Emhlabeni wokuhlunga kwelabhoratri, izihlungi zesirinji kanye nezihlungi ze-membrane zingamathuluzi amabili ajwayelekile adlala indima ebalulekile ekulungiseni amasampula. Ngenkathi zingabonakala zifana ekuqaleni, zinezici ezihlukile, izinhlelo zokusebenza, kanye nezindlela zokusebenza. Le ndatshana ithatha ukujula okujulile ngohlu olusemqoka phakathi kokuhlunga ngezimpawu nokuhlunga okungama-membrane ukusiza abacwaningi kanye nochwepheshe welebhu benze isinqumo esinolwazi ngokususelwa kwizidingo zabo ezithile.

Imibuzo ebuzwa njalo mayelana nokuhlunga ngezimpawu, qiniseka ukuthi ubheka le ndatshana efundisayo:Isihloko se- "Syringe Filter" Imibuzo Ebuzwa Njalo Kaningi

Ukuqonda izihlungi zesirinji

Izihlungi zesirinji amadivaysi amancane, alahlekayo asetshenziselwa ukususa udaba lwamanzi avela kumasampula e-liquid ngaphambi kokuhlaziywa. Ziqukethe ulwelwesi lokuhlunga olugcinwe ezindlini zepulasitiki ezixhumeka kwisiprofetho esikhiyiwe. Lapho umsebenzisi esunduza i-plunger yesirinji, isampula liphoqelelwa ngolwelwesi lokuhlunga, okuholela kuketshezi olucacile olungaqoqwa ngendlela ye-vial noma esinye isitsha.

Izici ezibalulekile zokuhlunga kwesirinji:

Usayizi nokungabina: Izihlungi zesirinji zihlangene futhi kulula ukuzisingatha, zibenze balungele ukuhlunga amavolumu amancane we-liquid (ngokuvamile afinyelela ku-60 ml).

Izinhlobonhlobo zezinto zokulwa nolwelwesi: Izihlungi zesirinji ziza nezinto ezahlukahlukene ze-membrane ezinjenge-nylon, PTFE (polytetrafluoroethylene), PES (polyethersulfone), ne-PVDF (Polyvinylidene Fluoride). Indwangu ngayinye inezakhiwo ezihlukile ezenza zilungele izinhlelo ezithile.

Izinketho zosayizi we-Pore Ukukhethwa kosayizi we-pore kuncike kuhlobo lwezinhlayiya ezizohlungwa.

Ukusebenza kwezindleko: Ngokuvamile, izihlungi zesirinji zinobuqili ngokwengeziwe kunezinhlelo ezinkulu zokuhlunga, zibenza badume phakathi kwezindawo zokusebenzela ezinezingqinamba zesabelomali.

Ngabe ufuna ukwazi imininingwane ephelele yokuthi ungasikhetha kanjani isihlungi esifanele sesirinji, sicela uhlole le ndatshana: Ungasikhetha kanjani isihlungi esifanele sesirinji sokulungiswa kwesampula yakho?

Ukuqonda uMembrane izihlungi

Izihlungi zeMembrane nazo zisetshenziselwa ukuhlunga okuwuketshezi kepha ziyehluka kakhulu ekwakhiweni nasekusetshenzisweni. Lezi zihlungi ziqukethe ifilimu elincanyana noma ulwelwesi oluvumela izinhlayiya ezithile ukuthi zidlule ngenkathi zivimba abanye ngokuya ngosayizi noma amakhemikhali. Izihlungi zeMembrane zingasetshenziswa ekucushweni okuhlukahlukene, kufaka phakathi ukusetha kwe-vacuum fieltration noma njengengxenye yezinhlelo ezinkulu ze-FILTRATION.

Izici ezibalulekile zokuhlunga kwe-membrane:

Amasayizi amakhulu: Izihlungi zeMembrane zingangena ngamadayimane amakhulu, zibenze balungele ukuhlunga amavolumu amakhulu e-liquid.

Izicelo ezahlukahlukene: zivame ukusetshenziswa kuzinhlelo zokusebenza ezidinga ukuphenduka okuphezulu noma lapho amavolumu amakhulu adinga ukucutshungulwa khona, njengokuqapha imvelo noma ukukhiqizwa kwemithi.

Izinhlobo ezahlukahlukene zokuhlunga

Ufuna ukwazi ulwazi oluphelele mayelana nesihlungi se-syrinji, sicela uhlole le ndatshana:Umhlahlandlela ophelele wokuhlunga kwesirinji: Izici, Ukukhetha, Intengo, kanye nokusebenzisa

Umehluko Osemqoka phakathi kokuhlunga kwesirinji kanye nezihlungi ze-membrane

1. Indlela yeFiltration

Umehluko obaluleke kakhulu ulele ekutheni isihlungi ngasinye sisebenza kanjani:

Izihlungi zesirinji: Isampula licindezelwa ngesandla ngokusebenzisa isihlungi usebenzisa isirinji. Le ndlela iqondile futhi ilungele izinhlelo zokusebenza ezincane.

