| 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. |
