Preparation method of nanoscale zirconium oxide grinding medium
The invention relates to a preparation method of a nanoscale zirconium oxide grinding medium. The preparation method comprises the following steps of selecting 3Y-ZrO2 composite powder as a raw material; feeding the 3Y-ZrO2 composite powder into a grinder to be ground to slurry with the grain size of 90 nm and then discharging the slurry outward; adjusting the solid content of the slurry to 65-75%, and adjusting the viscosity of the slurry; generating static electricity by means of a high voltage electrostatic generator, connecting an anode and a cathode of the high voltage electrostatic generator to a metal titration disc and a metal reaction kettle, separately, feeding the slurry into the metal titration disc, and filling the metal reaction kettle with a reaction solution, wherein the slurry has positive charges and the reaction solution has negative charges; dripping the slurry from the metal titration disc to the reaction kettle to react to form by means of attraction of positive charges and negative charges to form titrated microbeads; drying and sintering the titrated microbeads to form spherical kernels; carrying out sand-grinding treatment on 500-600-mesh spherical kernels;carrying out wet process rolling on the spherical kernels after sand-grinding treatment to form 0.1 mm microbeads; and carrying out ball billet air-drying, drying, glue discharging, sintering, polishing and screening to obtain product nano ground zirconium beads. The zirconium oxide beads prepared by the preparation method have the characteristics of being compact and uniform in inner structure,good in resistance and high in grinding efficiency.
