摘要
通过加入一种添加剂CaCl2,显著改善了凹凸棒石黏土的吸湿性能,并对添加剂加入后凹凸棒石黏土的吸湿机理进行了一定的探讨。实验表明,当CaCl2加入量达15%时,其在不同湿度下的吸湿量均高于常用干燥剂硅胶,且添加剂无毒、无污染,价格便宜,可作为生产凹凸棒石黏土干燥剂的添加剂使用。
The hygroscopicity of attapulgite clay can be improved remarkably throught adding an additive CaCl2 and The hygroscopicity theoretics of attapulgite clay including additive is discussed in the paper. This research indicates that The hygroscopicity of attapulgite clay is higher than silica gel when the dosage of CaCl2 is 15%. The additive is nontoxic, non-pollution and cheap, so it can be used for production of attapulgite clay desiccant.
