The invention discloses a preparation process for filament-attached porous ceramic based on an organic foam impregnation method, belonging to the field of porous ceramic. According to the preparationprocess, multi-point wall-attached filaments are added into an acid-base solution, and the surface of an uneven foam skeleton is filled with the multi-point wall-attached filaments along with the corrosion of the acid-base solution to organic foam; after slurry hanging, the multi-point wall-attached filaments are clamped between ceramic slurry and the foam skeleton; in the process of sintering, the multi-point wall-attached filaments are locally decomposed to enable a ceramic blank to form an uneven porous inner wall, and a residual filament-attached skeleton stays on the porous inner wall, sothe area of the porous inner wall of the porous ceramic is increased, and the residual filament-attached skeleton greatly improve the roughness of the inner walls of pores of the porous ceramic and enhances the adsorption performance of the porous ceramic; in the back washing desorption process of the porous ceramic, the porous inner wall of the porous ceramic can be cleaned through the residualfilament-attached skeleton, so the desorption efficiency and effect of the porous ceramic are greatly improved.
本发明公开了一种基于有机泡沫浸渍法的附丝型多孔陶瓷制备工艺，属于多孔陶瓷领域，本发明通过在酸碱溶液添加多点贴壁附丝，随着酸碱溶液对有机泡沫的腐蚀，多点贴壁附丝填充在凹凸不平的泡沫骨架表面，经过挂浆后，多点贴壁附丝夹杂在陶瓷料浆和泡沫骨架之间，在烧结过程中，多点贴壁附丝局部分解，使陶瓷坯体形成凹凸不平的孔隙内壁，残留的附丝骨架停留在孔隙内壁上，这样不仅增大了多孔陶瓷孔隙内壁面积，同时通过残留的附丝骨架大大提高了其孔隙内壁粗糙度，增强了多孔陶瓷的吸附性能，并且，在对多孔陶瓷进行反冲洗脱附过程中，通过残留的附丝骨架还可以对多孔陶瓷的孔隙内壁进行清理，大大提高多孔陶瓷的脱附效率和效果。
