Through the introduction of phosphonic group
into carboxylic group,
PCA 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.PCA has advantages in wide range of water
quality, chemical stability, strong chlorine tolerance, etc.
PCA can be used as scale and
corrosion inhibitor in circulating cool water system and
oilfield refill water system.
