Kubadaha shiida ee alumina
Sharaxaada Alaabta
Kubadaha wax shiida ee alumina,oo lagu sameeyay aluminium oxide (Al₂O₃) oo ah qaybtooda xudunta u ah oo isticmaalaya habka sintering dhoobada, waa kubbado dhoobada shaqaynaya oo si gaar ah loogu talagalay shiididda, burburinta, iyo kala firdhinta alaabta. Waxay yihiin mid ka mid ah warbaahinta wax shiida ee inta badan loo isticmaalo codsiyada shiididda warshadaha (sida dhoobada, dahaarka, iyo macdanta).
Kubadaha wax lagu shiido alumina waxaa loo kala saaraa maadooyinkooda aluminium saddex nooc: kubbadaha aluminium dhexdhexaadka ah (60% -65%), kubbadaha aluminium-sare ee dhexdhexaadka ah (75% -80%), iyo kubbadaha aluminium sare (ka sarreeya 90%). Kubadaha aluminium-sare ayaa loo sii kala qaybiyaa 90-ceramic, 92-ceramic, 95-ceramic, iyo 99-ceramic, oo leh 92-ceramic oo ah midka ugu ballaaran ee loo isticmaalo sababtoo ah waxqabadkiisa guud ee sarreeya. Kubadaha wax lagu shiidi karo waxay ka kooban yihiin adkeysi sare (Mohs adkeyd of 9), cufnaanta sare (ka sarreeya 3.6g/cm³), xirashada iyo iska caabinta daxalka, iyo iska caabinta heerkulka sare (1600°C), taasoo ka dhigaysa inay ku habboon yihiin shiididda quraaradaha dhoobada ah, alaabta ceeriin kiimikaad, iyo macdanta birta ah.
Astaamaha:
Adayga Sare iyo Iska caabinta Dharka Xooggan:Adkeydka Mohs wuxuu gaaraa 9 (dheeman u dhow), oo leh heer gabbasho hooseeya (<0.03%/1,000 saacadood ee moodooyinka nadiifka sareeyo). Waxay ka hortagtaa burburka iyo burburka inta lagu jiro shiididda muddada dheer, taasoo keentay nolol adeeg oo dheer.
Cufnaanta Sare iyo Waxtarka Shiidaalka Sare:Iyada oo cufnaanta guud ee 3.6-3.9 g/cm³, waxay bixisaa saamayn xoog leh iyo xoog xiirid inta lagu jiro shiidi, si deg deg ah alaabta sifeeyo ilaa heerka micron, oo hufnaan 20% -30% ka sarreeya kubadaha aluminium-dhexe iyo heerka hoose.
Wasakhda Hoose iyo Deganaanshaha Kiimikada:Moodooyinka nadiifka sare leh waxay ka kooban yihiin wax ka yar 1% wasakh (sida Fe₂O₃), oo ka hortagaya wasakhowga walxaha. U adkaysta inta badan asiidhka iyo alkalis (marka laga reebo asiidh xoog leh iyo alkalis), heerkul sare (ka sarreeya 800 ° C), oo ku habboon hababka kala duwan ee wax lagu shiido.
Cabbirrada dabacsan iyo Waafaqid:Waxaa laga heli karaa dhexroorka 0.3 ilaa 20 mm, kubbadda waxaa loo isticmaali karaa hal cabbir ama cabbir isku dhafan, oo ku habboon miraha kubbadda, cammuudda, iyo qalabyada kale, oo daboolaya dhammaan baahiyaha laga bilaabo qallafsanaan ilaa si fiican u shiidi.
