Calcined Alumina
Calcined Alumina waa Alumina ganacsi ama Aluminum Oxide. Waa budo cad. Mid ka mid ah sifooyinka fiican oo Calcined Alumina waa darantahay ingeega, taas oo ah 9 on baaxadda Mohs. Waxaa jira beerta guddiga warshadaha ee codsiyada noocan ah alumina iyo tirada fasalka kala waxaa la soo saaray si loo daboolo baahiyaha kala duwan.
Aqoonsiga fasalada
1) Calcined Aluminum S-100 fasalada: White budo la barwaaqaysan granular free maraa 150 m.
2) Calcined Aluminum S-300 fasalka: budada superfine White maraa in kastoo 45 micron.
3) fasalka Calcined Alumina SCM: Waa fasalada ugu dambeyntii dhulka ka kooban oo gebi of superfine maraa 45 micron.
Fasalka Waxaa Barandho dhulka ka kooban oo gebi of superfine la dusha loola dhaqmo: 4) Calcined Alumina S-300 PT.
Isticmaala
Isticmaal qalab gogosha in daaweyn kulaylka of steels daawaha gaarka ah ee a, Waa isticmaalaan sida dhexdhexaad fluxing in kulanka steels gaar ah sida qayb ka mid ah galaas ballaarinta hooseeya. Waxaa la isticmaali sida dastuurka ah ee china gaar ah dazes & waa isticmaalka qalab dihin for soo saaridda ee porcelains ilkaha. Waa isticmaali codsiga madax adkaadeen sida insulators korontada. Waa isticmaalaan sida a adkaysi u sugi lahaayeen. Waa isticmaali mirayadahiisa dusiyeen dhoobada.
Nooc gaar ah A ee Alpha alumina calcined.
Sida kaamerada polymer filler ningax, waxaa si weyn loo isticmaalaa in conductivity kaamerada of balaastigga, caag, adhesives iyo blaastiigga.
