Warshadda lebenka ee aluminiumka ah ee miisaanka fudud iyo kuwa wax soo saarka | Rongsheng

Sharaxaad Gaaban:

Lebenka dahaarka sare ee alumina waa nooc ka mid ah kuwa aan laydhka lahayn, qaybta ugu weyn ee uu ka kooban yahay waa Al2O3. Haddii maaddada Al2O3 ay ka sarreyso 90%, waxaa loo yaqaan lebenka corundum. Iyada oo ay ugu wacan tahay kheyraad kala duwan, heerarka dalalka kala duwan ma aha kuwo gebi ahaanba isku mid ah. Tusaale ahaan, waddamada Yurub, xadka hoose ee maaddada Al2O3 ee loogu talagalay kuwa alumina-da ee sare waa 42%. Shiinaha, maaddada Al2O3 ee lebenka alumina ee sare waxaa guud ahaan loo qaybiyaa saddex darajo: Heerka I - Heerka Al2O3 > 75%; heerka II - Heerka Al2O3 waa 60-75%; heerka III - Heerka Al2O3 waa 48-60%.

Codsiga:

Lebennada dahaarka sare leh ee alumina ayaa si weyn loogu isticmaalaa dhismaha dahaarka gudaha ee foornada warshadaha, sida foornada qaraxa, foornada kulul ee qaraxda, dusha sare ee foornada korontada ku shaqeysa, reverberator, foornada sibidhka wareega iyo wixii la mid ah. Intaa waxaa dheer, lebennada alumina ee sare leh ayaa sidoo kale si weyn loogu isticmaalaa lebennada hubinta dib-u-cusboonaysiinta, joojinta nidaamka tuurista joogtada ah, lebenka afka, iwm.
