Indlela Yokukhetha Isihlungi Sesirinji

Inhloso eyinhloko yezihlungi zesirinji ukuhlunga uketshezi futhi kukhishwe izinhlayiya, izinhlayiya, ama-microorganisms, njll. Zisetshenziswa kakhulu ku-biology, chemistry, isayensi yezemvelo, imithi, kanye nemithi.Lesi sihlungi sithandwa kakhulu ngomphumela waso omuhle kakhulu wokuhlunga, ukunethezeka nokusebenza kahle.Kodwa-ke, ukukhetha isihlungi sesirinji esifanele akulula futhi kudinga ukuqonda izici zolwelwesi oluhlukahlukene lokuhlunga nezinye izici ezihlobene.Lesi sihloko sizohlola ukusetshenziswa kwezihlungi zenaliti, izici zezinto ezihlukahlukene ze-membrane, nendlela yokwenza ukukhetha okufanele.

• Usayizi wembotshana wolwelwesi lwesihlungi

1) Isihlungi se-membrane esinosayizi wembotshana ongu-0.45 μm: sisetshenziselwa isampula evamile yokuhlunga kwesigaba seselula futhi singahlangabezana nezidingo ezijwayelekile zechromatographic.

2) I-membrane yesihlungi enosayizi wembotshana ongu-0.22μm: Ingasusa izinhlayiya ezinhle kakhulu kumasampula nezigaba eziphathwayo kanye nokukhipha ama-microorganisms.

• Ububanzi be-membrane yesihlungi

Ngokuvamile, amadiamitha olwelwesi lwesihlungi asetshenziswa kakhulu ngu-Φ13μm no-Φ25μm.Ukuze uthole amavolumu esampula ka-0-10ml, u-Φ13μm angasetshenziswa, futhi kumavolumu esampula ka-10-100ml, u-Φ25μm angasetshenziswa.

• I-Polyethersulfone (PES)

Izici: I-membrane yesihlungi se-Hydrophilic inezici zokugeleza okuphezulu, okukhishwe okuphansi, amandla amahle, ayikhangisi amaprotheni neziqephu, futhi ayinakho ukungcola kusampula.

Izicelo: Idizayinelwe i-biochemistry, ukuhlolwa, ukuhlunga kwezemithi kanye nokuhlunga okubulalayo.

• I-Mixed cellulose esters (MCE)

Izici: Usayizi we-pore olinganayo, i-porosity ephezulu, akukho ukuchithwa kwemidiya, ukuthungwa okuncane, ukumelana okuphansi, isivinini sokuhlunga okusheshayo, i-adsorption encane, intengo ephansi nezindleko, kodwa ayimelani nezixazululo ze-organic kanye nezixazululo eziqinile ze-asidi ne-alkali.

Isicelo: Ukuhlunga kwezixazululo ezinamanzi noma ukuvalwa kokwenziwa kwezinto ezizwela ukushisa.

• Ulwelwesi lwenayiloni (Inayiloni)

Izici: Ukumelana okuhle kwezinga lokushisa, kungamelana no-121 ℃ ukuvala inzalo ye-steam esigcwele imizuzu engama-30, ukuzinza okuhle kwamakhemikhali, kungamelana nama-acids acwebileyo, i-alkali ehlanjululwe, i-alcohol, i-ester, uwoyela, ama-hydrocarbon, ama-halogenated hydrocarbon kanye ne-organic oxidation Izinhlobonhlobo ze-organic kanye ne-inorganic. izinhlanganisela.

Isicelo: Ukuhlunga izixazululo ezinamanzi kanye nezigaba zeselula eziphilayo.

• I-Polytetrafluoroethylene (PTFE)

Izici: Ukuhambisana kwamakhemikhali okubanzi kakhulu, okukwazi ukumelana nezinyibilikisi zemvelo ezifana ne-DMSO, THF, DMF, methylene chloride, chloroform, njll.

Isicelo: Ukuhlunga zonke izixazululo eziphilayo kanye nama-asidi aqinile nezisekelo, ikakhulukazi izincibilikisi ezinamandla ezinye izihlungi ezingakwazi ukubekezelela.

• I-Polyvinylidine fluoride membrane (PVDF)

Izici: I-membrane inamandla amakhulu emishini, ukumelana nokushisa okuhle nokuzinza kwamakhemikhali, kanye nezinga eliphansi le-protein adsorption;inezindawo ezinamandla ezimbi ze-electrostatic kanye ne-hydrophobicity;kodwa ayikwazi ukubekezelela i-acetone, i-dichloromethane, i-chloroform, i-DMSO, njll.

Isicelo: Ulwelwesi lwe-Hydrophobic PVDF lusetshenziswa kakhulu ukuhlunga igesi nesimusi, kanye nokuhlunga uketshezi olusezingeni eliphezulu.Ulwelwesi lwe-Hydrophilic PVDF lusetshenziswa kakhulu ekwelapheni okuyinyumba kwemidiya yesiko lezicubu nezisombululo, ukuhlunga uketshezi olushisa kakhulu, njll.
