ZrO2 Ceramic mipira

Mpira wa zirconia ceramic umagonjetsedwa ndi kutentha kwambiri ndipo umatha kugwira bwino ntchito m'malo otentha kwambiri pansi pa 1000 madigiri Celsius osasintha pang'ono. Ili ndi magwiridwe antchito otentha kwambiri, ndipo matenthedwe otenthetsa ndi 200-260 madigiri Celsius.

Ntchito kumunda: Makamaka ntchito yopanga ultrafine ndi kupezeka kwa kukhuthala mkulu ndi zipangizo mkulu kuuma pansi pa chilengedwe chimene chimafuna sterility ndi ziro kuipitsa;

Poyerekeza ndi mipira yachitsulo, zabwino zazikulu za mipira ya ceramic ndi:

(1) Ndi 59% yopepuka kuposa mipira yachitsulo, yomwe imachepetsa mphamvu ya centrifugal, kugubuduza ndi kumva kuwawa panjira yothamangayo pomwe chimbalangondo chikuyenda mwachangu;

(2) Modulus ya elasticity ndi 44% yayikulu kuposa yachitsulo, zomwe zikutanthauza kuti kuchuluka kwa mapindikidwe kumakhala kocheperako poyerekeza ndi mipira yachitsulo ikakakamizidwa;

(3) Kulimba ndikokwera kuposa chitsulo, HRC imafika 78;

(4) Coefficient of friction ndi yaying'ono, yopanda maginito, yamagetsi yamagetsi, komanso yolimbana ndi dzimbiri la mankhwala kuposa chitsulo;

(5) Kukwana koyerekeza kutentha kwamphamvu ndi 1/4 ya chitsulo, chomwe chitha kupirira kusintha kwadzidzidzi kutentha;

(6) Mapeto ake ali bwino, Ra amatha kufikira ma nanometers 4-6;

(7) Kutentha kwakukulu, mpira wa ceramic udakali ndi mphamvu komanso kuuma kwa 1050 degrees Celsius;

(8) Sichichita dzimbiri ndipo chitha kugwira ntchito mopanda mafuta.
