Abstract

The invention discloses a processing method for an antibacterial ceramic knife. The processing method comprises the following steps that zirconium oxide powder with stable yttrium oxide, an antibacterial agent, a dispersing agent and deionized water are mixed and then prepared into slurry through ball milling, wherein the particle size of the zirconium oxide powder is 10-30 nm, and the particle size of the antibacterial agent is 10-50 nm; a binding agent is added into the slurry, the materials are stirred to be uniform, and granulating is performed to obtain zirconium oxide ceramic granulation powder; the zirconium oxide ceramic granulation powder is processed through preforming pressing and then processed through isostatic pressing treatment, and a green body is obtained; the green body is sintered to obtain a blank; the blank is polished, burnished and edged to obtain the antibacterial ceramic knife. According to the processing method for the antibacterial ceramic knife, the made ceramic knife is uniform in internal structure, higher in density and bending strength and better in tenacity, and the processed knife edge is sharp; in addition, due to the fact that the antibacterial agent is added, the antibacterial ceramic knife can have the better antibacterial property.

Description

technical field [0001] The invention relates to the technical field of zirconia ceramics, in particular to a processing method of an antibacterial ceramic knife. Background technique [0002] As a new type of high-tech ceramics, zirconia ceramics have properties such as high strength, high fracture toughness, high hardness, excellent heat insulation performance and high temperature resistance, and are widely used in the fields of structural ceramics and functional ceramics. In addition, zirconia is non-magnetic, non-conductive, non-rusting, and wear-resistant. It is also widely used in the field of biomedical equipment, props, and tools. Recently, partially stabilized zirconia (TZP) can be used to prepare magnetically shielded watch cases, corrosion-resistant watch parts and other instrument parts by powder metallurgy. In addition to the above applications, TZP is also widely used in decoration, life, medicine, piezoelectric ceramics, sensor ceramics and other fields. [0...
