摘要
以湖北鄂州某地钙基膨润土为原料,采用双螺旋挤压钠化改型工艺,以Na2CO3为改型剂制备钠基膨润土,确定了该地区膨润土钠化改型最优生产工艺条件。实践表明,钠化改型后的膨润土性能有较大的提高,可满足冶金球团用膨润土的要求。
Using Ca-bentonite produced from Ezhou Hubei province as raw materials and adopting the double-helix extrusion modification mechanism, the Na-based bentonite modified with Na2CO3 has been prepared, the optimum conditions of this Na-activated bentonite prodution technology are comfirmed, which can greatly improve the Na-activated bentonite properties for spheric agglomeration application.
