Ajiya Mai hana ruwa ruwa Da Membrane Mai Numfashi
Lokacin da aka adana membrane na dogon lokaci, dole ne ya kula da aiki mai kyau kuma yana da darajar amfani, don haka rayuwar mai hana ruwa da numfashi mai mahimmanci abu ne mai mahimmanci. Saboda haka, ya kamata a biya kulawa ta musamman ga ainihin ajiya.
Ana adana membrane na microfiltration mai hana ruwa da numfashi zuwa hanyoyi biyu: adana rigar da bushewa. Ko ta yaya, manufar ita ce hana membrane daga kasancewa mai ruwa, hana girma da yashwar kwayoyin halitta, da raguwa da nakasar membrane.
Makullin kiyaye rigar shine a koyaushe a kiyaye farfajiyar membrane tare da maganin adanawa a cikin yanayin ɗanɗano. Ana iya amfani da wannan dabarar don maganin adanawa: ruwa: glycerin: formaldehyde = 79.5: 20: 0.5. Matsayin formaldehyde shine don hana girma da haifuwa na ƙananan ƙwayoyin cuta a saman membrane da kuma hana yashwar membrane. Makasudin ƙara glycerin shine don rage wurin daskarewa na maganin adanawa da kuma hana membrane daga lalacewa ta hanyar daskarewa. The formaldehyde a cikin dabara kuma za a iya maye gurbinsu da wasu fungicides kamar jan karfe sulfate da cewa ba cutarwa ga membrane. Matsakaicin zafin jiki na cellulose acetate membrane shine 5-40 ° C da PH = 4.5 ~ 5, yayin da yawan zafin jiki da pH na ƙwayar acetate ba cellulose ba zai iya zama fadi.
Tsarewar bushewa
Ana samar da membranes na microfiltration mai hana ruwa da numfashi a cikin kasuwa azaman busassun membranes saboda suna da sauƙin adanawa da jigilar su. Bugu da ƙari, dole ne a adana fim ɗin da aka jika ta hanyar bushewa, kuma dole ne a yi amfani da hanyoyi masu zuwa don sarrafa fim ɗin kafin a ci gaba. Hanya ta musamman ita ce: ana iya jiƙa membrane acetate cellulose a cikin 50% glycerin bayani mai ruwa ko 0.1% sodium lauryl sulfonate aqueous bayani na 5 zuwa 6 days, kuma bushe a wani dangi zafi na 88%. Za a iya bushe membrane na polysulfone a dakin da zafin jiki tare da bayani na 10% glycerin, sulfonated man fetur, polyethylene glycol, da dai sauransu a matsayin wakili na dehydrating. Bugu da ƙari, surfactants kuma suna da tasiri mai kyau don kare pores na fim daga lalacewa.
Na biyu, ya kamata a kula da kiyayewa da kiyaye tsarin membrane mai hana ruwa da numfashi
Kulawa da kiyaye tsarin membrane ya kamata ya mayar da hankali kan batutuwa masu zuwa.
① Dangane da membranes daban-daban, ya kamata a biya kulawa ta musamman ga yanayin amfani, musamman ma yawan zafin jiki da ƙimar pH na kayan ruwa, har ma da abun ciki na chlorine a cikin ruwa na kayan.
② Lokacin da aka dakatar da tsarin membrane na ɗan gajeren lokaci, ya kamata a mai da hankali ga riƙe da danshi na membrane, saboda da zarar murfin membrane ya rasa ruwa, babu wani ma'auni na gyarawa, ruwa mai hana ruwa da numfashi zai ragu kuma ya lalace, wanda zai haifar da lalacewa. zai rage aikin membrane.
③Lokacin tsayawa, guje wa hulɗa da ruwa mai yawa.
④ Wanke da kula da membrane akai-akai tare da ruwa mai kulawa don rage gurɓataccen membrane.
⑤ A cikin amfani, yi aiki daidai da yanayin aiki wanda tsarin membrane zai iya jurewa don gujewa wuce gona da iri.
