| Abstract: | Effect of temperature, pressure, pH, shearing rate, metal ion and time on the rheological property of the Polyacrylate acid sodium(PAS) were studied in this paper. The results showed that for PAS of 0.5～2.5g/L concentrtion, the temperature and concentration exhibited great influence while acid and alkali could lower the viscosity of PAS. The influence of acid is much larger and the maximum viscosity was observed at pH 9. The metal ion of the salt solution could lower the viscosity of PAS. This solution showed the characteristic of shearing-thin fluid. |
