Sharaxaadda Lebenka Xumbo Alumina
Lebenka dabka ee xumbo-dabka Alumina waa nooc cusub oo ah walxo kuleyl heer sare ah oo lagu dahaadho kuleyliyaha waxaana laga sameeyay alumina warshadeed oo ku jirta foornada korontada iyada oo loo marayo dhalaalid iyo afuufid. Qaab crystal ah oo ah leben bir ah oo aan lahayn alumina waa a-Al2O3 microcrystal, jirka ugu weynna waa xumbo alumina ah oo laga samayn karo dhammaan noocyada alaabada leh qaabab kala duwan si loogu adeego heerkulka ugu sarreeya ee 1800℃ oo leh xoog farsamo oo sarreeya iyo cufnaan yar.
Sifooyinka leben xumbo Alumina ah
- Miisaan fudud,
- Tamarta oo la keydiyo,
- Kharashka dhismaha oo hooseeya,
- Iska caabin heerkulka sare,
- Isbeddel toosan oo dib-u-kululayn hooseeya,
- Iska caabin fiican oo kulka ah.
Habka Wax Soo Saarka ee leben xumbo Alumina
Bubble Firebrick-ka aluminiumku wuxuu qaataa kubbadda xumbo alumina sida agabka ugu muhiimsan ee ceeriin, budada ultrafine ee waxqabadka sare leh sida wakiilka isku-darka iyo walaxda dabiiciga ah sida wakiilka isku xidhka iyada oo loo marayo qaabaynta iyo qalajinta, ka dibna waxaa lagu ridayaa foornada heerkulka sare.
Faa'iidada leben xumbo Alumina ah
Lebenka dabka ee aluminiumka ah wuxuu leeyahay astaamo ah dahaarka kulaylka iyo kontoroolka kulaylka oo hooseeya, taas oo keeni karta saameyn weyn oo dahaarka kulaylka ah, yarayn karta qashinka kulaylka iyo wanaajinta hufnaanta kulaylka. Isticmaalka lebenka aluminiinka ee aluminiumka ah wuxuu badbaadin karaa tamar ilaa 30%. Heerkulka adeegga ee block-ka alumina waa mid sarreeya ilaa 1750 ℃. Xasilloonida kuleylku waa wanaagsan tahay heerka isbeddelka toosan ee dib-u-kulaylinta waa mid hooseeya, block-ka xumbo ee aluminiumka ah wuxuu keeni karaa cimri dheer oo adeeg ah.