Izihlungi zeMembrane: Lokhu kungasebenza ngaphansi kwezimo ezahlukahlukene-vacuum tress, amandla adonsela phansi, noma izinhlelo eziqhutshwa yingcindezi - ezivumela ukuguquguquka okwengeziwe ekucutshungulweni kwamanani amakhulu.

2. Isampula umthamo wevolumu

Izihlungi zesirinjizivame ukukhawulelwa kumavolumu amancane wesampula (aze afike ku-60 mL), okwenza babe nelungele izivivinyo ngazinye noma amabhendi amancane. Ngokuphambene, izihlungi ze-membrane zikwazi ukuphatha amavolumu amakhulu kakhulu, azuzisa izinhlelo zokusebenza ezingenamkhawulo.

3. Ukusebenziseka kalula

Izihlungi zesirinji ngokuvamile kulula ukuzisebenzisa ngenxa yomklamo wazo oqondile. Abasebenzisi bamane banamathisele isihlungi esiyisirinji bese ucindezela isampula ngokusebenzisa. Ukuhlunga kukaMembrane kungadinga ukusetha okuyinkimbinkimbi okubandakanya amaphampu we-vacuum noma amasistimu wokucindezela, ongakwenza ekusebenzeni kwawo.

4. Ukucatshangelwa Kwezindleko

Izihlungi zesirinji zivame ukuba kubize kakhulu ukusebenza kwemisebenzi emincane ngenxa yemvelo yazo elahlekile kanye nephuzu lentengo eliphansi. Izihlungi zeMembrane zingafaka izindleko eziphakeme zokuqala kepha zingaba ezomnotho ezengeziwe emisebenzini emikhulu lapho zinciphisa imfucuza futhi zithuthukise khona.

5. Ukusebenza kahle kwe-FILTRATION

Ngenkathi zombili izinhlobo zokuhlunga zinikeza ukukhishwa okusebenzayo kwezinhlayiya, ukusebenza kwazo kungahluka ngokuya ngesicelo:

Izihlungi zesirinji: Ngokuvamile zisebenza ngokususa izinhlayiya ezivela kumavolumu amancane kepha kungenzeka kushaye ngokushesha ngamasampula angcoliswe kakhulu.

Izihlungi zeMembrane: zenzelwe amanani aphezulu okugeleza kanye namanani amakhulu; Imvamisa banamakhono angcono okuphatha ama-stricking ngaphambi kokuba kwenzeke ukuvalwa.

Ukukhetha isihlungi esifanele

Ukukhetha phakathi kokuhlunga kwesirinji kanye nezihlungi ze-membrane kuncike ezicini eziningana:

IVampula yesampula: Amasampula amancane (1-60 ml), izihlungi zesirinji zilungile; Ngemiqulu emikhulu, cabanga izihlungi ze-membrane.

Indlela ye-FILTRATION: Uma udinga ukulawula okwenziwa ngesandla ngaphezulu kwenqubo yokuhlunga, khetha izihlungi zesiko; Uma udinga ukucubungula okuzenzakalelayo noma okubucayi okuphezulu, khetha izihlungi ze-membrane.

Ukusebenza kwezindleko: Hlaziya isabelomali sakho kanye nemvamisa yokusebenzisa; Izihlungi zesirinji zivame ukushibhile ngokusetshenziswa ngezikhathi ezithile ngenkathi izihlungi ze-membrane zingagcina izindleko ezimweni zokucubungula eziningi.

Ukucaciswa kwesicelo: Cabanga ukuhambisana kwamakhemikhali kwento yokuhlunga namasampula akho; Qinisekisa ukuthi ukhetha isihlungi esihlangabezana nezidingo zakho ezithile zokuhlaziya.

Ukugcina

Ngokufigqiwe,Izihlungi zesirinjiFuthi izihlungi ze-membrane zombili zidlala indima ebalulekile ezinqubweni zokuhlunga zelebhu, kepha zingahlangabezana nezidingo ezihlukile ngokuya ngevolumu yesampula, ukusetshenziswa kalula, ukucatshangelwa kwezindleko, kanye nendlela yokusebenza. Ngokuqonda lokhu kuhluke kakhulu, abacwaningi bangenza izinqumo ezinolwazi zokwandisa ukugeleza kwabo futhi bathuthukise imiphumela yokuhlaziya. Noma ngabe ukhetha isihlungi se-syrinji ukuze usebenze kalula noma isihlungi se-membrane ukuze uthole amandla amaningi futhi ukuguquguquka okusebenzayo kuzoncika kwizidingo zakho zohlelo lokusebenza kanye nokusetha kwelebhu.

Uzosebenzisa kabusha lezi zihlungi zesirinji, uyazi yini ukuthi ingabe isihlungi se-syrinji esingasetshenziswa kabusha? Sicela ubheke le ndatshana: Okokuhlunga ngezimpawu, uzophinda usebenzise?
