【Abstract】 The water-soluble polymer MA-SAS-AM was prepared by solution polymerization technique with water as solvent and persulfate as initiator. Scale inhibition and dispersion performances of the polymer as well as anti-corrosion were studied, and the effects of polymer concentration, pH value, Ca 2+ concentration, and temperature were evaluated. The experimental results showed that the polymer had an excellent efficiency of scale inhibition against Ca-3(PO-4)-2 and good against zinc salt, but poor against CaCO-3. The scale inhibition efficiency against Ca-3(PO-4)-2 was 97.0%, and 69.0% against zinc salt with 12mg/L polymer at pH=9.0. Fe-2O-3 could be dispersed well by the polymer and the corrosion of steel was decreased to some extent.更多还原
