Ubushyuhe bwo hejuru bwububumbyi

Deqing Yehui Ceramic Parts Manufacture Co., Ltd. iherereye mu ntara ya Deqing, Umujyi wa Huzhou, Intara ya ZheJiang, mu Bushinwa.Nibirometero 200 uvuye ku cyambu cya Shanghai specialized twabigize umwuga wo gukora Zirconia Ceramics na Alumina Ceramic ibice hamwe nimyaka 10.

Ubushyuhe bwo hejuru bwo kurwanya ubukerarugendo bwubatswe ni bwiza muri rusange ni byiza, ubusanzwe buri munsi ya 800 ° C, kandi ubushyuhe ntibuhindura cyane imbaraga zibikoresho byubutaka.Ugereranije na covalent bond ceramics, ceramics ion-ihujwe nubutaka bufite ubukana buke bwo hejuru.Muri rusange, mubushyuhe bwo hasi, kunanirwa kuvunika kumubumbyi ni imyitwarire idahwitse, ni ukuvuga ko nta deformasique ihari, kandi imbaraga zanyuma ni nto cyane, kandi yunvikana cyane nudusimba duto.Nyamara, mu bushyuhe bwo hejuru, ubukerarugendo bushobora kubyara plastike ntoya mbere yo kuvunika, imbaraga ziyongera cyane, kandi hariho imyitwarire mike ya elastoplastique.Byongeye kandi, kumva imbaraga zinenge biratandukanye cyane.Imipaka iri hagati yubushyuhe buke nubushyuhe bwo hejuru butanga iyi mpinduka yibintu mubisanzwe byitwa ubushyuhe bwimyanya ihindagurika.Ubushyuhe bwimyanya ihindagurika bifitanye isano rya bugufi nubutaka bwa ceramic hamwe nubwoko bwa valence.Bifitanye isano, ariko kandi bifitanye isano na microstructure ya ceramic, ibigize icyiciro cyimbibi zintete, cyane cyane ibigize nibiri mubice byimbibi byikirahure.Ku bushyuhe bwinshi, hejuru yubushyuhe bwimyanya ihindagurika, imbaraga zibikoresho byinshi byubutaka bizagabanuka.Kubutaka bwa ion-MgO ceramics, ubushyuhe bwinzibacyuho yubushyuhe buri hasi cyane, kandi imbaraga ziragabanuka hamwe no kwiyongera kwubushyuhe hafi yubushyuhe bwicyumba.Ubushyuhe bwimyanya yubushyuhe bwa Al2O3 bugera kuri 900 ° C, ubushyuhe bwimihindagurikire yubushyuhe bwikigereranyo cyashyushye Si3N4 bugera kuri 1200 ° C, nubutaka bwa SiC burashobora kwihanganira ubushyuhe bwinshi bwa 1600 ° C.
