Preparation method of disc type multichannel ceramic membrane
The invention discloses a preparation method of a disc-type multi-channel ceramic membrane, which comprises the following steps: firstly, filling a mold cavity with a proper amount of granulation pug and paving, then carrying out injection molding on a plurality of plastic rubber blocks with the same shape as a channel, uniformly placing the plastic rubber blocks on the flattened powder surface, then filling a proper amount of granulation pug and paving, and finally, carrying out injection molding on the plastic rubber blocks to obtain the disc-type multi-channel ceramic membrane. And carrying out compression molding by using a molding press, demolding and sintering to obtain the support body with the channel inside. A mold with a flow guide groove is not needed, the forming difficulty is greatly reduced, the mold cost is reduced, the biscuit is integrally formed through a forming press, the filling plastic rubber block is decomposed and discharged in the high-temperature sintering process, an internal channel of the supporting body is formed, the attaching process of two biscuits is omitted, and the production efficiency is improved. And the integrity and the strength reliability of the support body are ensured.
本发明公开了一种圆盘式多通道陶瓷膜的制备方法，先在模具腔内装入适量的造粒泥料并铺平，然后注塑多个跟通道形状一样的塑料胶块，在铺平后的粉面上均匀放置各个塑料胶块，往里再装入适量的造粒泥料并铺平，采用压型机压制成型，脱模、烧结得内有通道的支撑体。本发明无需采用有导流槽的模具，大大降低了成型难度，降低了模具成本，且采用压型机一体成型素坯，并借助填充塑料胶块在高温烧结过程中分解排去，形成支撑体的内部通道，省去了两片素坯的贴合工艺，保证了支撑体的完整性和强度可靠性。
