Ceramic tube shell green body preparation method and prepared ceramic tube shell green body
The invention discloses a ceramic tube shell green body preparation method and a prepared ceramic tube shell green body, and relates to the field of ceramic tube shell processing, and the ceramic tube shell green body preparation method comprises the following steps: S1, sequentially stacking green ceramic chips to form a green ceramic chip lamination group, and arranging a release film at the bottom of the green ceramic chip lamination group to form a green ceramic assembly; a cavity needing to be formed is located within the coverage range of the release film; s2, stacking more than one green ceramic assembly on one green ceramic sheet lamination group, and laminating to form a multi-layer green ceramic assembly; and S3, etching layer by layer from top to bottom in a laser etching mode, stripping the green body above the release film layer every time one layer of green ceramic combination body is etched, namely, cavity opening is completed, the bottommost layer of green ceramic sheet lamination group does not participate in etching, and after all cavities are formed, a ceramic tube shell green body is formed. The ceramic tube shell prepared by the method is extremely small in cavity deformation quantity, high in air tightness and good in reliability; the side wall of the cavity is smooth, and the appearance qualification rate is high; the process is simplified and the production efficiency is high.
本发明公开了提供一种陶瓷管壳生坯制备方法及其制备的陶瓷管壳生坯，涉及陶瓷管壳加工领域，包括：S1将生瓷片依次堆叠形成生瓷片叠层组，并在其底部设置离型膜形成生瓷组合体；所需开设腔体位于离型膜的覆盖范围以内；S2将1个以上生瓷组合体堆叠在1组生瓷片叠层组上，进行叠压，形成多层生瓷组合体；S3采用激光刻蚀的方式，从上往下逐层刻蚀，每刻蚀一层生瓷组合体，剥离该层离型膜上方的生坯，即完成腔体开设，最底层生瓷片叠层组不参与刻蚀，所有腔体开设完后，即形成陶瓷管壳生坯。本发明制备的陶瓷管壳的腔体形变量极小、气密性高、可靠性好；腔体侧壁光滑，外观合格率高；工艺简化，生产效率高。
