Embodiment 1
[0017] A co-precipitation method is used to prepare zirconia nanometer powder with a particle size of 20-50nm. The zirconia nanopowder, the mixed solution of dispersant ethanol and deionized water are put into a sand mill for grinding treatment, and the hard agglomeration is eliminated by mechanical crushing. Wherein ethanol accounts for 15% of the total volume of the mixture. The sand mill uses zirconia beads with a diameter of 0.3-3mm as the grinding media, and the grinding duration is 24 hours. Add the binder polyvinyl alcohol (PVA) to the ground product, put it into a sand mill and grind it for 2 hours, and then filter the zirconia beads with a mesh of 0.2mm to obtain a slurry; among them, the polyvinyl alcohol is added The amount is 1% of the mass of the ground product. The slurry is transported to a spray drying tower for spray granulation treatment to obtain an average diameter distribution of 40-70um.

[0021] A co-precipitation method is used to prepare zirconia nanometer powder with a particle size of 20-50nm. The zirconia nanopowder, the mixed solution of dispersant ethanol and deionized water are put into a sand mill for grinding treatment, and the hard agglomeration is eliminated by mechanical crushing. Wherein ethanol accounts for 10% of the total volume of the mixture. The sand mill uses zirconia beads with a diameter of 0.3-3mm as the grinding media, and the grinding duration is 12 hours. Add the binder polyvinyl alcohol (PVA) to the ground product, put it into a sand mill and grind it for 4 hours, and then filter the zirconia beads with a mesh of 0.2mm to obtain a slurry; among them, the polyvinyl alcohol is added The amount is 2% of the mass of the ground product. The slurry is sent to a spray drying tower for spray granulation treatment to obtain an average diameter distribution of 40-80um.

[0025] A co-precipitation method is used to prepare zirconia nanometer powder with a particle size of 20-50nm. The zirconia nanopowder, the mixed solution of dispersant ethanol and deionized water are put into a sand mill for grinding treatment, and the hard agglomeration is eliminated by mechanical crushing. Wherein ethanol accounts for 12% of the total volume of the mixture. The sand mill uses zirconia beads with a diameter of 0.3-3mm as the grinding media, and the grinding duration is 20 hours. Add the adhesive polyvinyl alcohol (PVA) to the ground product, put it in a sand mill for 3 hours and filter the zirconia beads with a mesh of 0.2mm to obtain a slurry; among them, the polyvinyl alcohol is added The amount is 0.5% of the mass of the ground product. The slurry is transported to a spray drying tower for spray granulation treatment to obtain an average diameter distribution of 50-80um.
