| Abstract: | Using swill-cooked dirty oil as modifier,surface depolarization modification for Xiangtan sepiolite ore powder was carried out under normal temperature and water-phase,and hydrophobic sepiolite powder was prepared.The phase composition,microstructure and surface properties were characterized by X-ray powder diffraction(XRD),scanning electron microscopy(SEM),Fourier infrared(FTIR),chemical titration and surface potential measurements.hydrophobic sepiolite powder was prepared.The modification mechanism of swill-cooked dirty oil for sepiolite were explored. |
