Kev tswj xyuas zoo ntawm tubular ultrafiltration membranes yog kev sib koom ua ke thoob plaws hauv tag nrho cov txheej txheem, los ntawm kev xaiv cov khoom siv thiab cov txheej txheem tsim khoom kom tiav cov khoom kuaj thiab kev tswj xyuas. Nws yog qhov kev lees paub tseem ceeb rau kev ua kom ntseeg tau tias lawv cov kev sib cais sib cais, lub zog siv tshuab, thiab kev ua haujlwm ntev - lub sijhawm ua haujlwm ruaj khov. Hauv cov xwm txheej uas cuam tshuam nrog cov khib nyiab siab, siab viscosity, thiab cov kev daws teeb meem, txawm tias qhov sib txawv me me hauv daim nyias nyias tuaj yeem cuam tshuam ncaj qha rau cov kab mob flux, kev tsis lees paub, thiab kev ua neej nyob. Yog li ntawd, tsim kom muaj ib tug systematic thiab quantifiable zoo tswj system yog ib qho tseem ceeb heev.
Raw khoom zoo yog thawj kab ntawm kev tiv thaiv hauv kev tswj kom zoo. Muaj ntau hom ntaub ntawv membrane, nrog rau cov khoom siv organic xws li polyethersulfone thiab polyvinylidene fluoride, thiab cov ntaub ntawv inorganic xws li alumina thiab zirconium oxide. Lawv qhov hnyav molecular faib, crystallinity, thiab impurity cov ntsiab lus cuam tshuam rau cov membrane uniformity thiab tshuaj tiv thaiv. Txhua batch ntawm raw cov ntaub ntawv yuav tsum raug kuaj rau physicochemical zog los xyuas kom meej ua raws li cov formulation yuav tsum tau thiab tsis txhob membrane pore loj deviations los yog tsis txaus txhua yam lub zog los ntawm raw khoom fluctuations.
Cov txheej txheem tswj nyob rau hauv cov txheej txheem tsim khoom txiav txim siab qhov rov ua dua ntawm cov qauv membrane thiab kev ua haujlwm. Ua ib qho piv txwv ntawm kev hloov pauv ntub dej, qhov concentration, viscosity, kub, thiab qhov sib ntxiv ntawm cov tshuaj casting yuav tsum tau tswj nruj me ntsis. Lub txheej thickness thiab coagulation da dej tej yam kev mob yuav tsum tau khaws cia tas li; txwv tsis pub, qhov tsis sib xws ntawm qhov pore loj faib nyob rau hauv cov txheej txheem sib cais thiab nrawm nrawm nrawm yuav tshwm sim. Lub winding nro ntawm lub raj txhawb nqa thiab sintering kub profile (rau ceramic membranes) kuj yuav tsum tau saib xyuas nyob rau lub sijhawm tiag tiag kom ntseeg tau tias muaj kev ruaj khov ntawm kev txhawb nqa txhua yam thiab txheej txheej membrane.
Kev tshuaj xyuas cov khoom tiav yog ib kauj ruam tseem ceeb hauv kev txheeb xyuas qhov zoo. Cov khoom niaj hnub muaj xws li kev tshuaj xyuas qhov muag, ntsuas qhov tseeb qhov tseeb, kev txiav txim siab dej ntshiab, thiab kev ntsuas qhov tsis lees paub. Kev ntsuas qhov tsis lees paub feem ntau siv cov qauv tshuaj xws li polyethylene glycol (PEG) thiab bovine serum albumin (BSA) raws li cov ntaub ntawv pov thawj los xyuas kom meej tias qhov kev tsis lees paub raws li qhov kev ntsuas siab sib phim tus nqi tsim. Kev ntsuas kev ua tau zoo suav nrog kev tawg siab, lub zog compressive, thiab qhov kub thiab txias los txiav txim siab qhov kev nyab xeeb ntawm daim nyias nyias raws li qhov hloov pauv ntawm kev ua haujlwm. Rau cov khoom siv ceramic, kev tsom xam ntawm cov porosity thiab pore loj faib yuav tsum tau ua kom ntseeg tau tias cov qauv ntau - theem channel raws li cov qauv tsim.
Kaw-Txoj kev tswj kev tswj kom zoo yog qhov tseem ceeb sib npaug. Lub batch traceability system yuav tsum tau tsim, txuas thiab archiving raw khoom qhov chaw, txheej txheem tsis, xeem tau, thiab tus neeg teb xov tooj ntaub ntawv. Qhov no tso cai rau kev txheeb xyuas sai thiab kho kom raug thaum muaj kev tsis txaus ntseeg. Kev tshuaj xyuas tsis tu ncua thiab kev ntsuas kev muaj peev xwm ntawm cov txheej txheem (xws li kev tshuaj xyuas CPK) tuaj yeem txheeb xyuas qhov muaj peev xwm hloov pauv thiab ua kom muaj kev txhim kho txuas ntxiv.
Los ntawm kev tswj xyuas kom zoo thoob plaws hauv tag nrho cov txheej txheem, tubular ultrafiltration membranes tuaj yeem tswj tau siab flux, muaj peev xwm tuav tau, thiab lub neej ntev nyob rau hauv kev ua haujlwm nyuaj, muab kev ruaj ntseg ruaj khov rau kev ua haujlwm ruaj khov hauv kev kho dej, zaub mov, tshuaj, thiab tshuaj lom neeg kev lag luam, thiab ntxiv dag zog rau cov khoom lag luam lub koob npe nrov thiab kev sib tw hauv kev lag luam.
