Wararka - Lebennada Alumina Sare ee Foornada Qaraxyada

Lebennada alumina-da ee sare loogu talagalay foornooyinka qarxa waxaa laga sameeyaa bauxite heer sare ah oo ah walaxda ugu weyn ee cayriin, kuwaas oo la isku dubo, la cadaadiyo, la qalajiyo oo lagu shido heerkul sare. Waa badeecooyin aan la jari karin oo loo isticmaalo dahaarka foornada qaraxyada.

2. Halkee ayaa lebennada alumina ee sare loo isticmaalaa foornooyinka qarxa?

Lebennada aluminiumka sare leh ayaa laga dhisay usha foornada ee foornada qaraxa. Usha foornada waxay ku taal qaybta sare ee foornada qaraxa. Dhexroorkeedu si tartiib tartiib ah ayuu uga fidaa kor ilaa hoos si uu ula qabsado ballaarinta kulaylka ee kharashka oo uu u yareeyo isku dhaca derbiga foornada ee kharashka. Jidhka foornada ayaa ku jira foornada qaraxa. 50%-60% dhererka waxtarka leh. Deegaankan, dahaarka foornada wuxuu u baahan yahay inuu buuxiyo shuruudahaas, astaamaha lebennada aluminiumka sare lehna waa iska caabin sare, heerkul jilicsan oo sarreeya oo culays saaran, iska caabin aashito, iska caabin alkali ah, iska caabin xooggan oo ka dhan ah nabaad-guurka, iyo iska caabin wanaagsan oo xirasho ah. Waa la qancin karaa, sidaa darteed aad bay ugu habboon tahay in jirka foornada qaraxa lagu dahaadho lebennada aluminiumka sare leh.

Tan kor ku xusan waa hordhac ku saabsan lebennada alumina ee sare ee loogu talagalay foornooyinka qaraxa. Deegaanka dahaarka ee foornada qaraxa waa mid adag waxaana jira noocyo badan oo agab ah oo iska caabiya oo la isticmaalo. Lebennada alumina ee sare ayaa ka mid ah. Waxaa jira 3-5 qeexitaan oo ah lebennada alumina ee sare ee la isticmaalo. Lebennada alumina ee sare ee Robert waxaa loo isticmaali karaa foornooyin kala duwan. Haddii loo baahdo, fadlan nala soo xiriir.
