Pankhani yowonetsetsa kuti kukhulupirika ndi kudalirika kwa zotsatira zowunikira m'makonzedwe a labotale, kusankha kwaeeya f fyulutandizovuta. Zipangizo zosiyanasiyana zimawonetsa zokhudzana ndi zokhudzana ndi tinthu, zomwe zimatha kupangitsa kuti zitsanzo zomwe zakonzedweratu, makamaka mu maluso monga ma chpomatography a chromatography (hplc).

Mafunso omwe amafunsidwa pafupipafupi za syring zosefera, onetsetsani kuti onani nkhani yodziwitsa iyi:Mutu wa "syvinge sfaw" 50 nthawi zambiri mafunso

Zinthu zazikulu zomwe zimapangitsa kuti tinthu osungitsa a tinthu

1. Kukula kwa Pore

Kukula kwa chophimba kwa syrenge ndi imodzi mwazinthu zofunika kwambiri zomwe zikukhudza luso lake la posungira. Mitundu yodziwika bwino ikuphatikiza:

0.22 μm eyinya Zosempha: Zosefera izi ndi zabwino pakugwiritsa ntchito zofunika kuchotsedwa kwa mabakiteriya komanso tinthu tating'ono. Amagwiritsidwa ntchito nthawi zambiri mu kuphatikiza njira komanso kusefa chikhalidwe cha foni. Chifukwa cha kukula kwawo kokongola, amapereka gawo lalikulu la tinthu, nthawi zambiri zopitilira 98% za tinthu tating'ono kuposa 0.22 μm.

0.45 μm eyinya Zosempha: Zosefera izi ndizoyenera pochotsa tinthu tating'onoting'ono, zimapangitsa kuti akhale chinthu chotchuka pakukonzekera kwa HPLC zitsanzo. Pomwe amalola kuti pakhale mitengo yofulumira poyerekeza ndi zosefera za 0.26.22, zimatha kusunga tinthu tating'onoting'ono, nthawi zambiri zimakhala pafupifupi 90-95% ya tinthu tating'onoting'ono kuposa 0.45 μm.

Kusankha kukula koyenera kumafuna kuwerengera kofananira ndikuwotcha. Zingwe zazing'ono zolumikizira zimapereka kusungidwa kwambiri koma zimatha kuchepetsa njira yofinya.

Ndikufuna kudziwa chidziwitso chonse cha Synge Svie Syvinge, chonde onani nkhaniyi:Kuwongolera kwathunthu kwa SYHRE Zosefera: Zosankhidwa, kusankha, mtengo, ndi kugwiritsa ntchito

2. Zosefera

Zinthu za syvinge fyululu zimachitanso mbali yofunika posankha momwe tinthu tagwiritsidwira ntchito. Nazi zina mwazinthu wamba zomwe zimagwiritsidwa ntchito mu syring zosefera:

Polytetraflofentlene (PTF): kudziwika chifukwa cha kukana kwa mankhwala.Ptche eyinya zosemphandioyenera masitima ankhanza komanso mapulogalamu apamwamba kwambiri. Nthawi zambiri amawonetsa kuchuluka kwa tinthu tating'onoting'ono, nthawi zambiri amakhala pafupifupi 98-100% ya tinthu tating'onoting'ono kuposa 0,45 μm, ndikuwapangitsa kukhala abwino pakugwiritsa ntchito HPLC.

Nylon: Nylon eyinya zosemphandiosintha ndipo itha kugwiritsidwa ntchito kwa onse osungunuka komanso okhazikika. Amawonetsa kuti tibungwe tinthu tating'onoting'ono koma timatha kukhala ndi luso lotsika poyerekeza ndi zosefera za PTFE, makamaka m'malo azovuta zamankhwala.

Polltasulfone (Pes): Ziweto eyinya zosemphaamadziwika chifukwa cha mapuloteni omangamanga, ndikuwapangitsa kukhala oyenera kufupikira kwachilengedwe. Amapereka timitengo yabwino ya tinthu tating'onoting'ono, pafupifupi 95-98% kwa zosefera za 0.22 μm.

