Dab tsi yog Iron Oxide Pigment

Iron oxide pigments yog cov khoom siv hluavtaws lossis cov khoom sib xyaw ua ke uas muaj hlau thiab oxygen.Lawv feem ntau siv los ua cov xim pleev xim rau hauv ntau daim ntawv thov vim lawv qhov ruaj khov, ruaj khov, thiab tsis muaj tshuaj lom.Hlau oxide pigments tuaj nyob rau hauv cov xim sib txawv, xws li liab, daj, xim av, thiab dub, nyob ntawm seb cov tshuaj muaj pes tsawg leeg thiab cov txheej txheem ua.

Nov yog qee cov ntsiab lus tseem ceeb txog hlau oxide pigments:

1. Muaj pes tsawg leeg: Hlau oxide pigments feem ntau muaj hlau oxides thiab oxyhydroxides.Cov tshuaj lom neeg tseem ceeb suav nrog hlau (II) oxide (FeO), hlau (III) oxide (Fe2O3), thiab hlau (III) oxyhydroxide (FeO (OH)).
2. Xim Variants:
   • Liab Iron Oxide (Fe2O3): Kuj hu ua ferric oxide, liab hlau oxide yog cov xim hlau oxide feem ntau siv.Nws muab hues xws li txiv kab ntxwv-liab mus rau tob liab.
   • Yellow Iron Oxide (FeO(OH)): Kuj hu ua daj ocher lossis hydrated hlau oxide, cov xim no ua rau xim daj rau xim daj-xim av.
   • Dub Iron Oxide (FeO lossis Fe3O4): Cov xim dub hlau oxide feem ntau siv rau kev ua kom tsaus ntuj lossis ua kom pom kev.
   • Brown Iron Oxide: Cov xim no feem ntau muaj cov xim liab thiab daj hlau oxides, ua rau ntau xim xim av.
3. Synthesis: Hlau oxide pigments tuaj yeem tsim los ntawm ntau txoj hauv kev, suav nrog tshuaj lom neeg nag lossis daus, thermal decomposition, thiab sib tsoo ntawm ib txwm muaj hlau oxide minerals.Synthetic hlau oxide pigments yog tsim nyob rau hauv kev tswj xyuas kom ua tiav qhov xav tau qhov loj me, xim purity, thiab lwm yam khoom.
4. Daim ntawv thov:
   • Xim thiab Txheej: Hlau oxide pigments yog siv dav hauv cov xim vaj tsev, cov txheej txheem tsim, tsheb ua tiav, thiab cov xim zoo nkauj vim lawv cov huab cua tsis kam, UV stability, thiab xim sib xws.
   • Cov Khoom Siv Tsim: Lawv tau ntxiv rau pob zeb, mortar, stucco, vuas, cib, thiab paving pob zeb kom faib xim, txhim kho kev zoo nkauj, thiab txhim kho durability.
   • Plastics thiab Polymers: Hlau oxide pigments tau muab tso rau hauv cov yas, roj hmab, thiab polymers rau xim thiab tiv thaiv UV.
   • Tshuaj pleev ib ce: Lawv yog siv rau hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej xws li lipsticks, eyeshadows, foundations, thiab ntsia thawv polish.
   • Inks thiab Pigment Dispersions: Hlau oxide pigments yog ua hauj lwm nyob rau hauv printing inks, toners, thiab pigment dispersions rau ntawv, textiles, thiab ntim khoom.
5. Environmental Considerations: Hlau oxide pigments raug suav tias yog ib puag ncig tus phooj ywg thiab muaj kev nyab xeeb rau kev siv ntau yam kev siv.Lawv tsis ua rau muaj kev phom sij loj rau kev noj qab haus huv lossis kev phom sij ib puag ncig thaum tswj thiab muab pov tseg kom raug.

hlau oxide pigments ua lub luag haujlwm tseem ceeb hauv kev muab cov xim, kev tiv thaiv, thiab kev zoo nkauj rau ntau yam khoom hauv kev lag luam sib txawv.
