Shaybaar Alumina ah oo tayo sare leh oo leh Shaybaar Alumina ah oo cad oo leh Muunad Bilaash ah
Alumina cad oo la isku daray / Corundum cadBurburwaa walax heer sare ah oo iska caabbin karta, oo laga sameeyay budada alumina tayo sare leh iyadoo dhalaalaysa heerkul ka sarreeya 2000 ℃ foornada korantada iyo qaboojinta, oo loo kala saaray cabbirro kala duwan oo hadhuudh ah. Alumina-da cad ee isku dhafan ayaa ah walaxda ugu weyn ee ceeriin ah ee loogu talagalay soo saarista agabyada aan qaabaysnayn iyo kuwa qaabaysan.
Alumina cad oo la isku daray waxaa laga sameeyaa budada alumina ee saafiga ah oo sodium yar leh iyadoo lagu dhalaalayo heerkulka sare, lagu qaboojinayo kiristaalka, ka dibna la burburinayo. Birta cad ee alumina ee la isku daray ayaa si adag loo xakameeyay si loo ilaaliyo qaybinta cabbirka hadhuudhka iyo muuqaalka joogtada ah.
Waxaa si caadi ah loogu isticmaalaa qalabka lagu sameeyo laambadaha, qalabka birta lagu ordo, qalabka isku darka qoryaha ee aan laydhka lahayn iyo alaabada kale ee monolithic refractory; Qalabka loo isticmaalo qaabaysan ee aan laydhka lahayn, waxaa inta badan loo isticmaalaa alaabta ceeriin ee tayada sare leh ee lebenka corundum, corundum mullite, leben bir ah oo daloolo leh oo sifeynaya, qoriga buufinta ee isku dhafan, sameynta birta iyo warshadaha shubista joogtada ah.
Waxa kale oo loo isticmaali karaa agab ahaan rinjiyeynta, shubidda saxda ah, buufinta iyo dahaarka, dhoobada gaarka ah

Faa'iidooyinka
0-1mm Alumina cad oo la isku daray oo aan la adkeyn karin
1. Adkayn sare iyo walxo cufan. Wareega hal qayb ayaa wanaagsan.
2. Midabku waa caddaan saafi ah, wax wasakh ah ma jiraan, si loo hubiyo in lakabka u adkaysta xirashada ama midabka warqadda u adkaysta xirashada iyo hufnaanta.
3. Qaybin isku mid ah oo cabbirka walxaha ah, qaab hal walxood ah oo isku mid ah, oo leh saameyn yar oo xirasho ah.
4. Xasiloonida kiimikada iyo aashitada, alkali ma shaqeynayo, xasilloonida heerkulka sare aad bay u fiican tahay.
1. Bacriminta ciidda, nadiifinta iyo shiididda birta iyo galaaska.
2. Buuxinta rinjiga, dahaarka aan xirashada lahayn, dhoobada, iyo dhalaalka.
3. Samaynta giraangiraha shiidi, warqadda ciidda iyo maro emery ah.
4. Soo saarista xuubka shaandhada dhoobada ah, tuubooyinka dhoobada ah, iyo saxannada dhoobada ah.
5. Loogu talagalay isticmaalka dabaqa aan xirnayn.
6. Bacriminta ciidda ee looxyada wareegga.
7. Bamgareynta maraakiibta, matoorada diyaaradaha, tareenada iyo jirkooda dibadda.
8. Noocyo kala duwan oo ah badarka aluminium oksaydh cad oo la isku daray ayaa la soo saari karaa iyadoo loo eegayo baahida macaamiisha ee kala duwan.
