Description

一种新型抗菌抗污染复合超滤膜
技术领域
本实用新型涉及一种新型抗菌抗污染复合超滤膜。
背景技术
超滤膜技术由于操作简单、分离效率高、低压、无相变和能耗低,已在水处理、石油化工、生物制药、食品加工等领域得到推广与应用。但是现有的超滤膜不具有很好的抗污染性和抗菌性能,容易使污染物在膜表面聚集,或是微生物在膜表面聚集、繁殖并形成生物粘膜,从而导致在实际的运用中膜的处理能力降低,使超滤膜处理的费用增加。
实用新型内容
本实用新型的目的在于提供抗菌抗污染复合超滤膜,能够有效克服现有超滤膜抗菌性能和抗污染能力差的问题。
为了解决上述技术问题,本实用新型是通过以下技术方案实现的:抗菌抗污染复合超滤膜,是由支撑层、抗菌超滤分离层和抗污染层紧密复合而成。
优选的,所述支撑层的材质是聚酯无纺布。
优选的,所述抗菌超滤分离层的材质是聚偏氟乙烯和纳米银颗粒。
优选的,所述抗污染层的材质是聚甲基丙烯酸羟乙酯。
与现有技术相比,本实用新型的优点是:本实用新型抗菌抗污染复合超滤膜,它的超滤分离层材质是聚偏氟乙烯和纳米银颗粒,纳米银颗粒具有良好的抗菌性能,能够有效提高超滤膜的抗菌性能,超滤分离层上再复合了一层抗污染层,能够有效提高超滤膜的抗污染性能。
附图说明
图1为本实用新型的结构示意图;
图中所示:1为支撑层,2为抗菌超滤分离层,3为抗污染层。
具体实施方式
参阅图1为本实用新型一种新型抗菌抗污染复合超滤膜的实施例,它由支撑层1、抗菌超滤分离层2和抗污染层3三层紧密复合而成,支撑层1的材质是聚酯无纺布,抗菌超滤分离层2是涂覆在支撑层1上得到的,其材质是聚偏氟乙烯和纳米银颗粒,纳米银颗粒具有良好的抗菌性能,可以赋予超滤膜优良的抗菌性能,抗污染层3复合在抗菌超滤分离层2上,其材质是聚甲基丙烯酸羟乙酯,聚甲基丙烯酸羟乙酯具有良好的抗污染性,因此在抗菌超滤分离层2上复合一层聚甲基丙烯酸羟乙酯抗污染层3后,可以赋予超滤膜好的抗污染性能。
以上所述仅为本实用新型的具体实施例,但本实用新型的技术特征并不局限于此,任何本领域的技术人员在本实用新型的领域内,所作的变化或修饰皆涵盖在本实用新型的专利范围之中。
