用稻壳、稻草制取水玻璃过程中金属杂质的去除及其机理分析

Analyses of Removing and Mechanisms of Metal Imputies Producing Sodium Silicate from Rice Husk and Straws

对用稻壳、稻草制备水玻璃所剩余的炭渣进行了分析，给出实验结果．结果表明：金属成分在水玻璃的制备过程中以难溶化合物的形式被除去；难溶化合物能与酸反应，转化为可溶化合物；新技术制取的水玻璃溶液与传统方法相比，纯度相同，甚至更高．

The nature of carbon sludge remained during the producing of water glass from rice husk or rice straw is studied.The results show:during the producing of water glass,the new technology can get rid of metal impurties which have been formed undissolved compounds;the undissolved compound can dissolved in acid;the purity of water glass producing by new technology is as same as or higher than the purity of it wthich is produced by the tradional technology sometimes.
