It can be concluded that the performance differences between the plate membrane and the hollow fiber membrane can be attribute to difference of the stresses in the membranes when they were under pressure and the difference of the strain caused in the membrane, besides the possible reason that the surface curvature difference between a plate substrate and a hollow fiber one may cause structure difference in the dense functional layer when coating. the stresses in a hollow fiber composite membrane under an outside pressure are quite different from that in a plate one in that they exert on the hollow fiber in both the radial and circular directions, and the compress strain of the hollow fiber is thus much more complex, which may cause the top layer crinkle and a decreased salt rejection

    分析認為造成平板復合膜( )和中空纖維復合膜( )性能差異的主要原因,除了平板基膜與中空纖維基膜因表面曲率不同可能引起在塗覆時形成的功能層結構上的差異之外,由於中空纖維膜受外壓時,膜內部承受的應力形式與平板膜不同,會同時在徑向(膜厚度方向)和向(膜面內方向)兩個方向產生壓應力,因此,所發生的形變也較為復雜,可能造成表面復合層的起皺或脫落,引起脫鹽率下降。
