Umbala we-iron oxide oluhlaza kanye ne-iron oxide ophuzi uyahluka enqubweni yokukhiqiza
I-iron oxide eluhlaza kanye ne-iron oxide ephuzi yimibala eyakhiwe ngama-ion ensimbi nama-ion oksijini. Kunomehluko othile ngemibala yazo phakathi nenqubo yokukhiqiza. Enqubweni yokukhiqiza ye-iron oxide eluhlaza, ihlanganiswa ikakhulukazi kusuka kuma-ion ensimbi nama-ion oksijini ngokusebenzisa ukusabela kwamakhemikhali. Ngokuvamile, umbala we-iron oxide oluhlaza ugcwele kakhulu, ubonakala uluhlaza okotshani noma oluhlaza okotshani. Phakathi nenqubo yokukhiqiza, ukujula kombala we-pigment kungalawulwa ngokulungisa izici ezifana nezimo zokusabela, ukugxila kwesixazululo, kanye nefomu le-oxide. Enqubweni yokukhiqiza ye-iron oxide ephuzi, ukusabela kwamakhemikhali kuyasetshenziswa futhi ukuze kuhlanganiswe ama-ion ensimbi nama-ion oksijini. Umbala we-iron oxide ophuzi ngokuvamile uphuzi ngokukhanyayo, ophuzi ngokugqamile noma osawolintshi. Uma kuqhathaniswa ne-iron oxide eluhlaza, i-iron oxide ephuzi ilula ngombala futhi ikhanya kancane. Kafushane, umehluko phakathi kwemibala ye-iron oxide eluhlaza kanye ne-iron oxide ephuzi phakathi nenqubo yokukhiqiza ibonakala ngokuyinhloko ekugcwalisweni nasekujuleni kombala kombala. Inqubo ethile yokukhiqiza kanye nezinyathelo zokulungisa zizoba nomthelela embala, futhi umbala we-pigment ungalawulwa ngezindlela ezifanele.
