Calcined Alumina Ultrafine ee Dib-u-soo-celinta Waxqabadka Sare, waxaa loo isticmaali karaa kabka leh qiiqa silica iyo budada alumina ee fal-celinta, si loo yareeyo ku darida biyaha, porosity iyo in la kordhiyo xoogga, xasilloonida mugga.

Darajada dhoobada- Alumina-ka-salaysan

Alaabooyinka alumina ee leh budada alumina ee calcined sida alaabta ceeriin waxay leeyihiin xoog farsamo oo aad u fiican, qallafsanaan sare, iska caabin koronto oo sarreeya iyo kuleylka kuleylka wanaagsan. Micropowder alumina calcined waxaa si ballaaran loogu isticmaali karaa qalabka elektarooniga ah, ceramics qaab dhismeedka, refractories, abrasives, alaabta polishing, iwm

Calcined aluminas waa alfa-alumina kuwaas oo ka kooban ugu horrayn agglomerates sintered ee crystals aluminium shaqsi. Baaxadda kiristaalo kuwan aasaasiga ah waxay ku xiran tahay heerka calcination-ka iyo cabbirka agglomerate ee tillaabooyinka shiida ee xiga. Inta badan aluminium calcined waxaa la bixiyaa dhul (<63μm) ama dhul wanaagsan (<45μm). Agglomerates si buuxda looma jabin inta lagu jiro shiididda, taas oo ah farqi weyn oo ka yimid aluminas fal-celin ah oo si buuxda u dhulka u ah habka wax shiididda dufcaddii. Aluminiinta la kariyey waxaa lagu kala saaraa maadada soodhaha, cabbirka walxaha iyo heerka calcination. Aluminiinta dhulka iyo dhulka fiican ayaa loo isticmaalaa sidii buuxinta matrixka si loo cusboonaysiiyo wax qabadka wax soo saarka ee inta badan ku salaysan alaabta ceeriin ee dabiiciga ah.

Calcined aluminas waxay leeyihiin cabbir qaybo la mid ah isku-darka macdanta dhulka oo sidaas darteed si fudud ayey ugu beddeli karaan isku-darka nadiifinta hoose. Iyada oo la kordhinayo nuxurka guud ee alumina ee isku dhafka iyo hagaajinta xirmooyinkooda walxaha iyada oo lagu darayo alumina wanaagsan, dib-u-celinta iyo sifooyinka farsamada, sida moodooyinka kulul ee dillaaca iyo iska caabbinta abrasion, ayaa la wanaajiyey. Baahida biyaha ee aluminium calcined waxaa lagu qeexaa cadadka agglomerates haraaga ah iyo bedka dushiisa. Sidaa darteed, aluminium-ka-salaysan ee leh meel sare oo hooseeya ayaa la door bidaa buuxinta lebenka iyo kabka. Alumina-yada gaarka ah ee la kariyey ee leh bed sare, waxay si guul leh u bedeli karaan dhoobada sida balaastikada ee qoryaha iyo isku darka. Alaabooyinka refractory ee ay wax ka beddeleen alaabooyinkani waxay ilaalinayaan sifooyinkooda rakibida wanaagsan laakiin waxay muujinayaan hoos u dhac weyn ka dib qallajinta iyo rasaasta.
