He aha ke ʻano o ka Iron Oxide Pigment

ʻO nā puaʻa hao hao he mea synthetic a i ʻole nā ​​mea kūlohelohe i haku ʻia me ka hao a me ka oxygen. Hoʻohana maʻamau ʻia lākou e like me nā kala i nā noi like ʻole ma muli o ko lākou kūpaʻa, lōʻihi, a me nā mea ʻawaʻawa ʻole. Hiki mai nā puaʻa hao hao i nā waihoʻoluʻu like ʻole, me ka ʻulaʻula, melemele, ʻeleʻele, a me ka ʻeleʻele, ma muli o ke ʻano kemika kikoʻī a me nā ʻano hana.

Eia kekahi mau mea nui e pili ana i nā puaʻa hao hao.

1. Hoʻohui ʻia: ʻO nā puaʻa hao oxide ka nui o nā hao hao a me nā oxyhydroxides. ʻO nā pūhui kemika nui ka hao (II) oxide (FeO), hao (III) oxide (Fe2O3), a me ka hao (III) oxyhydroxide (FeO (OH)).
2. Nā ʻano kala kala:
   • ʻO ka hao hao ʻulaʻula (Fe2O3): ʻIke ʻia hoʻi ʻo ka ferric oxide, ʻo ka hao hao ʻulaʻula ka mea hoʻohana maʻamau i ka puaʻa hao ʻokikene. Hāʻawi ia i nā hue mai ka ʻalani-ʻulaʻula a i ka ʻulaʻula hohonu.
   • Yellow Iron Oxide (FeO(OH)): Ua kapa ʻia nō hoʻi ka ʻōkea melemele a i ʻole ka hao iron oxide, hoʻopuka kēia puaʻa i ka melemele a i ka melemele-ʻeleʻele.
   • ʻEleʻele Hao Oxide (FeO a i ʻole Fe3O4): Hoʻohana pinepine ʻia nā puaʻa hao ʻeleʻele no ka pōʻeleʻele a i ʻole ka hoʻoluʻu ʻana.
   • Brown Iron Oxide: ʻO kēia puaʻa ka mea maʻamau i ka hui ʻana o ka ʻulaʻula a me ka melemele hao oxides, e hana ana i nā ʻano kala like ʻole.
3. Synthesis: Hiki ke hana ʻia nā puaʻa hao oxide ma o nā ʻano like ʻole, e like me ka ua kemika, ka hoʻoheheʻe wela, a me ka wili ʻana i nā minerala hao oxide kūlohelohe. Hana ʻia nā puaʻa iron oxide ma lalo o nā kūlana i hoʻopaʻa ʻia e hoʻokō i ka nui o nā mea i makemake ʻia, ka maʻemaʻe kala, a me nā waiwai ʻē aʻe.
4. Nā noi:
   • Nā Pena a me nā Kāpena: Hoʻohana nui ʻia nā puaʻa hao hao i loko o nā pena pena kiʻi kiʻi, nā uhi ʻoihana, nā hoʻopau kaʻa, a me nā mea hoʻonaninani ma muli o ko lākou kū ʻana i ke aniau, paʻa UV, a me ke kala like.
   • Nā Mea Hana Hana: Hoʻohui ʻia lākou i ka sima, ka momi, ka stucco, nā tile, nā pōhaku lepo, a me nā pōhaku paving e hāʻawi i ke kala, hoʻomaikaʻi i ka nani, a hoʻomaikaʻi i ka lōʻihi.
   • Plastics and Polymers: Hoʻohui ʻia nā puaʻa hao hao i loko o nā plastics, rubber, a me nā polymers no ka waihoʻoluʻu a me ka pale UV.
   • Mea Hoʻomaʻamaʻa: Hoʻohana ʻia lākou i nā mea hoʻonaninani a me nā huahana mālama pilikino e like me nā lipsticks, eyeshadows, nā kumu, a me nā nail polishes.
   • ʻO ka ʻīnika a me ka hoʻopuehu ʻana i ka puaʻa: Hoʻohana ʻia nā puaʻa hao hao i ka paʻi ʻana i nā inika, nā toners, a me nā hoʻopuehu puaʻa no ka pepa, textiles, a me nā mea hoʻopili.
5. Noʻonoʻo Kaiapuni: ʻO nā puaʻa hao oxide i manaʻo ʻia he pili kaiapuni a palekana no ka hoʻohana ʻana i nā noi like ʻole. ʻAʻole lākou e hoʻopilikia i ke olakino a i ʻole nā ​​pōʻino kaiapuni ke mālama pono ʻia a hoʻolei ʻia.

He kuleana koʻikoʻi ka iron oxide pigments i ka hāʻawi ʻana i ka waihoʻoluʻu, pale, a me ka hoʻopiʻi nani i nā ʻano huahana ma nā ʻoihana like ʻole.
