Leben badan
Ku saabsan bulukeetiyada badan
Lebenka mullite waa aluminium sare oo celinaya oo leh mullite oo ah wejiga ugu weyn ee crystal.Guud ahaan, waxa ku jira aluminiumku waa inta u dhaxaysa 65% iyo 75%.Marka lagu daro mullite, macdanta leh maadada aluminiumka hoose waxay sidoo kale ku jiraan qadar yar oo ah wajiga vitreous iyo cristobalite.Waxa ku jira aluminium sare waxa kale oo ku jira qadar yar oo corundum ah.
Lebenka badan ayaa leh refractory sare, kaas oo gaari kara in ka badan 1790 °C.Heerkulka bilawga jilcintu waa 1600 ℃ 1700 ℃.Awoodda cadaadiska ee heerkulka qolka waa 70-260MPa.Iska caabbinta shoogga kulaylka wanaagsan.
Waxaa jira laba nooc oo leben leben ah oo isku dhafan iyo leben isku dhafan.
Lebenka mullite-ka ah ee la jeexjeexay ayaa laga sameeyay clinker-alumina bauxite clinker oo ah alaabta ceeriin ee ugu weyn, iyadoo lagu darayo qadar yar oo dhoobo ah ama bauxite cayriin sida binder, oo la sameeyay oo la shido.Lebennada isku dhafan ee mullite-ka ah waxay ka samaysan yihiin bauxite sare, alumina warshadaha iyo dhoobada refractory, iyo walxaha dhuxusha ama kookaha ayaa lagu daraa sida wakiilka yareynaya.Ka dib qaabeynta, waxaa lagu soo saaraa iyadoo la dhimayo koronto-siinta.
Kiraysinta mullite-ka la isku daray way ka weyn tahay tan mullite-ka sintered, iyo iska caabbinta shoogga kulaylka ayaa ka fiican kan alaabooyinka sintay.Waxqabadkooda heerkul sare waxay inta badan ku xiran tahay waxa ku jira aluminium iyo isku mid ahaanshaha qaybinta wejiga iyo dhalooyinka.
Lebenka badan ayaa inta badan loo isticmaalaa shooladda sare ee qaraxa kulul, foornada qarxinta jirka iyo hoose, dib-u-kicinta foornada dhalada, foornada dhoobada, dahaarka geeska dhintay ee nidaamka dildilaaca batroolka, iwm.
Ku saabsan Sillimanite
Lebenka sillimanite waxay leeyihiin xasilloonida kulaylka wanaagsan ee heerkulka sare, iska caabinta nabaad-guurka dareeraha galaaska, wasakh yar ilaa dareeraha galaaska.
Inta badan waxay ku habboon tahay kanaalka quudinta, mashiinka quudinta, mashiinka jiidista tuubada iyo qalabyada kale ee warshadaha galaaska, kuwaas oo si weyn u wanaajin kara wax soo saarka.
