Abstract: |
The degassing performance of polyvinylidene fluoride (PVDF) hollow fiber membrane was studied in this paper with the purpose of improving deoxidizing efficiency. The influence of the inner diameter, wall thickness, module length and the surface morphology on the deoxidizing efficiency has been investigated. The result indicates that the inner diameter, the module length and the surface morphology of the membrane have a great influence on the deoxidizing efficiency. Higher inner diameter and longer module induce higher deoxidizing efficiency. The loose sponge structure of surface of membrane leads to higher deoxidizing efficiency. The effect of the wall thickness of PVDF membrane on the deoxidizing efficiency might be neglected. The hollow fiber membrane with internal coagulant of 70% DMAc, inner diameter of 0.3mm and wall thicknss of 0.15mm would be a better degassing membrane according to the deoxidizing efficiency and mechanics performance of membrane. |
