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 following steps: mixing ceramic aggregate, a sintering aid, glass powder and a pore forming agent to form a mixture; mixing the mixture with a binder to form a ceramic material; preparing a green body from the ceramic material through an injection molding process; and placing the green body in a degreasing disc, and placing the degreasing disc in a degreasing sintering furnace for powder-free degreasing sintering to obtain the porous ceramic. The green body is degreased and sintered by adopting a powder-free degreasing process, so a powder cleaning link after degreasing is completed can be omitted, product breakage caused in the cleaning link is avoided, no degreasing medium particles are adhered, and the risks of powder adhesion and product breakage are fundamentally solved.
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：将陶瓷骨料、助烧剂、玻璃粉和造孔剂混合形成混合料；将混合料与粘结剂混合形成陶瓷料；利用陶瓷料通过注射成型工艺制备坯体；将坯体放置于脱脂盘中，并将脱脂盘放置于脱脂烧结炉中进行无粉脱脂烧结，得到多孔陶瓷。通过采用无粉脱脂工艺对坯体进行脱脂烧结，可以省去脱脂完成后的清粉环节，避免了在清理环节造成的产品破碎，同时也无任何脱脂介质颗粒粘附，从根本上解决了粘粉以及产品破碎的风险。
