摘要:

研究了微硅粉湿法制备水玻璃的热力学及溶出工艺,考察了反应时间、反应温度、硅碱配比、液固比对SiO浸出率和水玻璃模数的影响。结果表明,利用微硅粉湿法制备水玻璃是可行的。其最佳工艺条件为:反应温度180℃、原料硅碱配比为2.5、液固比10mL/g、反应时间40min,在此工艺条件下,SiO浸出率为77.1%,水玻璃模数为2.3。

Abstract:

|Thermodynamics and the conditions of sodium silicate prepared by  micro-silica fume were study. The effects of reaction time,reaction temperature,the ratio of silicon base and the liquid-solid ratio on the leaching rate of SiO2 and modulus were investigated. The results demonstrated that sodium silicate prepared by  micro-silica fume is feasible.  The optimum preparation condition was obtained from the dissolution experiment: reaction temperature of 180 0C,the ratio of silicon base of 2. 5, the solid ratio of 10 mL/g and reaction time of 40 min.  The dissolution rate of Si02 and sodium silicon modulus were 77. 1% and  2. 3 respectively  under the optimum condition.

Key words: micro一silica fume, sodium silicate, dissolution rate, modulus
