Chii chinonzi Iron Oxide Pigment

Iron oxide pigments inogadzirwa kana kuti inowanzoitika inoumbwa nesimbi uye oksijeni. Iwo anowanzo shandiswa semavara mumashandisirwo akasiyana siyana nekuda kwekugadzikana kwawo, kusimba, uye kusiri-chepfu. Iron oxide pigments inouya mumarudzi akasiyana-siyana, kusanganisira tsvuku, yero, tsvuku, uye yakasviba, zvichienderana nemakemikari chaiwo uye nzira dzekugadzirisa.

Heano mamwe mapoinzi akakosha nezve iron oxide pigments:

1. Kuumbwa: Iron oxide pigments inonyanya kusanganisira iron oxides uye oxyhydroxides. Mishonga huru yemakemikari inosanganisira iron(II) oxide (FeO), iron(III) oxide (Fe2O3), uye iron(III) oxyhydroxide (FeO(OH)).
2. Color Variants:
   • Red Iron Oxide (Fe2O3): Iyo inozivikanwawo se ferric oxide, red iron oxide ndiyo inonyanya kushandiswa iron oxide pigment. Inopa hues kubva kuorenji-tsvuku kusvika kune yakatsvuka yakadzika.
   • Yellow Iron Oxide (FeO(OH)): Iyo inonziwo yellow ocher kana hydrated iron oxide, iyi pigment inoburitsa yero kune yero-brown shades.
   • Black Iron Oxide (FeO kana Fe3O4): Black iron oxide pigments inowanzoshandiswa kusviba kana kuita shading zvinangwa.
   • Brown Iron Oxide: Iyi pigment inowanzo sanganisira musanganiswa weiyo tsvuku uye yero iron oxides, ichigadzira akasiyana shades ebrown.
3. Synthesis: Iron oxide pigments inogona kugadzirwa nenzira dzakasiyana siyana, kusanganisira kunaya kwemakemikari, kuora kwekupisa, uye kukuya kwechisikigo chesimbi oxide minerals. Synthetic iron oxide pigments inogadzirwa pasi pemamiriro ekudzora kuti iwane yaidiwa particle size, kuchena kwemavara, uye zvimwe zvivakwa.
4. Applications:
   • Paints uye Coatings: Iron oxide pigments inoshandiswa zvakanyanya mukugadzira pendi, maindasitiri ejasi, mota inopera, uye yekushongedza machira nekuda kwekushomeka kwemamiriro ekunze, kugadzikana kweUV, uye kusimba kwemavara.
   • Zvishandiso Zvekuvaka: Zvinowedzerwa kune kongiri, dhaka, stucco, mataira, zvidhinha, uye matombo ekumisikidza kuti ape ruvara, anonatsiridza kukwezva, uye kunatsiridza kusimba.
   • Mapurasitiki nemaPolima: Iron oxide pigments inosanganiswa mumapurasitiki, rabha, uye mapolymers emavara uye kuchengetedzwa kweUV.
   • Cosmetics: Zvinoshandiswa muzvizora uye zvigadzirwa zvekuchengeta munhu senge lipsticks, eyeshadows, magadziko, uye zvipikiri zvekupolisha.
   • Ingi uye Pigment Dispersions: Iron oxide pigments inoshandiswa mukudhinda ingi, toner, uye pigment dispersions pamapepa, machira, uye zvekurongedza zvinhu.
5. Mafungiro Ezvakatipoteredza: Iron oxide pigments inoonekwa seyakanaka nharaunda uye yakachengeteka kushandiswa mukushandisa kwakasiyana. Izvo hazvikonzere njodzi dzehutano dzakakosha kana njodzi dzezvakatipoteredza kana dzakabatwa nemazvo uye dzakaraswa.

iron oxide pigments inoita basa rakakosha mukupa ruvara, dziviriro, uye kunaka kukwezva kune akawanda ezvigadzirwa mumaindasitiri akasiyana.
