Lebennada xumbo ee Alumina
Leben kubbad godan oo Alumina ah/leben xumbo Alumina ahwaa leben khafiif ah oo khafiif ah oo ka samaysan alumina oo nadiif ah oo isku-dhafan, oo lagu daray budada alumina ee aadka u fiican iyo qalab gaar ah. Ka dib marka la sameeyo, la qalajiyo oo la shido heerkul aad u sarreeya oo ah 1750℃, lebenku wuxuu leeyahay qaab-dhismeed malab ah oo daloolsan. Waxay isku daraysaa iska caabin heer sare ah oo heer sare ah iyo gudbin kuleyl aad u hooseeya, taasoo ka dhigaysa agab dahaadh ah oo ku habboon foornooyinka warshadaha ee heerkulka aadka u sarreeya.
Habaynta iyo Adeegga
1. Leben caadi ah oo la habeeyey, leben qaloocan iyo leben qaab gaar ah leh iyadoo loo eegayo sawirrada
2. Badeecooyin leh nadiifin kala duwan: 90%, 95%, 98% ayaa la heli karaa
3. Dhoofinta baakadaha caadiga ah, oo ku habboon gaadiidka badda iyo hawada
4. Bixi warbixinnada kormeerka tayada leh, shahaadooyinka asalka ah iyo dukumentiyada kale ee ganacsiga shisheeye
Faa'iidooyinka Muhiimka ah:
1. Iska caabinta Heerkulka Aad u Sareeya
Heerkulka adeegga muddada-dheer: 1700–1750℃, ugu badnaan ilaa 1800℃. Isbeddel toos ah oo yar oo joogto ah marka dib loo kululeeyo iyo cabbir deggan heerkulka sare.
2. Dahaarka Kulaylka ee aadka u Fiican & Kaydinta Tamarta
Koronto-qaadis aad u hooseeya oo leh saameyn tamar-badbaadin oo cajiib ah. Heerka keydinta tamarta wuxuu gaari karaa in ka badan 30%, taasoo si weyn u yareyneysa kharashka shidaalka.
3. Fudud & Xoog Sare
Cufnaanta hoose ee mugga ayaa yaraynaysa culayska foornada. Iyada oo leh xoog burburin qabow oo wanaagsan, waxaa si toos ah loogu isticmaali karaa lakab shaqo oo heerkul sare leh.
4. Shoogga Kulaylka iyo Daxalka oo Wanaagsan
Waxay u adkaysataa daxalka aashitada iyo alkali, nabaad-guurka, iyo iska caabbinta shoogga kulaylka oo aad u fiican, oo ku habboon xaaladaha kululaynta iyo qaboojinta ee soo noqnoqda.

Su'aalaha Badiya La Weydiiyo
Ma u baahan tahay caawimo? Hubi inaad booqato golayaashayada taageerada si aad u hesho jawaabaha su'aalahaaga!
Waxaan nahay soo-saare dhab ah, warshadeenu waxay ku takhasustay soo saarista agabyada aan la qabsan karin in ka badan 30 sano. Waxaan ballan qaadaynaa inaan bixinno qiimaha ugu fiican, adeegga ugu fiican ee iibka kahor iyo adeegga iibka kadib.
Nidaam kasta oo wax soo saar ah, RBT waxay leedahay nidaam QC oo dhammaystiran oo loogu talagalay halabuurka kiimikada iyo sifooyinka jireed. Waxaanan tijaabin doonnaa alaabta, shahaadada tayadana waxaa lala soo raaci doonaa alaabta. Haddii aad leedahay shuruudo gaar ah, waxaan isku dayi doonnaa sida ugu wanaagsan ee aan u dabooli karno.
Iyadoo ku xiran tirada, waqtiga keenisteenu wuu ka duwan yahay. Laakiin waxaan ballan qaadaynaa inaan sida ugu dhakhsaha badan u soo dirno iyadoo tayo la hubo la hubo.
Dabcan, waxaan bixinaa muunado bilaash ah.
Haa, dabcan, waa lagu soo dhaweynayaa inaad booqato shirkadda RBT iyo alaabtayada.
Ma jiro xad, waxaan ku siin karnaa talada iyo xalka ugu fiican iyadoo loo eegayo xaaladdaada.
Waxaan samaynaynay agab aan la qabsan karin in ka badan 30 sano, waxaan leenahay taageero farsamo oo xooggan iyo waayo-aragnimo qani ah, waxaan ka caawin karnaa macaamiisha inay naqshadeeyaan foosto kala duwan oo ay bixiyaan adeeg hal joogsi ah.
