Colloids: Gabatarwa Mai Zurfi
Colloid tsari ne mai bambanci wanda ya ƙunshi abubuwa biyu ko fiye waɗanda ƙananan ƙwayoyin cuta na abu ɗaya ke warwatse a cikin ɗayan. Waɗannan ƙwayoyin cuta, waɗanda aka sani da yanayin warwatse, suna ratsa ta cikin hanyar warwatsewa. Colloids suna taka muhimmiyar rawa a fannoni daban-daban, tun daga ilmin halitta, sinadarai, da kimiyyar lissafi zuwa fasaha da magani.
Tsarin da Rarraba Colloid
Colloids sun ƙunshi manyan sassa guda biyu: matakin da aka watsa da kuma matsakaicin watsawa. Matakin da aka watsa na iya zama mai ƙarfi, ruwa, ko iskar gas, yayin da matsakaicin watsawa na iya zama iri ɗaya. Haɗin waɗannan matakai yana samar da nau'ikan colloids daban-daban, waɗanda aka rarraba bisa ga matakinsu.
