摘　　要：常规改性膨润土作造纸微粒助留剂使用时,在低pH值下既不方便,效率也不高,并且生产粉末状膨润土成本高。因此,造纸中使用高浓液相膨润土有很大的应用潜力。文中综述了各种制备高浓液相膨润土的方法。Conventional modified bentonite,which is activated by sodiu m carbonate and supplied as dry powder,is neither convenient nor efficient at l ow pH value as a microparticle retention aid in papermaking.Also,the productio n of dry powder bentonite is not cost effective.But the modified bentonite in the form of concentrated fluid dispersion shows its application potential in pa permaking.In this paper,various methods of preparing concentrated fluid benton ite dispersion are reviewed.
