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