Kodi ndi zinthu ziti zomwe zimakhudza ubwino wa matailosi a Alumina Ceramic?

1. Mphamvu ya ufa wa zinthu zopangira

Zipangizo zofunika kwambiri zopangira alumina zosagwirizana ndi kutopa ndi ufa wa alumina woyera kwambiri. Kagwiridwe kake ndi kuchuluka kwake zimakhudza kwambiri zidole za alumina zosagwirizana ndi kutopa. Ufa wa ceramic mosakayikira udzayambitsa zinyalala panthawi yokonzekera, ndipo zinyalala za organic zidzawotchedwa panthawi yopangira sintering, ndikupanga ma pores osakhazikika panthawi yopangira sintering; zinyalala zopanda chilengedwe zidzagwirizana ndi ufa wa ceramic pa kutentha kwakukulu kapena mu matrix Kupanga kwa ma microcracks. Zinyalala izi zimakhudza kwambiri kuchuluka kwa zidole za alumina. Kukula kwa tinthu ta ufa wa zinthu zopangira kumakhudzanso kwambiri magwiridwe antchito a chinthucho. Pokhapokha ngati zinthuzo zili bwino, chinthu chomaliza chopangidwa ndi sintered chingapange kapangidwe ka microcrystalline, zomwe zimapangitsa kuti chikhale ndi kukana bwino kutopa. Chifukwa chake, ufa wa alumina woyera kwambiri, wokhala ndi tinthu tating'onoting'ono ndi chofunikira kwambiri pakukonzekera zidole za alumina zosagwirizana ndi kutopa.

 2. Mphamvu ya njira yopangira zinthu

Machitidwe opanga zinthu ndi kafukufuku wambiri wasonyeza kuti zoumba za alumina zokhala ndi ma porosity ochepa komanso zolemera kwambiri zili ndi mawonekedwe abwino kwambiri. Kulemera kwambiri kumatanthauza kuti tinthu ta kristalo m'thupi la zoumba zimayikidwa bwino, ndipo sikophweka kupanga malo owononga zinthu zikamakumana ndi zinthu zachilengedwe zakunja kapena zinthu zowononga.

Kuti mupeze njira yopangira thupi la ceramic yolimba kwambiri ndikofunikira. Ma ceramic osagwiritsidwa ntchito ndi alumina nthawi zambiri amatha kupangidwa ndi dry press, isostatic pressing, hot die casting ndi njira zina. Njira zosiyanasiyana zopangira zinthu zimakhala ndi makhalidwe osiyanasiyana ndipo zimakhudzanso zinthu zosiyanasiyana pa sintering ndi microstructure ya alumina ceramics.

Zinthu zokhala ndi mawonekedwe osiyanasiyana nthawi zambiri zimakonzedwa pogwiritsa ntchito grouting kapena hot-press casting, ndipo zinthu zokhala ndi mawonekedwe osavuta zimapangidwa ndi dry press.

 3. Mphamvu yoyeretsera

Kupaka utoto ndi gawo lofunika kwambiri pakukonzekera zinthu zadothi, ndipo mlengalenga wopaka utoto umakhudza kwambiri kukonzekera zinthu zadothi. Kutentha kwambiri kapena nthawi yayitali yogwira ntchito kumathandizira kukula kwa makhiristo, zomwe zimapangitsa kuti zinthu zabwino zikhale zosalala pa kutentha kwambiri, ndipo kuchuluka kwa madzi m'gawo ladothi kudzawonjezeka. Izi sizingochepetsa mphamvu zokha, komanso zimachepetsa kukana kuwonongeka. Zachidziwikire, ngati kutentha kuli kotsika kwambiri, thupi lopaka utoto silidzakhala lolimba, ndipo kukana kuwonongeka kwa chinthucho sikudzakhala bwino.

 Kuwotcha ng'anjo yamagetsi bwino kwambiri kumatha kuwongolera bwino momwe kutentha, kugwira ndi kuziziritsira zimagwirira ntchito, zomwe zimathandiza kwambiri pakukweza kukana kwa zinthu zadothi, koma mtengo wowotcha ndi kugwiritsa ntchito zinthu zotsutsana ndi utsi wamagetsi ndi wokwera kuposa wa migodi ya malasha.

4. Chowonjezera kuyaka

Kupaka koyenera kumathandiza kuchepetsa kutentha panthawi yopaka, kukonza kapangidwe kake ka zinthu zadothi, ndikukonzanso mawonekedwe a makina, motero kumathandizira kukana kuwonongeka kwa zinthu zadothi zosagwirizana ndi alumina.

 Wopanga CHEMSHUN ceramic amasamala kwambiri zamatailosi a alumina ceramic opangidwa ndi ceramickhalidwe la kupanga. Takulandirani ku mafunso.
