Kev xaiv ntawm Ultrafiltration Membrane Pob hauv Tangential Flow Filtration
Kev xaiv ntawm cov ntaub ntawv ultrafiltration membrane tau ua rau cov kws tshawb fawb feem ntau xav tsis thoob, tshwj xeeb tshaj yog cov neeg uas nyuam qhuav tau ntsib nrog TFF. Kev xaiv ntawm cov membrane tsim nyog yog lub hauv paus ntawm tangential ntws sim.
Ultrafiltration membrane plays lub luag haujlwm lim hauv cov qauv cortical heev. Feem ntau, nws yog ib qho nyuaj rau me me molecules nkag mus rau hauv lub lim membrane. Yog li ntawd, ultrafiltration membrane feem ntau yog cov kuab paug nyob rau saum npoo ntawm daim nyias nyias. Yog li ntawd, nws yog ib qho tsim nyog los tswj tus nqi ntws thaum ua haujlwm ultrafiltration. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws yuav tsum yaug lub ntsej muag ntawm lub lim membrane, txhim kho lub siab kom kho qhov pom kev nrawm.
Dab tsi ntawm daim nyias nyias yog qhov zoo tagnrho ultrafiltration membrane? Nws tuaj yeem pom los ntawm cov duab hluav taws xob tshuab hluav taws xob uas cov yeeb yaj kiab txheej txheej yog nyias thiab sab hauv txoj kab uas hla ntawm cov txheej txheem txhawb nqa yog loj, thiaj li ua kom pom kev ceev ceev, siab txaus thiab siab txaus. Cov hauv paus. Nyob rau tib lub sijhawm, nws coj qhov muaj peev xwm ntawm elasticity. Rau cov molecules uas xav tau siab npaum li cas, tus nqi ntws tuaj yeem nce ntxiv, thaum rau cov molecules uas tsis xav tau siab txaus, tus nqi ntws tuaj yeem raug txo kom tsim nyog.
Qhov loj qhov pore loj ntawm cov txheej txheem txhawb nqa kom tsim nyog txo qhov kev ua haujlwm siab thiab txo qhov kev puas tsuaj rau cov khoom siv molecules, txhawm rau txhawb kev ua kom huv thiab muaj zog ntawm cov khoom siv biomolecules.
Los ntawm qhov kev xav ntawm kev rov ua dua tshiab, cov txheej txheem txhawb nqa muaj lub qhov pore loj thiab tuaj yeem ua kom huv si ntawm qhov kub thiab txias. Nyob rau tib lub sijhawm, kev tu kom zoo thiab kev rov zoo tuaj yeem ua tiav. Yog hais tias lub pore txoj kab uas hla ntawm cov txheej txheem yog me me, qhov ntsuas kub yuav tsum tau nce ntxiv. Nyob rau tib lub sijhawm, qhov muaj peev xwm ntawm kev tu tsis ua haujlwm yog siab, uas txhais tau hais tias qhov kev pheej hmoo ntawm kev ua qias tuaj ntau zuj zus, thiab tus nqi rov qab tsis tuaj yeem lav tau rau lub sijhawm no.
