Hauv kev ua kua purification thiab cov peev txheej rov qab los, hollow fiber ultrafiltration membranes, nrog lawv cov qauv tshwj xeeb thiab kev ua tau zoo tshaj, tau dhau los ua cov khoom tseem ceeb ntawm kev sib cais niaj hnub. Ua los ntawm cov ntaub ntawv polymer los ntawm cov txheej txheem tshwj xeeb, lawv muaj cov qauv hollow fiber ntau, tsim suav tsis txheeb micropores nrog lub pore loj feem ntau ntawm 0.01 txog 0.1 micrometers. Qhov no tso cai rau kev khaws cia ntawm cov kab mob, colloids, cov organic molecules loj, thiab cov khoom raug tshem tawm, thaum tso cai rau dej thiab cov kua dej me me kom dhau mus dawb, ua tiav cov khoom muaj txiaj ntsig zoo - kua sib cais.
Los ntawm cov qauv kev xav, ultra- txoj kab uas hla zoo (ntau txog rau pua pua micrometers) thiab qhov chaw siab ntawm qhov hollow fibers muab cov txiaj ntsig zoo rau lawv: thaj chaw pom zoo rau ib chav tsev ntim deb tshaj li ntawm cov tsoos tiaj tus- daim ntawv membranes, ua rau cov cuab yeej me me rau tib lub peev xwm ua haujlwm; tus kheej- txhawb nqa fiber ntau cov qauv ua kom yooj yim rau kev ntim khoom, txo kev ua haujlwm tsis zoo, thiab txhim kho flux thiab tiv thaiv - fouling peev xwm. Tsis tas li ntawd, kev hloov kho hydrophilic thev naus laus zis ntxiv txhim kho kev tiv thaiv kev tiv thaiv - fouling kev ua tau zoo thiab txuas ntxiv lub voj voog ua haujlwm ruaj khov.
Cov cuab yeej no muaj ntau yam kev siv, suav nrog kev kho dej, khoom noj thiab tshuaj, thiab bioengineering. Hauv kev kho dej, nws tuaj yeem siv los ua ib chav pretreatment rau thim rov qab osmosis kom tshem tawm turbidity thiab kab mob, ua kom muaj kev nyab xeeb ntawm cov tshuab tom ntej. Hauv kev lag luam khoom noj khoom haus, nws yog siv rau whey protein concentration thiab kua txiv kom meej meej, ntsuas qhov zoo khaws cia thiab tswj kev siv hluav taws xob. Nyob rau hauv biopharmaceutical teb, nws pab nyob rau hauv cov tshuaj tiv thaiv purification thiab fermentation broth sib cais, ua tau raws li cov kev cai siab huv. Piv nrog rau txoj kev pom ib txwm siv, nws chav - kub ua haujlwm thiab tsis muaj theem hloov ua kom nws haum rau tuav cov cua sov- cov khoom rhiab heev. Tsis tas li ntawd, nws cov tshuaj muaj zog ruaj khov tso cai rau rov siv dua los ntawm kev ntxuav thiab rov tsim dua tshiab, txo cov nqi tag nrho lub neej.
Nrog rau kev nce qib hauv cov ntaub ntawv kev tshawb fawb thiab kev tsim khoom, hollow fiber ultrafiltration membranes yog iterating rau siab dua flux, tsis kam mus rau muaj zog acids thiab alkalis, thiab ntev lifespan. Raws li tus neeg sawv cev ntawm cov cuab yeej sib cais ntsuab, nws txuas ntxiv txhawb nqa cov peev txheej dej rov ua dua tshiab, kev tsim khoom tsim khoom huv si, thiab kev kho dua tshiab ntawm kev tsim khoom siab - kawg, ua lub luag haujlwm tsis hloov pauv hauv kev tsim kho kev lag luam.
