1. Cov txheej txheem membrane tshiab
(1) Cov ntsiab lus Membrane tau raug kuaj ua ntej xa khoom, thiab siv 1 feem pua sodium sulfite tov rau kev kho cia, thiab tom qab ntawd nrog cov pa oxygen cais lub hnab nqus tsev ntim khoom.
(2) Cov txheej membrane yuav tsum tau khaws cia noo txhua lub sijhawm. Txawm hais tias nws yuav tsum tau qhib ib ntus txhawm rau txhawm rau paub meej tias qhov ntau ntawm tib lub pob, nws yuav tsum tau ua nyob rau hauv lub xeev uas tsis ua rau lub hnab yas puas, thiab lub xeev no yuav tsum tau khaws cia kom txog thaum lub sijhawm siv.
(3) Membrane ntsiab yog qhov zoo tshaj plaws khaws cia hauv 5 ~ 10 degree ntawm qhov kub thiab txias. Thaum khaws cia rau hauv ib qho chaw uas qhov kub thiab txias tshaj 10 degree, xaiv qhov chaw uas muaj cua zoo thiab tsis txhob tshav ntuj ncaj qha. Qhov kub cia yuav tsum tsis pub tshaj 35 degree.
(4) Yog tias cov khoom siv membrane khov, lub cev puas tsuaj yuav tshwm sim, yog li kev ntsuas rwb thaiv tsev yuav tsum tau ua, tsis txhob ua kom khov.
(5) Thaum stacking membrane cov khoom, lub thawv ntim yuav tsum tsis pub tshaj 5 txheej thiab xyuas kom meej tias cov thawv ntim tau qhuav.
2. Siv cov khoom siv membrane
(1) Membrane cov ntsiab lus yuav tsum nco ntsoov khaws cia rau hauv qhov chaw tsaus, qhov ntsuas kub tsis tshaj 35 degree, thiab kom tsis txhob muaj hnub ci ncaj qha.
(2) Muaj kev pheej hmoo ntawm kev khov thaum qhov kub thiab txias qis dua 0 degree, yog li yuav tsum tau ntsuas kev tiv thaiv kom khov.
(3) Txhawm rau tiv thaiv microbial kev loj hlob ntawm cov khoom siv membrane thaum lub sij hawm luv luv cia, kev thauj mus los, thiab qhov system standby, sodium sulfite (khoom noj khoom haus qib) tiv thaiv kev daws teeb meem nrog concentration ntawm 500 ~ 1, 000ppm, pH3 ~ 6, yog npaj nrog dej ntshiab los yog rov qab osmosis cov dej ntau lawm. Feem ntau, Na2S2O5 yog siv, uas reacts nrog dej los tsim bisulfite: Na2S2O5 ntxiv rau H2O -- 2NaHSO3.
(4) Tom qab soaking lub membrane caij nyob rau hauv lub preservation tov rau li 1 teev, tshem tawm cov membrane caij los ntawm cov tshuaj thiab ntim rau hauv ib lub hnab ntim oxygen. Kaw lub hnab thiab sau nws nrog hnub ntim.
(5) Tom qab cov txheej membrane yuav tsum tau txais kev cawmdim yog repackaged, preservation tej yam kev mob yog zoo ib yam nrog cov tshiab membrane caij.
(6) Cov concentration thiab pH ntawm cov tshuaj khaws cia yuav tsum tau khaws cia rau hauv ntau yam saum toj no, uas yuav tsum tau kuaj xyuas tsis tu ncua. Yog hais tias sib txawv los ntawm ntau yam saum toj no yog ua tau, cov tshuaj preservation yuav tsum tau modulated dua.
(7) Nyob rau hauv tsis muaj qhov xwm txheej yuav tsum tau muab cov membrane tso rau hauv lub xeev qhuav kom khaws cia.
(8) Tsis tas li ntawd, formaldehyde tov nrog concentration (ntau feem pua concentration) ntawm 0.2-0.3 feem pua kuj siv tau raws li preservation tov. Formaldehyde yog cov tshuaj tua kab mob microbial muaj zog dua li sodium bisulfite thiab tsis muaj oxygen.
