Thermal degreasing rate control method for gel-casting ceramic green body
The invention relates to a thermal degreasing rate control method for a gel-casting ceramic green body. The method comprises the following steps of: performing non-isothermal thermal weight loss analysis on the gel-casting ceramic green body, obtaining pyrolysis kinetic parameters of a polymer by adopting a thermal analysis kinetic method, and then constructing a staged temperature rise control algorithm in a thermal degreasing process of the ceramic green body, so that accurate prediction and controllability of the thermal degreasing rate of the ceramic green body are realized. The method is suitable for the complex situation that a gel polymer in a ceramic green body has multiple pyrolysis peaks, the whole thermal degreasing process is subjected to staged heat preservation and further optimization, the calculation period is shorter than one minute, and the application range is wide.
一种凝胶注模陶瓷生坯热脱脂速率控制方法，通过对凝胶注模陶瓷生坯进行非等温热失重分析，并采用热分析动力学方法获得聚合物的热解动力学参数，而后构建陶瓷生坯热脱脂过程分阶段升温控制算法，以实现对陶瓷生坯热脱脂速率的精准预测及可控。本发明适用于陶瓷生坯中的凝胶聚合物存在多个热解峰的复杂情况，对整个热脱脂过程进行分阶段保温并进一步优化，计算周期小于一分钟，适用范围广。
