dikarolwana tsa colloid tse qhalakaneng di ka arohana ka hara centrifuge

Na Likaroloana tsa Colloid tse Hasaneng li ka Arohana ka Sekhomaretsing?

Selelekela:

Li-colloid ke mofuta o ikhethang oa taba moo likaroloana li hasanngoang ka ho lekana ho pholletsa le seaplane, ho etsa motsoako o tsitsitseng. Mehlala ea li-colloid e kenyelletsa gelatin, lebese le tranelate e shapuoeng. Ho arola likaroloana tsa colloid tse hasantsoeng ho seaplane ho ka ba thata ka lebaka la boholo ba tsona bo bonyenyane le kabo e lekanang. Sehloohong sena, re hlahloba hore na centrifugation e ka arola likaroloana tsa colloid tse hasantsoeng ka katleho 'me re buisana ka mefokolo ea eona le ts'ebeliso e ka bang teng.

Ho Utloisisa Likaroloana tsa Colloid:

Dikaroloana tsa Colloid di fapana ka boholo ho tloha ho di-nanometer ho isa ho di-micrometer. Di teng boemong bo hasaneng, di boloka tekano e tsitsitseng ka lebaka la matla a kgahlehang le a nyonyehang a sebetsang pakeng tsa tsona. Matla ana a thibela dikarolwana ho dula fatshe ka tlhaho. Le hoja matla a kgoheli a ka baka karohano e sa fellang ha nako e ntse e ya, e kanna ya se sebetse bakeng sa ditshebetso tsa boholo ba indasteri moo nako e leng ya bohlokwa.

Karolo ea Centrifuge:

Sekontirifuge ke sesebediswa sa laboratori se sebedisang matla a sekontirifuge ho arola dikarolwana ho latela boholo ba tsona, sebopeho le bongata ba tsona. Ka ho potoloha ka lebelo le phahameng, sekontirifuge se etsisa matla a kgoheli a matla haholo ho feta matla a kgoheli a Lefatshe, e leng se dumellang karohano e potlakileng ya dikarolwana. Empa na sekontirifuge se ka arola dikarolwana tse hasaneng tsa colloid ka katleho?

Mokhoa oa ho Centrifugation

Ha motsoako oa colloid o kenngoa ka har'a centrifuge, o qala ho potoloha ka potlako. Matla a centrifugal a sebetsa ka mahlaseli a tsoang ka ntle 'me a hlahisa gradient ea khatello ka har'a motsoako. Gradient ena ea khatello e sutumelletsa likaroloana tse qhalakaneng ho ea moeling o ka ntle oa tube ea centrifuge, e leng se lebisang ho sedimentation. Gradient ea lebelo e thehoa ka har'a sampole, e leng se etsang hore likaroloana tse kholo li lule kapele ho feta likaroloana tse nyane.

Meeli ea Centrifugation

Leha ho centrifugation e le mokhoa o matla oa karohano ea likaroloana, e na le mefokolo ea eona ha ho tluoa likarolong tse hasaneng tsa colloid. Tšitiso e ka sehloohong ke boholo bo bonyenyane ba likaroloana tsena. Ka lebaka la litekanyo tsa tsona tse nyane, motsamao oa Brownian o ba oa bohlokoa, o etsang hore likaroloana li lule li emisitsoe nako e telele 'me o fokotsa katleho ea sedimentation. Ho feta moo, litefiso tsa motlakase holim'a libaka tsa likaroloana li ka sitisa ho kopana le ho lula.

Ho Hlōla Mathata

Ho hlola liphephetso tse amanang le ho arola likaroloana tsa colloid tse qhalakaneng, bafuputsi ba hlahlobile liphetoho tse fapaneng mekhoeng ea setso ea ho centrifugation. Mokhoa o mong o kenyelletsa ho eketsa li-coagulant kapa li-flocculant ho khothaletsa ho bokellana ha likaroloana, ho ntlafatsa ts'ebetso ea ho seda. Mokhoa o mong ke ts'ebeliso ea ultracentrifugation, e sebelisang lebelo le phahameng le meralo e tsoetseng pele ea rotor ho hlahisa matla a matla a centrifugal.

Mekhoa e Ntlafalitsoeng ea Centrifugation

Ntle le di-coagulant le ultracentrifugation, bo-rasaense ba hlahisitse mekgwa e meng ya ho ntlafatsa karohano ya dikarolwana tsa colloid tse hasaneng. Disebediswa tsa microfluidic, mohlala, di sebedisa dikanale tse nyane le matla a centrifugal ho nolofatsa tshebetso ya karohano ya dikarolwana. Dikanale tse entsweng ka nepo di hlahisa phallo ya laminar, di arola dikarolwana tsa colloidal ho tloha sepakapakeng ka katleho e kgolo.

Likopo tsa Liindasteri

Ho centrifugation ho bapala karolo ea bohlokoa lits'ebetsong tse fapaneng tsa indasteri. Indastering ea lijo le lino, ho thusa ho arola litšila kapa likaroloana tse tiileng ho metsi, ho netefatsa boleng bo holimo ba sehlahisoa. Likhamphani tsa meriana li itšetleha ka ho centrifugation ho hloekisa le ho arola likaroloana tse lakatsehang nakong ea nts'etsopele ea meriana. Ho feta moo, lifeme tsa kalafo ea metsi a litšila li sebelisa li-centrifuge ho tlosa lintho tse tiileng tse emisitsoeng le litšila tse ling metsing ka katleho, e leng se tlatsetsang tikolohong e hloekileng.

Qetello:

Leha dikarolwana tsa colloid tse qhalakaneng di baka diphephetso ho centrifuge, bafuputsi ba entse kgatelopele e kgolo ho ntshetseng pele mekgwa ya ho ntlafatsa karohano ya tsona. Ho fetola di-centrifuge tsa setso, ho kenyelletsa di-coagulant, le ho hlahloba disebediswa tse nyane ke mehlala e mmalwa feela ya kgatelopele e etswang. Ka ho utlwisisa mefokolo le ho hlahloba mawa a matjha, bo-rasaense ba ka notlolla bokgoni bo felletseng ba centrifuge bakeng sa ho arola dikarolwana tsa colloid tse qhalakaneng, ba fetola diindasteri tse fapaneng tshebetsong.
