Slurry formula and production process of gel casting ceramic filter
The invention discloses a slurry formula and a production process of a gel-casting ceramic filter, and the production process comprises the following steps: step 1, mixing ceramic powder, a chemical crosslinking system, a physical crosslinking system and water, fully ball-milling, and adding an initiator into the mixture to prepare a ceramic slurry; step 2, carrying out vacuum defoaming on the ceramic slurry, then injecting the ceramic slurry into a mold, heating to form a physical and chemical cross-linked network, and carrying out gelation to obtain a ceramic blank; 3, demolding the ceramic blank, and drying to form a ceramic filter blank; 4, immersing the ceramic filter blank into the catalyst solution, and depositing a catalyst layer on the surface of the blank; step 5, carrying out ceramic glue discharging and sintering; and 6, carrying out surface metallization on the ceramic by using the catalyst deposited on the surface of the ceramic and adopting a chemical plating process to obtain a ceramic filter product. And a large-size or complex-structure product can be easily formed through a corresponding mold design and a pouring process.
本发明公开了一种凝胶注模陶瓷滤波器的浆料配方及生产工艺，步骤1、将陶瓷粉体、化学交联体系、物理交联体系和水混合后充分球磨，然后向其中加入引发剂配置成陶瓷浆料；步骤2、将陶瓷浆料进行真空脱泡，然后注入到模具中加热以形成物理和化学交联网络，进行凝胶化获得陶瓷胚体；步骤3、将陶瓷胚体脱模，干燥后形成陶瓷滤波器胚体；步骤4、将陶瓷滤波器胚体浸入到催化剂溶液中，在胚体表面沉积一层催化层；步骤5、进行陶瓷排胶和烧结；步骤6、利用陶瓷表面所沉积的催化剂，采用化学镀的工艺对陶瓷进行表面金属化，得到陶瓷滤波器产品。可以通过对应的模具设计和浇注工艺能够轻易成型大尺寸或结构复杂的产品。
