Kodi Iron Oxide Pigment ndi chiyani

Iron oxide pigments ndi zinthu zopangidwa kapena zachilengedwe zopangidwa ndi chitsulo ndi mpweya. Amagwiritsidwa ntchito kwambiri ngati zopaka utoto m'magwiritsidwe osiyanasiyana chifukwa cha kukhazikika kwawo, kulimba kwawo, komanso kusakhala ndi poizoni. Iron oxide pigments imabwera mumitundu yosiyanasiyana, kuphatikiza yofiira, yachikasu, bulauni, yakuda, kutengera mtundu wa mankhwala ndi njira zopangira.

Nazi mfundo zazikuluzikulu za pigment ya iron oxide:

1. Kapangidwe kake: Iron oxide pigments makamaka imakhala ndi iron oxides ndi oxyhydroxides. Mankhwala akuluakulu amaphatikizapo iron(II) oxide (FeO), iron(III) oxide (Fe2O3), ndi iron(III) oxyhydroxide (FeO(OH)).
2. Mitundu Yamitundu:
   • Red Iron Oxide (Fe2O3): Imadziwikanso kuti ferric oxide, red iron oxide ndiyomwe imagwiritsidwa ntchito kwambiri ndi iron oxide pigment. Amapereka mitundu yochokera ku lalanje-wofiira mpaka wofiira kwambiri.
   • Yellow Iron Oxide (FeO(OH)): Amatchedwanso yellow ocher kapena hydrated iron oxide, mtundu uwu umatulutsa mithunzi yachikasu mpaka yachikasu-bulauni.
   • Black Iron Oxide (FeO kapena Fe3O4): Mitundu yakuda ya iron oxide nthawi zambiri imagwiritsidwa ntchito popangitsa mdima kapena mthunzi.
   • Brown Iron oxide: Mtundu uwu nthawi zambiri umakhala ndi kusakaniza kwazitsulo zofiira ndi zachikasu, zomwe zimapanga mitundu yosiyanasiyana ya bulauni.
3. Kaphatikizidwe: Iron oxide pigments imatha kupangidwa kudzera m'njira zosiyanasiyana, kuphatikiza mpweya wamankhwala, kuwola kwamafuta, ndikupera kwa mchere wa chitsulo wotchedwa iron oxide. Synthetic chitsulo okusayidi inki amapangidwa pansi zinthu ankalamulira kukwaniritsa ankafuna tinthu kukula, mtundu chiyero, ndi katundu wina.
4. Mapulogalamu:
   • Utoto ndi Zopaka: Iron oxide pigments imagwiritsidwa ntchito kwambiri popanga utoto, zokutira zamafakitale, zomaliza zamagalimoto, ndi zokutira zokongoletsa chifukwa cha kukana kwa nyengo, kukhazikika kwa UV, komanso kusasinthika kwamitundu.
   • Zida Zomangira: Amawonjezeredwa ku konkire, matope, stucco, matailosi, njerwa, ndi miyala yopalira kuti ipangitse utoto, kumapangitsa kukongola, komanso kukhazikika.
   • Pulasitiki ndi Ma polima: Iron oxide inki imaphatikizidwa mu mapulasitiki, mphira, ndi ma polima kuti apange mitundu ndi chitetezo cha UV.
   • Zodzoladzola: Amagwiritsidwa ntchito popanga zodzoladzola ndi zinthu zodzisamalira ngati zopaka milomo, zodzikongoletsera m'maso, zoyambira, ndi zopukuta misomali.
   • Inki ndi Pigment Dispersions: Iron oxide pigment amagwiritsidwa ntchito posindikiza inki, tona, ndi ma dispersions a pigment popanga mapepala, nsalu, ndi zoikamo.
5. Kuganizira Zachilengedwe: Iron oxide pigment imatengedwa kuti ndi yochezeka komanso yotetezeka kuti igwiritsidwe ntchito zosiyanasiyana. Siziika pachiwopsezo chachikulu paumoyo kapena zachilengedwe zikagwiridwa bwino ndikutayidwa.

inki ya iron oxide imagwira ntchito yofunika kwambiri popereka mitundu, chitetezo, ndi kukongola kwazinthu zosiyanasiyana m'mafakitale osiyanasiyana.
