Sikuti mafuta onse a zirconia omwe amapezeka pamalonda ali ofanana.Kusiyanitsa pakati pa zinthu za kukula kwa tirigu ndi zowonjezera kumawongolera kwambiri mphamvu ya zirconia block, kukhazikika kwanthawi yayitali, komanso kusinthasintha.
1. Komanso, njira zosiyanasiyana zomwe zirconia za mano zimapangidwira kuti zikhale zitsulo za zirconia za mphero zimakhudza kwambiri ubwino wa mankhwala omaliza.Unidirectional axial pressing imapanga mawonekedwe a mphero a zirconia block omwe ali olondola kwambiri koma alibe kusasinthasintha kwakuthupi kotero sikoyenera kukonzanso kwakukulu.
2. Komano, kuzizira kwa isostatic kukanikiza (CIP) kumagwiritsa ntchito sing'anga yamadzi, ngati madzi, kuti igwiritse ntchito mphamvu mofanana kumbali zonse ku ufa wa zirconia wotsekedwa mu nkhungu kuti ukhalebe mawonekedwe ake.
3. Zovuta kwambiri zomwe zimakhudzidwa ndi CIP zimachepetsa ndikuchotsa voids mu ufa kuti ziwonjezeke kachulukidwe kazinthu ndikupanga zobiriwira (zopanda malire) zirconia block ndi homogeneity yabwino kwambiri pazinthu zonse.Chotchinga cha green-state zirconia ndiye chokonzedweratu kuti chilole kuti chigayidwe mosavuta ndikusinthidwa ndi katswiri.Kupanga komaliza kumaphatikizapo kuyika zirconia kutentha kwambiri (1350 ° C mpaka 1500 ° C) pomwe kubwezeretsedwa komaliza kumawumitsa ndikuchepera pang'onopang'ono ndi 20% mpaka 25% kuti akwaniritse mphamvu zomwe zimafunikira komanso mawonekedwe owoneka bwino.
Mibadwo yoyamba ya zida zamphamvu kwambiri za CIP zirconia mphero zidapangitsa kubwezeretsedwa kwa monochromatic komanso kowoneka bwino komwe kumawonetsa kukongola kocheperako pokhapokha atasanjidwa.Komabe, pazaka 5 zapitazi, kusinthika kwatsopano kwa zida za zirconia block zasintha kukhala mphero za zirconia zomwe zikuyenda bwino kwambiri komanso midadada ya zirconia yokhala ndi mthunzi kapena midadada ya multilayer zirconia zomwe zimawonjezera kukongola kwinaku zimachepetsa kupanga.Phindu lalikulu pazida zowoneka bwinozi ndikuti zimafunikira kuchepetsedwa pang'ono kuposa kubwezeretsedwa kwa magalasi a ceramic-ceramic ndipo ndi okoma mtima ku mano achilengedwe otsutsana.
M'chaka chatha, mapangidwe atsopano a zirconia mphero adaphatikizapo omwe amatha kusungunula maola awiri okha.Monga opanga atatu apamwamba a zirconia ku China, chipika cha Yucera cha zirconia chimakwaniritsa zofunikira izi ndi njira yopangira pamwambapa, yomwe imatha kuthamangitsidwa mwachangu mu maola awiri pazifukwa zina mwachangu, pansi pa mayunitsi atatu a zirconia korona.Chotchinga cha zirconia block ndi multilayer zirconia block zimateteza bwino nthawi ya katswiri wamano ku mitundu yomwe yatsala pang'ono kufa, yoyenera kukonzanso kwanthawi yayitali.
Kodi mungagule kuti chipika cha zirconia cha mano?Mwamtheradi Yucera, talandirani tilankhule nafe.
