Abstract

Hollow fiber membranes originally developed in the 1960s for the reverse osmosis process have since then become widely used for diverse separation processes. The advantages of hollow fiber membranes include the low energy consumption, ease of operation and, among the most important ones, highly efficient operation in a small footprint (a large membrane area can be packed into a module unit). The production of hollow fiber membranes involves many spinning parameters to be controlled. The list of these parameters, in particular, includes the viscosity of the spinning solution, the design and geometric parameters of the spinneret, the extrusion speed of the polymer solution, the composition and temperature of the bore fluid, the type of external coagulant, the air gap distance, the draw ratio, etc. The effect of these parameters on the properties of hollow fiber membranes is reviewed. Research data pertaining to the modification of polymers, both commercially available and at the stage of their synthesis, are also presented in the context of membrane applications. In addition, the preparation of membranes using non-toxic or less toxic solvents is discussed.

中空纤维膜的制造：工艺参数的影响（综述）

摘要中空纤维膜最初是在 20 世纪 60 年代为反渗透工艺开发的，此后被广泛用于各种分离工艺。中空纤维膜的优点包括能耗低、操作简便，最重要的是占地面积小，运行效率高（一个模块单元可容纳大面积膜）。中空纤维膜的生产需要控制许多纺丝参数。这些参数包括纺丝溶液的粘度、喷丝板的设计和几何参数、聚合物溶液的挤出速度、孔液的成分和温度、外部凝固剂的类型、气隙距离、牵引比等。本文综述了这些参数对中空纤维膜性能的影响。在膜应用的背景下，还介绍了与聚合物改性有关的研究数据，包括市售聚合物和处于合成阶段的聚合物。此外，还讨论了使用无毒或毒性较低的溶剂制备膜的问题。
