ka hoʻohana ʻana i ka alumini hydroxide

ʻO ka aluminiuma hydroxide, nona ke ʻano he Al(OH)3, hiki ke loaʻa ma ke ʻano ma nā ʻano penei: gibbsite, he mineral ia, a me doyleite, nordstrandite a me bayerite, he mau polymorphs kakaikahi kēia mau mea a pau. Ma muli o kona mau waiwai, hiki iā mākou ke ʻōlelo he mea antacid ka aluminia hydroxide. Loaʻa iā ia nā hoʻohana like ʻole, ʻo ka mea nui ma waena o ia mau mea ka noi lapaʻau.

Nā Waiwai Kemika

Nui nā ʻano like ʻole o ka alumini oxide, me nā ʻano crystalline a me nā ʻano non-crystalline. He mea hoʻokaʻawale uila ia, ʻo ia hoʻi, ʻaʻole ia e alakaʻi i ka uila, a he kiʻekiʻe hoʻi kona conductivity thermal. Eia kekahi, ma kona ʻano crystalline,korundum, ʻo kona paʻakikī e kūpono ai ia ma ke ʻano he mea abrasive. ʻO ke kiʻekiʻe o ka heheʻe ʻana o ka alumini oxide e lilo ia i mea refractory maikaʻi no ka hoʻopili ʻana i nā mīkini wela kiʻekiʻe e like me nā kilns, nā umu, nā incinerators, nā reactors o nā ʻano like ʻole, a me nā ipu hoʻoheheʻe.

Nā waiwai o ka alumini hydroxide

ʻO ka aluminiuma hydroxide i hoʻomaʻemaʻe ʻia he ʻano pauka nui o ke kala keʻokeʻo a i ʻole nā ​​granules me ka density kokoke i 2.42 g i kēlā me kēia mL. ʻAʻole e hoʻoheheʻe ʻia ka aluminiuma hydroxide i lokowai, akā e hoʻoheheʻe wale ʻia i loko o nā kumu a me nā waikawa. Hiki iā ʻoe ke manaʻo e hana ka aluminiuma hydroxide ma ke ʻano he mea amphoteric i loko o ka wai. Inā loaʻa kahi kumu ikaika, e hana ka aluminia hydroxide ma ke ʻano he waikawa. A inā loaʻa kahi waikawa ikaika, e hana ia ma ke ʻano he kumu ikaika.
Pono e mālama pono ʻia ka aluminiuma hydroxide no ka mea hiki i kona hoʻopili ʻia ke hoʻonāukiuki. Eia nō naʻe, e loaʻa wale nā ​​​​ʻeha liʻiliʻi a me nā koena. No ka lapalapa ʻana, ʻaʻole lapalapa ka aluminia hydroxide a ʻaʻole e wela. Eia kekahi, ʻaʻole pane ka aluminia hydroxide, no laila, paʻa ia i nā kūlana ahi a me ka wai.

Nā noi o ka alumini hydroxide

He nui nā noi o ka aluminiuma hydroxide; manaʻo kekahi poʻe he pau ʻole kēia mau hoʻohana. No ka hoʻākāka wale ʻana i ka laulā o nā hoʻohana, hiki iā mākou ke ʻōlelo ua hoʻohana ʻia ka aluminia hydroxide ma ke ʻano he mordant i nā dyes, purifier nowai, mea hoʻohui no nā mea hoʻonani, a hiki i loko o ke ʻano he mea no nā kaʻina hana i ke kiʻi ʻana. Aia kekahi mau noi o ke ʻano liʻiliʻi i nā keramika a me ke kūkulu ʻana. Akā ʻo ke kahua koʻikoʻi kahi e hoʻopili ʻia ai ka alumini hydroxide ʻo ia ka lāʻau lapaʻau.
