Preparation method of ceramic plate, ceramic plate and ceramic filter plate
The invention discloses a preparation method of a ceramic plate. The preparation method is characterized by comprising the following steps: 1, firing a substrate on which macropores are uniformly distributed; 2, carrying out at least two times of spraying and at least two times of firing on the substrate to prepare a multi-layer microporous surface film; 3, firing after each time of spraying, andthen continuously spraying, wherein the pore diameters of the microporous surface films sprayed each time are different, and the pore diameters are continuously reduced; and 4, changing the aperturesof all the layers of the multi-layer microporous surface film in gradient. According to the preparation method of the ceramic plate and the prepared ceramic plate, the water content of fine-particle-size iron ore concentrate dehydration can be effectively reduced, the attenuation period of the ceramic plate can be effectively shortened, and the filtering efficiency is guaranteed.
本发明公开了一种陶瓷板的制备方法，其特征在于，包括以下步骤：步骤一：烧制基板，基板上均匀分布有大孔；步骤二：在基板上进行至少两次喷涂，以及至少两次烧制，制备多层微孔表面膜；步骤三：每次喷涂后进行烧制，再继续喷涂；每次喷涂的微孔表面膜的孔径不同，孔径不断缩小；步骤四：多层微孔表面膜的各层的孔径之间呈梯度变化。本发明陶瓷板的制备方法，以及制备的陶瓷板，能有效降低细粒径铁精矿脱水的水分，并能有效降低陶瓷板的衰减周期，保证过滤效率。
