Zida za ceramic zokhala ndi mizere zimagwiritsidwa ntchito kwambiri pamankhwala, mphamvu, zitsulo ndi madera ena chifukwa cha kukana kwawo kutentha kwambiri, kukana dzimbiri komanso kukana kuvala. Njira yopanga ndi yovuta komanso yosasunthika, yomwe imaphatikizapo maulalo angapo ofunikira kuti zitsimikizire kukhazikika kwapamwamba komanso kukhazikika kwa chinthu chomaliza. Nkhaniyi ifotokoza njira yayikulu yopangira zinthu zadothi zadothi mwatsatanetsatane.
Kukonzekera zakuthupi ndi kusakaniza
Kupanga zinthu zopangidwa ndi mizere ya ceramic kumayamba ndi kusankha ndi kugawa kwazinthu zopangira. Zopangira zazikuluzikulu ndi monga mkulu-alumina wa purity, zirconium oxide, silicon carbide ndi ufa wina wa ceramic, womwe ndi wolimba kwambiri, wosasunthika kutentha komanso kusasunthika kwa mankhwala. The zipangizo ayenera mosamalitsa kufufuzidwa kuonetsetsa kuti chiyero ndi tinthu kukula kukwaniritsa zofunika. Pambuyo pake, zida zosiyanasiyana zopangira zimasakanizidwa mugawo linalake, ndipo kuchuluka koyenera kwa binder (monga zomatira organic kapena zinthu zomangira zomangira) kumawonjezedwa kuti kumapangitsanso mphamvu ndi kukhazikika pambuyo pakuumba. Kusakanizako nthawi zambiri kumagwiritsa ntchito zida zapamwamba-zothamangitsa mwachangu kuti zitsimikizire kuti zopangira zigawidwa mofanana.
Kuumba ndondomeko
Ufa wosakanizidwa wa ceramic uyenera kupangidwa kukhala mawonekedwe ofunikira kudzera munjira yowumba. Njira zodziwika bwino zomangira zimaphatikizapo kukanikiza kowuma, kukanikiza kwa isostatic ndi kuponyera. Kukanikiza kowuma ndikoyenera kwa zinthu zokhala ndi mawonekedwe osavuta, omwe amapanikizidwa ndikupangidwa mopanikizika kwambiri kudzera mu nkhungu; kupondereza kwa isostatic ndikoyenera kwa zomangira zovuta, zomwe zimagwiritsa ntchito kuchuluka kwa-kuthamanga kwamadzimadzi kuti agwiritse ntchito mofanana kuti awonjezere kachulukidwe ndi mphamvu ya chinthucho; jekeseni wa slip amagwiritsidwa ntchito kwambiri pazigawo zazikulu kapena zapadera-zooneka bwino, ndipo matope a ceramic amabayidwa mu nkhungu, ndipo thupi lobiriwira limapangidwa madzi akasungunuka.
Sintering ndi kutentha mankhwala
Thupi lobiriwira lopangidwa liyenera kutenthedwa kutentha kwambiri kuti liphatikize tinthu tating'onoting'ono ta ceramic kukhala cholimba. Kutentha kwa sintering nthawi zambiri kumakhala pakati pa 1600 digirii ndi 1800 digiri, kutengera mtundu wa zinthu zadothi. Mkati mwa sintering, thupi lobiriwira limafota ndi kupanga-mphamvu ndi kulimba-thupi ladongo lolimba. Zogulitsa zina zimafunikiranso chithandizo cha kutentha, monga kutsekereza kapena kulimbikitsa pamwamba, kuti zipititse patsogolo magwiridwe antchito.
Chithandizo cha pamwamba ndi kuyezetsa
Pambuyo pa sintering, zinthu za ceramic ziyenera kuchitidwa pamwamba, monga kupukuta, kupaka kapena kuyika mbali zachitsulo kuti zikwaniritse zofunikira zenizeni. Pomaliza, chinthucho chikuyenera kuyesedwa bwino kwambiri, kuphatikiza muyeso wowoneka bwino, kuyezetsa kuuma, kuwunika kukana kwa dzimbiri, ndi zina zambiri, kuti zitsimikizire kuti zikutsatira miyezo yamakampani.
Njira yopangira zinthu za ceramic yokhala ndi mizere imaphatikizapo kuphatikiza kwa sayansi ndiukadaulo waukadaulo. Ubwino wake wapamwamba komanso magwiridwe antchito apamwamba zimapangitsa kuti ikhale gawo lofunikira kwambiri pamafakitale.
