Description
技术领域
本发明涉及一种EDI专用膜生产配方。
背景技术
填充床电渗析除盐器(简称EDI)用异相离子交换膜,以其优异独特的技术性能将电渗析技术与离子交换技术相融合,无需酸碱处理连续制取高纯水,广泛用于半导体工业、发电工业、工业锅炉用水的进水、电子、医药、生物技术等行业,以及实验室用水。该产品的研制成功和推广应用,意味着异相离子交换膜的应用领域向高层次推进,开创了膜分离技术的又一大变革。
EDI膜含有足够的固定基团和可解离的离子,对溶液中离子具有选择透过性和导电性,其次,以高度致密性,极大地减小了水的渗透率和盐的扩散量。阳膜具有强酸性活性交换基团R-SO3-(构成负电场)和可解离离子H+,带正电荷的离子易吸收通过;阴膜具有强碱性活性交换基团R-CH2N+(CH3)3(构成正电场)和可解离离子Cl-,带负电荷的离子易吸收通过。
