Kodi mungagwiritse ntchito centrifugation kulekanitsa madzi ndi mchenga?

Chiyambi

Kugawa madzi ndi njira yomwe imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana asayansi yomwe imaphatikizapo kulekanitsa zosakaniza kutengera kuchuluka kwawo pogwiritsa ntchito mphamvu ya centrifugal. Munkhaniyi, tifufuza ngati kugawa madzi ndi mchenga kungagwiritsidwe ntchito bwino pogawa madzi ndi mchenga. Tidzayang'ana kwambiri mfundo za kugawa madzi ndi mchenga, makhalidwe a madzi ndi mchenga, ndikukambirana mavuto ndi mayankho omwe angagwiritsidwe ntchito pogawa zinthu ziwirizi bwino. Tiyeni tiyambe!

Kumvetsetsa Centrifugation

Musanafufuze za kulekanitsa madzi ndi mchenga pogwiritsa ntchito centrifugation, ndikofunikira kumvetsetsa mfundo zoyambira za njira iyi. Centrifugation imagwira ntchito pozungulira chitsanzo pa liwiro lalikulu, zomwe zimapangitsa mphamvu ya centrifugal yomwe imakankhira tinthu kuti tisiyanitse kutengera kuchuluka kwake. Tinthu tolemera timakonda kupita kumphepete kwakunja kwa chipinda chozungulira, pomwe tinthu topepuka tingakhale pafupi ndi pakati.

Katundu wa Madzi ndi Mchenga

Madzi, omwe ndi osungunulira ofunikira komanso ogwiritsidwa ntchito padziko lonse lapansi, ali ndi kuchuluka kwa pafupifupi gramu imodzi pa sentimita imodzi (g/cm³) kutentha kwa chipinda. Ndi molekyulu ya polar, zomwe zimapangitsa kuti ikhale yoyenera kusungunula ndi kunyamula zinthu zosiyanasiyana. Kumbali ina, mchenga umakhala ndi silicon dioxide (SiO₂) ndipo uli ndi kuchuluka kwakukulu poyerekeza ndi madzi, pafupifupi 2.65 g/cm³.

Mavuto Olekanitsa Madzi ndi Mchenga

Kulekanitsa madzi ndi mchenga kumabweretsa vuto lalikulu chifukwa cha kusiyana kwa kuchulukana kwawo, chifukwa tinthu ta mchenga timakhala tolimba kwambiri kuposa madzi. Tinthu ta mchenga tikasakanikirana, tinthu ta mchenga timakonda kumira mofulumira, zomwe zimapangitsa kuti njira zodziwika bwino zosefera kapena zosungunulira nthaka zisagwire ntchito. Kuthetsa vutoli kumafuna kugwiritsa ntchito centrifugation, pakati pa njira zina zomwe zingatheke, kuti tipeze kulekanitsa kogwira mtima.

Kugwiritsa Ntchito Centrifugation Polekanitsa Madzi ndi Mchenga

Kuti mulekanitse madzi ndi mchenga pogwiritsa ntchito centrifugation, pali njira zingapo zofunika zomwe ziyenera kutsatiridwa. Tiyeni tikambirane mwatsatanetsatane njira izi pansipa.

1. Kukonzekera Chitsanzo

Kusakaniza kwa madzi ndi mchenga kuyenera kukonzedwa bwino musanazigwiritse ntchito mu centrifugation. Gawo loyamba ndikupeza chitsanzo chosakanikirana bwino, kuonetsetsa kuti mchenga wagawidwa mofanana m'madzi onse.

2. Kusankha kwa Centrifuge

Kusankha centrifuge yoyenera ndikofunikira kuti pakhale kulekanitsa bwino. Centrifuge iyenera kukhala ndi mphamvu yogwiritsira ntchito kuchuluka kwa zitsanzo pamene ikupereka mphamvu yokwanira yozungulira kuti ikankhire tinthu ta mchenga ku makoma a chubu cha centrifuge kapena chidebecho.

3. Magawo a Centrifugation

Kudziwa magawo oyenera a centrifugation ndikofunikira kwambiri. Zinthu monga liwiro la centrifuge (kuzungulira pamphindi, kapena rpm) ndi nthawi zimathandiza kwambiri pakulekanitsa madzi ndi mchenga bwino. Kuyesera kungakhale kofunikira kuti zinthu ziyende bwino pa chisakanizo chilichonse.

4. Njira Yopangira Centrifugation

Mukapeza njira zoyenera zogwiritsira ntchito, chisakanizocho chiyenera kuyikidwa mosamala m'machubu kapena m'zidebe zoyenera zoyezera kutentha. Kuyika machubuwo pa ngodya mkati mwa choyezera kutentha kungathandize kulekanitsa madzi ndi mchenga bwino.

5. Kusanthula Zotsatira

Mukamaliza kugawa madzi m'ma centrifugation, yang'anani zigawo zolekanitsidwa mu chubu kapena chidebecho. Ngati zatheka, tinthu ta mchenga tidzakanikizidwa bwino m'mphepete mwa madzi pomwe madziwo amakhala pafupi ndi pakati. Chotsani mosamala gawo la mchenga ndikusonkhanitsa madzi otsalawo, ndikumaliza njira yolekanitsira.

Mapeto

Kugawa madzi ndi njira yothandiza kwambiri pogawa madzi ndi mchenga. Pogwiritsa ntchito mphamvu ya centrifugal yomwe imapangidwa panthawi yozungulira mofulumira, zimakhala zotheka kugawa zinthu ziwirizi kutengera kusiyana kwa kuchuluka kwa madzi. Ngakhale kuti pali zovuta chifukwa cha kuchuluka kwa madzi m'mchenga, kusankha njira yoyenera yogawa madzi ndikuwongolera magawo a centrifugation kumatha kuthana ndi zopinga izi. Kuyesa kwina kungapangitse kuti pakhale njira zabwino zopezera madzi ndi mchenga.
