I-iron oxide pigment iwuhlobo lwe-pigment olunokuhlakazeka okuhle, ukumelana nokukhanya okuhle kakhulu, nokumelana nesimo sezulu.I-iron oxide pigments ikakhulukazi ibhekisela ezinhlotsheni ezine zombala wombala, okuyi-iron oxide ebomvu, ephuzi yensimbi, emnyama yensimbi, ne-iron brown, esekelwe kuma-iron oxides.Phakathi kwazo, i-iron oxide ebomvu iwumbala oyinhloko (okubala cishe u-50% we-iron oxide pigments), kanye ne-mica iron oxide esetshenziswa njenge-anti-rust pigments kanye ne-magnetic iron oxide esetshenziswa njengezinto zokuqopha kazibuthe nazo ziyingxenye ye-iron oxide pigments.I-iron oxide ingeyesibili ngobukhulu bombala we-inorganic ngemva kwe-titanium dioxide kanye ne-pigment enkulu kunazo zonke enombala.Ngaphezu kwama-70% azo zonke izikhala ze-iron oxide ezisetshenzisiwe zilungiswa ngezindlela zokuhlanganiswa kwamakhemikhali, ezaziwa ngokuthi i-synthetic iron oxide.I-synthetic iron oxide isetshenziswa kakhulu emikhakheni efana nezinto zokwakha, okokugqoka, amapulasitiki, i-electronics, ugwayi, imithi, irabha, izitsha zobumba, oyinki, izinto kazibuthe, ukwenza iphepha, njll. ngenxa yokuhlanzeka kwayo okuphezulu, usayizi wezinhlayiyana ezifanayo, i-chromatography ebanzi, imibala eminingi, izindleko eziphansi, izakhiwo ezingenabo ubuthi, umbala omuhle kakhulu nokusebenza kwesicelo, nokusebenza kokumuncwa kwe-UV.

Ukusetshenziswa kombala we-iron oxide wokufaka imibala kwemikhiqizo kakhonkolo kuya ngokuya kuvame, futhi ukusetshenziswa kwe-iron oxide ebomvu emikhiqizweni kakhonkolo kufanele kunake izinkomba ezilandelayo.1. Khetha umbala omuhle.Kunamabanga amaningi e-iron oxide ebomvu, futhi imibala isuka kokukhanya iye ekujuleni.Okokuqala, khetha umbala owanelisekile ngawo.2. Ukwengeza ama-pigments emikhiqizweni kakhonkolo kungaba nomthelela emandleni kakhonkolo.Okungeziwe okwengeziwe, kuzothinta kakhulu amandla okhonkolo.Ngakho-ke umgomo uwukunciphisa inani le-pigment elingeziwe ngangokunokwenzeka.Amandla ombala we-pigment angcono, awengezwa kancane.Ngakho-ke ukuphakama kwesidingo samandla ombala we-pigments, kungcono.3. I-iron oxide ebomvu yakheka ngokufakwa kwezikali zensimbi emithonjeni ene-asidi.Uma izingulube zekhwalithi ephansi zine-acidic kancane, ama-pigments ane-acidic azosabela ngosimende we-alkaline ngezinga elithile, ngakho-ke ukwehla kwe-asidi ye-iron oxide ebomvu, kungcono.

Ifomula ye-iron oxide pigment iyisidingo esikhethekile sezingubo zanamuhla nezimboni ze-thermoplastic.

Lo mkhiqizo ulungele izinhlelo ezijwayelekile ezisekelwe ku-solvent kanye nezingubo ezisekelwe emanzini.Ukumuncwa kwamafutha aphansi kufinyelelwa ngenqubo yokugaya ekhethekile, ekhiqiza ukusabalalisa usayizi wezinhlayiyana ezincane kanye nezinhlayiya ezicishe zibe yindilinga (polygonal).Ukumuncwa kukawoyela okuphansi kuyisilinganiso esibalulekile sokwenza okunamathelayo okuphezulu okuqinile kanye nezinhlelo zokudaya eziqinile zokuqukethwe okuqinile noyinki wezinhlanganisela zezinto eziphilayo eziguquguqukayo.Kunconywa ukuthi kube nosawoti oncibilikayo ophansi kakhulu emanzini, njengoba i-iron oxide pigments inokuqina okuphezulu kanye nokumelana nesimo sezulu esihle.

I-depolymerized iron oxide pigment yakhiwa ukwelashwa kokushisa futhi ngenxa yalokho imele i-iron oxide ebomvu eqinile eqinile.
Ama-pigments anezinzuzo ezibalulekile uma kuqhathaniswa nezinto ezivamile zokwenziwa.
