Izihlungi zesirinji zivame ukusetshenziselwa ukususa izinhlayiya kusuka kusampula yoketshezi ngaphambi kohlobo oluthile lokuhlaziywa ukugwema ukulimala kwemishini

Izinhlobo ezimbili eziphambili zokuhlunga yilezo lapho ungathola khona isampula noma cha. Iningi lezihlungi zesirinji ezisetshenzisiwe azikuvumeli ukuthi ubuyise okuqinile. Zivame ukusetshenziswa ngaphambi kokuhlaziywa ukuze zisuse noma yikuphi okuqinile, okungaxazululiwe, okubonakalayo. OLUNYE, I-Hilter Holder (In-line) izinhlobo ikuvumela ukuthi uphinde uthole isihlungi sakho.

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

Ukuhlanza isihlungi sesirinji

Beka phansi

Lapho uhlanzaisihlungi sesirinji, amanzi ancishisiwe athulwa okokuqala nge-tube yenaliti, elandelwa yi-ultrasonic cishe imizuzu engama-20, bese efakwe emanzini ancishisiwe isikhathi esingaphezu kwamahora ayi-5, asuswe futhi omiswe ngamadigri angama-40. Musa ukubhaka ama-gaskets, vele ubayeke bome ngokwemvelo.

Ukuhlanza kanye nokubulala amagciwane kwesikhiyiso se-microrift sesirinji ngemuva kokusebenzisa okufanayo nakwamanye amapulasitiki aphezulu, kepha i-polyethylene ayikwazi ukubacindezela kakhulu.

A. Amanzi agezwa amahlandla ayishumi nawomile. Siphinde sisebenzise i-gasket ukuze somiswa. Ukuqothuka kunomthelela omncane. Ngokuvamile, setha izinga lokushisa le-oven livame ukusethwa ngamadigri angama-56 ngoba i-Edat ivame ukudingeka ukuchithwa;

Ukuhlanza kanye nokubulala amagciwane kokuhlunga kwesirikhi kweMicron ngemuva kokusetshenziswa kuyafana nalokho kwamanye amapulasitiki aphezulu

B. Cwilisa ku-1% i-hydrochloric acid ifakwe emanzini ubusuku (ngaphansi kwe-6h);

C. Amanzi ahlanzwa kaningi amahlandla ayi-10 bese amanzi ahlanekezelwe agezwa kabili, khona-ke ulwelwesi lokuhlunga lungafakwa ngaphansi kwengcindezi ephezulu noma yomile ukuze isetshenziswe kahle.

Ukubulala amagciwane isihlungi sesirinji

Beka phansi

Musa ukucwilisa isihlungi se-syrinji ku-acid uketshezi, ubilise imizuzu engama-20 noma ufake i-cap kuNaoh amahora angama-6 ukuya kwa-12. Faka ezimbiliHlunga uMevbranesngaphambi kokupakisha. Sidinga ukunaka i-membrane phezulu noma phansi futhi siqinisekise ukuthi kukhulunywa lapho ulwelwesi lokuhlunga lufakiwe. Silengele kancane isikulufa, sibeke ebhokisini le-aluminium, inzalo ngamakhilogremu ayi-15 imizuzu engama-30 kumpheki wengcindezi, bese uyimisa ukuze isetshenziswe kamuva. Sicela wazi ukuthi, lapho uyikhipha, qinisa isikulufa ngokushesha.

Cwilisa ulwelwesi lokuhlunga ngamanzi amathathu antshontshiwe okungenani ngengxenye yehora ngokucindezela okukhulu. Ngaphezu kwalokho, ungaqinisekisi isirinji yelebhu lapho ufaka. Ulwelwelwesi lunezinhlangothi zombili, ubuso obushelelezi phansi, futhi ubuso obunzima babheke phezulu ukuze izihlungi zizokonga umzamo. Kuhle ukusetshenziswa ngokushesha ngemuva kwengcindezi ephezulu. Ulwelwesi lokuhlunga luhle ungafuni ingcindezi ephezulu yesibili.

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

Ukwakheka kwe-fingermbane yokuhlunga

Ulwelwesi lokuhlunga luvame ukubeka izingqimba ezimbili. Ulwelwesi olungaphezulu lwalungu-micron ongu-0,4, ongezansi kwakungu-0.22 micron, kanti lezi zingqimba ezimbili zazingu-0.22 micron. Beka i-PTFE Syringe Hlunga izihlungi ze-PES ngemuva kokufaka imizuzu engu-10 ~ 20. Ngemuva kokuthi igcwele phama, bopha izihlungi zesirinji ngendwangu bese uzinzisa. Qaphela ukuthi ulwelwesi kufanele lube nge-perpendicular emhlabathini ukuze lingaphule ngisho nokucindezela okukhulu. Isihlungi esisezingeni elisezenzakalelayo kufanele sifakwe emanzini ancishisiwe isikhathi esingaphezu kwamahora amathathu noma ubusuku bese sibekwe esikrinini sokuhlunga esiyisirinji, ubuso obushelelezi phezulu. Lapho ujikisa izihlungi zesirinji, ungavele usonteke e-Airtight.

Uma ungakwazi ukuqinisa isihlungi se-syrinji, phakamisa ukushintshwa kwe-vent bese ugoqa ukuphuma ngephepha le-sulfate. Songa i-strainer ephepheni le-kraft. Izihlungi zesirinji kufanele ziqiniswe lapho zisebenzisa, kepha amandla kufanele asetshenziswe ngokulinganayo. Cwilisa nge-dilute hydrochloric acid isikhathi esingangehora.

Ngemuva kokuthi amanzi ompompi ahlanjululwe, cwilisa emanzini anomugqa ophindwe kabili ubusuku bonke. Ngemuva kokumiswa, thambisa ulwelwelwesi lwe-syringe face ubuso phezulu, bese ulinamathisela futhi ujijeke ngamanzi anomusi aphindwe kabili, kepha ungaqinisi ukuqina. Landa, bese yomile, futhi ukulungele ukusetshenziswa. Qaphela ukuthi uma isihlungi se-syringe singasetshenziswanga ngasikhathi sinye, ungasihlukanisi kabili ukuvikela ulwelwesi lokuhlunga kusuka ekuphuleni.
