氯化钠对硅铝酸钠溶液粘度性质的影响

Effect of NaCl on Viscosity of Sodium Aluminosilicate Solution

考察不同质量浓度的氯化钠对硅铝酸钠溶液粘度的影响.结果表明:当温度升高时,硅铝酸钠溶液的粘度变小.当氯化钠的质量浓度在30 g/L以下时,随着氯化钠质量浓度的增加溶液的粘度变大.当氯化钠的质量浓度为60 g/L时,硅铝酸钠溶液的粘度迅速降低.通过红外谱图分析可知,这是由于氯化钠的加入改变了硅铝酸钠溶液的内部结构所致.

This experiment mainly studied about the influence of sodium chloride to the viscosity of sodium aluminosilicate solution. The result of this experiment indicated： the viscosity of the solution reduces gradually along with the augment of temperature. When the content of sodium chloride is under 30 g/L, viscosity of the solution increases with adding sodium chloride to the solution. But when the content of sodium chloride of the solution is 60 g/L, viscosity of the solution reduces rapidly even less than the solution whose content of sodium chloride is under 60 g/q-.. Through the analysis of infrared spectra of the solution, we can know this change result from adding sodium chloride, which change the inner structure of the sodium aluminosilicate solution.
