chitha kusungunuka. Madontho amatha kulekanitsidwa ndi centrifuge

Nkhani:

Chiyambi:

Kugawa zinthu m'maselo ndi njira yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo mankhwala, sayansi ya zamoyo, ndi chemistry. Ikuphatikizapo kulekanitsa zigawo mu chisakanizo kutengera kusiyana kwa kuchuluka kwawo. Funso limodzi losangalatsa lomwe limabuka ndilakuti ngati zinthu zosasungunuka zitha kulekanitsidwa bwino pogwiritsa ntchito centrifuge. M'nkhaniyi, tifufuza zomwe zingatheke komanso zolephera za centrifuge pogawa zinthu zosasungunuka.

1. Kumvetsetsa Ma Insoluble Precipitates:

Kuti mumvetse ngati ma precipitates osasungunuka angathe kulekanitsidwa ndi centrifuge, ndikofunikira choyamba kumvetsetsa kuti ma precipitates amenewa ndi otani. Ma precipitates osasungunuka ndi tinthu tolimba tomwe timapangidwa pamene zinthu ziwiri kapena zingapo zosungunuka zimagwirizana. Tinthu timeneti sitisungunuka mu solvent ndipo nthawi zambiri timakhazikika pansi pa chidebecho. Kuzilekanitsa ndi gawo lamadzimadzi kungakhale kovuta popanda kugwiritsa ntchito njira zinazake monga centrifugation.

2. Mfundo ya Centrifugation:

Kutsegula magetsi pogwiritsa ntchito njira ya sedimentation, komwe tinthu tating'onoting'ono tomwe timasakaniza timakhazikika chifukwa cha mphamvu yokoka. Kutsegula magetsi kumafulumizitsa njirayi pogwiritsa ntchito mphamvu ya centrifugal, yomwe imayendetsa tinthuto kupita kumakoma a chubu cha centrifuge. Mphamvu yomwe imagwiritsidwa ntchito imadalira liwiro lozungulira ndi radius ya rotor ya centrifuge. Pogwiritsa ntchito njira imeneyi, zinthu zimatha kulekanitsidwa kutengera kusiyana kwa kuchuluka kwawo. Komabe, zinthu zosasungunuka zimakhala ndi makhalidwe apadera omwe angayambitse mavuto pakulekanitsidwa kwawo.

3. Mavuto Olekanitsa Madzi Osasungunuka:

Kulekanitsa ma precipitates osasungunuka pogwiritsa ntchito centrifugation kungakumane ndi zopinga zingapo. Choyamba, ma precipitates nthawi zambiri amakhala ndi liwiro lalikulu lokhazikika, zomwe zimapangitsa kuti centrifuge ikhale ndi mphamvu zokwanira kuti ithane ndi sedimentation yawo. Kuphatikiza apo, kukula ndi mawonekedwe a ma precipitates amatha kukhudza momwe njira yolumikizira ma centrifugation imagwirira ntchito. Ma precipitates akuluakulu komanso osawoneka bwino sangalekanitsidwe bwino, zomwe zimapangitsa kuti zotsatira zake zikhale zoipa. Kuphatikiza apo, ma precipitates ena amatha kupanga ma aggregates, zomwe zimapangitsa kuti kulekanitsidwa kwawo kukhale kovuta kwambiri kudzera mu centrifugation.

4. Kukonza Bwino Kulekana Kwabwino:

Ngakhale pali zovuta, njira zingapo zingagwiritsidwe ntchito kuti zithetse kulekanitsa kwa ma precipitate osasungunuka pogwiritsa ntchito centrifuge. Njira imodzi yotereyi ndi kuwonjezera zinthu zozungulira kapena ma coagulant. Zinthuzi zimathandiza kuti tinthu tating'onoting'ono tomwe timapanga ma precipitate tizikuluzikulu komanso tomwe timatha kulekanitsidwa mosavuta. Mwa kupanga ma aggregates akuluakulu, ma precipitatewo samakhala osavuta kubwereranso panthawi ya centrifuge, motero amathandiza kuti kulekanitsa kukhale bwino.

5. Mitundu ya Ma Centrifuge Opatukana ndi Mpweya:

Mitundu yosiyanasiyana ya ma centrifuge ingagwiritsidwe ntchito kulekanitsa ma precipitates osasungunuka, makamaka kutengera kuchuluka ndi mawonekedwe a chitsanzocho. Ma centrifuge othamanga kwambiri nthawi zambiri amagwiritsidwa ntchito m'ma laboratories komwe zitsanzo zochepa zikukonzedwa. Ma centrifuge awa amatha kukhala ndi liwiro lalikulu lozungulira, zomwe zimapangitsa kuti pakhale mphamvu zamphamvu za centrifugal kuti pakhale kulekanitsa koyenera. Kumbali ina, njira zazikulu zamafakitale zingagwiritse ntchito ma centrifuge opitilira, omwe amapereka mphamvu zambiri komanso kukula bwino.

Mapeto:

Pomaliza, ngakhale kulekanitsa ma precipitates osasungunuka kungakhale kovuta, centrifugation ikhoza kukhala njira yothandiza kwambiri pakulekanitsa kwawo pansi pa zochitika zoyenera. Zinthu monga kukhazikika kwa liwiro, kukula kwa tinthu, ndi mawonekedwe zimagwira ntchito yofunika kwambiri pakudziwa kupambana kwa njira yolekanitsira. Kudzera mu njira zowongolera monga flocculation ndi kugwiritsa ntchito mtundu woyenera wa centrifuge, ma precipitates osasungunuka amatha kulekanitsidwa bwino, zomwe zimathandiza mafakitale osiyanasiyana kuti azitha kusintha njira zawo ndikuwonjezera ubwino wa zinthu.
