Atomizing core, porous ceramic and preparation method of porous ceramic
The invention discloses an atomizing core, porous ceramic and a preparation method of the porous ceramic. The preparation method of the porous ceramic comprises the steps of mixing at least two types of diatomaceous earth with different particle sizes to form a raw material; mixing the raw material, a sintering aid, a reinforcing agent and a pore forming agent to form a mixture; mixing at least two binders to form a wax block; mixing the mixture with the wax block to form a ceramic material; preparing a green body from the ceramic material through an injection molding process; and degreasing and sintering the green body to form the porous ceramic. The wax block and the mixture are prepared in advance, so that the powder can be mixed more uniformly, and the pore diameter of the prepared porous ceramic is uniform; the diatomite is subjected to particle size matching, and gaps can be filled with diatomite particles with a smaller particle size, so that the porous ceramic has higher porosity, and a better pore diameter ratio is obtained; and the green body is prepared in an injection molding manner, so that the preparation process is simple and convenient, the technological process is simple, and mass production is easy.
本发明公开了一种雾化芯、多孔陶瓷及多孔陶瓷的制备方法。多孔陶瓷的制备方法包括：将至少两种不同粒径的硅藻土混合形成原料；将原料、助烧剂、增强剂和造孔剂混合形成混合料；将至少两种粘结剂混合形成蜡块；将混合料和蜡块混合形成陶瓷料；利用陶瓷料通过注射成型工艺制备坯体；以及对坯体进行脱脂与烧结处理以形成多孔陶瓷。通过提前制备蜡块和混合料，可以使粉料之间混合更均匀，进而使得制备得到的多孔陶瓷的孔径均匀；通过对硅藻土进行粒度搭配，可以利用较小粒径的硅藻土颗粒对间隙进行填充，使得多孔陶瓷具有较高的孔隙率，得到更好的孔径配比；并且通过采用注塑成型的方式制备坯体，可以使得制备过程简单便捷，工艺流程简单，易量产。
