| Popis: | Novel low molecular weight copolymers (termed as YMR-series polymers) prepared through reaction of maleic anhydride with n-alkylacrylamide monomers via nitroxide-mediated radical polymerization (NMRP), atom transfer radical polymerization (ATRP) and free radical polymerization have shown feasibility as a new generation scale inhibitor. The scale inhibition property of these YMR-polymers towards CaCO3 in the artificial cooling water was studied in steel (316 L) and copper (90/10, CuNi alloy) pipes using a pipe flow system at various temperatures. The relationship between deposited scale mass and temperature was deduced from experimental data. The effect on formation of CaCO3 scales was investigated with scanning electronic microscopy (SEM) and X-ray powder diffraction (XRD) analysis. The results showed that the low molecular weight YMR-polymers were excellent calcium carbonate scale inhibitor in copper and steel pipe flow system showing inhibition up to 98% at 60 °C. |
