Assigned to Ningbo Fotile Kitchen Ware Co Ltd · Expires 2022-05-17 · 4y expired

What this patent protects

一种中空纤维重金属超滤膜,其特征在于该超滤膜的原液采用PVDF、聚砜、聚醚砜、PVC、PMIA中的至少一种作为聚合物树脂,该聚合物树脂中咪唑基与环氧基。本发明还公开了一种膜组件和超滤膜的制备方法。与现有技术相比,本发明的优点在于:所得产物的重金属去除率能达到95%以上,并且同时对水中常规矿物离子Na + 、K + 、Ca 2+ 、Mg 2+ 等无法去除,因此可实现净水过程中保留常规矿物离子而去除重金属离子。
