Indlela yokukhetha isihluzo sesirinji

Eyona njongo yezihluzi zesirinji kukucoca ulwelo kunye nokususa amasuntswana, intlenga, iimicroorganisms, njl.njl. Zisetyenziswa kakhulu kwibhayoloji, ikhemistri, isayensi yokusingqongileyo, amayeza, kunye namayeza.Esi sihluzo sithandwa kakhulu ngenxa yesiphumo saso esihle sokuhluza, ukulunga kunye nokusebenza kakuhle.Nangona kunjalo, ukukhetha isihluzo esifanelekileyo sesirinji akukho lula kwaye kufuna ukuqonda iimpawu zeembrane ezahlukeneyo zokucoca kunye nezinye izinto ezinxulumeneyo.Eli nqaku liza kuphonononga ukusetyenziswa kwezihluzo zenaliti, iimpawu zemathiriyeli ye-membrane eyahlukeneyo, kunye nendlela yokwenza ukhetho olufanelekileyo.

• Ubungakanani be pore inwebu yokucoca

I-1) I-membrane yesihluzi esinobungakanani be-pore ye-0.45 μm: isetyenziselwa isampuli eqhelekileyo yokucoca isigaba seselula kwaye inokuhlangabezana neemfuno eziqhelekileyo zechromatographic.

2) I-membrane yokucoca kunye nobukhulu be-pore ye-0.22μm: Iyakwazi ukususa amasuntswana amahle kakhulu kwiisampuli kunye nezigaba ezihambahambayo kunye nokususa i-microorganisms.

• Ububanzi be-membrane yokucoca

Ngokuqhelekileyo, i-diameter ye-membrane yokucoca esetyenziswa ngokuqhelekileyo yi-Φ13μm kunye ne-Φ25μm.Kwimiqulu yesampula ye-0-10ml, i-Φ13μm ingasetyenziswa, kunye nemilinganiselo yesampuli ye-10-100ml, i-Φ25μm ingasetyenziswa.

• I-Polyethersulfone (PES)

Iimpawu: I-membrane yokucoca i-Hydrophilic ineempawu zesantya esiphezulu sokuhamba, i-extractables ephantsi, amandla alungileyo, ayibhengezi iiprotheni kunye nezicatshulwa, kwaye ayinakho ukungcola kwisampuli.

Izicelo: Yenzelwe i-biochemistry, uvavanyo, ukuhluza amayeza kunye neentsholongwane.

• I-Mixed cellulose esters (MCE)

Iimpawu: Ubungakanani obufanayo be-pore, i-porosity ephezulu, akukho ukuchithwa kweendaba, ukuthungwa okuncinci, ukuchasana okuphantsi, isantya sokuhluza ngokukhawuleza, i-adsorption encinci, ixabiso eliphantsi kunye neendleko, kodwa azichasananga nezisombululo ze-organic kunye ne-asidi eqinile kunye nezisombululo ze-alkali.

Isicelo: Ukuhluzwa kwezinyibiliko ezinamanzi okanye ukuvala inzalo yamalungiselelo angavani nobushushu.

• Inwebu yenayiloni (Nayiloni)

Iimpawu: Ukumelana nobushushu obulungileyo, kunokumelana ne-121 ℃ i-saturated steam eshushu yoxinzelelo lwe-sterilization yemizuzu engama-30, uzinzo oluhle lweekhemikhali, inokumelana ne-acids dilute, dilute alkali, alcohols, esters, oils, hydrocarbons, halogenated hydrocarbons kunye ne-organic oxidation. iikhompawundi.

Isicelo: Ukuhluzwa kwezisombululo ezinamanzi kunye nezigaba ze-organic mobile.

• I-Polytetrafluoroethylene (PTFE)

Iimpawu: Ukuhambelana kweekhemikhali ezibanzi, ezikwaziyo ukumelana ne-solvents eziphilayo ezifana ne-DMSO, THF, i-DMF, i-methylene chloride, i-chloroform, njl.

Isicelo: Ukuhluzwa kwazo zonke izisombululo ze-organic kunye ne-acids ezomeleleyo kunye neziseko, ngokukodwa ii-solvents ezinamandla ezinokuthi ezinye iimbumba zokucoca azikwazi ukunyamezela.

• I-Polyvinylidine fluoride inwebu (PVDF)

Iimpawu: I-membrane inamandla amakhulu omatshini, ukumelana nobushushu obuhle kunye nokuzinza kweekhemikhali, kunye nesantya esiphantsi seprotheyini ye-adsorption;ineepropati ezinamandla ezimbi ze-electrostatic kunye ne-hydrophobicity;kodwa ayikwazi ukunyamezela i-acetone, i-dichloromethane, i-chloroform, i-DMSO, njl.

Isicelo: I-Hydrophobic PVDF inwebu isetyenziselwa ukuhluzwa kwegesi kunye nomphunga, kunye nobushushu obuphezulu bokucoca ulwelo.I-Hydrophilic PVDF inwebu isetyenziswa ikakhulu kunyango oluyinyumba lwemidiya yenkcubeko yethishu kunye nezisombululo, ukuhluzwa kolwelo olunobushushu obuphezulu, njl.
