High-specific-surface-area ceramic powder, preparation method and high-liquid-retention-capacity ceramic diaphragm
The invention belongs to the technical field of diaphragms, and particularly relates to high-specific-surface-area ceramic powder, a preparation method and a high-liquid-retention-capacity ceramic diaphragm. The preparation method of the high-specific-surface-area ceramic powder comprises the following steps of: pulping ceramic particles and water, carrying out primary grinding and primary sieving, adding a grinding dispersant, carrying out secondary grinding, carrying out secondary sieving and dehydration on the ceramic slurry subjected to secondary grinding, performing drying, carrying out airflow crushing, crushing agglomerated particles, and removing impurities, and conducting third sieving to obtain ceramic powder; putting the ceramic powder into a sintering furnace for sintering, and then carrying out ultrasonic crushing and fourth sieving to obtain the high-specific-surface-area ceramic powder; the high-specific-surface-area ceramic powder can be prepared through grinding for several times, sintering and secondary granulation; the high-specific-surface-area ceramic powder is coated on the surface of an isolating membrane to prepare the high-liquid-retention-capacity diaphragm, so that the liquid retention capacity of the diaphragm is improved.
本发明属于隔膜技术领域，具体涉及一种高比表面积陶瓷粉末及制备方法、高保液量陶瓷隔膜；所述高比表面积陶瓷粉末的制备方法，包括以下步骤：将陶瓷颗粒与水打浆后，进行一次研磨、一次过筛后，加入研磨分散剂，进行二次研磨，将二次研磨后的陶瓷浆料进行二次过筛、脱水后，烘干干燥、经气流粉碎、破碎团聚颗粒、去除杂质后，进行三次过筛得到陶瓷粉末；将陶瓷粉末放入烧结炉内烧结后，经超声粉碎、四次过筛后得到高比表面积陶瓷粉末；本发明通过对陶瓷粉末进行分次研磨后，烧结二次造粒后，制得一种高比表面积陶瓷粉末；将该高比表面积陶瓷粉末涂敷于隔离膜的表面，制得一种高保液量隔膜，以提高隔膜的保液量。
