Khoom Taw qhia
Aluminium oxide ceramic nrog nws ntau qib ntawm purity yog cov khoom siv dav siv ntau tshaj plaws. Alumina oxide ceramic muaj qhov nyuaj thiab lub zog thiab muaj cov thermal thiab tshuaj lom neeg zoo. Tsis tas li ntawd, cov hluav taws xob zoo heev ntawm aluminium oxide ceramic yog qhov tseem ceeb rau kev lag luam. Peb txheej txheem aluminium oxide alumina hmoov nrog Al2O3 cov ntsiab lus xws li 90% txog 99.8%. Raws li tus qauv, txhuas oxide Al2O3 muaj nyob rau hauv dawb thiab kaus ntxhw. Los ntawm kev ntxiv, uas ua haujlwm rau cov cuab yeej optimization, kuj muaj xim sib txawv tuaj yeem muab tau.

Txoj Kev Loj Hlob
Raws li cov khoom siv dav tshaj plaws hauv ceramics siab heev, aluminium oxide alumina ceramics nthuav tawm cov kev txhim kho hauv qab no nrog rau kev txhim kho tag nrho kev lag luam. (1) Cov khoom siv thev naus laus zis yuav nce nrawm nrawm: kev tsim kho tshuab computer thiab digital tswj tshuab txhawb nqa kev lag luam ceramic khoom siab heev; Kev txhim kho thev naus laus zis thiab kev loj hlob sai ntawm kev lag luam, kev ua tiav tiav ntawm cov cuab yeej xws li kev tswj tsis tu ncua ntawm cov sintering kilns, siab - zog thiab loj - muaj peev xwm sib tsoo cov cuab yeej, siab - cov khoom siv hmoov thiab granulation thiab lwm yam khoom siv net pressure forming tau txais txiaj ntsig zoo txhawb kev txhim kho tag nrho qib ntawm kev lag luam; Cov khoom siv tau zoo thiab cov khoom lag luam zoo kuj tau txhim kho tau zoo. (2) Cov qib zoo ntawm cov khoom siv txhuas oxide tau raug txhim kho tas li: cov khoom siv microcrystalline alumina ceramic tau loj hlob los ntawm kos, cov nplais kev lag luam tau loj hlob los ntawm me me mus rau qhov loj, thiab cov khoom zoo tau ploj mus los ntawm qhov qis mus rau qhov siab. (3) Cov nplai ntawm kev lag luam yuav nthuav dav sai: raws li cov khoom siv tseem ceeb ntawm lwm cov kev lag luam lossis kev lag luam, microcrystalline alumina ceramic cov khoom raug cuam tshuam thiab txwv los ntawm qib kev loj hlob ntawm lwm cov lag luam. Los ntawm kev xav ntawm daim ntawv thov ntawm alumina ceramics, daim ntawv thov ntau yog dav thiab dav, thiab tus nqi nce.
