water treatment chemical / corrosion inhibitor--PCA / Phosphino Carboxylic Acid

1. water treatment PCA 40% 2. Copolymer of Phosphono and carboxylic Acid 3. used as oilfield refill water system

Copolymer of Phosphono and carboxylic Acid / PCA

1.Properties and Usage:

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.
