zvinogona kupatsanurwa zvidimbu zvecolloid zvakaparadzana mu centrifuge

Zvidimbu zveColloid Zvakapararira Zvinogona Kuparadzaniswa MuCentrifuge Here?

Nhanganyaya:

MaColloid imhando yakasiyana yezvinhu apo zvidimbu zvinopararira zvakaenzana mukati mechinhu, zvichigadzira musanganiswa wakasimba. Mienzaniso yecolloid inosanganisira gelatin, mukaka, uye whipped cream. Kuparadzanisa zvidimbu zvecolloid zvakapararira kubva kune chinhu kunogona kuoma nekuda kwehukuru hwazvo uye kupararira kwazvo. Muchinyorwa chino, tinoongorora kana centrifugation inogona kuparadzanisa zvidimbu zvecolloid zvakapararira zvinobudirira uye tinokurukura miganhu yayo uye mashandisirwo ayo anogona kuitwa.

Kunzwisisa Colloid Particles:

Zvidimbu zveColloid zvinosiyana-siyana muhukuru kubva kuma nanometers kusvika kuma micrometers. Zviripo muchimiro chakapararira, zvichichengetedza kuenzana kwakasimba nekuda kwemasimba anokwezva uye anosemesa anoshanda pakati pazvo. Masimba aya anodzivirira zvidimbu kuti zvisagadzikane zvakasikwa. Kunyange zvazvo simba rinokwevera pasi richigona kukonzera kupatsanurwa kwechikamu nekufamba kwenguva, zvingasave zvinobatsira kumaindasitiri apo nguva iri chinhu chakakosha.

Basa reCentrifuge:

Centrifuge mudziyo wemurabhoritari unoshandisa simba recentrifugal kuparadzanisa zvidimbu zvichienderana nehukuru hwazvo, chimiro, uye huwandu hwazvo. Nekutenderera nekumhanya kwakanyanya, centrifuge inotevedzera simba regiravhiti rakasimba kupfuura simba repasi, zvichibvumira kupatsanurwa kwezvidimbu nekukurumidza. Asi centrifuge inogona here kuparadzanisa zvidimbu zvecolloid zvakapararira zvinobudirira?

Nzira yeCentrifugation

Kana musanganiswa wecolloid ukaiswa mu centrifuge, unotanga kutenderera nekukurumidza. Simba re centrifugal rinoshanda ne radially kunze uye rinogadzira pressure gradient mukati memusanganiswa. Iyi pressure gradient inosundira zvidimbu zvakapararira kumucheto wekunze kwechubhu ye centrifuge, zvichiita kuti pave ne sedimentation. Velocity gradients inogadzwa mukati memuenzaniso, zvichiita kuti zvidimbu zvakakura zvigare nekukurumidza kupfuura zvidimbu zvidiki.

Miganhu yeCentrifugation

Kunyange hazvo centrifugation iri nzira ine simba yekuparadzanisa zvidimbu, ine zvipingamupinyi zvayo kana zvasvika kune zvidimbu zvecolloid zvakapararira. Chinonetsa chikuru ihukuru hudiki hwezvidimbu izvi. Nekuda kwehukuru hwazvo hudiki, kufamba kweBrownian kunova kwakakosha, zvichiita kuti zvidimbu zvirambe zvakamira kwenguva yakareba uye zvichideredza kushanda kwe sedimentation. Pamusoro pezvo, ma electrostatic charges pamusoro pezvikamu anogona kukanganisa kuungana uye kugara zvakanaka.

Kukunda Matambudziko

Kuti vakunde matambudziko ane chekuita nekuparadzanisa zvidimbu zvecolloid zvakapararira, vaongorori vakaongorora shanduko dzakasiyana-siyana dzemaitiro echinyakare e centrifugation. Imwe nzira inosanganisira kuwedzera ma coagulants kana flocculants kukurudzira kuunganidzwa kwezvikamu, zvichivandudza maitiro e sedimentation. Imwe nzira ndeyekushandisa ultracentrifugation, uchishandisa kumhanya kwakanyanya uye magadzirirwo e rotor epamusoro kugadzira masimba akasimba e centrifugal.

Maitiro Akavandudzwa eCentrifugation

Kunze kwezvinobatanidza macoagulants uye ultracentrifugation, masayendisiti akagadzira dzimwe nzira dzekuwedzera kupatsanurwa kwezvikamu zvecolloid zvakapararira. Midziyo yemicrofluidic, semuenzaniso, inoshandisa migero midiki uye masimba ecentrifugal kuti zvive nyore kupatsanurwa kwezvikamu. Migero yakagadzirwa nemazvo inogadzira kuyerera kwelaminar, ichiparadzanisa zvikamu zvecolloidal kubva pakati pezvinhu zvinobudirira.

Zvikumbiro zveMaindasitiri

Kugadzira simbi yekuchenesa mvura (centrifugation) kunoita basa guru mumaindasitiri akasiyana-siyana. Muindasitiri yezvikafu nezvinwiwa, kunobatsira kuparadzanisa tsvina kana zvidimbu zvakasimba kubva mumvura, zvichiita kuti chigadzirwa chive chemhando yepamusoro. Makambani emishonga anovimba nekushandisa simbi yekuchenesa nekubvisa zvidimbu zvinodiwa panguva yekugadzira mishonga. Uyezve, nzvimbo dzekuchenesa mvura yakasviba dzinoshandisa simbi yekuchenesa mvura kuti dzibvise zvinhu zvakaoma zvakamiswa nemvura zvinobudirira, zvichibatsira kuti nharaunda dzive dzakachena.

Mhedziso:

Kunyangwe zvimedu zvecolloid zvakapararira zvichikonzera matambudziko pakushanda kwemasero, vaongorori vakaita kufambira mberi kukuru mukugadzira matekiniki ekuvandudza kupatsanurwa kwazvo. Kugadzirisa macentrifuge echinyakare, kuisa macoagulants, uye kuongorora michina ye microfluidic inongova mienzaniso mishoma yekufambira mberi kuri kuitwa. Nekunzwisisa zvipingamupinyi uye kutsvaga nzira itsva, masayendisiti anogona kuvhura mukana wakazara wekushanda kwemasero ekuparadzanisa zvimedu zvecolloid zvakapararira, zvichichinja maindasitiri akasiyana-siyana ari kuita izvi.
