Hollow plate ceramic membrane and preparation method thereof
The invention relates to a preparation method of a hollow plate ceramic membrane, which comprises the following steps: preparing spherical aluminum oxide for a support body and spherical aluminum oxide for a microporous membrane; preparing slurry of the support body and the microporous membrane; preparing a support body green body, drying the support body green body, sintering the support body green body, spraying slurry to the support body, and sintering the ceramic membrane. The invention also discloses a hollow plate ceramic membrane, which comprises a support body and a microporous membrane which are integrated. The invention provides a preparation method of a hollow plate ceramic membrane, which converts general industrial wastes into industrial separation products with higher added value and improves the comprehensive utilization rate of spherical alumina production enterprises. The invention also provides a hollow plate ceramic membrane which can replace the existing organic flat-plate membrane, hollow fiber membrane or common ceramic flat-plate membrane, can be used in a harsh environment, has high mechanical strength and large flux, can be backwashed through reverse pressure application, reduces the cleaning frequency of the membrane and prolongs the service life of the membrane.
本发明公开了一种中空平板陶瓷膜的制备方法，步骤包括支撑本体用球形氧化铝和微孔膜用球形氧化铝制备、支撑本体和微孔膜浆料制备、支撑本体坯体制备、支撑本体坯体干燥、支撑本体坯体烧结、支撑本体喷浆、陶瓷膜烧成。本发明还公开了一种中空平板陶瓷膜，包括一体化的支撑本体和微孔膜。本发明提供一种中空平板陶瓷膜的制备方法，将一般工业废弃物转化为附加值较高的工业分离产品，提高球形氧化铝生产企业的综合利用率。本发明还提供了一种中空平板陶瓷膜，可替代目前的有机平板膜、中空纤维膜或普通陶瓷平板膜，可以在苛刻的环境中使用，另一方面其机械强度较高，通量大且可以通过反向施压进行反冲洗，减少膜的清洗次数，提高膜的使用寿命。
