I-iron oxide pigment luhlobo lwe-pigment ene-dispersibility elungileyo, ukumelana nokukhanya okugqwesileyo, kunye nokumelana nemozulu.I-iron oxide pigments ibhekisela ikakhulu kwiindidi ezine zemibala ye-pigments, ezizezi, i-iron oxide ebomvu, i-iron emthubi, i-iron emnyama, kunye ne-iron brown, esekelwe kwi-iron oxides.Phakathi kwazo, i-iron oxide ebomvu yeyona pigment iphambili (ibalelwa malunga ne-50% ye-iron oxide pigments), kunye ne-mica iron oxide esetyenziswa njenge-anti-rust pigments kunye ne-iron oxide yamagnetic esetyenziswa njengezixhobo zokurekhoda zemagneti nazo ziyinxalenye ye-iron oxide pigments.I-iron oxide yeyesibini ngobukhulu i-pigment ye-inorganic emva kwe-titanium dioxide kunye ne-pigment enkulu enemibala.Ngaphezulu kwe-70% yazo zonke ii-pigments ze-iron oxide ezisetyenzisiweyo zilungiswa ngeendlela ze-chemical synthesis, ezaziwa ngokuba yi-synthetic iron oxide.I-Synthetic iron oxide isetyenziswa ngokubanzi kwiinkalo ezifana nezixhobo zokwakha, iingubo, iiplastiki, i-electronics, icuba, amayeza, irabha, i-ceramics, i-inki, izinto eziphathekayo, i-papermaking, njl. imibala emininzi, ixabiso eliphantsi, iipropathi ezingenayo ityhefu, umbala obalaseleyo kunye nokusebenza kwesicelo, kunye nokusebenza kokufunxa kwe-UV.
Ukusetyenziswa kwe-iron oxide pigments kwimveliso yekhonkrithi iya ixhaphake kakhulu, kwaye ukusetyenziswa kwe-iron oxide ebomvu kwiimveliso zekhonkrithi kufuneka kuhlawule ingqalelo kwezi zalathisi zilandelayo.1. Khetha umbala omhle.Kukho amanqanaba amaninzi e-iron oxide ebomvu, kwaye imibala iyahluka ukusuka ekukhanyeni ukuya kubunzulu.Okokuqala, khetha umbala owanelisayo ngawo.2. Ukongeza i-pigments kwiimveliso zekhonkrithi kunokuba nefuthe kumandla ekhonkrithi.Ukongezwa ngakumbi, ngakumbi kuya kuchaphazela amandla ekhonkrithi.Ngoko umgaqo kukunciphisa inani le-pigment elongezelelweyo kangangoko kunokwenzeka.Okungcono amandla ombala we-pigment, encinci yongezwa.Ke okukhona iphezulu imfuno yamandla ombala wee-pigments, kokukhona kungcono.3. I-iron oxide ebomvu yenziwe nge-oxidation yezikali zentsimbi kwimidiya ye-acidic.Ukuba ii-pigments ezikumgangatho ophantsi zine-acidic kancinane, i-pigments ene-acidic iya kusabela ngesamente ye-alkaline ukuya kwinqanaba elithile, ngoko ke i-acidity ephantsi ye-iron oxide ebomvu, ingcono.
Ifomula ye-iron oxide pigment iyimfuneko ekhethekileyo kwiingubo zanamhlanje kunye namashishini e-thermoplastic.
Le mveliso ifanelekile kwiinkqubo eziqhelekileyo ezisekelwe kwi-solvent kunye neengubo ezisekelwe emanzini.Ukufunxwa kweoli ephantsi kuphunyezwa ngenkqubo ekhethekileyo yokugaya, evelisa ukusabalalisa ubungakanani be-particle encinci kwaye phantse i-spherical (polygonal).Ukufunxwa kwe-oyile ephantsi ngumlinganiselo obalulekileyo wokwenza iileyiti eziphezulu eziqinileyo kunye neenkqubo zokudaya eziqinileyo zesiqulatho esiphakamileyo kunye nee-inki zezinto eziguquguqukayo zezinto eziphilayo.Kucetyiswa ukuba ube nomxholo wetyuwa onyibilikayo ophantsi kakhulu wamanzi, njengoko i-iron oxide pigments inokuqina okuphezulu kunye nokumelana nemozulu entle.
I-depolymerized iron oxide pigment eyenziwe ngonyango lobushushu kwaye ngoko imele i-thermal calcined iron oxide ebomvu.
Ii-pigments zineenzuzo ezibalulekileyo xa kuthelekiswa nezinto eziqhelekileyo zokwenziwa.
