It can chelate with Fe, Cu, and Zn ions, and dissolve the oxidized materials. This salt has good scale and corrosion inhibition effects even under 250℃. </div> <div> HEDP Na<sub>2</sub> is stable under high pH value, not easy to be hydrolyzed, not easy to be decomposed under normal light and heat condition. Its acid/alkaline and chloride oxidation tolerance are better than that of other organophosph-onic acids. </div> <div> HEDP Na<sub>2 </sub>can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. It has good scale inhibition effects and obvious dissolution threshold effects. When used with other Water Treatment Chemicals, the synergistic effect is better. </div> <div align="left"> <b>Specification:</b> </div> <div align="center"> <table border="1" cellspacing="0" cellpadding="0" width="500"> <tbody> <tr> <td width="197"> <div align="center"> Items </div> </td> <td colspan="2"> <div align="center"> Index </div> </td> </tr> <tr> <td width="197"> <div align="left"> Appearance </div> </td> <td width="140"> <div align="center"> Colorless to yellowish transparent liquid </div> </td> <td width="143"> <div align="center"> White powder </div> </td> </tr> <tr> <td width="197"> <div align="left"> Active content (HEDP) % </div> </td> <td width="140"> <div align="center"> 16.5 min </div> </td> <td width="143"> <div align="center"> 74.0-79.0 </div> </td> </tr> <tr> <td width="197"> <div align="left"> Active content (HEDP Na<sub>2</sub>) % </div> </td> <td width="140"> <div align="center"> 20.0 min </div> </td> <td width="143"> <div align="center"> 89.8 min </div> </td> </tr> <tr> <td width="197"> <div align="left"> density (20℃) g/cm<sup>3</sup> </div> </td> <td width="140"> <div align="center"> 1.12-1.22 </div> </td> <td width="143"> <div align="center"> -- </div> </td> </tr> <tr> <td width="197"> <div align="left"> Fe, mg/L </div> </td> <td width="140"> <div align="center"> -- </div> </td> <td width="143"> <div align="center"> 35 max </div> </td> </tr> <tr> <td width="197"> <div align="left"> Phosphorous acid (as PO<sub>3</sub><sup>3-</sup>) % </div> </td> <td width="140"> <div align="center"> -- </div> </td> <td width="143"> <div align="center"> 3 max </div> </td> </tr> <tr> <td width="197"> <div align="left"> Moisture % </div> </td> <td width="140"> <div align="center"> -- </div> </td> <td width="143"> <div align="center"> 3.0-6.0 </div> </td> </tr> <tr> <td width="197"> <div align="left"> pH (1% water solution) </div> </td> <td width="140"> <div align="center"> 4.0-6.0 </div> </td> <td width="143"> <div align="center"> 4.0-6.0 </div> </td> </tr> </tbody> </table> </div>
