Iron oxide pigment imagwiritsidwa ntchito kwambiri popaka, utoto, ndi inki chifukwa chosakhala ndi poizoni, osataya magazi, otsika mtengo, komanso amatha kupanga mithunzi yosiyanasiyana.Zovala zimapangidwa ndi zinthu zopanga filimu, ma pigment, fillers, solvents, ndi zowonjezera.Zapangidwa kuchokera ku zokutira zokhala ndi mafuta mpaka zokutira zopangira utomoni, ndipo zokutira zosiyanasiyana sizingachite popanda kugwiritsa ntchito utoto, makamaka ma pigment a iron oxide, omwe asanduka mitundu yofunikira kwambiri pamakampani opaka utoto.

Iron oxide inki yomwe imagwiritsidwa ntchito popaka utoto imaphatikizapo chitsulo chachikasu, chofiyira chachitsulo, chofiirira chachitsulo, chakuda chachitsulo, mica iron oxide, chitsulo chowoneka bwino chachikasu, chofiyira chachitsulo chowoneka bwino, ndi zinthu zowoneka bwino, zomwe chitsulo chofiira ndichofunika kwambiri mochulukirapo komanso mosiyanasiyana. .
Chitsulo chofiira chimakhala ndi kukana kutentha kwambiri, sichimasintha mtundu pa 500 ℃, ndipo sichisintha kapangidwe kake ka mankhwala pa 1200 ℃, ndikupangitsa kuti ikhale yokhazikika kwambiri.Imatha kuyamwa kuwala kwa ultraviolet mu kuwala kwa dzuwa, kotero imakhala ndi mphamvu zoteteza pa zokutira.Simamva kusungunuka kwa asidi, alkalis, madzi, ndi zosungunulira, zomwe zimapangitsa kuti zisawonongeke nyengo.

The Granularity of iron oxide red ndi 0.2 μ M, malo enieni komanso kuyamwa kwamafuta kulinso kwakukulu.Granularity ikachulukira, mtunduwo umachokera kugawo lofiirira, ndipo malo enieni komanso kuyamwa kwamafuta kumakhala kochepa.Iron red imagwiritsidwa ntchito kwambiri popaka dzimbiri ndi anti dzimbiri.Chinyezi m'mlengalenga sichingalowe muzitsulo zachitsulo, ndipo zimatha kuonjezera kachulukidwe ndi mphamvu zamakina za zokutira.
Mchere wonyezimira wachitsulo wonyezimira wachitsulo womwe umagwiritsidwa ntchito mu utoto wotsutsa dzimbiri uyenera kukhala wotsika, womwe umapindulitsa pakuwongolera magwiridwe antchito a dzimbiri, makamaka ma ion chloride akawonjezeka, madzi ndi osavuta kulowa mu zokutira, ndipo nthawi yomweyo, imathandiziranso kuwonongeka kwachitsulo. .

Chitsulo chimakhudzidwa kwambiri ndi asidi, kotero pamene mtengo wa PH wa utomoni, pigment kapena zosungunulira mu utoto uli pansi pa 7, n'zosavuta kulimbikitsa zitsulo.Pambuyo poyang'ana dzuwa kwa nthawi yayitali, utoto wofiira wachitsulo umakhala wonyezimira, makamaka chitsulo chofiira ndi Granularity yaying'ono ndi ufa mofulumira, kotero kuti chitsulo chofiira ndi Granularity yaikulu chiyenera kusankhidwa kuti chiwongolere nyengo, koma ndi zophweka. kuchepetsa gloss wa zokutira.

Kusintha kwa mtundu wa topcoat nthawi zambiri kumachitika chifukwa cha kusuntha kwa gawo limodzi kapena zingapo za pigment.Kusanyowa kwa pigment ndi zinthu zambiri zonyowetsa nthawi zambiri ndizomwe zimayambitsa kuyandama.Pambuyo calcination, pigment ali kwambiri chizolowezi flocculation.Choncho, pofuna kuonetsetsa kuti yunifolomu ndi yosasinthasintha mtundu wa topcoat, ndi bwino kusankha chonyowa kaphatikizidwe wofiira chitsulo.Malo opaka opangidwa ndi singano ngati chitsulo chofiira ngati kristalo amatha kukhala ndi mercerization, ndipo mikwingwirima yomwe imapangidwa popenta imawonedwa kuchokera kumakona osiyanasiyana, ndi mitundu yosiyanasiyana yamitundu, ndipo imagwirizana ndi mawonekedwe osiyanasiyana a makristalo.

Poyerekeza ndi zinthu zachilengedwe, kupanga chitsulo okusayidi wofiira ali ndi kachulukidwe apamwamba, Granularity yaying'ono, chiyero chapamwamba, mphamvu yobisala bwino, kuyamwa kwakukulu kwamafuta ndi mphamvu zopaka utoto.M'mapangidwe ena a utoto, chitsulo chofiira chachitsulo chofiira chimagawidwa ndi zinthu zopangidwa, monga iron oxide red alkyd primer yomwe imagwiritsidwa ntchito popangira zinthu za Ferrous monga magalimoto, makina ndi zida.
