Preparation method of porous ceramic matrix, atomizing core and aerosol forming device
The invention provides a preparation method of a porous ceramic matrix, an atomizing core and an aerosol forming device.The preparation method of the porous ceramic matrix comprises the steps that zinc oxide, aluminum hydroxide, a filling agent and a pore forming agent are provided and mixed to obtain a mixed powder material, an organic solvent and deionized water are provided, the mixed powder material, the organic solvent and water are mixed to obtain mixed slurry, and the mixed slurry is prepared into the porous ceramic matrix. The mixed slurry is subjected to tape casting to obtain a ceramic green body, and the ceramic green body is subjected to glue discharging and sintering to form the porous ceramic matrix with the zinc-aluminum spinel structure. The porous ceramic matrix prepared by the water-based tape casting method is relatively small in internal stress, the porous ceramic matrix is flat in surface, uniform in pore size distribution and relatively good in use effect after the tape casting ceramic green body is sintered, and zinc oxide and aluminum hydroxide form a regular octahedron crystal form zinc-aluminum spinel structure in the sintering process. The strength and the service life of the porous ceramic matrix can be improved.
本申请提供了一种多孔陶瓷基体的制备方法、雾化芯及气溶胶形成装置，多孔陶瓷基体的制备方法包括提供氧化锌、氢氧化铝、填充剂、及造孔剂，混合得到混合粉体料，提供有机溶剂和去离子水，将混合粉体料、有机溶剂和水混合得到混合浆料，将混合浆料流延成型得到陶瓷生坯，将陶瓷生坯进行排胶、烧结形成具有锌铝尖晶石结构的多孔陶瓷基体。水基流延成型的方法制备的多孔陶瓷基体内应力较小，流延成型的陶瓷生坯烧结后多孔陶瓷基体表面平整，孔径分布均匀，使用效果较好，氧化锌和氢氧化铝在烧结过程中形成具有正八面体晶型的锌铝尖晶石结构，可以提高多孔陶瓷基体的强度及使用寿命。
