Novel flat ceramic microfiltration membrane
The invention discloses a novel flat plate ceramic microfiltration membrane, and relates to the technical field of membrane separation, the novel flat plate ceramic microfiltration membrane comprises a micropore functional layer located in the middle and gradient symmetric porous layers located on two sides, the porosity of the gradient symmetric porous layers is gradually increased from the inner side to the outer side, the pore diameter of the micropore functional layer is 0.08-12 [mu] m, the thickness is 45-55 [mu] m, and the pore diameter of the gradient symmetric porous layers is 10-20 [mu] m. The aperture of the gradient symmetric porous layer is greater than 9 microns, and the thickness of the gradient symmetric porous layer is 450-1200 microns. The microporous functional layer is located in the middle and plays a role in screening, the gradient porous layers on the two sides play a role in supporting, the mechanical strength of the microfiltration membrane is enhanced, the service life of the membrane is greatly prolonged, and the gradient porous layers on the two sides play a role in protecting the functional layer, so that the microfiltration membrane can keep stable performance for a long time in severe environments such as strong acid, strong alkali and the like.
本发明公开了一种新型平板陶瓷微滤膜，涉及膜分离技术械领域，其包括位于中间的微孔功能层以及位于两侧的梯度对称多孔层，所述梯度对称多孔层的孔隙率由内侧向外侧呈现出递增趋势，所述微孔功能层的孔径为0.08–12μm，厚度为45‑55μm，所述梯度对称多孔层的孔径均大于9μm，厚度为450‑1200μm。本发明中微孔功能层位于中间起筛分作用，两侧梯度多孔层起支撑作用，增强了微滤膜的机械强度，大大提高了膜的使用寿命，两侧梯度多孔层对功能层起保护作用，使得微滤膜在强酸强碱等恶劣环境下长期可以保持性能稳定。
