Diatomite porous ceramics prepared by a foam-gelcasting route were used as a matrix, and SiO2 microspheres in-situ formed by a solvothermal method were used to modify the surface roughness of diatomite porous ceramics. Capstone FS-50 (CS-50) was used as a modifier to prepare SiO2 microspheres and CS-50 co-modified superhydrophilic-superoleophobic diatomite porous ceramics (SSMDPC) for the use of continuous separation of oil/water emulsions. The effects of TEOS/NH3·H2O addition and CS-50 concentration on the microstructure and wettability of the obtained samples as well as the oil/water separation continuous performance and extreme environmental stability were investigated. The results show that the maximum oil contact angles in air and water of the prepared SSMDPC are 153° and 158° respectively at TEOS/NH3·H2O addition of 5%/2% and CS-50 addition of 5% respectively. The continuous separation flux and separation efficiency of SSMDPC for edible oil/water mixture and edible oil-in-water emulsion with a surfactant (5/95, mass ratio) are 162.3 kg·min-1·m-2 and 98.3%, 93.7 kg·min-1·m-2 and 91.3%, respectively. Moreover, SMDPC can still maintain stable hydrophilic and hydrophobic properties under corrosion conditions (i.e., pH value of 1, pH value of 14 and 1 M NaCl), even at -196 ℃ and 200 ℃, which has broad application prospects in oil-in-water emulsion.

以发泡-注凝工艺所制备的硅藻土多孔陶瓷为基体,借助溶剂热法原位生成的SiO2微球提高硅藻土多孔陶瓷的表面粗糙度,以Capstone FS-50(CS-50)为改性剂改变多孔陶瓷的润湿状态,制备可用于油水乳液连续分离的SiO2微球和CS-50共改性的超亲水-超疏油硅藻土多孔陶瓷(SSMDPC),研究了TEOS和NH3·H2O加入量及CS-50溶液的浓度对所制备改性试样微观形貌、润湿性及油水分离性能的影响。研究表明:SSMDPC在空气中和水下的油接触角最高分别可达153°和158°;其最佳制备工艺条件如下:TEOS和NH3·H2O加入量及CS-50溶液的掺杂量分别为5%(体积分数)和2%及5%。SSMDPC对食用油/水混合液体及食用油/水乳液(5∶95,质量比)的连续分离通量和分离效率分别为162.3 kg·min-1·m-2和98.3%、93.7 kg·min-1·m-2和91.3%;SSMDPC在pH=1、pH=14、1 mol/L NaCl、-196 ℃及200 ℃的条件下,仍能保持稳定的亲水疏油性,说明其在油水乳液分离方面具有广阔的应用前景。

以发泡-注凝工艺所制备的硅藻土多孔陶瓷为基体,借助溶剂热法原位生成的SiO2微球提高硅藻土多孔陶瓷的表面粗糙度,以Capstone FS-50(CS-50)为改性剂改变多孔陶瓷的润湿状态,制备可用于油水乳液连续分离的SiO2微球和CS-50共改性的超亲水-超疏油硅藻土多孔陶瓷(SSMDPC),研究了TEOS和NH3·H2O加入量及CS-50溶液的浓度对所制备改性试样微观形貌、润湿性及油水分离性能的影响。研究表明:SSMDPC在空气中和水下的油接触角最高分别可达153°和158°;其最佳制备工艺条件如下:TEOS和NH3·H2O加入量及CS-50溶液的掺杂量分别为5%(体积分数)和2%及5%。SSMDPC对食用油/水混合液体及食用油/水乳液(5∶95,质量比)的连续分离通量和分离效率分别为162.3 kg·min-1·m-2和98.3%、93.7 kg·min-1·m-2和91.3%;SSMDPC在pH=1、pH=14、1 mol/L NaCl、-196 ℃及200 ℃的条件下,仍能保持稳定的亲水疏油性,说明其在油水乳液分离方面具有广阔的应用前景。

Diatomite porous ceramics prepared by a foam-gelcasting route were used as a matrix, and SiO2 microspheres in-situ formed by a solvothermal method were used to modify the surface roughness of diatomite porous ceramics. Capstone FS-50 (CS-50) was used as a modifier to prepare SiO2 microspheres and CS-50 co-modified superhydrophilic-superoleophobic diatomite porous ceramics (SSMDPC) for the use of continuous separation of oil/water emulsions. The effects of TEOS/NH3·H2O addition and CS-50 concentration on the microstructure and wettability of the obtained samples as well as the oil/water separation continuous performance and extreme environmental stability were investigated. The results show that the maximum oil contact angles in air and water of the prepared SSMDPC are 153° and 158° respectively at TEOS/NH3·H2O addition of 5%/2% and CS-50 addition of 5% respectively. The continuous separation flux and separation efficiency of SSMDPC for edible oil/water mixture and edible oil-in-water emulsion with a surfactant (5/95, mass ratio) are 162.3 kg·min-1·m-2 and 98.3%, 93.7 kg·min-1·m-2 and 91.3%, respectively. Moreover, SMDPC can still maintain stable hydrophilic and hydrophobic properties under corrosion conditions (i.e., pH value of 1, pH value of 14 and 1 M NaCl), even at -196 ℃ and 200 ℃, which has broad application prospects in oil-in-water emulsion.
