Kodi magawo atatu osiyana a sintering a alumina ceramics ndi ati? Sintering ndi njira yayikulu ya alumina ceramics yonse popanga, ndipo kusintha kosiyanasiyana kudzachitika isanayambe komanso itatha sintering, Xiaobian yotsatirayi idzayang'ana kwambiri magawo atatu osiyana a sintering a alumina ceramics:
Choyamba, musanachite kuipitsa, kuwongolera kutentha pa siteji iyi ndikofunikira kwambiri, chifukwa kutentha kumapitirira kukwera, mwana wosabadwayo adzachepanso, koma mphamvu ndi kuchulukana sizisintha kwambiri, ngati ndi zazing'ono kwambiri, njere sizisintha kukula, koma mwana wosabadwayo pa siteji iyi amakhala ndi vuto la ming'alu, makamaka chifukwa chomangirira ndi madzi zimatulutsidwa kwathunthu, kotero tiyenera kulabadira liwiro la kukwera kwa kutentha.
Chachiwiri, mu ndondomeko yochotsa madzi m'thupi, kutentha kudzasintha pang'ono, thupi la mwana wosabadwayo limachepa pang'onopang'ono, ndipo kuchulukana kudzasintha kwambiri. Ngakhale kuti palibe kusintha koonekeratu mu tinthu tating'onoting'ono, tinthu tonse sitikugwirizananso, ndipo ma pores onse adzakhala ochepa. Mofananamo, chifukwa thupi la mwana wosabadwayo limasintha voliyumu, zimakhala zosavuta kuoneka ngati kusintha kwa masinthidwe ndi kusweka kwa mabakiteriya.
Chachitatu, potsiriza, kutentha kudzakwera kwambiri, thupi la mwana wosabadwayo ndi kuchulukana kwake zidzasintha kwambiri, kusintha kwa tirigu mu micro kumawonekeranso bwino, ma pores adzakhala ochepa, mapangidwe a ma pores ambiri olekanitsidwa, koma padzakhala ma pores ena otsala mwachindunji pa tirigu.
