Yuav ua li cas khaws rov qab osmosis membrane ntsiab

1. Tshiab membrane ntsiab

• Cov ntsiab lus ntawm daim nyias nyias tau raug kuaj rau cov dej nkag ua ntej tawm hauv lub hoobkas, thiab khaws cia nrog 1% sodium sulfite tov, thiab tom qab ntawd lub tshuab nqus tsev ntim nrog cov hnab ntim oxygen;
• Cov txheej membrane yuav tsum tau khaws cia ntub txhua lub sijhawm. Txawm hais tias nws yuav tsum tau qhib nws 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;
• Cov khoom siv membrane yog qhov zoo tshaj plaws khaws cia ntawm qhov kub qis ntawm 5 ~ 10 ° Thaum khaws cia hauv ib puag ncig nrog qhov kub ntawm ntau tshaj 10 ° C, xaiv qhov chaw muaj cua zoo, thiab tsis txhob tshav ntuj ncaj qha, thiab qhov ntsuas kub yuav tsum tsis pub tshaj 35 ° C;
• Yog hais tias lub membrane caij freezes, nws yuav raug puas ntsoog lub cev, yog li siv rwb thaiv tsev ntsuas thiab tsis txhob khov nws;
• Thaum stacking membrane cov ntsiab lus, tsis txhob ntim ntau tshaj 5 txheej ntawm lub thawv, thiab xyuas kom meej tias lub thawv yuav qhuav.

2. Siv cov khoom siv membrane

• Cov txheej membrane yuav tsum tau khaws cia rau hauv qhov chaw tsaus txhua lub sijhawm, qhov ntsuas kub yuav tsum tsis pub tshaj 35 ° C, thiab nws yuav tsum zam los ntawm tshav ntuj ncaj qha;
• Muaj kev pheej hmoo ntawm kev khov thaum qhov kub thiab txias qis dua 0 ° C, yog li kev ntsuas tiv thaiv yuav tsum tau ua;
• Txhawm rau tiv thaiv kev loj hlob ntawm cov kab mob hauv lub sijhawm luv luv, kev thauj mus los thiab kev ua haujlwm, nws yog ib qho tsim nyog los npaj sodium sulfite (qib zaub mov) tiv thaiv kev daws teeb meem nrog rau qhov concentration ntawm 500 ~ 1,000ppm thiab pH3 ~ 6 kom ntub cov khoom nrog dej ntshiab lossis rov qab osmosis ua dej. Feem ntau, Na2S2O5 yog siv, uas reacts nrog dej los tsim bisulfite: Na2S2O5 + H2O —
• Tom qab soaking lub membrane caij nyob rau hauv lub preservation tov rau li 1 teev, tshem tawm cov membrane cov ntsiab lus los ntawm cov tshuaj thiab ntim rau hauv ib lub hnab ntim oxygen, muab lub hnab ntim thiab sau nws nrog hnub ntim.
• Tom qab cov txheej txheem membrane yuav tsum tau muab ntim rov qab, cov txheej txheem khaws cia yog tib yam li cov khoom tshiab membrane.
• Cov concentration thiab pH ntawm cov tshuaj khaws cia yuav tsum tau khaws cia nyob rau hauv ntau yam saum toj no, thiab nws yuav tsum tau xyuas tsis tu ncua, thiab yog hais tias nws yuav deviate los ntawm cov saum toj no ntau yam, cov preservation tov yuav tsum tau npaj dua;
• Txawm li cas los xij, nyob rau hauv uas lub membrane khaws cia, lub membrane yuav tsum tsis txhob cia qhuav.
• Tsis tas li ntawd, qhov concentration (piv txwv li concentration) ntawm 0.2 ~ 0.3% formaldehyde tov kuj tseem siv tau los ua cov tshuaj khaws cia. Formaldehyde yog cov tshuaj tua kab mob microbial muaj zog dua li sodium bisulfite thiab tsis muaj oxygen.
