Chophika chopanda ndodo ndi chimodzi mwazinthu zazikulu kwambiri zomwe zapangidwapo m'munda wa zophikira, chifukwa zophikira zopanda ndodo zachepetsa kwambiri vuto la kuphika, ndipo azungu akukhitchini opanda chidziwitso chilichonse chophika amatha kuyamba kusonkhezera mbale bwino.
Monga tonse tikudziwa, khitchini yokhala ndi poto imodzi yokha yophika sikokwanira kuthana ndi zochitika zonse zophikira komanso osewera ophika.
Choncho, kulinganiza koyenera pakati pa kuphika kwathanzi ndi zokoma - poto yopanda ndodo, imakhala yabwino kusankha poto yopuma.
Masitepe:
1. Kukanikiza aluminiyamu kapena chitsulo chophatikizika mu mawonekedwe a nkhungu.
2. mutatha kuyeretsa, kuchitira pamwamba ndi sodium hydroxide kuti mupange voids yaying'ono kwambiri pamtunda wazitsulo.
3. Kupopera mphika wakunja wosanjikiza ndi enamel wosanjikiza ndi lacquer ndi sintering pa kutentha kwambiri (pafupifupi 560 ° C) mpaka chonyezimira.
4. Pansi pa mphika wamkati wamkati mwa mphika wopoperapo poyambira ndi zokutira zopanda ndodo, kutentha kwambiri (pafupifupi 425 ℃) sintering, poto yopanda ndodo kuchokera mu uvuni.
