Colloids: Nhanganyaya Yakadzama
Colloid isystem yakasiyana-siyana ine zvinhu zviviri kana kupfuura umo zvidimbu zvidiki zvechinhu chimwe zvinopararira zvakaenzana kune chimwe. Zvikamu izvi, zvinozivikanwa sechikamu chakapararira, zvinofamba nepakati penzvimbo yekupararira. Colloids inoita basa rakakosha muzvikamu zvakasiyana-siyana, kubva kubiology, chemistry, uye physics kusvika kune tekinoroji nemishonga.
Maumbirwo eColloid uye Kurongwa
Makororodhi ane zvikamu zviviri zvikuru: chikamu chakapararira uye chikamu chinopararira. Chikamu chakapararira chinogona kuva chakasimba, chemvura, kana chegasi, nepo chikamu chinopararira chinogona kuva chakafanana. Kubatanidzwa kwezvikamu izvi kunoburitsa mhando dzakasiyana dzemakororodhi, ayo anorongwa zvichienderana nechikamu chawo.
Mhando dzeColloids Dzinoenderana nePaseji
1. Aerosol: Inogadzirwa kana zvidimbu zvakaoma kana zvemvura zvakapararira mugasi.
– Muenzaniso: Utsi (hwakasimba mugasi), mhute (mvura mugasi).
2. Emulsion: Sisitimu umo mvura inoparadzirwa mune imwe mvura.
– Muenzaniso: Mukaka (mafuta mumvura), mayonnaise (mafuta mumvura).
3. Zvimedu: Zvimedu zvakaoma zvakapararira mumvura.
– Mienzaniso: Pendi, inki, mushonga wegoridhe wecolloidal.
4. Gel: Sisitimu yakaoma zvishoma umo zvidimbu zvemvura zvinobatwa mukati mechimiro chakasimba.
– Mienzaniso: Jeli, agar-agar.
5. Furo: Gasi rakapararira mumvura kana kuti rakaoma.
– Mienzaniso: Furo resipo (gasi riri mumvura), marshmallows (gasi riri muchinhu chakaoma).
Kunyangwe mhando dzakasiyana dzemacolloid dzichiumbwa zvichienderana nechikamu chakapararira uye nzvimbo inopararira, chinangwa chikuru chinogara chiri pakugoverwa uye mafambiro ezvikamu muzvikamu zvakasiyana.
Hunhu hweColloids
Mhedzisiro yeTyndall
Mhedzisiro yeTyndall chiitiko umo chiedza chinopararira nezvidimbu zvecolloidal pachinopfuura nepakati penzvimbo dzakasiyana. Mhedzisiro iyi inoita kuti nzira yemwaranzi yechiedza ionekwe mumisanganiswa yecolloidal. Mhedzisiro yeTyndall inoshandiswa kusiyanisa mhinduro dzechokwadi kubva kumasisitimu ecolloidal.
Kufamba kweBrownian
Kufamba kwebrownian kufamba kwecolloidal particles muchikamu chekupararira. Chiitiko ichi chinokonzerwa nekusangana kusina kurongeka pakati pezvikamu zvecolloidal nemamorekuru echikamu chekupararira. Kufamba kwebrownian kunobatsira kuchengetedza kugadzikana kwecolloid nekudzivirira kudonha kwezvikamu.
Kunyungudutsa
Zvidimbu zveColloidal zvine nzvimbo yakakura uye zvinogona kunyudza mamorekuru pamusoro pazvo. Kunyudza kunogona kukanganisa kugadzikana kwecolloidal. Semuenzaniso, maion kana mamorekuru anonyudzwa anogona kudzikamisa kushaikwa kwemagetsi pamusoro pezvikamu zvecolloidal, zvichidzivirira kuvharika kana kuungana kwezvikamu.
Kushandiswa kweElectrophoresis
Electrophoresis kufamba kwezvikamu zvecolloidal mumunda wemagetsi. Zvikamu zvine chaji zvinofamba zvichienda kumaelectrodes ane chaji dzakasiyana. Iyi nzira inoshandiswa mukuparadzanisa uye kutsanangura hunhu hwezvikamu zvecolloidal.
Kushandiswa kweColloids muhupenyu hwezuva nezuva
Indasitiri yezvekudya
MaColloid akakosha muindasitiri yezvekudya, semuenzaniso mukugadzira zvigadzirwa zvemukaka, masosi, uye emulsions. MaEmulsion akadai semayonnaise nebhota mienzaniso apo kugadzikana kwecolloid kunosarudza kunaka kwechigadzirwa.
