Preparation method and application of multi-channel cordierite plate ceramic membrane support
The invention discloses a preparation method and an application of a multi-channel cordierite plate ceramic membrane support. The preparation method includes the following steps: 1) weighing solid raw material components according to the following weight percentage ratio, and mixing the components, ball-milling the mixture, adding RO water, heating the mixture to 40-85 DEG C and ball-milling the mixture to obtain slurry; 2) maintaining the temperature of the slurry to be 40-85 DEG C, vacuum-defoaming the slurry, injecting the slurry into a plate-frame moulding die, and performing in-situ moulding at 0-40 DEG C to obtain a wet blank; 3) demoulding the wet blank, shade-drying the wet blank at room temperature, drying the wet blank at 40-100 DEG C, and sintering the blank in air at 1000-1400 DEG C with temperature maintained to obtain the multi-channel cordierite plate ceramic membrane support. The preparation method is carried out through the gel-casting process so that the method is wide in available range and is free of special demand on powders, and is low in cost, is easy to control in processes and achieves near-net-shape moulding to produce parts having complex shapes. The blank is high in strength, allows mechanical processing, is low in organic substance content, allows direct sintering and is free of individual gum removal. The blank and the sintered body have good performance uniformity.
