摘　　要：以海泡石黏土为原料,采用高压均质-水热活化的工艺进行处理,得到超细活性粉体材料;采用扫描电镜、比表面积、粒度分析、zeta电位、FT-IR等对处理前后的海泡石进行表征,并探讨了结构及性能调控机理。结果表明:处理后的海泡石材料粒度(D90)降低到0.47μm,比表面积、孔径增大,表面负电性增强,材料的吸附性能提高。The sepiolite was processed by high pressure homogenization-hydrothermal treatment to obtain a hyperfine active material,the sepiolite and processed sepiolite were characterized by SEM,BET,grain size analyser,zeta potential and FTIR,the mechanism of structure and property change was analyzed.The results showed that the size(D90)of the processed sepiolite was 0.47μm,the surface area and pore diameter magnified,the electronegativity increased,the adsorptive property of the material was enhanced.
