-26-8Molecular Formula: C2H5O6P Molecular weight: 156Properties: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.Specification:itemsindexAppearanceDark umber transparent viscous liquidSolid content %Phosphorous acid（as PO33-）% Density （20℃）g/cm3pH（1％ solution）47.0-50.04.0max1.30min 1.0-3.0Usage:HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better.Package and Storage:Normally In 250kg net Plastic Drum, IBC drum can also be used as required.
