实践证明,钠质膨润土的技术性能比钙质膨润上的技术性能好得多。我国不少的省区都蕴藏和已开采大量的膨润土,但天然钠质膨润上的产量却很少。为了满足对钠质膨润土日益增多的要求,我们以黑山钙质膨润土(下称钙质上)做母本,用湿法改性,成功地研制了改性钠质膨润土(下称钠质土)。经过几年的生产和厂家现场使用,证明了改性钠质土的技术性能在国内处于领先地位。取得了经济效益。一、膨润土改性机理膨润土的性能是由蒙脱石的性能决定的。从蒙脱石单位晶胞上分析,蒙脱石属于2:1
Practice has proved that the technical performance of sodium bentonite calcification than calcium on the technical performance is much better. Many provinces and autonomous regions in our country have large amounts of bentonite stored and mined, but the production of natural sodium swell is small. In order to meet the increasing demand for sodium bentonite, we Montenegro calcium bentonite (hereinafter referred to as calcium) as the mother of the wet modification, successfully developed a modified sodium bentonite (hereinafter referred to as sodium) . After several years of production and on-site use of the manufacturer, it proves that the technical performance of the modified sodium-bearing soil is in a leading position in China. Achieved economic benefits. First, the bentonite modification mechanism Bentonite performance is determined by the performance of montmorillonite. From montmorillonite unit cell analysis, montmorillonite belongs to 2: 1
