摘　　要：增强型中空纤维膜由于增强体与聚合物溶液之间不易达成理想结合效果,目前通常采用两种处理方式来增强两者的界面结合强度:一种为选择相容性好的增强体与成膜聚合物,合理调配聚合物溶液的质量分数;另外一种为对增强体进行碱处理、偶联剂处理、黏合剂整理以及等离子处理等。增强型中空纤维膜界面结合强度表征方法包括拔出强度、剪切强度、物理反冲洗、溶解度参数、拉伸法、超声清洗等。对上述不同类型增强型中空纤维膜的界面处理工艺以及增强型中空纤维膜界面结合强度的表征方法分别进行介绍和阐述。Since it is uneasy to achieve the desired bonding effect between the reinforcement and polymer solution of reinforced hollow fiber membrane the interfacial bonding strength is usually reinforced in two ways.One way is to select reinforcement material and film-forming polymer that are well compatible with each other,and prepare polymer solution of rational mass fraction.The other way is to treat reinforcement via alkali,coupling agent,adhesive,plasma,and so on.The characterization methods of the interface bonding strength of reinforced membrane include extraction strength,shear strength,physical backwashing,solubility parameters,tensile method,and ultrasonic cleaning.This study is intended to introduce and illustrate the aforesaid interface treatment processes of reinforced hollow fiber membrane and characterization methods of interface bonding strength respectively.
