摘要
采用水热碱溶法对硅藻土制备硅酸钠的工艺进行了探索性研究。就碱浸时间、碱用量、液固比三个因素做了正交试验,得出最佳因子组合。结果表明,碱用量和液固比对碱浸影响显著,碱浸时间在75min以上则对碱浸影响不明显。
Technique elements of alkali leaching time, dosage of alkali and liquid-solid ratio of preparing sodium silicate by diatomite were studied by orthogonal testing, it was got the optimal factor group. The results showed that the effects of dosage of alkali and liquid-solid ratio on the alkali leaching axe highly conspicuous. When time is more than 75minits influence on the alkali leaching is small.
