Umbala we-iron oxide eluhlaza kunye ne-iron oxide etyheli iyahluka kwinkqubo yokuvelisa
I-iron oxide eluhlaza kunye ne-iron oxide etyheli zizibala ezenziwe nge-iron ion kunye ne-oxygen ion. Kukho umahluko kwimibala yabo ngexesha lenkqubo yokuvelisa. Kwinkqubo yokuvelisa i-iron oxide eluhlaza, idityaniswe ikakhulu kwi-iron ion kunye ne-oxygen ion ngokusebenzisa iikhemikhali. Ngokubanzi, umbala we-iron oxide eluhlaza ugcwele, ubonakala uluhlaza mnyama okanye uluhlaza omnyama. Ngexesha lenkqubo yokuvelisa, ubunzulu bombala webala bungalawulwa ngokuhlengahlengisa izinto ezifana neemeko zokusabela, ukuxinana kwesisombululo, kunye nefom ye-oxide. Kwinkqubo yokuvelisa i-iron oxide etyheli, ukuphendula kweekhemikhali kukwasetyenziselwa ukudibanisa i-iron ion kunye ne-oxygen ion. Umbala we-iron oxide emthubi udla ngokuba lutyheli olukhanyayo, olutyheli oluqaqambileyo okanye oluorenji. Xa ithelekiswa ne-iron oxide eluhlaza, i-iron oxide emthubi ikhaphukhaphu ngombala kwaye icace ngakumbi. Isishwankathelo, umahluko phakathi kwemibala ye-iron oxide eluhlaza kunye ne-iron oxide etyheli ngexesha lenkqubo yokuvelisa ibonakaliswa ikakhulu kwi-saturation kunye nobunzulu bombala we-pigment. Inkqubo ethile yokuvelisa kunye nemilinganiselo yokulungelelanisa iya kuba nefuthe kumbala, kwaye umbala we-pigment unokulawulwa ngeendlela ezifanelekileyo.
