本文主要研究内容
作者王博（2019）在《不锈钢复合过滤膜的制备及其乳化液分离性能研究》一文中研究指出：传统油水乳化液分离方法需要外加驱动力,过程繁杂,研究新型乳化液分离技术势在必行,膜分离技术的快速发展,为油水分离提供了便捷。本文采用简单化学氧化聚合法、化学沉积法和低温水热合成法,在不锈钢网表面构建粗糙结构,制备超亲水/水下超疏油涂层不锈钢网,用于油水分离和水包油型乳化液分离。采用化学氧化聚合法在不锈钢网表面聚合生长微纳米聚吡咯涂层,在空气中具有超双亲性,水下三氯甲烷接触角为158.5°±1.5°,经强酸、强碱和饱和食盐水溶液浸泡24 h后,仍保持良好水下超疏油性,涂层稳定性好。在重力下,可以有效地从各种油水混合物中分离出油或水,分离效率大于97%,在各种恶劣环境下具有良好的可循环利用性,30次循环后分离效率为95.8%。FeCl3作为氧化剂效果最佳,（NH4）2S2O8可快速大量制备涂层不锈钢网,适用于批量生产。用化学沉积法制备了均匀氧化钨涂层,通过浸涂二氧化钛溶胶,煅烧得到较高强度WO3/TiO2复合涂层不锈钢网,具有水下超疏油性、低粘附性,20 kPa压力下摩擦,仍保持良好水下疏油性和较高分离效率。对不同种类水包油型乳化液具有很好分离效果,分离速度较快,重力下水通量为200 L·m-2·h-1左右,0.1 MPa下水通量超过1200 L·m-2·h-1,分离效率大于98.5%,多次循环使用,分离效率大于96%。复合涂层具有良好防污塞性能,在水通量下降情况下,用酒精冲洗后,水通量可恢复到初始值。采用低温水热合成法制备氧化锌涂层,用TiO2溶胶煅烧加固,制备出超亲水/水下超疏油ZnO/TiO2复合涂层不锈钢网,水下氯仿接触角为154.5°±0.8°。TiO2在ZnO涂层表面形成一层致密氧化膜,提升了涂层耐酸、碱腐蚀性能,经酸碱溶液浸泡12小时,仍具有较好水下疏油性能。对不同种类水包油型乳化液都有较好分离效果,分离速度快,重力下水通量为500 L·m-2·h-1左右,0.05 bar下水通量超过1500 L·m-2·h-1,分离效率大于98.5%。乳化液酸碱性对分离效率影响较小,但经酸碱浸泡处理12小时后,分离效率减小,碱性浸泡后减小幅度大于酸性条件。复合涂层对血液中高血脂具有一定的分离效果。综上,PPy、WO3/TiO2和ZnO/TiO2复合涂层不锈钢网,制备工艺简单、成本低廉、无污染,为高效、绿色、快速分离油水混合物和水包油型乳化液提供有效方法,其中ZnO/TiO2复合涂层不锈钢网为实现血脂分离提供基础研究。
