摘要
利用采集到的国内主要产地的膨润土原矿,分析了各地膨润土的理化性能,探讨了膨润土的理化性能与层间阳离子的关系。研究结果表明,膨润土因其属型和属性不同使其理化性能有较大的差异,其中层间阳离子类型是影响膨润土理化性能的重要因素,钠基膨润土具有高的胶质价、膨胀指数等理化指标优于其他类型的膨润土。
Chemical compositions and physicochemical properties of bentonite raw ores are analyzed and investigated systematically,which were collected from main internal production places.The relationship between physicochemical properties and interlayer cations of bentonite is also discussed.The result shows that,the physicochemical properties of bentonite are distinct different with different attributes and genotypes.Interlayer cation type plays an important role in determining the physicochemical properties of bentonite.Colloid index,expansion index and other physicochemical indexes of sodium bentonite are all better than those of the other type bentonites.
