I-Polyvinylidene Fluoride (PVDF)Futhi i-nylon iyizinto ezimbili ezahlukene ezisetshenziswa kakhulu ekuhlunga kwesirinji kwezicelo ezahlukahlukene zelebhu. Ukuzikhethela phakathi kwe-PVDF ne-nylon kuncike kwizidingo ezithile zenqubo yokuhlunga. Kunezici eziningana okufanele zicatshangelwe lapho zinquma phakathi kokuhlunga kwesirinji noma kwe-nylon

Ukufaneleka kwamakhemikhali

I-PVDF (Polyvinylidene Fluoride):

I-PVDF yaziwa ngokumelana kwayo okuhle kwamakhemikhali, okwenza kube lula ukuthola ama-solvents amaningi namakhemikhali.

Ngokuvamile kukhethwa izicelo ezibandakanya izixazululo ezinolaka kanye nezinto eziphilayo.

Izihlungi zesirinji ze-PVDFIyakwazi ukumelana nokuchayeka kumakhemikhali ahlukahlukene ngaphandle kokuwohloka.

Nylon:

I-Nylon iyahambisana namakhemikhali ngezinto eziningi, kepha kungenzeka ingamelana ne-solvents ethile njenge-PVDF.

Izihlungi zesirinji zeNylon zivame ukulungele ukugcwala kwezixazululo zamanzi namakhemikhali anolaka.

Hlola imininingwane ejulile ngo-0.45 fidters kule ndatshana, ukuqondise ngokukhethekile ukukusiza wenze izinqumo ezinolwazi zezidingo zakho zokuhlunga:Igayidi ephelele yokuhlunga okungu-0.45 micron: konke okudingeka ukwazi

Hydrophilicity \ hydrophophobicity

I-PVDF: I-PVDF i-hydrophopobic ebonakalayo

I-PVDF i-hydrophopobic ebonakalayo futhi ixosha amanzi.

Le mpahla yenza izihlungi zesirinji ze-PVDF zilungele ukugcwala kwezixazululo ezingezona ezenzayo namasampula anokuqukethwe kwamanzi okuphansi.

Nylon:

I-nylon ngokujwayelekile i-hydrophilic futhi ibonisa ubudlelwane emanzini.

Izihlungi zesirinji zeNylon zisebenza ngokuhlunga kwezixazululo zamanzi namasampula anokuqukethwe kwamanzi okuphezulu.

Amaprotheni abophayo

PVDF:

Izihlungi zesirinji ze-PVDFkunconywa lapho amaprotheni aphansi aqakathekile.

Imvamisa isetshenziswa kuzinhlelo zokusebenza lapho ukululama kwamaprotheni kuyinto ebaluleke kakhulu, efana namasampula endalo noma we-biochemical.

Nylon:

Izihlungi zesirinji ze-nylon zingabonisa ubukhulu bezinto eziphakeme ezibophayo uma kuqhathaniswa ne-PVDF.

I-PVDF ingaba ukukhetha okungcono kwezicelo lapho kubalulekile khona amaprotheni ama-adsorpr asemncane.

Ukuze uthole ukucwila okujulile ekuhlunga okuyisirinji, hlola le ndatshana ukuze iphelele ngokuphelele. Umhlahlandlela wakho wokugcina wokuqonda ukusetshenziswa nokucatshangelwa lapho ukhetha izihlungi zesirinji:Umhlahlandlela ophelele wokuhlunga kwesirinji: Izici, Ukukhetha, Intengo, kanye nokusebenzisa

Ukumelana Nezinga lokushisa

I-PVDF: I-PVDF inokumelana nokushisa okuhle kakhulu

I-PVDF ilungele kahle izinqubo zokuhlunga emazingeni okushisa aphezulu ngenxa yokumelana kwayo okuhle kakhulu.

Ingamelana namazinga okushisa ahlukahlukene ngaphandle kokuyekethisa ubuqotho bezinhlelo.

Nylon:

Izihlungi zesirinji zeNylon nazo zinokumelana kahle nokushisa okuhle kakhulu, kepha kungenzeka zingafaneleki njenge-PVDF yezicelo emazingeni okushisa aphezulu.

Ukuhambisana namasu wokuhlaziya

PVDF:

Izihlungi zesirinji ze-PVDFzivame ukusetshenziswa kumasu wokuhlaziya afana ne-HPLC.

Bakhethwa ngenxa yamazinga abo aphansi okukhishwa kanye nokuhambisana okubanzi nezinhlobonhlobo zezindlela zokuhlaziya.

Nylon:

Izihlungi zesirinji zeNylon zilungele izinhloso zokuhlunga okujwayelekile.

Kungenzeka kube yisinqumo esihle kakhulu sokuthola amasu athile wokuhlaziya adinga amazinga we-Ultra-aphansi aphansi, kepha asasetshenziswa kabanzi ekuhlutjweni kwelebhu ejwayelekile.

4 Isizathu sokukhetha i-PVDF

Ukuvumelana kwamakhemikhali:Izihlungi ze-PVDF (Polyvinylidene Fluoride) zinikeza ukumelana okuhlukile kwamakhemikhali ahlukahlukene, kufaka phakathi ama-acid, izisekelo, kanye nezinto eziphilayo, ukuqinisekisa ukuhambisana namasampula ahlukahlukene kanye nezinhlelo zelebhu.

Ukumsulwa okuphezulu:Izihlungi ze-PVDF zaziwa ngezakhiwo zazo eziphansi zamaprotheni, zizenza zilungele izinhlelo zokusebenza lapho ubumsulwa besampula bubaluleke kakhulu, njengokuhlaziywa kwamaprotheni, ucwaningo lwemithi, ne-biotechnology.

Ukuqina okushisayo: Izihlungi ze-PVDFKhombisa ukuzinza okuhle kakhulu, ukugcina ubuqotho babo kanye nokusebenza ngobubanzi bokushisa okubanzi. Lokhu kubenza balungele izinhlelo zokusebenza ezidinga inzalo noma ukuqinisa i-autoclaving, baqinisekise imiphumela ethembekile ngisho nangaphansi kwezimo ezimbi kakhulu.

Amandla okwenziwa ngomshini:Izihlungi ze-PVDF ziqinile ngokwemvelo futhi zihlala isikhathi eside, zinamandla aphezulu ashubile kanye nokumelana nokudwengula. Lokhu kubenza balungele ukugcwala kwezixazululo ezinolaka noma amasampula ahlanganisiwe ngaphandle kwengozi yokuhlunga noma ukwehluleka, ukuqinisekisa izinqubo zokuhlunga ezisebenzayo nezingaguquki.

Ngokufingqa, ukukhetha phakathi kwe-PVDF futhiIzihlungi zesirinji zeNylonKuya ngezidingo ezithile zenqubo yokuhlunga, kufaka phakathi uhlobo lwesampula, ukuba khona kwama-solvents, isidingo sokululama amaprotheni, kanye nokuhambisana nenqubo yokuhlaziya. Ngokusebenza kahle kwe-fieltration, ngaso sonke isikhathi Bheka izincomo zomenzi bese ubheka izakhiwo ezihlukile zento ngayinye.
