The experimental results showed that the surfactants can enhance the penetration ability and decrease the surface tension of the calcium chloride and water glass solutions in great extent. After adding the surfactants in 0.2—0.6 wt.% to the solutions of calcium chloride and water glass in 5—25 wt.% respectively, the largest percent of penetration ability increases to 28% more. Among the three surfactants, the size of their effects on the penetration ability of calcium chloride and water solutions in the dust samples is dodecyl benzene sulfonic acid sodium salt, sodium dodecyl sulfonate and sodium succinate.The achieved conclusions are great significant for calcium chloride and water glass to be applied in the field of soil stabilization and raising dust control.展开更多

The process of direct volatilization or reduction oxidation volatilization was employed to produce the mixture of As 2O 3 and Sb 2O 3, and then Na 2SO 4 was added to produce clarificant for glass. The optimizing technology conditions which were obtained from the test of preparing the mixture of pure As 2O 3 and Sb 2O 3 by the volatilization method are reaction temperature 900 ℃ and reaction time about 30 min. The glass clarificant produced meets industrial application standard.展开更多
