Zirconia yog ib yam khoom uas muaj zog txhua yam thiab tawg toughness ntawm chav tsev kub. Peb zirconia (ZrO2) ntxiv nrog 3mol% Y2O3 ib nrab ruaj khov zirconia (PSZ). Vim hais tias cov particle txoj kab uas hla ntawm PSZ cov khoom yog me me, nws muaj peev xwm ua tiav nrog high precision, thiab nws daim ntawv thov nyob rau hauv precision machining qhov chaw xws li pwm yog expanding. Tsis tas li ntawd, kuj tuaj yeem siv rau kev lag luam cov cuab yeej, kho qhov muag connector qhov chaw thiab crushing khoom nruab nrab. Lub siab tawg toughness ntawm PSZ yuav siv tau los ua tshwj xeeb springs, thiab nws kuj yog lug siv nyob rau hauv domestic ceramic riam, slicer thiab lwm yam.
Zirconia (ZrO2) Kuv siv lub ntsiab
Pwm thiab pwm cov cuab yeej (ntau yam pwm, precision positioning fixture, rwb thaiv tsev fixture); Mill qhov chaw (classifier, cua ntws zeb, hlaws zeb); Cov cuab yeej muaj (kev lag luam cutter, slitter tshuab, ca xovxwm yob); Optical connector Cheebtsam (lub nplhaib sealing, lub tes tsho, V-groove fixture); Caij nplooj ntoos hlav tshwj xeeb (coil caij nplooj ntoos hlav, phaj caij nplooj ntoos hlav); Cov khoom siv (me me insulated screwdriver, ceramic riam, slicer).
