indlela yokuhlukanisa ukhilimu nobisi nge-centrifugation ncert

Isingeniso:

I-Centrifugation iyindlela esetshenziswa kabanzi emikhakheni eyahlukene, okuhlanganisa nemboni yobisi. Idlala indima ebalulekile ekuhlukaniseni ukhilimu nobisi, okuholela emikhiqizweni enamafutha ahlukene. Kulesi sihloko, sizogxila enkambisweni yokuhlukanisa ukhilimu nobisi sisebenzisa i-centrifugation njengoba kuchaziwe kuMkhandlu Kazwelonke Wocwaningo Nokuqeqeshwa Kwezemfundo (NCERT). Sizohlola isayensi ngemuva kwe-centrifugation, izinyathelo ezihilelekile, izici ezithinta ukuhlukaniswa, kanye nokubaluleka kokuhlukaniswa kokhilimu ekukhiqizweni kwemikhiqizo yobisi.

I. Ukuqonda i-Centrifugation:

I-Centrifugation inqubo ehilela ukuhlukaniswa kwezingxenye ngaphakathi kwengxube ngokusekelwe ekuhlukeni kwazo kobuningi. Uma ubisi luphendulwa ngokushesha ku-centrifuge, izinhlayiya zokhilimu eziqinile ziyaphuma, kuyilapho ubisi olulula luhlala luseduze nesikhungo. Lokhu kuhlukaniswa kwenziwa lula ngamandla e-centrifugal akhiqizwa ukunyakaza kokujikeleza.

II. Inqubo Yokucisha Ugesi:

Ukuze uhlukanise ukhilimu nobisi usebenzisa i-centrifugation, izinyathelo ezilandelayo zivame ukuhileleka:

1. Ubisi olufudumele: Ubisi luqale lufudunyezwe lufike ezingeni lokushisa elithile. Lokhu kusiza ukuphazamisa noma yimaphi amaqoqo e-globule yamafutha emvelo akhona, okuvumela ukuhlukana kube lula.

2. Gcwalisa i-centrifuge: Ubisi olufudumele lufakwa ezitsheni ze-centrifuge. Kufanele kuqashelwe ukuthi ungagcwalisi umshini ngokweqile, njengoba lokhu kungathinta ukusebenza kahle kokuhlukanisa.

3. Ukufakwa kwe-Centrifugation: Izitsha ezilayishiwe zifakwa ku-centrifuge bese ziphenduphenduka ngokushesha. Amandla e-centrifugal akhiqizwayo abangela ukuthi izinhlayiya zokhilimu eziqinile zihambe ziye odongeni lwangaphandle lwesitsha, kuyilapho ubisi luhlala phakathi nendawo.

4. Ukuqoqwa kokhilimu: Uma inqubo yokuxuba isiqediwe, ukhilimu uqoqwa ngokucophelela kusuka phezulu kwesitsha. Lokhilimu uvame ukuqukethe iphesenti eliphezulu lamafutha kunobisi olufakwe ekuqaleni.

III. Izici Ezithinta Ukuhlukaniswa Kwekhilimu:

1. Okuqukethwe kwamafutha obisi: Okuqukethwe kwamafutha obisi kuthinta ngqo inani kanye nekhwalithi yokhilimu otholakalayo. Ubisi olunamafutha amaningi lukhiqiza ukhilimu onephesenti elikhulu lamafutha.

2. Isivinini nesikhathi se-Centrifuge: Isivinini kanye nobude be-centrifuge kuthinta ukusebenza kahle kokuhlukaniswa kokhilimu. Kudingeka kunqunywe izilungiselelo ezifanele zezinhlobo ezahlukene zobisi kanye nemikhiqizo yokhilimu oyifunayo.

3. Izinga Lokushisa: Izinga lokushisa lapho inqubo yokuhlukanisa iyenzeka khona lithinta ukujiya kokhilimu kanye nokulula kokuhlukana. Izinga lokushisa elithile lingase liveze imiphumela engcono ngenxa yezinguquko ezimpahleni ze-fat globule.

4. Izinga lokujikeleza: Izinga lapho i-centrifuge ijikeleza khona lidlala indima ebalulekile ekuhlukaniseni. Izinga lokujikeleza eliphezulu kakhulu noma eliphansi kakhulu lingathinta isivuno sokhilimu, ikhwalithi, kanye nokuqina.

5. Umklamo we-Centrifuge: Uhlobo kanye nomklamo we-centrifuge esetshenzisiwe nakho kuthinta inqubo yokuhlukanisa. Izici ezifana nesimo sesitsha, umthamo, kanye nomklamo we-rotor zinquma ubukhulu bokuhlukaniswa kokhilimu.

IV. Ukubaluleka Kokuhlukaniswa Kokhilimu:

Ukuhlukaniswa kokhilimu kuyisinyathelo esibalulekile ekukhiqizweni kwemikhiqizo yobisi ehlukahlukene. Ezinye zezicelo ezibalulekile zifaka:

1. Ukukhiqizwa kwebhotela: Ukhilimu ohlukaniswe nobisi usetshenziswa njengesithako esiyinhloko ekukhiqizweni kwebhotela. Ngokuhlanganisa ukhilimu, ama-globules amafutha ayahlangana futhi akhe ibhotela.

2. Ukukhiqizwa kwama-dessert asekelwe kukhilimu: Ukuhlukaniswa kokhilimu kusiza ekutholeni ukhilimu onamafutha ahlukene adingekayo ekukhiqizweni kwama-dessert afana nama-ayisikhilimu, ama-whipped cream, nama-custard.

3. Ukukhiqizwa kobisi olukhishwe ubisi olunamafutha amancane: Ngemva kokuhlukaniswa kokhilimu, ubisi olusele lungacutshungulwa kabanzi ukuze kukhiqizwe ubisi olukhishwe ubisi olunamafutha amancane, olunamafutha amancane. Lusetshenziswa njengendlela engcono yokudla emikhiqizweni yokudla ehlukahlukene.

4. Imikhiqizo yobisi eyenziwe ngokwezifiso: Ukuhlukaniswa kokhilimu kunikeza ukuguquguquka ekukhiqizeni imikhiqizo yobisi enokuqukethwe kwamafutha athile, okuhambisana nezintandokazi zabathengi kanye nezidingo zokudla.

Isiphetho:

I-Centrifugation iyindlela ewusizo yokuhlukanisa ukhilimu nobisi embonini yobisi. Le nqubo ivumela ukukhiqizwa kwemikhiqizo yobisi ehlukahlukene enokuqukethwe okunamafutha ahlukene, okuhlangabezana nezidingo zabathengi ezahlukahlukene. Ukuqonda isayensi ngemuva kwe-centrifugation, ukulandela inqubo efanele, nokucabangela izici ezibalulekile ezithinta ukuhlukaniswa kokhilimu kubalulekile ekutholeni imiphumela emihle. Ngokusebenzisa iziqondiso ze-NCERT nokufaka intuthuko kwezobuchwepheshe, imboni yobisi iyaqhubeka nokuthuthukisa amasu okuhlukanisa ukhilimu ukuze kuthuthukiswe ukusebenza kahle kanye nekhwalithi ekukhiqizweni komkhiqizo wobisi.
