Astaamaha
Leben alumina xumbo waxay leeyihiin sifooyin kala duwan:
1. ** Xakamaynta Kulul Sare**:Dhaqdhaqaaqooda kulaylka hooseeya waxay ka dhigtaa insulators aad u fiican, yaraynta kulaylka luminta jawiga heerkulka sare.
2. **Nadiifin Sare**:Laga sameeyay aluminium saafi ah oo sarreeya, lebenkan waxay bixiyaan waxqabad heersare ah xaalado aad u daran.
3. ** Fudud:Isku darka xumbo alumina waxay yaraynaysaa cufnaanta guud, taasoo ka dhigaysa leben fudud oo fudud in la xakameeyo lana rakibo.
4. ** Caabbinta Heerkulka Sare**:Waxay u adkeysan karaan heerkul aad u sarreeya, oo badanaa ka sarreeya 1800 ° C, taas oo ka dhigaysa iyaga oo ku habboon in loo isticmaalo foornada heerkulka sare leh iyo foornada.
5. ** Iska caabinta Daxalka**:Waxay leeyihiin iska caabin wanaagsan oo ay iskaga caabiyaan weerarka kiimikaad, gaar ahaan kuwa ka soo baxa biraha iyo biraha dhalaalay.
6. ** Balaadhinta kulaylka Hoose ***:Habkani wuxuu caawiyaa ilaalinta sharafta qaabdhismeedka wuxuuna yareeyaa khatarta dillaaca baaskiilka kulaylka.
7. **Awoodda Makaanikada**:Inkasta oo ay khafiif yihiin, waxay bixiyaan awood farsamo oo wanaagsan iyo adkeysiga xaaladaha hawlgalka.
Tilmaamahani waxay ka dhigaan leben aluminium xumbo ah oo si gaar ah faa'iido ugu leh warshadaha sida biraha, dhoobada, iyo wax soo saarka dhalooyinka.
Codsiga caadiga ah
Si ballaaran loo isticmaalo warshadaha sida biraha, refractories, ceramics, petrochemical, galaas, koronto, iwm. Waxa loo isticmaali karaa sida dahaarka kulul wejiga refractory ee pyrolizer, foornada kulul ee qarxinta, foornada dib u kululaynta, foornada tunnel-ka, foornada dhoobada la riixo, foornada crucible , foornada korontada, iwm.
