ʻO ka wili wili kū pololei o ka alumini hydroxide

He huahana kemika i hoʻohana nui ʻia ka aluminiuma hydroxide, kūpaʻa kemika maikaʻi, ʻaʻohe ʻawaʻawa, ʻono ʻole, ua lilo ia i mea hoʻopihapiha koʻikoʻi i ka mea uila, nā mea uila, ka hana pepa, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe. Me ka hoʻomaikaʻi nui ʻana o ka aluminiuma hydroxide, ua loli ke ʻano uila o ka ʻili a me ke ʻano kristal, e hopena ana i ka hopena o ka ʻili a me ka hopena o ka nui, no laila he mau waiwai kū hoʻokahi i ka hana kemika, ka hana uila, nā waiwai o ka ʻili a me nā ʻano ʻē aʻe, a he nui nā hana kūikawā. ʻO ka pauka aluminia hydroxide i hana ʻia e ka wili kū pololei aluminia hydroxide ʻaʻole wale ia he mea hana ponoʻī, akā hāʻawi pū i kahi manaʻolana noi ākea no ka hoʻomohala ʻana i nā mea hou, a he hana koʻikoʻi loa ia i nā ʻano like ʻole o ka hoʻokele waiwai aupuni.Guilin HongchengMa ke ʻano he mea hana wili kū pololei o ka alumini hydroxide, i kēia lā no ʻoe e hoʻolauna i ka mākeke noi nui o ka alumini hydroxide.

ʻO ka mākeke noi nui o ka alumini hydroxide:

1. ʻOihana hoʻomaha kuni: he paʻakikī waena ka alumini hydroxide, nā waiwai kino a me nā kemika paʻa i ka mahana o ka lumi, ʻaʻohe ʻawaʻawa, a haʻahaʻa ke kumukūʻai hana. Hoʻomaka ka alumini hydroxide i hoʻomehana ʻia ma kahi o 220C e hoʻomehana i ka decomposition omo, e hoʻokuʻu i ka wai i hui pū ʻia. No ka mea, hoʻopaneʻe kēia kaʻina hana dehydration endothermic i ka puhi ʻana o ka polymer a hoʻolohi i ka wikiwiki o ka puhi ʻana. Hoʻokumu ʻia ia ma ka decomposition o ka nui o ka omo wela, a hoʻokuʻu wale i ka mahu wai i ka decomposition wela, a ʻaʻole e hana i ke kinoea ʻawaʻawa, lapalapa a corrosive paha, ua lilo ka alumini hydroxide i mea hoʻopiha lapalapa inorganic koʻikoʻi.

2. Hoʻopiha a me ka hoʻohui o ka mea hoʻopili a me ka mea hoʻopaʻa: Hiki i ka mea hoʻopihapiha hydroxide alumini ke hoʻomaikaʻi i ka hana hana, ka ikaika, ka conductivity thermal a me ka hana hoʻonui thermal o ka mea hoʻopili a me ka mea hoʻopaʻa, a hiki ke hōʻemi i ka nui o ka mea hoʻopili a hoʻemi i ke kumukūʻai huahana. Ke ulu nei ka hoʻohana ʻana o ka mea hoʻopaʻa ma ʻEulopa a me ʻAmelika Hui Pū ʻIa ma kahi o 5% i ka makahiki, a ke ulu nei ke koi no nā mea hoʻopaʻa ma 1% ma ʻEulopa.

3. Hoʻopili pepa: ʻO ka alumini hydroxide i ka ʻoihana pepa, hoʻohana nui ʻia e like me ka uhi ʻana i ka ʻili, ka hoʻopiha a me ka hana ʻana o ka pepa ʻaʻole hiki ke puhi. I ka makahiki 1940 a me 1950, ua hoʻomaka ka alumini hydroxide e hoʻomohala a hoʻohana ʻia ma ke ʻano he pigment uhi, a ua hoʻokumu i kahi pae hana paʻa, i hoʻohana nui ʻia no ka hana ʻana o ka pepa i uhi ʻia a me ka pepa pahu, pepa kalapona kalapona. Ma Kina, ua emi ka hoʻohana ʻana o ka alumini hydroxide i ka ʻoihana pepa, me ka hoʻomohala ʻana a me ka hana ʻana o ka alumini hydroxide ultrafine, e hoʻomau ka hoʻonui ʻana o ka noi o ka alumini hydroxide i ka ʻoihana pepa. ʻO ka alumini hydroxide, ma ke ʻano he ʻano hou o ka pigment uhi, i hoʻohālikelike ʻia me ka pigment kuʻuna, he nui nā pono: keʻokeʻo kiʻekiʻe, ka nui o ka palaoa maikaʻi, ke ʻano kristal maikaʻi, ka hana hoʻohālikelike maikaʻi me ka mea hoʻokeʻokeʻo, ka omo ʻana o ka ʻīnika maikaʻi. ʻO ka hoʻohana ʻana iā ia ma ke ʻano he pigment, hiki ke hoʻomaikaʻi i ka keʻokeʻo, ka opacity, ka maʻalahi, ka omo ʻana o ka ʻīnika o ka pepa i uhi ʻia, hiki ke hoʻohana ʻia i ka hana ʻana o ka pepa pena, ka pepa kiʻi a me ka pepa puke wehewehe ʻōlelo holomua a me nā pepa holomua ʻē aʻe.

4. Mea hoʻopili niho: ʻaʻohe ʻawaʻawa a ʻono ʻole ka alumini hydroxide, ʻo ka paʻakikī Mohs 2.5-3.5, palupalu a paʻakikī waena, he mea hoʻopili maikaʻi kūlohelohe, hiki ke hana ʻia ka alumini hydroxide ma kahi o nā mea kuʻuna o ka chalk a me ka dicalcium phosphate i loko o ka toothpaste me ka hana maikaʻi. ʻO ka inertia kemika o ka alumini hydroxide e hoʻohālikelike ai me nā mea ʻē aʻe i loko o ka toothpaste; i kēia manawa, hoʻohana nui ʻia i ka toothpaste lāʻau lapaʻau a me nā toothpaste kiʻekiʻe ʻē aʻe.

5. Lāʻau lapaʻau a me nā mea ʻē aʻe: ʻO ka aluminiuma hydroxide kekahi o nā mea nui o ka lāʻau lapaʻau gastric. ʻO ka alumini gel kahi lāʻau lapaʻau kuʻuna no ka hoʻopau ʻana i ka waikawa ʻōpū a me ka mālama ʻana i nā pilikia ʻōpū. Hiki ke hoʻohana ʻia ka alumini chloride i hoʻomākaukau ʻia mai ka alumini hydroxide ma ke ʻano he mea maka ma ke ʻano he condensant i ka lāʻau lapaʻau a me nā mea hoʻonani. Eia kekahi, ua hoʻohana nui ʻia ka alumini hydroxide a me kāna alumini oxide i hoʻomoʻa kūikawā ʻia i nā lāʻau kemika, nā mea hoʻoulu, nā plastics, nā uhi, nā keramika, nā mea refractory, nā mea insulation, nā abrasives a me nā ʻoihana ʻē aʻe.
