Izihlungi zesirinji ze-PTFE: Izingxenye ezibucayi ezinhlelweni ze-Filtration ze-Laboration

Amathegi: I-PTFE-membrane-clander nylon-membrane Hlunga-0.22-Um Hlunga-membrane I-PVDF-membrane-chrep ulwelwesi lwe-pes-membrane isihlungi se-pvdf Hlunga-0.45-Um I-Ptfe-membrane I-membrane-flex-fle Isihlungi seMembrane Ptfe-syringe
Ensimini yokuhlunga kwelabhoratri, ukunemba kanye nokwethenjwa kubaluleke kakhulu. Abaphenyi kanye nososayensi basebenzisa amasistimu wokuhlunga ukususa ukungcola, izinhlayiya kanye nama-microorganisms kusuka kumasampula ukuqinisekisa imiphumela efanelekile futhi engaguquki ekuhlolweni kwawo. Isakhi esisodwa esiyisihluthulelo esidlala indima ebalulekile kule nqubo yi-PTFE (polytetrafluoroethylene) isihlungi sesirinji.

Izihlungi zesirinji ze-PTFEUbe yithuluzi elisemqoka endaweni yakwa-La ele ele ele eleatoratoration ngenxa yamakhono abo amahle okuhlunga nokuphikiswa kwamakhemikhali. I-PTFE iyi-fluoropolymer yokwenziwa eyaziwa ngezakhiwo zayo ezinhle kakhulu. Isakhiwo saso esiyingqayizivele sinama-athomu e-carbon ahlanganiswe ama-athomu ama-fluorine, adale impahla ezinzile futhi ezi-inert. Lezi zakhiwo zenza izihlungi zesirinji ze-PTFE zilungele izinhlelo ezahlukahlukene zezicelo, kubandakanya nokuhlaziywa ezimbonini zezemithi, ezemvelo, nasezimbonini zokudla.

Hlukana ungene endaweni eyi-0.45 micron ngokufunda i-athikili yethu ephelele. Vula ukubaluleka kwawo ezinhlelweni zokuhlunga kwelabhoratri kanye nomthelela wazo emiphumeleni eqondile nethembekile:Igayidi ephelele yokuhlunga okungu-0.45 micron: konke okudingeka ukwazi

Ukumelana Kwamakhemikhali


Izihlungi zesirinji ze-PTFE zibhekwa kakhulu ukumelana kwazo okuhle kwamakhemikhali. I-fluorine ne-carbon Bonding ye-PTFE kwakha izinzile ezizinzile, ezi-inert ezingamelana nokuchayeka ezinhlobonhlobo ze-solvents enamandla, ama-acid nezisekelo. Le mpahla iwusizo ikakhulukazi lapho ukuhlunga amasampula aqukethe izixazululo ze-organic, ama-acid anamandla, noma izixazululo ezilonakalisayo. Abaphenyi bangasebenzisa ngokuqinisekaIzihlungi zesirinji ze-PTFEKuzinhlelo zokusebenza lapho ezinye izinto zokuhlunga zitholakala ekuwohlokeni noma ekuvuthweni, kuqinisekisa ubuqotho besampula nokuvimbela ukungcoliswa.

Hydrophobic


Izakhiwo ze-hydrophobic ze-PTFE zingenye inzuzo enkulu yokuhlunga okurinji okwenziwe ngale ndaba. I-PTFE ingukuphindisela kwamanzi okungokwemvelo, ichitha amanzi futhi ivumela kuphela izixazululo ezingalungile ezizodlula. Le mpahla iwusizo ikakhulukazi lapho ukuhlungwa izixazululo zamanzi ezinamanzi aqukethe izixazululo ze-organic noma uwoyela. Izakhiwo ze-Hydrophobic ze-PTFE zivimbela isihlungi ukuthi zingagcwaliswa ngamanzi, ukuvumela izakhi ezidingekayo zihlungwa kahle futhi zithuthukise inqubo ye-filltration ephelele.

Ukugcinwa kwezinhlayiyana


Izihlungi zesirinji ze-PTFE zitholakala ezinhlotsheni ezahlukahlukene zePore, ngokuvamile kusuka ku-0.1 kuya ku-10 ama-microns. Lapho ukuhlunga amasampula ukususa izinhlayiya ezithile noma ama-microorganisms athile, kubalulekile ukuze ukwazi ukukhetha usayizi ofanele we-pore. Izihlungi ze-PTFE zigcina izinhlayiya ngokunembile nangokuphumelelayo zisuse ukungcola okuhlosiwe njengama-bacterium, udaba lokufaka phakathi, kanye nezinhlayiya zama-fungamu. Lesi sici sinciphisa ingozi yokungcoliswa kwesampula futhi siqinisekise imiphumela eqondile yokuhlaziya.

Amazinga aphansi okukhishwa


Ngesikhathi senqubo yokuhlunga, ezinyeokokuhlunga izintoKhipha ama-extractable angaphazamisa isampula futhi aguqule umhlaziyi onentshisekelo. Kodwa-ke, amazinga aphansi okukhishwa kwezihlungi zesirinji ze-PTFE azilwenza ikakhulukazi amasu wokuhlaziya abucayi kakhulu lapho ubumsulwa besampula bubaluleke kakhulu. Ama-extractable amancane ezihlungi ze-PTFE asiza ukugcina ubuqotho kanye nokwethenjwa kwemiphumela yokuhlaziya.

Vula izimfihlo zokukhetha isihlungi esiphawula esisezingeni eliphakeme esihlokweni sethu esinemininingwane. Thola izinto ezibalulekile okufanele ucabangele futhi wenze izinqumo ezinolwazi zezidingo zakho zokuhlunga:Ungasikhetha kanjani isihlungi esifanele sesirinji sokulungiswa kwesampula yakho?

Osayizi nokucushwa


Izihlungi zesirinji ze-PTFE zitholakala ngosayizi ezahlukahlukene kanye nokucushwa ukuze kuhlaliswe osayizi abahlukahlukene besirinji kanye namavolumu e-filltration. Lokhu kuguquguquka kuvumela abacwaningi ukuthi bakhethe isihlungi esilungele kahle izidingo zabo ezithile. Ngaphezu kwalokho, ezinye izihlungi zesirinji ze-PTFE ziza ngesendlalelo sangaphambi kokuhlunga, njenge-fiber fielbration noma i-polypropylene, ethuthukisa ukusebenza kwezihlunga ngokususa izinhlayiya ezinkulu. Lezi zinketho zinikeza abacwaningi ukusebenzisana okuhlukahlukene ukuze basebenzise inqubo yokuhlunga.

Ngokubheka nokusebenzisa lezi zinto ezibalulekile zeIzihlungi zesirinji ze-PTFE, abacwaningi nososayensi bangazihlanganisa ngokuzethemba ezinhlanganweni zabo zokuhlubula kwelabhoratri. Ukumelana kwamakhemikhali, i-hydrophobicity, ukugcinwa okunembile okuyizinhlayiyana, kanye namazinga aphansi okukhishwa kwezihlungi zesirinji zePTFE anikela ngemiphumela enembile nethembekile, ubuqotho obuthembekile, nentuthuko emikhakheni yesayensi.

Hlola umhlaba wezihlungi ze-micron ezingu-0.22 esihlokweni sethu esifundisayo. Thola Indima Yabo Ebalulekile Ezinhlelweni Zokuhlunga Zokusebenzisa I-Laboration kanye nomthelela wazo emiphumeleni enembile:Igayidi ephelele yokuhlunga okungu-0.22 micron: konke okudingeka ukwazi
