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%.

The inhibition effects of sodium silicate, phytic acid and their mixtures in 5% NaCl solutions have been investigated using weight loss method and Tafel polarization techniques. The surface morphology of carbon steel was obtained using scanning electron microscopy (SEM). The results show that the co-addition of 70 mg∙1-1sodium silicate and 5 g∙1-1phytic acid has the optimum inhibition efficiency (84.15%) and the lowest corrosion rate (0.13 g∙m-2∙h-1). Compared with their individual inhibition effects, the optimum inhibition efficiency of sodium silicate is 62.17% at 90 mg∙1-1and phytic acid is 80.05% at 15 g∙1-1, respectively. The results obtained from weight loss method and Tafel polarization curves are in good agreement. The results show the enhanced inhibition effect by the inhibitors mixtures.

Degumming of pre-chlorite treated jute fiber was studied in this paper. The effects of sodium hydroxide concentration, treatment time, temperature, sodium silicate concentration, fiber-to-liquor ratio, penetrating agent TF-107B concentration, and degumming agent TF-125A concentration were the process conditions examined. With respect to gum decomposition, fineness and mechanical properties, sodium hydroxide concentration, sodium silicate concentration, and treatment time were found to be the most important parameters. An orthogonal L9(34) experiment designed to optimize the conditions for degumming resulted in the selection of the following procedure: sodium hydroxide of 12g/L, sodium silicate of 3g/L, TF-107B of 2g/L, TF-125A of 2g/L, treatment time of 105 min, temperature of 100°C and fiber to liquor ratio of 1:20. The effect of the above degumming process on the removal of impurities was also examined and the results showed that degumming was an effective method for removing impurities, especially hemicellulose.
