tinthu ta colloid tomwe timabalalika tingasiyane mu centrifuge

Kodi Tinthu Tomwe Tili ndi Colloid Tomwe Tili ndi Dispersed Colloid Tingathe Kupatukana mu Centrifuge?

Chiyambi:

Ma Colloid ndi mtundu wapadera wa zinthu zomwe tinthu tating'onoting'ono timafalikira mofanana mu sing'anga, zomwe zimapangitsa kuti pakhale chisakanizo chokhazikika. Zitsanzo za ma colloid ndi monga gelatin, mkaka, ndi kirimu wokwapulidwa. Kulekanitsa tinthu ta colloid tomwe timafalikira kuchokera ku sing'anga kungakhale kovuta chifukwa cha kukula kwake kochepa komanso kufalikira kofanana. M'nkhaniyi, tifufuza ngati centrifugation ingalekanitse bwino tinthu ta colloid tofalikira ndikukambirana zofooka zake ndi momwe tingagwiritsire ntchito.

Kumvetsetsa Tinthu ta Colloid:

Tinthu ta Colloid timasiyana kukula kuyambira nanometers mpaka micrometers. Tilipo mu mkhalidwe wogawanika, kusunga mgwirizano wokhazikika chifukwa cha mphamvu zokopa komanso zonyansa zomwe zimagwira ntchito pakati pawo. Mphamvu zimenezi zimaletsa tinthu ta Colloid kuti tisakhazikike mwachilengedwe. Ngakhale kuti mphamvu yokoka ingayambitse kulekana pang'ono pakapita nthawi, sizingakhale zothandiza pazinthu zamafakitale zomwe nthawi ndi yofunika kwambiri.

Udindo wa Centrifuge:

Sentifuge ndi chipangizo cha labotale chomwe chimagwiritsa ntchito mphamvu ya centrifugal kulekanitsa tinthu tating'onoting'ono kutengera kukula, mawonekedwe, ndi kuchulukana kwawo. Mwa kuzungulira mofulumira, sentifuge imatsanzira mphamvu yokoka yamphamvu kwambiri kuposa mphamvu yokoka ya Dziko Lapansi, zomwe zimapangitsa kuti tinthu tating'onoting'ono tisiyane mwachangu. Koma kodi sentifuge ingalekanitse bwino tinthu ta colloid tomwe tafalikira?

Njira Yoyendetsera Centrifugation

Pamene chisakanizo cha colloid chiyikidwa mu centrifuge, chimayamba kuzungulira mofulumira. Mphamvu ya centrifugal imagwira ntchito mozungulira kunja ndipo imapanga mphamvu ya kupanikizika mkati mwa chisakanizocho. Mphamvu ya kupanikizika kumeneku imakankhira tinthu tomwe tabalalika kumphepete kwakunja kwa chubu cha centrifuge, zomwe zimapangitsa kuti pakhale dothi. Kuthamanga kwa mphamvu kumakhazikika mkati mwa chitsanzo, zomwe zimapangitsa kuti tinthu tambirimbiri tikhazikike mwachangu kuposa tinthu tating'onoting'ono.

Zofooka za Centrifugation

Ngakhale kuti centrifugation ndi njira yamphamvu yolekanitsira tinthu tating'onoting'ono, ili ndi zofooka zake pankhani ya tinthu tating'onoting'ono ta colloid tomwe timafalikira. Chovuta chachikulu ndi kukula kochepa kwa tinthu tating'onoting'onoti. Chifukwa cha kukula kwake kochepa, kuyenda kwa Brownian kumakhala kofunikira, zomwe zimapangitsa kuti tinthu tating'onoting'ono tizikhala nthawi yayitali ndikuchepetsa mphamvu ya sedimentation. Kuphatikiza apo, mphamvu zamagetsi pamalo a tinthu tating'onoting'ono zimatha kulepheretsa kusonkhana ndi kukhazikika.

Kugonjetsa Mavuto

Pofuna kuthana ndi mavuto okhudzana ndi kulekanitsa tinthu tating'onoting'ono ta colloid tomwe tafalikira, ofufuza afufuza zosintha zosiyanasiyana pa njira zachikhalidwe zoyendetsera centrifugation. Njira imodzi imaphatikizapo kuwonjezera ma coagulants kapena ma flocculants kuti alimbikitse kusonkhana kwa tinthu, ndikuwonjezera njira yoyendetsera matope. Njira ina ndikugwiritsa ntchito ultracentrifugation, pogwiritsa ntchito liwiro lapamwamba kwambiri komanso mapangidwe apamwamba a rotor kuti apange mphamvu zamphamvu zoyendetsera centrifugal.

Njira Zolimbikitsira Kutsegula Ma Centrifugation

Kupatula ma coagulants ndi ultracentrifugation, asayansi apanga njira zina zowonjezera kulekanitsa tinthu ta colloid tomwe tafalikira. Zipangizo za microfluidic, mwachitsanzo, zimagwiritsa ntchito njira zazing'ono ndi mphamvu za centrifugal kuti zithandize njira yolekanitsira tinthu. Njira zopangidwa bwino zimapanga kuyenda kwa laminar, zomwe zimapangitsa kuti tinthu ta colloidal tichotsedwe bwino kwambiri.

Mapulogalamu a Mafakitale

Kutsegula madzi m'malo osungiramo zinthu (centrifugation) kumagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana. Mu makampani opanga zakudya ndi zakumwa, kumathandiza kulekanitsa zinyalala kapena tinthu tolimba ndi zakumwa, zomwe zimapangitsa kuti zinthu zikhale bwino kwambiri. Makampani opanga mankhwala amadalira kuyeretsa ndi kupatula tinthu tomwe timafunikira panthawi yopanga mankhwala. Kuphatikiza apo, malo oyeretsera madzi otayira amagwiritsa ntchito ma centrifuge kuti achotse bwino zinthu zolimba zomwe zapachikidwa ndi zinthu zina zoipitsa madzi m'madzi, zomwe zimathandiza kuti malo azikhala oyera.

Mapeto:

Ngakhale tinthu tating'onoting'ono ta colloid tomwe timabalalika timayambitsa mavuto pa centrifugation, ofufuza apita patsogolo kwambiri popanga njira zowonjezerera kulekanitsa kwawo. Kusintha ma centrifuge achikhalidwe, kuphatikiza ma coagulants, ndi kufufuza zida zazing'onoting'ono ndi zitsanzo zochepa chabe za kupita patsogolo komwe kukuchitika. Mwa kumvetsetsa zofooka ndi kufufuza njira zatsopano, asayansi amatha kutsegula kuthekera konse kwa centrifugation yolekanitsa tinthu ta colloid tobalalika, ndikusinthiratu mafakitale osiyanasiyana panthawiyi.
