摘要
永和海泡石粘土的微观结构呈纤维网状，孔隙率较高，具有较大的比表面积，赋予它较强的吸附能力。试验表明，该粘土的活化酸度较低，可采用工艺比较简单的冷浸法进行活化，其活化土对菜油的的脱色力在１６０～２２０之间。其原土也具有很好的脱色能力，是一种天然的优质漂白土。
The micro-view of sepiolite clay, produced in Yonghe, Liuyang, Hunan is existed as a fibrous-mesh-texture. It has higher porosity factor surface area, thus the clay has stronger absorbent capability. Experiment shows the clays activation acidity is lower and it can be activated by a simple cold-dousing method. Its decolorization strength is 166～220. Its original clay has also good decolorization capability and thus it is a good crude bleaching clay.
