摘要
The feasibility for preparation of ultrafine bentonite powder by different milling methods was studied. And the comparison of comprehensive performance between ultrafine bentonite grease and traditional bentonite grease was also investigated. The results indicated that the statistic Z-average size of ultrafine bentonite prepared by sand milling was 250 nm with a narrow size distribution and the lattice structure of ultrafine bentonite maintained good character despite a slight distortion occasioned. The mechanical stability, colloid stability, antiwear ability and friction-reducing property of ultrafine bentonite grease were superior to the traditional one.
