Ka'idar Colloid
Babban tasirin haifar da agglomeration na ƙwayoyin colloidal shine ƙarfin van der Waals tsakanin barbashi.Don ƙara kwanciyar hankali na ƙwayoyin colloidal, akwai hanyoyi guda biyu.Ɗayan shine ƙara haɓakar electrostatic tsakanin ƙwayoyin colloidal, ɗayan kuma shine don ƙirƙirar sarari tsakanin foda.Don hana agglomeration na powders a cikin wadannan hanyoyi biyu.
Tsarin colloidal mafi sauƙi ya ƙunshi wani lokaci mai tarwatsewa da matsakaici mai tarwatsewa, inda ma'aunin lokacin tarwatsa ya kasance daga 10-9 zuwa 10-6m.Abubuwan da ke cikin colloid dole ne su sami takamaiman matakin tarwatsawa don wanzuwa a cikin tsarin.Dangane da kaushi daban-daban da tarwatsewar matakai, ana iya samar da nau'ikan colloidal da yawa.Misali, hazo iskar iska ce wacce ɗigon ruwa ke tarwatsewa a cikin iskar gas, sannan man goge baki shine sol wanda ƙwararrun ƙwayoyin polymer suka tarwatse a cikin ruwa.
