Kodi ma colloid angalekanitsidwe ndi centrifugation

Colloids: Kuyang'ana Kwambiri Njira Zogwiritsira Ntchito Centrifugation ndi Kulekanitsa

Chiyambi:

Ma Colloid ndi gulu losangalatsa komanso lopezeka paliponse la zinthu zomwe zimapezeka m'zinthu zosiyanasiyana zachilengedwe komanso zopangidwa. Zosakaniza izi zimapangidwa ndi tinthu tating'onoting'ono tomwe timafalikira mu sing'anga yopitilira, zomwe zimapangitsa kuti pakhale njira yokhazikika komanso yowoneka bwino. Ngakhale kuti amawoneka ofanana, ma colloid atsimikizira kuti ndi ovuta kwambiri pankhani yolekanitsa ndi kudzipatula kwawo.

Munkhaniyi, tikuyang'ana kwambiri dziko la ma colloid, makamaka pa momwe centrifugation imagwirira ntchito ngati njira yolekanitsira. Tidzafufuza momwe ma colloid angalekanitsidwire pogwiritsa ntchito ma centrifuge, mfundo zomwe zili kumbuyo kwa njirayi, ndikuwunikira kufunika komvetsetsa makhalidwe a colloidal m'mafakitale monga mankhwala, chakudya, ndi sayansi ya zachilengedwe.

I. Kumvetsetsa Ma Colloid ndi Makhalidwe Awo:

Musanaphunzire njira zolekanitsira, ndikofunikira kumvetsetsa mtundu wa ma colloid. Tinthu ta Colloidal timagawika m'magulu atatu: olimba omwe amamwazika m'madzi, madzi omwe amamwazika m'madzi, ndi mpweya womwe umamwazika m'madzi. Chizindikiro cha ma colloid ndi kukula kwawo, nthawi zambiri kuyambira nanometer imodzi mpaka micrometer imodzi m'mimba mwake.

Machitidwe a Colloidal ali ndi makhalidwe apadera chifukwa cha malo akuluakulu a pamwamba ndi mphamvu zolumikizirana pakati pa tinthu tating'onoting'ono ndi malo ozungulira. Zinthu monga kuyenda kwa Brownian, mphamvu za Van der Waals, ndi kuponderezedwa kwa electrostatic zimakhudza kwambiri kukhazikika kwawo, reactivity, ndi khalidwe lolekanitsidwa.

II. Udindo wa Centrifugation mu Kupatukana kwa Colloid:

1. Kutsegula Centrifugation: Chidule cha Njira Yogwiritsira Ntchito

Kugawa zinthu pogwiritsa ntchito centrifugation ndi njira yogwiritsidwa ntchito kwambiri yogawa zinthu pogwiritsa ntchito mphamvu ya centrifugal kuti zilekanitse zinthu kutengera kuchuluka ndi kukula kwake. Mwa kupotoza chitsanzo pa liwiro lalikulu, tinthu tolemera timagwera pansi pomwe zinthu zopepuka zimakhalabe zopachikidwa kapena kupanga zigawo zosiyana.

2. Kusiyanitsa Tinthu Tomwe Tili ndi Colloidal ndi Tinthu Tomwe Tili ndi Mantha

Ma Colloid ndi tinthu tomwe timapachikidwa, zomwe nthawi zambiri zimasokonezedwa ndi zina, zimafuna magawo osiyanasiyana a centrifugation kuti zipachikidwa bwino. Tinthu topachikidwa ndi tating'onoting'ono kwambiri ndipo tingalekanitsidwe mosavuta pogwiritsa ntchito njira zachikhalidwe zopachikidwa ndi madzi olimba. Kumbali inayi, ma colloid amafunika kukonza bwino magawo a centrifugation chifukwa cha kukula kwawo kochepa komanso kukhazikika kwawo.

III. Njira Zogwiritsira Ntchito Centrifugation Polekanitsa Colloid:

1. Kusiyanitsa kwa Kuchepetsa Mphamvu: Zoyambira

Kusinthasintha kwa centrifugation kumaphatikizapo kuzungulira kotsatizana pa liwiro lowonjezera kuti tinthu tisiyanitsidwe ndi kukula kwake. Mwa kusintha nthawi ndi liwiro la kuzungulira kulikonse, tinthu tating'onoting'ono ta colloidal tingathe kuchotsedwa ku zinyalala zazikulu kapena zinthu zina.

