Su'aalo iyo Doodo Tusaalo ah oo ku saabsan Noocyada Colloids-ka
Pendahuluan
Colloid waa nidaam ka kooban laba marxaladood: marxalad kala firdhisan iyo marxalad kala firdhisan. Marxaladda kala firdhisan waa walxaha cabbirka colloidal-ka ah (1-1000 nm), halka marxaladda kala firdhisan ay tahay habka ay walxaha kala firdhisan yihiin. Colloids-ku waxaa si joogto ah loola kulmaa nolol maalmeedka waxaana lagu bartaa kiimikada sababtoo ah waxay leeyihiin sifooyin gaar ah oo ka soocaya xalalka dhabta ah iyo joojinta. Maqaalkan, waxaan ka hadli doonnaa noocyo badan oo colloids ah iyadoo lagu saleynayo marxaladahooda kala firdhisan iyo kuwa kala firdhisan, iyo sidoo kale dhibaatooyinka tusaalaha ah iyo doodaha si loo caddeeyo fikraddan.
