Polyether polyamino methylene phosphonates for high pH scale control. |
| 摘要 |
<p>Polyether polyamino methylene phosphonates possess high calcium tolerance and have been found to give excellent inhibition of the formation, deposition and adherence of scale-forming salts, especially calcium carbonate, under severe conditions which include elevated pH, high dissolved solids content, and high saturation levels of calcium carbonate.</p> |
