HOLLOW-FIBRE MEMBRANE HAVING NOVEL STRUCTURE, AND PRODUCTION METHOD THEREFOR |
摘要 |
The present invention relates to a hollow-fibre membrane having a novel structure and to a production method therefor. The hollow-fibre separation membrane of the present invention has an outermost shell surface pore size of between 0.001 and 0.05 μm and a mean pore size of between 0.01 and 0.1 μm while having, in sequence from the outermost shell surface, a dense sponge structure, a finger-like sponge structure and a mixed sponge-bead structure; and, because of this specific triple structure, the invention has outstanding mechanical strength, porosity and water permeability alike while also having a high performance whereby it is possible to eliminate even viruses. |
