Tsis ntev los no, nrog rau kev nce ntxiv ntawm qhov tob thiab qhov muaj zog ntawm kev khawb av, qhov teeb meem ntawm kev hnav cov khoom siv tau dhau los ua qhov tseem ceeb dua. Kev tshwm sim ntawm alumina hnav-resistant ceramics tau coj kev cia siab tshiab rau kev lag luam khawb av.
Hauv ib lub qhov av loj, cov khoom siv thauj khoom thiab cov khoom sib tsoo yav dhau los tau hloov pauv ntau zaus vim muaj kev cuam tshuam loj thiab kev sib txhuam ntawm cov hlau, uas ua rau muaj kev cuam tshuam loj heev rau kev tsim khoom. Tom qab kev qhia txog cov phaj liner, cov discs sib tsoo thiab lwm yam khoom ua los ntawm alumina hnav-resistant ceramics, qhov xwm txheej tau hloov pauv ntau heev. Nws qhov Rockwell hardness siab txog HRA80-90, uas yog ntau zaus ntawm cov khoom siv hlau ib txwm muaj, thiab nws qhov kev tiv thaiv hnav zoo dua li cov khoom siv ib txwm muaj. Tom qab siv tiag tiag, nws tau raug txheeb xyuas tias lub neej ua haujlwm ntawm cov khoom siv siv alumina hnav-resistant ceramic Cheebtsam tau ntev dua 5 zaug, thiab tus lej ntawm lub sijhawm txij nkawm tau txo qis heev, txuag ntau tus neeg ua haujlwm thiab cov nqi khoom siv rau lub tuam txhab.
Tsis yog li ntawd xwb,Chemshun alumina hnav cov khoom siv ceramics uas tiv tauskuj muaj kev ruaj khov tshuaj zoo. Thaum ntsib cov khoom siv ore nyuaj thiab cov tshuaj lom neeg, lawv tuaj yeem tiv taus xeb thiab xyuas kom meej tias cov khoom siv ua haujlwm ib txwm muaj. Qhov no ua rau nws kuj ua lub luag haujlwm tseem ceeb hauv kev ua cov ntxhia, kev kho cov tailings thiab lwm yam kev sib txuas.
Nrog rau kev nce qib ntawm thev naus laus zis, kev siv alumina hnav-resistant ceramics hauv kev tsuas yuav dhau los ua ntau dua, thiab xav tias yuav dhau los ua lub zog tseem ceeb hauv kev txhawb nqa kev txhim kho zoo thiab ruaj khov ntawm kev lag luam tsuas.