2. Kuchepetsa mphamvu zamagetsi (Ultracentrifugation): Kufufuza mozama

Kugawa ma ultracentrifugation ndi njira yamphamvu yomwe imagwiritsidwa ntchito kulekanitsa tinthu tating'onoting'ono kuposa timene timapangidwa kudzera mu kugawa ma centrifugation osiyanasiyana. Pa liwiro lalikulu kwambiri, nthawi zambiri limapitirira ma revolutions 100,000 pamphindi, ma ultracentrifuge amatha kugawa tinthu ta colloidal kutengera kuchuluka kwawo, zomwe pamapeto pake zimapangitsa kuti pakhale njira yothandiza yogawa ma centrifugation.

IV. Zinthu Zomwe Zimakhudza Kugwiritsa Ntchito Bwino kwa Centrifugation:

1. Kugawa Kukula kwa Tinthu

Kugawa kwa tinthu tating'onoting'ono m'machitidwe a colloidal kumakhudza kwambiri magwiridwe antchito a centrifugation. Kugawa kocheperako kwa tinthu tating'onoting'ono n'kwabwino chifukwa kumachepetsa kusokonezana pakati pa tinthu tating'onoting'ono tosiyanasiyana, zomwe zimapangitsa kuti pakhale kulekanitsidwa koyera.

2. Mphamvu ya pH ndi Ionic

Mphamvu ya pH ndi ionic ya dongosolo la colloidal zimakhudza kukhazikika ndi kuyanjana pakati pa tinthu tating'onoting'ono. Kuyang'anira mosamala magawo awa kungachepetse kusonkhana ndikuthandizira kulekanitsidwa bwino panthawi ya centrifugation.

V. Kugwiritsa Ntchito Moyenera ndi Malingaliro Amtsogolo:

1. Mankhwala ndi Ukadaulo Wachilengedwe

Kutsegula mpweya m'thupi (centrifugation) kumachita gawo lofunika kwambiri mumakampani opanga mankhwala, zomwe zimathandiza kuti mapuloteni, tinthu tating'onoting'ono, ndi zinthu zina zotchedwa colloidal zisamalidwe bwino. Njira imeneyi imathandiza kukonza njira zoperekera mankhwala, kupanga mankhwala okhazikika, komanso kupanga njira zatsopano zochiritsira.

2. Makampani Ogulitsa Zakudya ndi Zakumwa

Kuchotsa mafuta m'thupi pogwiritsa ntchito njira yoyeretsera thupi (centrifugation) kumagwiritsidwa ntchito kwambiri mumakampani opanga zakudya ndi zakumwa, monga kuyeretsa madzi, kulekanitsa kirimu wa mkaka, ndi kuchotsa mafuta kuchokera ku mbewu. Kulekanitsa bwino kwa colloidal kumathandiza kupanga zinthu zabwino kwambiri komanso kuchepetsa kuwononga.

Mapeto:

Ma Colloid amapezeka paliponse m'miyoyo yathu ya tsiku ndi tsiku, ndipo kulekanitsidwa kwawo kudzera mu centrifugation ndikofunikira m'mafakitale osiyanasiyana. Kumvetsetsa mfundo zomwe zili kumbuyo kwa kukhazikika kwa colloidal, kugwiritsa ntchito njira zoyenera zoyezera centrifugation, ndi kuganizira zinthu zosiyanasiyana zomwe zimakhudza ndikofunikira kwambiri kuti kulekanitsidwa kupambane.

Pamene ukadaulo ukupita patsogolo, tikhoza kuyembekezera chitukuko cha njira zatsopano zoyeretsera magetsi, zomwe zikuwongolera bwino komanso kudziwika bwino kwa njira zolekanitsira magetsi. Kafukufuku wa Colloidal akupitilizabe kukonza njira yopitira patsogolo m'magawo osiyanasiyana, ndikulonjeza tsogolo labwino kwa mafakitale omwe amadalira njira zolekanitsira zamagetsi.
