| titleOfInvention | A kind of preparation method and preparation system of enhanced hollow fiber microfiltration membrane |
| abstract | The invention discloses a kind of preparation method and preparation system of enhanced hollow fiber microfiltration membrane.Preparation method step has：First remove the pollutant and moisture of braiding pipe surface；Woven tube is pulled into casting solution and is impregnated, then the woven tube for being impregnated with casting solution is drawn vertically upward；So that the woven tube of dip-coating casting solution is introduced into steam bath, the film surface split-phase of woven tube forms microporous barrier, and it is enhanced hollow fiber microfiltration membrane to be re-introduced into the further curing molding of coagulating bath；Enhanced hollow fiber microfiltration membrane is placed in 12 ~ 24h of rinsing in pure water, is finally placed in protection liquid after soaking 8 ~ 24h, dries.The preparation method of the present invention can ensure the uniformity of woven tube surface coating layer, can the thickness of quick regulation coat, film and woven tube adhesion strength.Stable production process is reliable, and production exercise stool control mode is prompt, will not seriously affect film wire quality.Preparation system eliminates the expense of spinning head, has saved cost；The work that spinning head is adjusted and cleaned is eliminated, labor strength is reduced, has saved human cost. |
