Xoogga heerkulka sare ee ceramics

Deqing Yehui Ceramic Parts Manufacture Co., Ltd. waxay ku taal degmada Deqing, Huzhou City, Gobolka ZheJiang, Shiinaha.Waxay ku saabsan tahay 200km ka fog dekedda Shanghai, waxaan ku takhasusay soo saarista Ceramics Zirconia iyo Alumina Ceramic qaybo leh 10 sano.

Iska caabinta heerkulka sare ee dhoobada qaab dhismeedka ayaa guud ahaan ka wanaagsan, badanaaba ka hooseeya 800 ° C, heerkulku saameyn yar ayuu ku leeyahay xoogga alaabta dhoobada.Marka la barbar dhigo ceramics bond bond, dhoobada ion- bonded ayaa leh iska caabin heerkul sare oo liita.Guud ahaan, heerkulka hoose ee kala duwan, jabka jabka ee ceramics waa dabeecad jilicsan, taas oo ah, ma jiraan wax balaastig ah, iyo cadaadiska ugu dambeeya waa mid aad u yar, oo aad u nugul cilladaha yaryar.Si kastaba ha noqotee, aagga heerkulka sare, ceramics waxay soo saari kartaa cillad yar oo balaastik ah ka hor inta aan la jabin, cadaadiska ugu dambeeya ayaa si weyn u kordhay, waxaana jira qadar yar oo ah dabeecadda elastoplastic.Intaa waxaa dheer, dareenka xoogga cilladaha aad ayey u kala duwan tahay.Soohdinta u dhaxaysa aagga heerkulka hooseeya iyo aagga heerkulka sare ee soo saara isbeddelka alaabtan waxaa badanaa loo yaqaan heerkulka kala-guurka ductility ee jajaban.Heerkulka kala-guurka ductility ee jajaban wuxuu si dhow ula xiriiraa isku dhafka kiimikada dhoobada iyo nooca valence bond.Laxiriira, laakiin sidoo kale laxiriira qaab-dhismeedka yar-yar ee dhoobada, halabuurka wejiga xadka hadhuudhka, gaar ahaan halabuurka iyo nuxurka wajiga galaaska xadka hadhuudhka.Heerkulka sare, oo ka sarreeya heerkulka kala-guurka ductility, xoogga alaabta dhoobada ah ayaa yaraan doonta.Wixii dhoobada MgO-ku-xidhan, heerkulka kala-guurka ductility ee jaban aad buu u hooseeyaa, xoogguna wuu yaraadaa kororka heerkulka ku dhawaad ​​heerkulka qolka.Heerkulka kala-guurka ductility-ga ee Al2O3 wuxuu ku saabsan yahay 900 ° C, heerkulka kala-guurka ductility-ga dillaacsan ee saxafada kulul ee Si3N4 waa qiyaastii 1200 ° C, iyo ceramics-ka SiC waxay inta badan u adkeysan kartaa heerkul sare oo ah 1600 ° C.
