ʻO ka alumina he mea maʻamau non-metallic maʻamau, hoʻohana nui ʻia i ka ʻoihana, kūkulu hale, uila, lāʻau lapaʻau a me nā ʻoihana ʻē aʻe.

Alumina Introduction

ʻO ka alumina he pauka keʻokeʻo keʻokeʻo a keʻokeʻo paha me kahi ʻano molekala o Al2O3 a me ke kaumaha molekala o 101.96.He hui ia i haku ʻia me ka alumini a me ka oxygen, nona ka helu heheʻe kiʻekiʻe a me ka paʻakikī.ʻO ka alumina kahi mea waiwai nui o ka ʻoihana, i hoʻohana nui ʻia i nā ceramics, aniani, uila, lāʻau lapaʻau a me nā ʻano ʻē aʻe.

Nā waiwai kino o ka alumina

ʻO nā waiwai kino o ka alumina ka nui o ka density, ka paʻakikī, ka paʻa wela, nā waiwai optical a pēlā aku.ʻO ka nui o ka alumina he 3.9-4.0g / cm3, ʻo ka paʻakikī ʻo Mohs paʻakikī 9, kiʻekiʻe ka paʻa wela, a ʻo ka helu hoʻoheheʻe he 2054 ℃.Eia kekahi, loaʻa i ka alumina nā waiwai optical maikaʻi a he mea optical mea nui.

Nā waiwai kemika o ka alumina

ʻO nā waiwai kemika o ka alumina ka mea nui i ka hana pane me nā mea kemika like ʻole, ka waikawa a me ka alkali.Hoʻopili ka alumina me ka waikawa e hana i ka paʻakai aluminika a me ka wai, a me ka alkali e hana i ka alumini hydroxide a me ka wai.I ka manawa like, loaʻa i ka alumina nā waiwai o nā oxide acidic, hiki ke hana me nā kinikini he nui.

ʻO ke ʻano hoʻomākaukau o ka alumina

ʻO nā ʻano hoʻomākaukau nui o ka alumina he ʻano kemika, ʻano kino a pēlā aku.ʻO ke ʻano hana kemika ma o ka hopena neutralization o ka paʻakai alumini a me ka hydroxide e kiʻi i ka alumini hydroxide, a laila ma ke ahi wela kiʻekiʻe e kiʻi i ka alumini oxide.ʻO ke ʻano kino ka mea nui ma o ka decomposition oka, distillation, crystallization a me nā hana ʻē aʻe e loaʻa ai ka alumina.

kahua noi alumina

Hoʻohana nui ʻia ka alumina i ka ʻoihana, kūkulu, uila, lāʻau lapaʻau a me nā ʻoihana ʻē aʻe.Ma kaʻoihanaʻoihana, hoʻohanaʻia ka alumina i ka hanaʻana i nā seramika, ke aniani, nā uhi a me nā mea'ē aʻe.Ma ka ʻoihana kūkulu, hoʻohana ʻia ka alumina e hana i nā puka, Windows, nā pā pale a pēlā aku.Ma ke kahua uila, hoʻohana ʻia ka alumina e hana i nā papa kaapuni, nā mea uila, a me nā mea ʻē aʻe.

ʻO ka manaʻolana hoʻomohala o ka alumina

Me ka hoʻomau mau ʻana o ka ʻepekema a me ka ʻenehana, ʻoi aku ka nui o ke kahua noi o ka alumina.I ka wā e hiki mai ana, me ka hoʻomohala wikiwiki ʻana o nā mea hou, ka ikehu hou a me nā māla ʻē aʻe, e hoʻomau ka piʻi ʻana o ka alumina.I ka manawa like, me ka hoʻomau mau ʻana o nā koi palekana kaiapuni, e hoʻomau ka hoʻomaikaʻi ʻana o ka ʻenehana hana o ka alumina, a ʻoi aku ka maikaʻi o ke kaiapuni, maikaʻi a me ka mālama ʻana i ka ikehu e lilo i ke ʻano hoʻomohala.

ʻO ka alumina he mea koʻikoʻi koʻikoʻi non-metallic, nona ka nui o ka hoʻohana a me ka waiwai waiwai nui.I ka wā e hiki mai ana, me ka ulu wikiwiki ʻana o nā mea hou a me ka ikehu hou a me nā māla ʻē aʻe, e hoʻomau ka hoʻonui ʻana i ka makemake no ka alumina, ʻoiai e hoʻomau ka hoʻomaikaʻi ʻana o ka ʻenehana hana o ka alumina, a hāʻawi i nā kōkua nui i ka ulu ʻana o ke kanaka.