Cellulose yosinthidwa (RC): RC Syring Zosefera nthawi zambiri imagwiritsidwa ntchito pamankhwala am'madzi ndikupereka luso lokwanira la tinthu. Komabe, kafukufuku wasonyeza kuti zosefera za RC zitha kukhala ndi mitengo yotsika, nthawi zina yotsika ngati 48% ya 4,45 μm, kutanthauza kuti ndi gawo lalikulu la tinthu tating'onoting'ono.

ESTERS yosiyanasiyana ya cellulose (MCE):Mc eyinya zosempha ali oyenera kwambiri komanso oyenera mayankho am'madzi. Amagwiritsidwa ntchito kawirikawiri mu micheruological amasanthula chifukwa chosunga bwino kwambiri kwa tizilombo, koma kuchita bwino kwawo kumatha kusiyanasiyana malinga ndi pulogalamu inayake.

Dongosolo la syleng fyuluta imathanso kukopa mphamvu yake yosungitsa. Zosefera zazikulu zimatha kukhala ndi zomwe zimatulutsa, kulola kuti pakhale kuchuluka kwa mafinya, koma amathanso kukhala ndi kufalitsa kwina kwa kukula kwa pores, kumakhudzanso ntchito yonse. Kuphatikiza apo, kapangidwe ka fyuluta, monga kupezeka kwa zosefera isanakwane kapena njira zapamwamba, zimatha kukulitsa vuto la tinthu.

Kuyerekezera tinthu tating'onoting'ono tomwe timagwiritsa ntchito zofananira zosiyanasiyana za syring

Kutengera ndi zomwe takambirana, mwachidule mwachidule ya kuchuluka kwa tinthu tating'onoting'ono kosiyanasiyana kwa zida zofananira:

Zosefera	Kukula Kwa Pore	Zoyenera kugwiritsa ntchito bwino	Ntchito Zabwino Kwambiri
Ptche	0.45 μm	98-100%	Steidents Studdent, HPLC
Nylon	0.45 μm	90-95%	Kugwiritsa Ntchito Kwambiri, Madzi ndi Organic
Ziweto	0.22 μm	95-98%	Zitsanzo za zitsanzo, mapuloteni otsika
Cellulose yosinthidwa	0.45 μm	48-50%	Mankhwala am'madzi, kusanthula kwamakhalidwe
Ma Elelil Ests	0.45 μm	Mitundu yosiyanasiyana	Kusanthula Kusanthula

Mapeto

Kusankha zosefera zolondola zosefera ndikofunikira kuti muwonetsetse kuchuluka kwakukulu kwa gawo losunga kwa tinthu tazokha pamalonda, makamaka kusanthula kwa HPLC. Zosefera za PTF Mosiyana ndi zimenezo, zosefera zam'manja sizingapereke mwayi wosunga zokwanira kugwiritsa ntchito zinthu zina, kunyalanyaza kunyalanyaza deta.

Mukamasankha sy fluquese, lingalirani zofunikira mwatsatanetsatane za kusanthula kwanu, kuphatikizapo mtundu wake, zosungunulira, ndipo mukufuna kugwiritsa ntchito bwino ntchito. Mwa kumvetsetsa kusiyana kwa tinthu osungirako zinthu zosiyanasiyana zosefera zosefera, mutha kupanga chisankho chidziwitso chomwe chimasintha bwino komanso kudalirika kwa zotsatira zanu. Kusaka koyenera sikungoteteza chida chanu, komanso chimathandizira kuti muchite bwino pa ntchito zanu zapantchito.

Kodi mukudziwa ngati fayilo ya syngenge ikhoza kugwiritsidwanso ntchito? Chonde onani nkhaniyi: Kwa syring zosefera, mudzagwiritse ntchito?
