Alumina ndi zinthu wamba zopanda zitsulo, zomwe zimagwiritsidwa ntchito kwambiri m'makampani, zomangamanga, zamagetsi, zamankhwala ndi zina.

Chiyambi cha Alumina

Alumina ndi ufa woyera kapena wonyezimira wokhala ndi mamolekyu a Al2O3 ndi kulemera kwa 101.96.Ndi gulu lopangidwa ndi aluminiyumu ndi okosijeni, lomwe limakhala ndi malo osungunuka kwambiri komanso olimba.Alumina ndizofunikira kwambiri zopangira mafakitale, zomwe zimagwiritsidwa ntchito kwambiri muzoumba, magalasi, zamagetsi, zamankhwala ndi zina.

Thupi katundu aluminiyamu

The thupi katundu aluminiyamu makamaka monga kachulukidwe, kuuma, matenthedwe bata, kuwala katundu ndi zina zotero.Kuchulukana kwa alumina ndi 3.9-4.0g/cm3, kuuma kwake ndi Mohs hardness 9, kukhazikika kwamafuta ndikokwera, ndipo malo osungunuka ndi 2054 ℃.Kuphatikiza apo, aluminiyamu imakhalanso ndi zinthu zabwino zowoneka bwino komanso ndizofunikira kwambiri zowunikira.

Chemical katundu wa aluminiyamu

The mankhwala katundu wa aluminiyamu makamaka monga mmene anachita ndi zinthu zosiyanasiyana mankhwala, asidi ndi alkali.Alumina amakumana ndi asidi kupanga aluminiyamu mchere ndi madzi, ndi alkali kupanga aluminiyamu hydroxide ndi madzi.Nthawi yomweyo, aluminiyamu imakhalanso ndi ma acidic oxides, omwe amatha kuchitapo kanthu ndi mankhwala ambiri.

Kukonzekera njira ya aluminiyamu

Njira zazikulu zokonzekera alumina ndi njira yamankhwala, njira yakuthupi ndi zina zotero.The mankhwala njira makamaka kudzera neutralization anachita a aluminiyamu mchere ndi hydroxide kupeza zotayidwa hydroxide, ndiyeno kudzera kutentha kutentha kuwotcha kuti aluminum okusayidi.Njira yakuthupi imakhala makamaka kudzera pakuwola kwa ore, distillation, crystallization ndi njira zina zopezera alumina.

Alumina ntchito gawo

Alumina amagwiritsidwa ntchito kwambiri m'makampani, zomangamanga, zamagetsi, zamankhwala ndi zina.M'munda wamafakitale, aluminiyamu imagwiritsidwa ntchito popanga zoumba, magalasi, zokutira ndi zina zotero.Mu gawo la zomangamanga, alumina amagwiritsidwa ntchito popanga zitseko, Windows, makoma a nsalu ndi zina zotero.M'munda wamagetsi, alumina amagwiritsidwa ntchito popanga matabwa ozungulira, zipangizo zamagetsi, ndi zina zotero. M'munda wa mankhwala, alumina amagwiritsidwa ntchito popanga mankhwala, zipangizo zamankhwala ndi zina zotero.

Chiyembekezo cha chitukuko cha aluminiyamu

Ndi chitukuko chosalekeza cha sayansi ndi ukadaulo, gawo logwiritsira ntchito alumina likuchulukirachulukira.M'tsogolomu, ndi chitukuko chofulumira cha zipangizo zatsopano, mphamvu zatsopano ndi madera ena, kufunikira kwa alumina kudzapitirira kuwonjezeka.Panthawi imodzimodziyo, ndikusintha kosalekeza kwa zofunikira zoteteza chilengedwe, teknoloji yopanga alumina idzapitirizabe kusintha, ndipo njira zopangira zachilengedwe, zogwira mtima komanso zopulumutsa mphamvu zidzakhala chitukuko.

Alumina ndi chinthu chofunikira chopanda zitsulo, chomwe chili ndi ntchito zambiri komanso kufunikira kwachuma.M'tsogolomu, ndi chitukuko chofulumira cha zipangizo zatsopano ndi mphamvu zatsopano ndi madera ena, kufunikira kwa aluminiyamu kudzapitirira kuwonjezeka, pamene teknoloji yopanga aluminiyamu idzapitirizabe kupititsa patsogolo, ndikuthandizira kwambiri pa chitukuko cha anthu.
