Sharaxaada bulukeetiga xumbo alumina
Lebenka dab-damiska ee alumina waa nooc cusub oo heerkul sare ah agabka dahaarka kuleyliyaha waxaana laga sameeyay alumina warshadeed foornada korontada iyadoo loo marayo dhalaalid iyo afuufid. alumina xumbo refractory leben crystal form waa a-Al2O3 microcrystal iyo jirka ugu weyn waa alumina xumbo kaas oo laga samayn karaa si ay u noqdaan dhammaan noocyada kala duwan ee alaabta leh qaabab kala duwan u adeegaya heerkulka ugu sarreeya ee 1800 ℃ oo leh xoog farsamo sare iyo cufnaanta bulk hoose.
Astaamaha bulukeetiga xumbo ee alumina
- Miisaan fudud,
- Kaydinta tamarta,
- Qiimaha dhismaha oo hooseeya,
- Iska caabin heerkul sare ah,
- Isbeddel toosan oo dib u kululeynaya,
- Iska caabbinta shoogga kulaylka wanaagsan.
Habka wax-soo-saarka ee lebenka xumbo ee aluminium
Aluminium bubblle firebrick waxay qaataan kubbadda xumbo alumina sida alaabta ceeriin ee ugu muhiimsan, budada ultrafine ee waxqabadka sare leh sida wakiilka ku lifaaqan iyo walaxda organic sida wakiilka xira iyada oo loo marayo qaabaynta iyo qalajinta, ka dibna waxaa lagu shidaa foornada heerkulka sare.
Faa'iidada Lebenka Xumbo Alumina
Aluminium bubblle lebenka dabka ayaa leh sifooyinka kuleylka kulaylka iyo kuleylka hooseeya, taas oo keeni karta saameynta kuleylka weyn ee kuleylka, yareynta qashinka kulaylka iyo hagaajinta waxtarka kulaylka. Isticmaalka lebenka aluminium bubblle refractory waxay badbaadin kartaa tamarta sare ilaa 30%. iyo alumina bubble block' heerkulka adeeggu waa mid sarreeya ilaa 1750 ℃. xasiloonida kulaylku waa wanaagsan tahay iyo dib u kululaynta heerka isbeddelka tooska ah waa mid hooseeya, xannibaadda xumbo aluminium waxay keeni kartaa nolosha adeegga dheer.

Codsiga bulukeeti xumbo aluminium ah
Lebenka xumbada alumina waa nooc ka mid ah walxaha dib-u-celinta muhiimka u ah iska caabinta heerkulka sare iyo shuruudaha gaarka ah ee jagooyinka foornada iyo foornada, taas oo inta badan loo isticmaalo sida leben dahaarka lakabka dahaarka ee foornada iyo foornada, iyo sidoo kale leben aluminium ah ayaa loo isticmaali karaa adeegga dahaarka ku jira soo saarida quartz daahirnimo sare ee warshadaha elektiroonigga ah sida dahaarka dhoobada dhoobada marawaxadaha gaaska iyo dahaarka kayd ee reactors.
Alumina Xumbo-Beenka Soosaaraha ee Warshada Refractory ee RS
Warshada refractory ee RS sida xirfadle alumina ah oo soo saaraha lebenka xumbo ee Shiinaha, waxay leeyihiin faa'iidooyin badan oo tartan ah suuqa. Haddii aad hayso baahi leben aluminium xumbo ah, ama aad hayso su'aalo ku saabsan tusmooyinka jirka iyo kiimikada, fadlan nala soo xiriir si bilaash ah, waxaanu ku siin doonaa leben caag ah oo tayo sare leh.
