Flat ceramic membrane support and preparation method thereof
The invention discloses a preparation method of a plate ceramic membrane support body. The plate ceramic membrane support body comprises the following raw materials in parts by weight: 100 parts of spheroidic alumina powder; 3-7 parts by weight of a starch pore-forming agent; 1-3 parts by weight of an aqueous binder; 0.2-5 parts by weight of a nonmetallic mineral or alkali metal oxide sintering aid; 0.0004 to 0.0008 part by weight of a water-soluble auxiliary agent; 10-25 parts by weight of water. The invention also discloses the plate ceramic membrane support body prepared by the method. According to the method disclosed by the invention, the formula components of the flat ceramic membrane support body are optimized, and the generation of harmful waste gas is greatly reduced by adopting an oil-free auxiliary agent. And the prepared flat ceramic membrane support body has the advantages of concentrated pore size distribution, good chemical stability, high mechanical strength, convenience in cleaning and the like, can be well used for treating complex water bodies such as dye wastewater, petrochemical wastewater and the like, and greatly widens the application range.
本发明公开一种平板陶瓷膜支撑体的制备方法，原料包括：类球形氧化铝粉100重量份；淀粉造孔剂3～7重量份；水系粘结剂1～3重量份；非金属矿物或碱金属氧化物烧结助剂0.2～5重量份；水溶性助剂0.0004～0.0008重量份；水10～25重量份。还公开该方法制备的平板陶瓷膜支撑体。本发明的方法优化了平板陶瓷膜支撑体的配方组分，采用无油助剂，大大减少了有害废气的产生。制备的平板陶瓷膜支撑体孔径分布集中，具备良好的化学稳定性，机械强度高，方便清洗等优点，能够很好地用于处理染料废水、石油化工废水等复杂水体，极大的拓宽了其应用范围。
