中文摘要:
      本文以喷涂过渡层的氧化铝板为膜板支撑体,在其上采用动态喷涂法制备分离膜层。通过SEM,孔径分析等手段对所得样品进行表征。探究不同烧成温度,喷涂增重,膜浆固含对陶瓷膜孔径,形貌,膜厚的影响,得出最佳的陶瓷平板膜制备条件。结果表明:当烧成温度为1060℃,氧化铝膜浆固含为35%,焙烧后喷涂增重在0.4%~0.6%之间时,膜厚与膜形貌达到最优。陶瓷平板膜的孔径在90nm左右,水通量在0.3MMH。
英文摘要:
      This article used aluminum oxide plate with a sprayed transition layer as the membrane support, and used dynamic spraying method to prepare a separation membrane layer on it. The obtained samples were characterized by SEM, pore size analysis, and other methods. To explore the influence of different firing temperature, spraying weight increase and solid content of membrane slurry on the pore diameter, morphology and thickness of Ceramic membrane, and to obtain the best preparation conditions of Ceramic flat membrane. The results showed that when the sintering temperature was 1060℃, the solid content of the alumina membrane slurry was 35%, and the spray weight gain after calcination was between 0.4%~0.6%, the film thickness and morphology reached the optimal level. The pore size of the ceramic flat membrane was around 90nm, and the water flux was 0.3MMH.
