Problems solved by technology

[0010] At present, zirconia ceramic ferrules produced by domestic and foreign counterparts usually use Japanese raw materials and Japanese injection molding technology to produce zirconia ceramic ferrules, but this technology has certain shortcomings, such as high raw material costs, and insufficient degreasing of ferrule blanks. The cycle is long, the production efficiency is low, and the performance of the produced ceramic ferrule is not good
The Chinese invention patent application specification with the application number 201310083180.X discloses "a zirconia ceramic ferrule and its preparation method". The zirconia powder and organic carrier are mixed in a weight ratio of 100:10-30 and then passed through dense Refining, injection molding, oil soaking, thermal degreasing, and sintering processes. The pressure used in the injection molding step is low pressure. During low pressure injection, due to the low pressure, the density of the injection material is not high, and pores are easy to form, and The injection material cannot completely fill the mold, which will not only reduce the qualified rate of the ceramic ferrule, but also affect the hardness and compactness of the finished ferrule, and also reduce the production efficiency; there are two degreasing processes in the patent application scheme, namely foaming Oil and heat degreasing can remove the lipids in the ferrule blank, but if the ferrule blank is soaked in kerosene first, and then heated and sintered, the surface of the ferrule blank will gradually turn black, which will affect the performance of the final product. In addition, Some components in kerosene will diffuse into the ferrule blank after heating, affecting the effect of degreasing

Abstract

The invention discloses a zirconia ceramic ferrule. With zirconia ceramic powder as a main material, an ethylene-vinyl acetate copolymer, an oleic acid, polymethacrylate, atactic polypropylene and paraffin are added in the mixing process, and thus the prepared zirconia ceramic ferrule is good in abrasive resistance, strong in ageing resistance, strong in environmental adaptability, and high in strength. The invention also discloses a production process of the zirconia ceramic ferrule. The process comprises the following steps: sequentially drying, mixing, preforming, crushing, injection molding, thermal debinding, sintering, grinding and the like. High-pressure low-speed injection is adopted in the injection molding process; the compactness and absence of an air hole are ensured; the preparation method is simple, easy to control, low in cost, and high in production efficiency; the pass rate of the produced product is high; and the production process is suitable for production of the zirconia ceramic ferrule.
