Category:Polycarboxylate scale inhibitor dispersant
- Product Description
-
Aliases: POCA, PCA
CAS No.: 71050-62-9Performance and Applications
POCA introduces phosphonic acid groups into the original carboxylic acid groups, has good dispersion performance on calcium carbonate and calcium phosphate scale in circulating cooling water, and also has a good inhibitory effect on the deposition of barium sulfate, strontium sulfate and silica scale. It has a synergistic effect when compounded with other organophosphonates and copolymers. The product has the characteristics of wide applicable water quality range, good chemical stability and strong chlorine oxidation resistance. It is mainly used for scale inhibition and corrosion inhibition of industrial circulating cooling water systems and oilfield reinjection water systems.
