Khoom Taw qhia
Alumina ceramic washers muaj cov cuab yeej siab zog, siab hardness, tsis tshua muaj ntau qhov hluav taws xob dielectric poob, qhov kub tsis kam, siab hluav taws xob rwb thaiv tsev thiab tsis kam, thiab zoo tshuaj corrosion kuj. Tsis tas li ntawd, tus nqi ntawm alumina txuas ntxiv yog ntau dua tus nqi ntawm silicon carbide, silicon nitride, thiab zirconia. UNIPRETEC muaj ntau yam txhuas aluminium oxide ceramic txuas rau ntau qib qib uas muaj cov yam ntxwv sib txawv, tuaj yeem hloov kho los ntawm hom phiaj tsim qauv. Alumina ntawm ntau yam kev ua kom dawb huv (Al2O3) yog siv ntau dua li lwm cov khoom siv tshaj ceramic, thiab kev muag khoom kuj nyob hauv thawj qhov chaw hauv cov khoom lag luam zoo nkauj, uas qhia tau pom dav dav ntawm Al2O3 tej hub txuas hauv ntau qhov kev lag luam.
