Manufacturing method of composite oxide ceramic chopper
The invention provides a manufacturing method of a composite oxide ceramic chopper. The method includes the steps of dissolving organic monomers, cross-linking agents and dispersing agents in distilled water to prepare premixed liquid, adding aluminum oxide ceramic powder, adding zirconium oxide balls to conduct ball milling, adding initiating agents and defoaming agents, conducting uniform ball milling to obtain sizing agents, pouring the sizing agents in a mold, covering the mold with a mold cover, standing still at the room temperature, polymerizing the organic monomers in the sizing agents to achieve the gelatinization process, taking the mixture out of the mold, and conducting drying and sintering in a vacuum oven, wherein steel needles with the diameter of 0.02 mm to 0.08 mm are arranged on the lower portion of the mold cover. The composite oxide ceramic chopper is manufactured through the gel casting process, the in-situ curing process of high-concentration suspensoid sol and the slip casting process of ceramic bodies are effectively combined, ceramic chopper green bodies which are high in density and strength and quite uniform in component and structure can be manufactured within a short time, the manufacturing method has the advantages of being simple in process, economical in cost, few in green body forming defect and the like, and the composite oxide ceramic chopper can be more easily produced in an industrialized mode.
