Kedu ihe bụ Iron oxide pigmenti

Iron oxide pigmenti bụ ihe sịntetik ma ọ bụ ihe sitere n'okike nke mejupụtara ígwè na oxygen. A na-ejikarị ha eme ihe dị ka ndị na-agba agba na ngwa dị iche iche n'ihi nkwụsi ike ha, ịdịte aka, na adịghị egbu egbu. Ígwè oxide pigmenti na-abịa na agba dị iche iche, gụnyere ọbara ọbara, odo, aja aja, na oji, dabere n'ụdị kemịkalụ akọwapụtara na usoro nhazi.

Nke a bụ isi ihe ụfọdụ gbasara pigmenti iron oxide:

  1. Ihe mejupụtara: Ígwè oxide pigment bụ isi bụ iron oxides na oxyhydroxides. Ihe mejupụtara kemịkalụ bụ isi gụnyere iron (II) oxide (FeO), iron (III) oxide (Fe2O3), na iron (III) oxyhydroxide (FeO (OH)).
  2. Ụdị agba:
    • Red Iron Oxide (Fe2O3): A makwaara dị ka ferric oxide, iron oxide na-acha uhie uhie bụ pigmenti ígwè oxide a na-ejikarị eme ihe. Ọ na-enye agba sitere na oroma-acha ọbara ọbara ruo na-acha uhie uhie miri emi.
    • Yellow Iron Oxide (FeO (OH)): A na-akpọkwa ocher odo ma ọ bụ hydrated iron oxide, pigmenti a na-amịpụta odo ruo odo-agba aja aja.
    • Black Iron Oxide (FeO ma ọ bụ Fe3O4): A na-ejikarị pigmenti ojii eme ihe maka ịgba ọchịchịrị ma ọ bụ ndo.
    • Brown Iron Oxide: Nri a na-enwekarị ngwakọta nke ígwè oxides uhie na odo odo, na-emepụta ndò dị iche iche nke aja aja.
  3. Synthesis: Enwere ike imepụta pigmenti iron oxide site na ụzọ dị iche iche, gụnyere mmiri ozuzo kemịkalụ, ire ere ọkụ, na igwe mineral iron oxide sitere n'okike. A na-emepụta pigmenti ígwè oxide sịntetịt n'okpuru ọnọdụ a na-achịkwa iji nweta nha nha nha, ịdị ọcha agba, na ihe ndị ọzọ.
  4. Ngwa:
    • Agba na mkpuchi: A na-eji pigmenti ígwè oxide eme ihe n'ọtụtụ ihe na eserese ụlọ, ihe mkpuchi ụlọ ọrụ, imecha ụgbọ ala, na mkpuchi ihe ịchọ mma n'ihi nguzogide ihu igwe ha, nkwụsi ike UV, na agba agba.
    • Ihe eji arụ ọrụ: A na-agbakwunye ha na kọnkịtị, ngwa agha, stucco, taịl, brik na nkume a na-akpụ akpụ iji nye agba agba, kwalite ọmarịcha mma, ma kwalite ịdịte aka.
    • Plastics na Polymers: A na-etinye pigmenti ígwè oxide n'ime plastik, rọba, na polymers maka agba na nchedo UV.
    • Ihe ịchọ mma: A na-eji ha eme ihe ịchọ mma na ngwaahịa nlekọta onwe onye dị ka lipstick, nkpuchi anya, ntọala, na ntu ntu.
    • Ink na Mgbasa Pigment: A na-eji pigmenti ígwè oxide arụ ọrụ na ink ibipụta, toner, na pigmenti mgbasa maka akwụkwọ, textiles, na ihe nkwakọ ngwaahịa.
  5. Ihe gbasara gburugburu ebe obibi: A na-ahụta pigmenti iron oxide dị ka enyi na gburugburu ebe obibi yana nchekwa maka ojiji na ngwa dị iche iche. Ha anaghị ebute nnukwu ihe egwu ahụike ma ọ bụ ihe egwu gburugburu ebe obibi mgbe ejiri ya nke ọma ma tụfuo ya.

Iron oxide pigment na-arụ ọrụ dị oke mkpa n'inye agba, nchebe na ịma mma maka ngwaahịa dị iche iche n'ofe ụlọ ọrụ dị iche iche.
