Properties of the Copolymer of Sodium p-Styrene Sulfonate and Maleic Acid (SSS/MA)

The SSS/MA is the best scale inhibitor and dispersant among all the polymers for cooling water treatment. The copolymer contains carboxylic acid groups and sulfonic acid groups, the scale inhibition rate of calcium carbonate, phosphate root, calcium sulfate is more than 90% and has excellent ability to disperse iron oxide, the stability rate of zinc ion is more than 90%.The polymer has excellent temperature resistance, which is better than hydrolyzed polymaleic anhydride and solvent polymaleic anhydride, and is a good substitute for solvent polymaleic anhydride.

Used in flash unit for seawater desalination and low pressure boiler and industrial circulating cooling water, especially for Texaco gas furnace ash water scale control.

The addition of SSS/MA to the boiler water effectively prevents the accumulation of scale and sludge and it disperses, or conditions, accumulated sludge enabling it to be removed by blow down.

It prevents deposits from forming on the water side surfaces, maintains efficient heat transfer, and decreases the incidence of boiler clean up, thus lowering operating costs.