Pharmacy uye Mishonga
Muindasitiri yemishonga, macolloid anoshandiswa kugadzira mishonga inomiswa uye inogadziriswa inovandudza kunyungudika uye kuwanikwa kwezvinhu zvinoshanda. Masisitimu ekutumira mishonga anobva kuColloid anobatsirawo mukuendesa mishonga zvakananga kumasero kana tishu dzakananga.
zvizoro
Zvigadzirwa zvekushongedza zvakaita semafuta ekuzora, makirimu, nesipo mienzaniso yekushandiswa kwecolloid. Mafomu eColloidal anobatsira kugovera zvinhu zvinoshanda zvakaenzana uye kuwedzera kushanda zvakanaka uye kupinza chigadzirwa.
Uinjiniya hweKutarisira Zvakatipoteredza
MaColloid anobatanidzwa mukuchenesa mvura uye nzira dzekurapa mvura yakasviba. Semuenzaniso, kugona kunyungudutsa kwezvikamu zvecolloidal kunobatsira mukubvisa tsvina ye organic ne inorganic mumvura. Nzira dzeColloid-based coagulation uye flocculation dzinoshandiswawo muindasitiri yekurapa mvura yakasviba.
Tekinoroji yeNanotechnology
Mu nanotechnology, ma colloid anoita basa rakakosha mukugadzirwa nekushandiswa kwema nanoparticles. Ma nanoparticles anoparadzirwa mu colloidal media anoshandiswa zvakanyanya muzvinhu, zvemagetsi, uye biomedicine.
Matambudziko Nemikana Yeramangwana
Kugadzikana kweColloidal
Chimwe chezvinetso zvikuru mukutsvagurudza kwecolloid kuchengetedza kugadzikana kwadzo. Zvidimbu zvecolloidal zvinowanzo kuungana kana kudonha kubva mumhinduro dzecolloidal. Kunzwisisa kwakadzama mashandiro ekudyidzana kwemasero pamwe nekushandiswa kwezvinosimbisa kana masurfactants zvinobudirira ndizvo zvakakosha pakukunda dambudziko iri.
Colloids muBiopharmaceuticals
Kugadzirwa kwe colloids mu biopharmaceuticals kunopa mikana yakakura, semuenzaniso, mukugadzirwa kwenzira dzakanyatsojeka uye dzinoshanda dzekupa mishonga. Matambudziko makuru ndeekudzora saizi yezvidimbu uye simba repamusoro, zvese izvi zvinokanganisa kunangwa uye reactivity ye colloidal systems mumuviri.
Colloids muZvishandiso Zvitsva
MaColloid ane zvakanakira zvakasiyana mukugadzirwa kwezvinhu zvitsva, zvakaita semasensa, macatalyst, nezvinhu zvinochengetedza simba. Tsvakurudzo yakawedzerwa inotarisirwa kugadzira zvinhu zvecolloidal zvine mabasa uye hunhu hwazvo hunodzorwa.
Mhedziso
MaColloid masisitimu akaomarara asi akakosha ane mashandisirwo akawanda muhupenyu hwezuva nezuva nemaindasitiri. Hunhu hwavo hwakasiyana, hwakadai seTyndall effect, Brownian motion, adsorption, uye electrophoresis, hunopa mikana yakakura yekutsvaga nekuvandudza tekinoroji. Kunzwisisa chimiro, hunhu, uye mashandisirwo emacolloid ndiyo nhanho yekutanga mukushandisa kugona kwakazara kwechiitiko ichi.
Nekufambira mberi kwetekinoroji uye kunzwisisa kwesainzi kuri kuramba kuchiwedzera, ramangwana remakororodhi rinotaridzika zvakanaka, netariro dzekuvandudza zvinhu zvakasiyana-siyana muminda yakasiyana-siyana. Kuenderera mberi nekutsvaga nekushandira pamwe pakati peminda yakasiyana-siyana kuchaita basa guru mukugadzirisa matambudziko uye kuona kugona kwemakororodhi munyika yanhasi.
Chinyorwa chino chinangwa ndechekupa vaverengi kunzwisisa kwakadzama kwepfungwa huru, hunhu, uye mashandisirwo akasiyana-siyana e colloids. Kunzwisisa uku kwakawedzerwa kwe colloids kuchavhura mukana wekuwana zvinhu zvitsva uye zvitsva mune ramangwana.
