Polyether polyamino methylene using phosphonates method for high pH scale control |
摘要 |
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.
