Yadda ake Zabar Tacewar Sirinji

Babban manufar filtar sirinji shine tace ruwa da kuma cire barbashi, sediments, microorganisms, da sauransu. Ana amfani da su sosai a fannin ilmin halitta, sunadarai, kimiyyar muhalli, magani, da magunguna.Wannan matattarar ta shahara sosai saboda kyakkyawan tasirin tacewa, dacewa da inganci.Koyaya, zabar tacewar sirinji mai kyau ba abu bane mai sauƙi kuma yana buƙatar fahimtar halaye na membranes daban-daban na tacewa da sauran abubuwan da ke da alaƙa.Wannan labarin zai bincika yadda ake amfani da matatun allura, halaye na kayan membrane daban-daban, da yadda ake yin zaɓin da ya dace.

• Girman ƙurar ƙurawar ƙorafin tacewa

1) Tace membrane tare da girman pore na 0.45 μm: ana amfani dashi don tace lokaci na wayar hannu na yau da kullun kuma yana iya saduwa da buƙatun chromatographic gabaɗaya.

2) Tace membrane tare da girman pore na 0.22μm: Yana iya cire ɓangarorin lafiya sosai a cikin samfuran samfura da matakan hannu da kuma cire ƙwayoyin cuta.

• Diamita na membrane tace

Gabaɗaya, yawancin diamita na matattarar tacewa sune Φ13μm da Φ25μm.Don samfurin samfurin 0-10ml, Φ13μm za a iya amfani da shi, kuma don samfurin samfurin 10-100ml, Φ25μm za a iya amfani dashi.

• Polyethersulfone (PES)

Features: Hydrophilic tace membrane yana da halaye na high kwarara kudi, low extractables, mai kyau ƙarfi, ba ya adsorb sunadaran da kuma ruwan 'ya'ya, kuma ba shi da wani gurbatawa ga samfurin.

Aikace-aikace: An tsara don nazarin halittu, gwaji, magunguna da tacewa bakararre.

• Mixed cellulose esters (MCE)

Features: Uniform pore size, high porosity, babu kafofin watsa labarai zubar, bakin ciki rubutu, low juriya, azumi tacewa gudun, kadan adsorption, low price da farashi, amma ba resistant zuwa Organic mafita da kuma karfi acid da alkali mafita.

Aikace-aikace: Tacewar hanyoyin maganin ruwa ko haifuwa na shirye-shiryen zafin zafi.

• Nailan membrane (Nylon)

Features: Good zafin jiki juriya, iya jure 121 ℃ cikakken tururi zafi matsa lamba haifuwa na 30 minutes, mai kyau sinadaran kwanciyar hankali, iya jure tsarma acid, tsarma alkali, alcohols, esters, mai, hydrocarbons, halogenated hydrocarbons da Organic hadawan abu da iskar shaka A iri-iri na Organic da inorganic. mahadi.

Aikace-aikace: Tacewar hanyoyin maganin ruwa da matakan wayar hannu.

• Polytetrafluoroethylene (PTFE)

Features: Mafi girman daidaituwar sinadarai, mai iya jure abubuwan kaushi na halitta kamar DMSO, THF, DMF, methylene chloride, chloroform, da sauransu.

Aikace-aikacen: Tacewar duk hanyoyin magance kwayoyin halitta da acid mai ƙarfi da tushe, musamman masu ƙarfi waɗanda sauran membranes tacewa ba za su iya jurewa ba.

• Polyvinylidene fluoride membrane (PVDF)

Siffofin: Membran yana da ƙarfin ƙarfin injiniya, kyakkyawan juriya na zafi da kwanciyar hankali na sinadarai, da ƙarancin adsorption na furotin;yana da karfi korau electrostatic Properties da hydrophobicity;amma ba zai iya jure wa acetone, dichloromethane, chloroform, DMSO, da dai sauransu ba.

Aikace-aikace: Hydrophobic PVDF membrane aka yafi amfani ga gas da tururi tacewa, da kuma high-zazzabi ruwa tacewa.Ana amfani da membrane na PVDF na hydrophilic don bakararre magani na kafofin watsa labarai na al'adun nama da mafita, yawan zafin jiki na ruwa, da sauransu.
