HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better. </p> <h2> <span style="font-size:16px;">Specification</span> </h2> <div> <table style="width:470px;height:160px;" class="aliDataTable" border="1" cellspacing="0" cellpadding="2" align="center"> <tbody> <tr> <td> items </td> <td> index </td> </tr> <tr> <td> <span style="color:#000000;">Appearance</span> </td> <td> Dark umber transparent viscous liquid </td> </tr> <tr> <td> <span style="color:#000000;">Solid content %</span> </td> <td> 47.0-50.0 </td> </tr> <tr> <td> <span style="color:#000000;">Phosphorous acid(as PO₃<span style="font-family:Arial;">^3-</span>)%</span> </td> <td> 4.0 max </td> </tr> <tr> <td> <span style="color:#000000;">Density (20°C)g/cm^{<span style="font-family:Arial;">3</span>}</span> </td> <td> 1.30 min </td> </tr> <tr> <td> <span style="color:#000000;">pH(1% solution)</span> </td> <td> 1.0-3.0 </td> </tr> </tbody> </table> <h2> <span style="font-size:16px;">Usage</span> </h2> <p> HPAA is mainly used as cathode corrosion inhibitin oilfield refill water system in fields such as steel & iron, petrochemcal, power plant medical industries.
