制取活性白土,通常是用膨润土、凹凸棒石和海泡石作为原料。日前浙江省发现一种含高岭石52.12％、伊利石(含蒙脱石)16.58％、石英17％、长石14％、有机质10.27％的粘土,活性度只有95,比表面积只有90.21m~2/g,约比膨润土低1倍多,但脱色力却非常大,原土为125,活化土达到222,而且活化特别容易,酸耗量很低,不足2％,实为非金属矿物原料的新发现,生产活性白土的极好原料。它可 Preparation of activated clay, usually bentonite, attapulgite and sepiolite as raw materials. Zhejiang Province recently discovered a clay containing 52.12% kaolinite, illite (including montmorillonite) 16.58%, quartz 17%, feldspar 14%, organic matter 10.27% clay, the activity of only 95, the specific surface area of ​​only 90.21m ~ 2 / g, about 1 times lower than the bentonite, but the decolorization power is very large, the original soil is 125, activated earth reached 222, and activation is particularly easy, low acid consumption, less than 2%, in fact, non-metallic mineral raw materials The new discovery, the production of activated clay is an excellent raw material. It can be
