ingaba amasuntswana e-colloid asasazekileyo angahlukana kwi-centrifuge
Ngaba iinxalenye zeColloid ezisasazekileyo zingahlukana kwiCentrifuge?
Intshayelelo:
IiColloids luhlobo olulodwa lwento apho amasuntswana asasazwa ngokulinganayo kuyo yonke into ephakathi, nto leyo eyenza umxube ozinzileyo. Imizekelo yeecolloids ibandakanya igelatin, ubisi, kunye nekrimu etyumziweyo. Ukwahlula amasuntswana ecolloid asasazekileyo kwi-medium kunokuba nzima ngenxa yobukhulu bawo obuncinci kunye nokusasazwa ngokulinganayo. Kweli nqaku, sihlola ukuba i-centrifugation inokwahlula ngokufanelekileyo amasuntswana ecolloid asasazekileyo kwaye sixoxe ngemida yayo kunye nokusetyenziswa kwayo okunokwenzeka.
Ukuqonda iiColloid Particles:
Iinxalenye zeColloid zinobukhulu obuqala kwiinanometers ukuya kwiimicrometers. Zihlala zikwimeko yokusasazeka, zigcina ulungelelwaniso oluzinzileyo ngenxa yamandla anomtsalane narhabaxa asebenza phakathi kwazo. La mandla athintela iinxalenye ukuba zingahlali ngokwendalo. Nangona umxhuzulane unokubangela ukwahlukana okungaphelelanga ngokuhamba kwexesha, kusenokungabi luncedo kwiinkqubo zesikali semizi-mveliso apho ixesha libaluleke kakhulu.
Indima yeCentrifuge:
I-centrifuge sisixhobo selabhoratri esisebenzisa amandla e-centrifugal ukwahlula amasuntswana ngokusekelwe kubukhulu bawo, imilo, kunye noxinano. Ngokujikeleza ngesantya esiphezulu, i-centrifuge ilinganisa amandla axhuzulayo anamandla kakhulu kunomxhuzulane woMhlaba, okuvumela ukwahlukana kwamasuntswana ngokukhawuleza. Kodwa ngaba i-centrifuge ingawahlula ngempumelelo amasuntswana e-colloid asasazekileyo?
Indlela yoNxibelelwano lweCentrifugation
Xa umxube we-colloid ufakwa kwi-centrifuge, uqala ukujikeleza ngokukhawuleza. Amandla e-centrifugal asebenza nge-radially ngaphandle kwaye avelise i-pressure gradient ngaphakathi komxube. Olu xinzelelo lutyhala amasuntswana asasazekileyo aye kumda ongaphandle wetyhubhu ye-centrifuge, nto leyo ekhokelela ekutsalweni kwenkunkuma. I-Velocity gradients imiselwa ngaphakathi kwesampuli, nto leyo ebangela ukuba amasuntswana amakhulu azinze ngokukhawuleza kuneamasuntswana amancinci.
Imida yeCentrifugation
Nangona i-centrifugation iyindlela enamandla yokwahlulahlula amasuntswana, inemida yayo xa kufikwa kumasuntswana e-colloid asasazekileyo. Umqobo ophambili bubungakanani obuncinci bamasuntswana. Ngenxa yobukhulu bawo obuncinci, intshukumo yeBrownian iba nkulu, nto leyo ebangela ukuba amasuntswana ahlale emile ixesha elide kwaye inciphise ukusebenza kakuhle kwe-sedimentation. Ukongeza, iitshaja ze-electrostatic kumphezulu wamasuntswana zinokuthintela ukuhlangana kunye nokuhlaliswa.
Ukoyisa Imingeni
Ukuze boyise imingeni enxulumene nokwahlulahlula amasuntswana e-colloid asasazekileyo, abaphandi bahlolisise utshintsho olwahlukeneyo kwiindlela zemveli zokufaka i-centrifugation. Enye indlela ibandakanya ukongezwa kwama-coagulants okanye ama-flocculants ukukhuthaza ukuhlanganiswa kwamasuntswana, ukuphucula inkqubo yokufakwa kwe-sedimentation. Enye indlela kukusebenzisa i-ultracentrifugation, kusetyenziswa isantya esiphezulu nangakumbi kunye noyilo oluphambili lwe-rotor ukuvelisa amandla anamandla e-centrifugal.
Iindlela zokuphucula i-Centrifugation
Ngaphandle kwe-coagulants kunye ne-ultracentrifugation, izazinzulu ziye zaphuhlisa ezinye iindlela zokuphucula ukwahlukana kwee-colloid particles ezisasazekileyo. Izixhobo ze-Microfluidic, umzekelo, zisebenzisa ii-microchannels kunye ne-centrifugal forces ukwenza lula inkqubo yokwahlukana kwee-particles. Ii-channels ezenziwe ngokuchanekileyo zenza ukuhamba kwe-laminar, zihlukanisa ii-colloidal particles kwi-medium ngokufanelekileyo.
Izicelo zeShishini
Ukucoca amanzi amdaka kudlala indima ebalulekileyo kwizicelo ezahlukeneyo zoshishino. Kwishishini lokutya neziselo, kunceda ukwahlula ukungcola okanye amasuntswana aqinileyo kwizinto ezimanzi, kuqinisekisa umgangatho ophezulu wemveliso. Iinkampani zamayeza zixhomekeke ekucoceni nasekuhlukaniseni amasuntswana afunekayo ngexesha lophuhliso lwamayeza. Ngaphezu koko, izityalo zonyango lwamanzi amdaka zisebenzisa ii-centrifuges ukususa ngokufanelekileyo izinto eziqinileyo ezixhonyiweyo kunye nezinye izinto ezingcolisayo emanzini, nto leyo enegalelo ekucocekeni kweendawo ezingqongileyo.
Isiphelo:
Nangona amasuntswana e-colloid asasazekileyo ebangela imingeni kwi-centrifugation, abaphandi benze inkqubela phambili enkulu ekuphuhliseni iindlela zokuphucula ukwahlukana kwawo. Ukutshintsha ii-centrifuge zemveli, ukufaka ii-coagulants, kunye nokuhlola izixhobo ze-microfluidic yimizekelo embalwa yenkqubela phambili eyenziwayo. Ngokuqonda imida kunye nokuhlola amaqhinga amatsha, izazinzulu zinokuvula amandla apheleleyo e-centrifugation okwahlula amasuntswana e-colloid asasazekileyo, ziguqule amashishini ahlukeneyo kule nkqubo.
