The Effect of Compound Corrosion Inhibitor of Sodium Silicate in the Chlorine Dioxide Solution

Article Preview

Abstract:

The corrosion inhibition effect of composite inhibitors of sodium silicate on carbon steel was studied in 200 mg/L chlorine dioxide solution by static weight-loss method at room temperature (25 °C) .Analyzed the possible corrosion mechanism and the optimal conditions. The results show that sodium silicate and HEDP had apparent synergistic effect in chlorine dioxide solution. When the mass concentration of sodium silicate was 200 mg/L and HEDP was 100 mg/L can make the corrosion inhibiting rate on carbon steel up to 86.58%.
