Menene matakai guda uku daban-daban na sintering na alumina yumbura? Sintering babban tsari ne na dukkanin yumbu alumina a cikin masana'antu, kuma sauye-sauye daban-daban za su faru kafin da kuma bayan sintering, Xiaobian mai zuwa zai mai da hankali kan matakai daban-daban na sintering uku na yumbu alumina:
Na farko, kafin yin gyare-gyare, kula da zafin jiki a wannan mataki ya fi muhimmanci, saboda zafin jiki ya ci gaba da karuwa, tayin kuma zai yi raguwa, amma ƙarfin da yawa ba zai canza da yawa ba, idan yana da microscopic, hatsi ba zai canza girmansa ba. , amma amfrayo a wannan mataki ya fi dacewa da fashewar sabon abu, Musamman saboda abin da aka cire da ruwa gaba daya, don haka dole ne mu kula da saurin hawan zafin jiki.
Na biyu, a cikin tsarin ɓacin rai, zafin jiki zai canza kaɗan kaɗan, jikin tayin yana raguwa a hankali, kuma yawan zai canza sosai. Ko da yake babu wani canji na zahiri a cikin ƙananan ƙwayar ƙwayar cuta, duk barbashi ba su da alaƙa da gaske, kuma gabaɗayan pores za su zama ƙarami da ƙarami. Hakazalika, saboda jikin amfrayo yana da canji a cikin girma, Don haka har yanzu yana da sauƙin bayyana nakasawa da fashewar sabon abu.
Na uku, a ƙarshe, bayan sintering, yawan zafin jiki zai tashi sosai, jikin amfrayo da yawa za su fuskanci manyan canje-canje, canjin hatsi a cikin micro kuma ya fi dacewa, pores zai zama karami, samuwar pores da yawa, amma za a sami wasu pores kai tsaye saura akan hatsi.
