• Nau'in centrifugation
• Misalai na centrifugation

The centrifugation Hanya ce ta raba abubuwa masu ƙarfi daga ruwa mai ɗimbin yawa a cikin cakuda, muddin tsohon ba ya narkewa, ta amfani da ƙarfin juyawa ko ƙarfin centrifugal.

Don wannan, ana amfani da kayan aikin da ake kira centrifuge ko centrifuge, wanda ke jujjuya cakuda akan madaidaiciya da ƙaddara.

Kamar yadda sunan ta ya nuna (centrifuge: gudu daga tsakiya), wannan ƙarfin yana ƙoƙarin tura abubuwan da suka fi yawa daga cikin juzu'in juyawa, yana barin ƙananan ƙananan a tsakiyar kanta. Ya saba da ƙarfin centripetal.

6. Abinci ga masu ciwon suga. Lokacin da yazo don raba furotin daga alkama daga abincin da ke ɗauke da shi, tsarin rarraba centrifugation yana da mahimmanci. Ana aiwatar da shi akan manna sitaci, wanda abun cikinsa ya kai 8%, kuma an rage shi zuwa ƙasa da 2% a cikin zaɓuɓɓukan zaɓuɓɓukan zaɓuɓɓuka.
7. Gwajin jini Ana amfani da centrifuge don rarrabe abubuwan jini, kamar plasma da sauran abubuwan da ake yawan haɗawa a ciki.
8. Kara hanzarin sedimentation. A cikin masana'antun abinci daban -daban, kamar yin giya ko hatsi, centrifugation yana hanzarta aiwatar da gurɓataccen gurɓataccen iska wanda ke haifar da raguwa, yana rage lokacin jira na albarkatun ƙasa.
9. Tsaftace latex. A cikin masana'antar latex, ya zama dole a tsabtace abu, wanda farfajiyar sa ta fi dacewa da bin wasu ƙwayoyin, kuma ana aiwatar da wannan ta hanyar centrifugation, saboda ƙarancin ƙarancin abu.
10. Bushewar daskararru. Wani aikace -aikacen masana'antu na centrifuge shine bushewar lu'ulu'u ko wasu kayan aikin da ruwa yake tare da samarwa. Yayin da yake jujjuyawa, ruwan yana rarrabewa daga daskararru kuma yana watsar, yana barin abubuwan da ake so ba tare da ruwa ba.
11. Maganin najasa. Tsayar da gurɓataccen ruwa yana ba da damar haɓakar abubuwa masu yawa a ciki, ba daskararru kawai ba, har ma da mai, kitse da sauran abubuwan da ba a so waɗanda, da zarar an datse su, ana iya watsar da su.
12. Gidan shakatawa. Yawancin wuraren shakatawa na nishaɗi suna amfani da ƙarfi na centrifugal don haifar da tasiri a kan mahayan su, waɗanda ke juyawa da sauri akan madaidaiciyar madaidaiciya, a haɗe a haɗe zuwa wurin zama wanda ke hana a fitar da su daga gindin juyawa.
13. Masu kera babur na Pirouette. Mai tuƙin babur a cikin wani fanni na gargajiya ne na circus, wanda ke iya tuƙa saman rufin da ke kare nauyi. Wannan yana da ikon yin hakan bayan ya yi juyi da yawa akan madaidaiciyar madaidaiciyar madaidaiciya, tara gudu da miƙawa ga ƙarfin centrifugal wanda ke manne da shi zuwa cikin sararin. Daga ƙarshe wannan ƙarfin zai yi girma sosai wanda zai iya tabbatar da motsi sosai kuma ya hana nauyi.
14. Karkashin hanyoyin jirgin ƙasa. Don ƙin ƙarfin centrifugal, sau da yawa ana karkatar da waƙoƙin jirgin ƙasa zuwa cikin lanƙwasa, suna yin juriya don kada ya faɗa kan ƙarfin da ke tura shi waje kuma baya ɓarna.
15. Fassarar duniya. Dalilin da yasa karfin Rana ba ya ingiza mu a cikin sa shi ma saboda karfin centrifugal wanda, lokacin juyawa akan axis na sarkin rana, yana tura shi waje, ya tunkari da daidaita jan hankali.
