Ceramic 3D printing product and degreasing and roasting integrated process method thereof
The invention relates to the technical field of 3D printing, in particular to a ceramic 3D printing product and a degreasing and roasting integrated technological method thereof. The degreasing and roasting integrated technological method for the ceramic 3D printing product comprises degreasing and roasting of a ceramic blank, wherein the degreasing comprises the steps: placing the ceramic blank in a reaction device, increasing the temperature to 200 DEG C from the room temperature and performing heat preservation; raising the temperature from 200 DEG C to 500 DEG C and keeping the temperature; finally, increasing the temperature to 800 DEG C from 500 DEG C, and performing heat preservation; the roasting comprises the steps: after degreasing reaches 800 DEG C and heat preservation is finished, increasing the temperature to 1000 DEG C from 800 DEG C after the reaction device is filled with air, and performing heat preservation; raising the temperature from 1000 DEG C to 1280 DEG C and keeping the temperature. According to the process method provided by the invention, the ceramic degreasing green body can keep certain strength, most organic matters in the ceramic green body can be rapidly removed in a defect-free manner, the specific setting of slow and complex heating rate and heat preservation time according to the thermal degreasing characteristic of an organic adhesive in theair thermal degreasing process is avoided, and the universality is good.
本发明涉及3D打印技术领域，特别涉及一种陶瓷3D打印产品及其脱脂焙烧一体化工艺方法，其中，所述陶瓷3D打印产品脱脂焙烧一体化工艺方法，包括对陶瓷胚体的脱脂和焙烧，所述脱脂包括将陶瓷胚体置于反应装置内，先由室温升至200℃并保温；再由200℃升至500℃并保温；最后由500℃升至800℃并保温；所述焙烧包括在脱脂达到800℃并保温结束之后，向反应装置内充入空气后由800℃升至1000℃并保温；再由1000℃升至1280℃并保温。本发明提供的工艺方法，可使陶瓷脱脂坯体保持一定的强度，快速、无缺陷的脱出陶瓷坯体中的大部分有机物，避免空气热脱脂过程中需要根据有机黏结剂的热脱脂特性进行缓慢、复杂的升温速率和保温时间的特定设置，普适性好。
