In order to improve the dispersibility, thermal stability and ph adaptability of organic pigments in water, submicrometer copper phthalocyanine (cupc)/sio 2 composite particles (cps) were prepared through a simple one-pot wet ball-milling process under acidic conditions without using any organic surfactant. in the as-obtained cps, the surface of the cupc particles was homogeneously decorated.
Regardless of the grinding wheel, though, all grinding processes use abrasive particles to “grind” away material from a workpiece’s surface. when a workpiece is exposed to a grinding wheel, some of its material will rub off. with that said, grinding is often used to both remove material from workpieces as well as polish.
Jan 18, 2012 the fabrication of copper–graphite composites by a milling process was investigated using a centrifugal ball mill. the copper particles were homogeneously milled in a graphite vessel, and the reaction time was varied. scanning electron microscopy images clearly revealed that a fragment of graphite ground by the copper particle adheres to the.
