Calcined Alumina Ultrafine Loogu talagalay Dib-u-soo-celinta Waxqabadka Sare

Budada aluminium ee calcined waxaa lagu sameeyaa xisaabinta tooska ah ee alumina warshadaha ama aluminium hydroxide heerkulka saxda ah si loogu beddelo crystallinea-alumina deggan, ka dibna shiiddo budo-yar.Budada yar-yar ee calcined waxaa loo isticmaali karaa albaabka slide, nozzles, iyo lebenka aluminiumka.Intaa waxaa dheer, waxaa loo isticmaali karaa in castables leh qiiqa silica iyo budada alumina falcelinta, si loo yareeyo ku darida biyaha, porosity iyo in la kordhiyo xoogga, xasilloonida mugga.

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.

Aluminium Calcined

Aluminas Calcined ee Refractories

Sababo la xiriira sifooyinka heerkulka sare ee a-Alumina, Calcined Aluminas waxaa loo isticmaalaa codsiyo badan oo dib u celin ah, labadaba alaabada monolithic iyo qaabaysan.

Waxqabadka Alaabta
Iyada oo ku xidhan heerka wax-shiidka iyo cabbirka crystal, Calcined Aluminas waxay u adeegtaa hawlo kala duwan oo kala duwan qaab-dhismeedka.

Kuwa ugu muhiimsan waa:
• Kor u qaadida waxqabadka badeecada iyadoo la kordhinayo guud ahaan maadada alumina ee qaab-dhismeedkan iyadoo la isticmaalayo alaabta ceeriin ee dabiiciga ah si loo hagaajiyo dib-u-celinta iyo sifooyinka farsamada.
• Hagaajinta xidhidhiyaha walxaha adiga oo kordhinaya cadadka qurubyada ganaaxa taasoo keenaysa xoog farsamo oo wanaagsan iyo caabbinta naaxinta.
• Samee jaantus ah refractorness sare iyo caabbinta kulaylka wanaagsan adigoo ka falcelinaya qaybaha xiraha sida Calcium Aluminate Cement iyo / ama dhoobada.
