Glue discharging method of ceramic body and preparation method of ceramic workpiece
The invention relates to the technical field of additive manufacturing, in particular to a glue discharging method of a ceramic body and a preparation method of a ceramic workpiece. The glue discharging method comprises the following steps: 1) carrying out preheating treatment on a ceramic green body in an inert atmosphere, wherein the preheating treatment temperature is 150-250 DEG C; and (2) the ceramic body obtained in the step (1) is subjected to heat preservation heat treatment in an oxygen-containing atmosphere, the initial temperature of the heat preservation heat treatment is 100-300 DEG C, and the final temperature of the heat preservation heat treatment is 450-800 DEG C. The preparation method of the ceramic workpiece comprises the following steps: 1) carrying out glue removal on a ceramic body by adopting the glue removal method; and 2) sintering the ceramic green body after glue removal to obtain the ceramic workpiece. The decomposition rate of organic matters in the ceramic body can be effectively reduced, the cracking tendency of the ceramic body is reduced, and the glue discharging success rate is increased.
本发明涉及增材制造技术领域，尤其涉及一种陶瓷坯体的排胶方法和陶瓷工件的制备方法。该排胶方法包括如下步骤：1)将陶瓷坯体在惰性气氛下进行预热处理，预热处理的温度为150～250℃；2)将步骤1)得到的陶瓷坯体在含氧气的气氛下进行保温热处理，保温热处理的初始温度为100～300℃，最终温度为450～800℃。该陶瓷工件的制备方法包括如下步骤：1)将陶瓷坯体采用该排胶方法进行排胶；2)将排胶后的陶瓷坯体进行烧结处理，得到所述陶瓷工件。本发明能够有效降低陶瓷坯体内有机物分解速率，降低陶瓷坯体开裂倾向，提高排胶成功率。
