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