Kev sib cais efficiency thiab lifespan ntawm hollow fiber ultrafiltration membranes fundamentally nyob ntawm cov khoom xaiv thiab kev ua tau zoo optimization. Tam sim no, cov ntaub ntawv tseem ceeb hauv kev lag luam poob rau hauv ob pawg: organic polymers thiab inorganic ceramics, txhua tus muaj nws tus yam ntxwv thiab tsim nyog rau ntau yam kev thov.
Organic polymer cov ntaub ntawv yog cov khoom siv dav tshaj plaws vim lawv qhov yooj yim ntawm kev ua thiab tus nqi qis. Polysulfone (PSF) yog ib qho piv txwv zoo, muaj lub zog zoo heev thiab tshuaj lom neeg ruaj khov, qhov kub thiab txias ntau yam (-}10℃txog 80 degree), thiab ua haujlwm zoo rau feem ntau cov kua qaub, alkalis, thiab oxidants, feem ntau siv los ua cov txheej txheej membrane. Polyethersulfone (PES) ua tau zoo nyob rau hauv hydrophilicity thiab flux, thiab nws cov yam ntxwv tsis tshua muaj protein adsorption ua rau nws siv dav hauv biopharmaceuticals thiab zaub mov thiab dej purification. Polyacrylonitrile (PAN) muaj zog hydrophilicity thiab zoo antifouling muaj peev xwm, haum rau kho oily wastewater los yog tsawg -turbidity dej qhov chaw. Cellulose acetate (CA) muaj biocompatibility zoo heev thiab tau pib siv rau kev ua tshuaj purification, tab sis nws qhov kub thiab pH adaptability kuj tsis muaj zog, thiab nws yog maj mam hloov los ntawm cov ntaub ntawv tshiab. Hloov kho polyvinylidene fluoride (PVDF), uas tau tshwm sim nyob rau hauv xyoo tas los no, txhim kho hydrophilicity los ntawm kev sib xyaw los yog nto grafting, thaum tseem nthuav tawm ntev -lub sij hawm ruaj khov tiv thaiv cov kua qaub thiab alkalis thiab chlorine oxidation, ua rau nws yog qhov kev xaiv zoo tshaj plaws hauv kev kho dej siab.
Inorganic materials, represented by ceramics such as alumina and zirconium oxide, are suitable for material separation under extreme conditions due to their ultra-high mechanical strength, high temperature resistance (>200 degree), thiab muaj zog corrosion kuj, xws li siab -kub fermentation broth kho los yog purification ntawm muaj zog acid / alkali media. Txawm li cas los xij, lawv cov nqi tsim khoom siab thiab brittleness txwv lawv qhov loj -scale saws.
Kev xaiv cov khoom yuav tsum muaj kev xav txog cov yam ntxwv ntawm cov kua dej pub, kev ua haujlwm, thiab kev lag luam: cov organic membranes ua tau zoo tshaj plaws hauv kev yooj yim thiab tus nqi -kev ua tau zoo, dominating pa kev kho dej thiab kev ua zaub mov; inorganic membranes, ntawm qhov tod tes, yog positioned nyob rau hauv tshwj xeeb teb vim lawv durability. Nyob rau hauv lub neej yav tom ntej, optimizing cov khoom vaj tse los ntawm technologies xws li nanocompositing thiab biomimetic kev hloov kho yuav ntxiv nthuav daim ntawv thov ciam teb ntawm hollow fiber ultrafiltration membranes, muab kev daws zoo dua rau kev sib cais ntawm complex systems.
