Ceramic membrane support body based on perlite aggregate and preparation method of ceramic membrane support body
The invention discloses a perlite aggregate-based ceramic membrane support body and a preparation method thereof. The perlite aggregate-based ceramic membrane support body comprises a connecting layer and a liquid passing layer connected with the connecting layer, the connecting layer and the liquid passing layer both comprise perlite; the liquid passing layer comprises a first liquid passing layer and a second liquid passing layer; the porosity of the connecting layer is 52-60%, and the internal aperture of the connecting layer is 3-22 [mu] m; the high bonding strength of the ceramic membrane support and a subsequently attached membrane layer is achieved, few impurities are left in the support in the using process, and the ceramic membrane support is high in porosity and high in strength.
本发明公开了一种基于珍珠岩骨料的陶瓷膜支撑体及其制备方所述基于珍珠岩骨料的陶瓷膜支撑体包括连接层以及与连接层连接的通液层；所述连接层、通液层均包括珍珠岩；所述通液层包括第一通液层、第二通液层；所述连接层孔隙率为52‑60％，连接层内部孔径为3‑22μm；实现陶瓷膜支撑体与后续附着的膜层结合强度高，且使用过程中支撑体内部残留杂质少，陶瓷膜支撑体孔隙率高且强度较高。
