| 摘要 |
<p>The present invention relates to a hollow fiber membrane manufacturing method, comprising the steps of injecting a spinning solution consisting of polyvinylidene fluoride (PVDF), dimethylacetamide (DMAC) which is a solvent, lithium chloride (LiCl) which is a porosity forming agent and zinc chloride which is a porosity growing inhibitor to a first storage tank; injecting poly ethylene glycol (PEG) which is an additive to a second storage tank; and a preparation step of storing water or dimethylacetamide (DMAC) which is an internal coagulating solution in a third storage tank, thereby enabling manufactured hollow fiber membranes to treat water processes in a stable manner and leading to the reduction of production and maintenance cost of water treatment, and a hollow fiber membrane using the same.</p> |
