Kodi magawo atatu a sintering a alumina ceramic ndi ati? Sintering ndi njira yayikulu yopangira zida zonse za aluminiyamu popanga, ndipo zosintha zambiri zizichitika zisanachitike komanso zitatha, Xiaobian amayang'ana magawo atatu osiyanasiyana a alumina ceramics:
Choyamba, musanayambe sintering, kutentha kwa kutentha panthawiyi ndikofunika kwambiri, chifukwa kutentha kumapitirirabe, mwana wosabadwayo adzachepa, koma mphamvu ndi kachulukidwe sichidzasintha kwambiri, ngati ndi yaying'ono, njere sizingasinthe kukula kwake. , koma mluza pa siteji imeneyi ndi sachedwa akulimbana chodabwitsa, makamaka chifukwa binder ndi madzi kwathunthu kutulutsidwa, choncho tiyenera kulabadira liwiro la kutentha kukwera.
Chachiwiri, mu ndondomeko ya sintering, kutentha kudzasintha pang'ono matalikidwe, thupi la mwana wosabadwayo limachepa pang'onopang'ono, ndipo kachulukidwe kadzasintha kwambiri. Ngakhale kuti palibe kusintha koonekeratu mu njere zazing'ono, tinthu tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono timakhala tating'onoting'ono. Mofananamo, chifukwa thupi la mwana wosabadwayo ali ndi kusintha voliyumu, Choncho akadali zosavuta kuoneka mapindikidwe ndi akulimbana chodabwitsa.
Chachitatu, potsiriza, pambuyo sintering, kutentha adzauka kwambiri, mluza thupi ndi kachulukidwe adzakhala ndi kusintha kwakukulu, kusintha kwa njere mu yaying'ono ndi zoonekeratu kwambiri, pores adzakhala ang'onoang'ono, mapangidwe ang'onoang'ono pores, koma padzakhala ena pores mwachindunji zotsalira pa njere.
