Lebennada Dahaarka Alumina
Lebennada dahaarka aluminiumkawaxaa laga soo saaraa walxo ceeriin ah oo heer sare ah oo aluminium ah iyada oo loo marayo saamiga adag, cadaadiska sare iyo dab-shid heerkul sare leh. Iyada oo leh heer sare oo Al₂O₃ ah, qaab-dhismeed isku mid ah iyo waxqabad deggan, waxaa si ballaaran loogu isticmaalaa agab dahaadh ah jawiyada warshadaha ee heerkulka sare, duugga badan iyo daxalka.
Lebennadayada dahaarka alumina waxay si fiican u ilaaliyaan foornada warshadaha, foornada, dhuumaha, duufaannada, tuubooyinka iyo qalabka falcelinta, iyagoo si wax ku ool ah u yareynaya xirashada, daxalka iyo kulaylka oo yaraada, waxayna si weyn u hagaajinayaan nolosha adeegga qalabka iyo hufnaanta wax soo saarka.
Waxaan taageernaa cabbirrada gaarka ah, qaababka gaarka ah iyo darajooyinka kala duwan ee alumina si loo daboolo baahiyahaaga gaarka ah ee mashruuca.
Faa'iidooyinka Muhiimka ah:
1. Iska caabinta Heerkulka Sare
Waxay u adkeysan kartaa heerkulka shaqada ee muddada dheer ilaa 1350°C–1750°C, iyadoo ku xiran heerka.
2. Iska caabinta Xidhitaanka Xad-dhaafka ah
Adkaanta sare iyo heerka xoqidda oo hooseeya si wax ku ool ah ayay u adkaystaan xoqidda iyo is jiidjiidka walxaha.
3. Iska caabinta Daxalka oo Xoog leh
Iska caabin wanaagsan oo ka dhan ah aashitada, alkali, slag dhalaalay, boodhka iyo daxalka kiimikada.
4. Xasillooni Kulayl oo Wanaagsan
Heerka fidinta kulaylka oo hooseeya, iska caabin xoog leh oo shoogga kulaylka ah, dildilaac yar.
5. Cimri Dheer oo Adeeg ah
Yaree soo noqnoqoshada dayactirka, hoos u dhig waqtiga shaqada iyo kharashka guud ee hawlgalka.
6. Rakibaadda Fudud
Cabbirrada caadiga ah iyo kuwa gaarka ah ayaa diyaar u ah dhismaha iyo beddelka ku habboon.
