| titleOfInvention | Method for separating cutting fluid, silicon carbide and silicon powder from wafer cutting mortar |
| abstract | The invention discloses a method for separating cutting fluid, silicon carbide and silicon powder from wafer cutting mortar. The method comprises the steps that: solid-liquid separation is carried out; solid obtained by separation is washed by using ethanol, and is then washed by using pure water; the solid is dried by centrifugation; Particle size composition and distribution state of silicon powder and silicon carbide/metal composition are determined by using a laser particle size analyzer; a mass ratio of the components is precisely determined by X-ray diffraction; the obtained data are converted into horizontal spiral sedimentation centrifuge sorting parameters; with the horizontal spiral sedimentation centrifuge, sand powder is primarily separated into coarse powder with main components of silicon carbide and iron, middle powder with main components of silicon carbide and silicon, and fined powder with a main component of silicon; the middle powder is added into an electrophoresis tank; the electrode in the electrophoresis tank is powered; under the action of an electric field, the silicon carbide powder is precipitated, and the silicon powder floats; the obtained silicon carbide powder and the coarse powder is subjected to alkali washing and iron-removing magnetic separation; and the obtained material is washed by using water, and is dried by centrifugation. The method provided by the invention is innovative than an ultrafine particle separation technology in waste mortar processing in prior arts. With the method, an existing pollution problem can be comprehensively treated and solved. |
