Properties:
Through the introduction of phosphonic group
into carboxylic group,
POCA has good dispersion property for scale of calcium carbonate
and calcium phosphate in circulating cool water system. It has
good scale inhibition for barium sulfate, strontium sulfate
and silica scale. POCA has
advantages in wide range of water quality, chemical stability,
strong chlorine tolerance, etc.POCA can be used as scale and corrosion inhibitor in circulating
cool water system and oilfield refill water system.
