Makonda a zirconia ceramic mikono ya semiconductors

Kufotokozera Kwachidule:

Zirconiaceramic

Zirconium oxide, yomwe imatchedwanso Zirconia, ndi ceramic yolimba kwambiri yokhala ndi kuuma kwa> 9 Mohs. Zirconia ili ndi mphamvu zapamwamba kwambiri komanso kulimba kwapang'onopang'ono pa kutentha kwapakati pakati pa zida zonse zapamwamba za ceramic, Kuphatikiza pa kupirira kuukira kwa chitsulo chosungunuka, zosungunulira za organic. , ma asidi amphamvu, ndi ma alkali amphamvu,sO zirconia ceramic ziwalo zimagwiritsidwa ntchito nthawi zonse muzochitika zosiyanasiyana zovuta.

Tsatanetsatane wa Zamalonda

Zolemba Zamalonda

Zirconia ndi chinthu chokhala ndi mphamvu zamakina apamwamba komanso kulimba kwapang'onopang'ono kutentha.Zirconia yathu (ZrO2) imawonjezeredwa ndi 3mol% Y2O3 zirconia yokhazikika (PSZ).Chifukwa tinthu m'mimba mwake wa zinthu PSZ ndi yaying'ono, izo zikhoza kukonzedwa ndi mwatsatanetsatane mkulu, ndi ntchito yake mwatsatanetsatane mbali Machining monga nkhungu kukula.Komanso, angagwiritsidwenso ntchito zida mafakitale, mbali kuwala cholumikizira ndi kuphwanya zida sing'anga.The mkulu fracture toughness PSZ angagwiritsidwe ntchito popanga akasupe apadera, ndipo amagwiritsidwanso ntchito kwambiri mipeni zoweta zadothi, slicer ndi mbali zina.

Zirconia (ZrO2) Ndimagwiritsa ntchito kwambiri

Zida za nkhungu ndi nkhungu (zoumba zosiyanasiyana, zoyika bwino, zosungirako);Zigawo zogaya (classifier, air flow mphero, mikanda mphero);Chida cha mafakitale (odula mafakitale, makina ophatikizira, opukutira atolankhani);Zida zolumikizira zamagetsi (mphete yosindikiza, manja, mawonekedwe a V-groove);Kasupe wapadera (coil spring, mbale kasupe);Zogulitsa za ogula (zotchinga zotchingira screwdriver, mpeni wa ceramic, slicer).
