iimvula zingahlulwa nge-centrifuge
Inqaku:
Intshayelelo:
I-Centrifugation yindlela esetyenziswa kakhulu kumashishini ahlukeneyo, kuquka amayeza, i-biotechnology, kunye ne-chemistry. Ibandakanya ukwahlulahlula izinto kumxube ngokusekelwe kumahluko wazo wobuninzi. Umbuzo omnye onomdla ophakamayo kukuba ingaba ii-precipitates ezinganyibilikiyo zinokuhlulwa ngokufanelekileyo kusetyenziswa i-centrifuge. Kweli nqaku, siza kuphonononga amathuba kunye nemida ye-centrifugation yokwahlula ii-precipitates ezinganyibilikiyo.
1. Ukuqonda iiNqanaba ezinganyibilikiyo:
Ukuze uqonde ukuba iiprecipitates ezinganyibilikiyo zinokuhlulwa yi-centrifuge, kubalulekile kuqala ukuqonda ukuba zeziphi ezi precipitates. Iiprecipitates ezinganyibilikiyo zii-solid particles ezibumbeka xa izinto ezimbini okanye ngaphezulu ezinyibilikayo zisabelana. Ezi particles azinyibiliki kwi-solvent kwaye zihlala zihlala ezantsi kwesikhongozeli. Ukuzahlula kwi-liquid phase kunokuba nzima ngaphandle kokusebenzisa iindlela ezithile ezifana ne-centrifugation.
2. Umgaqo weCentrifugation:
I-Centrifugation isebenzisa umgaqo we-sedimentation, apho amasuntswana kumxube wolwelo adla ngokuhlala ngenxa yomxhuzulane. I-centrifuge ikhawulezisa le nkqubo ngokusebenzisa amandla e-centrifugal, aqhubela amasuntswana kwiindonga zetyhubhu ye-centrifuge. Amandla asetyenziswayo axhomekeke kwisantya sokujikeleza kunye ne-radius ye-centrifuge rotor. Ngokusebenzisa le ndlela, izinto zinokwahlulwa ngokusekelwe kumahluko wazo woxinano. Nangona kunjalo, ii-precipitates ezinganyibilikiyo zineempawu ezizodwa ezinokubangela imingeni ekuhlukaneni kwazo.
3. Imingeni yokwahlula iiNgxaki ezinganyibilikiyo:
Ukwahlula iiprecipitates ezinganyibilikiyo kusetyenziswa i-centrifugation kunokuhlangabezana nemiqobo embalwa. Okokuqala, iiprecipitates zihlala zinesantya esiphezulu sokuzinza, nto leyo eyenza kube nzima ukuba i-centrifuge isebenzise amandla aneleyo okumelana nokuthuthwa kwazo. Ukongeza, ubungakanani kunye nokuma kweeprecipitates kunokuchaphazela ukusebenza kwenkqubo ye-centrifugation. Iiprecipitates ezinkulu nezimilo zingalinganiyo zisenokungahlukani ngokufanelekileyo, nto leyo ekhokelela kwiziphumo ezimbi. Ngaphezu koko, ezinye iiprecipitates zinokwenza ii-aggregates, nto leyo enokwenza kube nzima ngakumbi ukwahlukana kwazo nge-centrifugation.
4. Ukuphucula Ukwahlukana Okusebenzayo:
Nangona kukho imingeni, amaqhinga aliqela anokusetyenziswa ukuphucula ukwahlulahlula iiprecipitates ezinganyibilikiyo kusetyenziswa i-centrifuge. Enye yeendlela ezinjalo kukongeza ii-flocculating agents okanye ii-coagulants. Ezi zinto zenza kube lula ukuhlanganiswa kwee-precipitate particles ezincinci zibe ziingceba ezinkulu nezinokuhlulwa lula. Ngokwenza ii-aggregates ezinkulu, iiprecipitates aziba lula ukuphinda zixhonywe ngexesha le-centrifuge, ngaloo ndlela ziphucula ukusebenza kakuhle kokwahlukana.
5. Iintlobo zeeCentrifuges zoKwahlula iNgxaki:
Iindidi ezahlukeneyo zee-centrifuge zingasetyenziselwa ukwahlula ii-precipitates ezinganyibilikiyo, ngakumbi kuxhomekeke kubungakanani kunye neempawu zesampulu. Ii-centrifuge ezinesantya esiphezulu zihlala zisetyenziswa kwiilabhoratri apho kucutshungulwa khona inani elincinci leesampuli. Ezi centrifuge zinokufikelela kwisantya esiphezulu sokujikeleza, nto leyo ekhokelela kumandla aqinileyo e-centrifugal ukuze kwahlulwe ngokufanelekileyo. Kwelinye icala, iinkqubo ezinkulu zoshishino zinokusebenzisa ii-centrifuge eziqhubekayo, ezibonelela nge-throughput ephezulu kunye nokukhula okungcono.
Isiphelo:
Ukuqukumbela, nangona ukwahlulahlula iiprecipitates ezinganyibilikiyo kunokuba ngumceli mngeni, i-centrifugation inokuba yindlela exabisekileyo yokwahlulahlula phantsi kweemeko ezifanelekileyo. Izinto ezinje ngesantya sokulungisa, ubungakanani besuntswana, kunye nemilo zidlala indima ebalulekileyo ekumiseleni impumelelo yenkqubo yokwahlulahlula. Ngokusebenzisa iindlela zokwenza ngcono ezifana ne-flocculation kunye nokusebenzisa uhlobo olufanelekileyo lwe-centrifuge, iiprecipitates ezinganyibilikiyo zinokuhlulwa ngokufanelekileyo, okuvumela amashishini ahlukeneyo ukuba enze lula iinkqubo zawo kwaye aphucule umgangatho wemveliso.
