美纤纳滤膜特点介绍 Introduction to the characteristics of
MAXIE nanofiltration membrane

1.高通量 1.high flow rate
在纳滤制膜过程中， During the production of nanofiltration membranes,
使用合适的添加剂，有效提高膜片亲水性； Use appropriate additives to effectively improve the hydrophilicity of the
membrane;
优化配方比例，结构均匀而疏松，进一步提
高通量。 Optimize the formula ratio, make the structure uniform and loose, and
经测试，膜片通量＞1L/㎡.min(25℃,0.25MPa)。 further increase the flow rate.
2.抗衰减，抗高压 Test results show that the membrane flow rate is >1L/㎡.min25℃,0.25MPa.
在纳滤制膜过程中， 2.Anti-attenuation, high pressure resistance
通过聚合过程中采用双相亲合的材料，使功 By using dual-phase affinity materials during the polymerization process,
能层表面更亲水，从而抗衰减； the surface of the functional layer is made more hydrophilic and thus resists
通过基膜液材料的特点，促进功能层与支撑 attenuation;
层的紧密结合，增加膜片抗压能力； Through the characteristics of the base membrane fluid material, it
3.差异化截留区分明显 promotes the close combination of the functional layer and the support
美纤纳滤膜对一价盐(NaCl)截留率很低，约15%， layer and increases the pressure resistance of the membrane.
对二价盐(MgSO4)截留率很高，约95%。可实现 3.Differential rejection is clearly distinguished
对一价盐与二价盐的明显差异化截留。由于双 The MAXIE nanofiltration membrane has a low rejection rate of monovalent
相亲合材料的选用，表面带有双相电荷，促进 salt (NaCl), about 15%, and a high rejection rate of divalent salt (MgSO4),
离子选择性通过。 about 95%. Due to the selection of dual-phase affinity materials, the surface
has dual-phase charges, which promotes the selective passage of ions.
