膨润土是一种重要的粘土矿资源,它具有许多独特的性能,如吸水膨胀性、润滑性、粘结性和吸附性等,可以用作增塑剂、粘结剂、脱色剂和吸附剂等,使用范围不断扩大,利用价值日增。天然膨润土中主要成分是蒙脱石,它是一种含水的层伏铝硅酸盐矿物,化学式是(1/2 Ca,Na)_(0.7)(Al,Mg,Fe)_4(Si,Al)_8O_(20)(OH)_4·nH_2O。膨润土的化学特性主要与其中蒙脱石的化学组成、晶体构造及组会形式等有关。由于天然膨润土还达不到工业应用所要求的程度,因此要对膨润土进
Bentonite is an important clay mineral resource, it has many unique properties, such as water swelling, lubricity, adhesion and adsorption, etc., can be used as plasticizers, binders, bleaching agents and adsorbents , The use of expanding, increasing the value of use. The main component of natural bentonite is montmorillonite, which is an aqueous layer of voltosilicate minerals with the formula (1/2 Ca, Na) _ (0.7) (Al, Mg, Fe) _4 (Si, Al ) _8O_ (20) (OH) _4 · nH_2O. The chemical properties of bentonite are mainly related to the montmorillonite’s chemical composition, crystal structure and form of assembly. Because natural bentonite can not reach the level required by industrial applications, so to bentonite into
