Kusungidwa Kwa Membrane Yopanda Madzi Ndi Yopumira
Nembanembayo ikasungidwa kwa nthawi yayitali, iyenera kukhalabe yogwira ntchito bwino komanso kukhala ndi phindu, kotero kuti moyo wa nembanemba wosalowa madzi komanso wopumira ndi chinthu chofunikira. Choncho, chidwi chapadera chiyenera kuperekedwa ku yosungirako kwenikweni.
Kusungidwa kwa nembanemba ya microfiltration yosalowa madzi komanso yopumira imagawidwa m'njira ziwiri: kusungirako kunyowa ndi kusungidwa kouma. Mulimonse momwe zingakhalire, cholinga chake ndikuletsa nembanemba kuti isakhale ndi hydrolyzed, kuteteza kukula ndi kukokoloka kwa tizilombo tating'onoting'ono, komanso kuchepa ndi kusinthika kwa nembanemba.
Chinsinsi cha kusungirako kunyowa ndikusunga nthawi zonse pamwamba pa nembanemba ndi njira yosungira mumkhalidwe wonyowa. Njira zotsatirazi zitha kugwiritsidwa ntchito posungira: madzi: glycerin: formaldehyde = 79.5:20:0.5. Ntchito ya formaldehyde ndikuletsa kukula ndi kubereka kwa tizilombo toyambitsa matenda pamwamba pa nembanemba ndikuletsa kukokoloka kwa nembanemba. Cholinga chowonjezera glycerin ndikuchepetsa kuzizira kwa njira yosungiramo ndikuletsa nembanemba kuti isawonongeke ndi kuzizira. The formaldehyde mu chilinganizo angathenso m'malo ndi fungicides ena monga mkuwa sulphate kuti si zovulaza nembanemba. Kutentha kosungirako kwa cellulose acetate membrane ndi 5-40 ° C ndi PH = 4.5 ~ 5, pamene kutentha kosungirako ndi pH ya non-cellulose acetate membrane ikhoza kukhala yotakata.
Dry Preservation
Ma membrane a microfiltration osalowa madzi komanso opumira nthawi zambiri amaperekedwa pamsika ngati ma membrane owuma chifukwa ndiosavuta kusunga ndikunyamula. Kuonjezera apo, filimu yonyowa iyenera kusungidwa mu njira youma, ndipo njira zotsatirazi ziyenera kugwiritsidwa ntchito pokonza filimuyo isanayambe. Njira yeniyeni ndi: cellulose acetate nembanemba imatha kuviikidwa mu 50% glycerin amadzimadzi njira kapena 0,1% sodium lauryl sulfonate amadzimadzi njira kwa masiku 5 mpaka 6, ndi zouma pa wachibale chinyezi 88%. The polysulfone nembanemba akhoza zouma kutentha firiji ndi yankho la 10% glycerin, sulfonated mafuta, polyethylene glycol, etc. monga dehydrating wothandizira. Kuphatikiza apo, ma surfactants amakhalanso ndi zotsatira zabwino pakuteteza ma pores a filimuyo kuti asawonongeke.
Chachiwiri, kukonzanso ndi kukonza kachipangizo kamene kamakhala ndi madzi komanso mpweya wopumira kuyenera kutsatiridwa
Kusamalira ndi kusamalira kachitidwe ka nembanemba kuyenera kuyang'ana pa zinthu zotsatirazi.
① Malinga ndi nembanemba zosiyanasiyana, chidwi chapadera chiyenera kuperekedwa kumalo ogwiritsira ntchito, makamaka kutentha ndi pH yamadzimadzi, komanso chlorine zomwe zili mumadzimadzi.
② Pamene nembanemba imayimitsidwa kwakanthawi kochepa, chidwi chiyenera kulipidwa pakusungidwa kwa chinyezi cha nembanemba, chifukwa pomwe nembanemba imataya madzi, palibe njira yothetsera, ma pores osalowa madzi komanso opumira amatha kufota ndikuwonongeka. zidzachepetsa kugwira ntchito kwa membrane.
③Mukayimitsa, pewani kukhudzana ndi zakumwa zodzaza kwambiri.
④ Sambani ndi kusunga nembanemba nthawi zonse ndi madzi okonzera kuti muchepetse kuipitsidwa kwa membrane.
⑤ Pogwiritsidwa ntchito, gwirani ntchito molingana ndi machitidwe omwe makina a membrane amatha kupirira kuti asachuluke.
