momwe mungasiyanitsire kirimu ndi mkaka pogwiritsa ntchito centrifugation ncert

Chiyambi:

Kugawa mafuta m'maselo ndi njira yomwe imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana, kuphatikizapo makampani opanga mkaka. Imagwira ntchito yofunika kwambiri pakugawa mafuta m'maselo, zomwe zimapangitsa kuti pakhale zinthu zosiyanasiyana zomwe zimakhala ndi mafuta osiyanasiyana. M'nkhaniyi, tikambirana za njira yogawa mafuta m'maselo pogwiritsa ntchito kugawa mafuta m'maselo monga momwe zafotokozedwera mu National Council of Educational Research and Training (NCERT). Tidzafufuza sayansi ya kugawa mafuta m'maselo, njira zomwe zimakhudzidwa, zinthu zomwe zimakhudza kulekanitsa, komanso kufunika kwa kulekanitsa mafuta m'maselo popanga mkaka.

I. Kumvetsetsa Centrifugation:

Kugawanitsa mkaka ndi njira yomwe imaphatikizapo kulekanitsa zigawo mkati mwa chisakanizo kutengera kusiyana kwa kuchuluka kwawo. Pamene mkaka ukuzunguliridwa mofulumira mu centrifuge, tinthu ta kirimu tokhuthala timapita kunja, pomwe mkaka wopepuka umakhala pafupi ndi pakati. Kulekanitsa kumeneku kumathandizidwa ndi mphamvu ya centrifugal yomwe imapangidwa ndi kayendedwe ka kuzungulira.

II. Njira Yogwiritsira Ntchito Centrifugation:

Kuti mulekanitse kirimu ndi mkaka pogwiritsa ntchito centrifugation, njira zotsatirazi nthawi zambiri zimagwiritsidwa ntchito:

1. Mkaka wofunda: Poyamba mkaka umatenthedwa kufika kutentha kwinakwake. Izi zimathandiza kusokoneza magulu onse amafuta achilengedwe omwe alipo, zomwe zimathandiza kuti pakhale kusiyana kosavuta.

2. Dzazani centrifuge: Mkaka wofunda umayikidwa m'zidebe za centrifuge. Samalani kuti musachulukitse makina, chifukwa izi zingakhudze magwiridwe antchito a kulekanitsa.

3. Kutsegula payipi: Zidebe zodzaza zimayikidwa mu centrifuge ndipo zimazunguliridwa mofulumira. Mphamvu ya centrifugal yomwe imapezeka imapangitsa kuti tinthu ta kirimu tokhuthala tisunthire ku khoma lakunja la chidebecho, pomwe mkaka umakhalabe pakati.

4. Kusonkhanitsa kirimu: Ntchito yothira mafuta ikatha, kirimuyo imatengedwa mosamala kuchokera pamwamba pa chidebecho. Kirimuyu nthawi zambiri amakhala ndi mafuta ambiri kuposa mkaka womwe unayikidwa poyamba.

III. Zinthu Zomwe Zimakhudza Kulekanitsa Kirimu:

1. Kuchuluka kwa mafuta a mkaka: Kuchuluka kwa mafuta mu mkaka kumakhudza mwachindunji kuchuluka ndi ubwino wa kirimu yomwe imapezeka. Mkaka wokhala ndi mafuta ambiri umapanga kirimu yokhala ndi mafuta ambiri.

2. Liwiro la centrifuge ndi nthawi: Liwiro ndi nthawi ya centrifuge zimakhudza momwe mafuta amagawidwira bwino. Makonzedwe abwino a mitundu yosiyanasiyana ya mkaka ndi zinthu zopaka mafuta ziyenera kutsimikiziridwa.

3. Kutentha: Kutentha komwe njira yolekanitsira mafuta imachitikira kumakhudza kukhuthala kwa kirimu ndi kusavuta kwake kulekanitsa mafuta. Kutentha kwina kungapereke zotsatira zabwino chifukwa cha kusintha kwa mafuta m'thupi.

4. Kuthamanga kwa kasinthasintha: Kuthamanga kwa kasinthasintha kamene ka centrifuge kamazungulira kumachita gawo lofunika kwambiri pakulekanitsa. Kuthamanga kwa kasinthasintha kokwera kwambiri kapena kotsika kwambiri kungakhudze kukolola kwa kirimu, ubwino wake, ndi kukhazikika kwake.

5. Kapangidwe ka Centrifuge: Mtundu ndi kapangidwe ka centrifuge yomwe imagwiritsidwa ntchito zimakhudzanso njira yolekanitsira. Zinthu monga mawonekedwe a chidebe, mphamvu, ndi kapangidwe ka rotor zimatsimikiza kukula kwa kulekanitsa kirimu.

IV. Kufunika kwa Kulekanitsa Kirimu:

Kulekanitsa kirimu ndi gawo lofunika kwambiri pakupanga zinthu zosiyanasiyana za mkaka. Ntchito zina zofunika kwambiri ndi izi:

1. Kupanga batala: Kirimu wopatulidwa ndi mkaka umagwiritsidwa ntchito ngati chinthu chachikulu popanga batala. Popanga kirimu, mafuta amaphatikizana ndikupanga batala.

2. Kupanga makeke opangidwa ndi kirimu: Kusiyanitsa kirimu kumathandiza kupeza kirimu yokhala ndi mafuta osiyanasiyana ofunikira popanga makeke opangidwa ndi kirimu monga ayisikilimu, makeke ophwanyidwa, ndi makastadi.

3. Kupanga mkaka wopanda mafuta: Pambuyo pochotsa kirimu, mkaka wotsalawo ukhoza kukonzedwanso kuti upange mkaka wopanda mafuta, womwe uli ndi mafuta ochepa. Umagwiritsidwa ntchito ngati njira ina yabwino m'zakudya zosiyanasiyana.

4. Zakudya za mkaka zomwe zakonzedwa mwamakonda: Kusiyanitsa kirimu kumapereka kusinthasintha popanga mkaka wokhala ndi mafuta enaake, zomwe zimagwirizana ndi zomwe ogula amakonda komanso zakudya zomwe amafunikira.

Mapeto:

Kugawa mkaka m'mafakitale a mkaka ndi njira yothandiza kwambiri yolekanitsira kirimu ndi mkaka m'makampani opanga mkaka. Njirayi imalola kupanga mitundu yosiyanasiyana ya mkaka yokhala ndi mafuta osiyanasiyana, zomwe zimakwaniritsa zosowa zosiyanasiyana za ogula. Kumvetsetsa sayansi ya kugawa mkaka m'mafakitale, kutsatira njira yoyenera, ndikuganizira zinthu zazikulu zomwe zimakhudza kulekanitsa kirimu ndikofunikira kwambiri kuti mupeze zotsatira zabwino. Pogwiritsa ntchito malangizo a NCERT ndikuyika patsogolo ukadaulo, makampani opanga mkaka akupitilizabe kukulitsa njira zogawa mkaka kuti ziwongolere magwiridwe antchito komanso mtundu wake popanga mkaka.
