Ib pawg ntawm cov ntawv thov ntawm cov khoom siv alumina ceramics uas tiv taus hnav

Qhov kev tiv thaiv kev hnav ntawm alumina ceramics yog los ntawm lawv cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb: Mohs hardness ntawm alumina ceramics yog 9, thib ob tsuas yog pob zeb diamond. Microscopically, cov qauv siv lead ua ke uas muaj cov ionic bonds muaj zog tuaj yeem tiv taus kev nkag mus ntawm cov khoom hnav. Cov kev tshawb fawb qhia tau tias nws qhov kev tiv thaiv kev hnav tuaj yeem ncav cuag 266 npaug ntawm cov hlau manganese thiab 171.5 npaug ntawm cov hlau cam khwb cia siab chromium. Ntxiv mus, alumina ceramics muaj kev ruaj ntseg tshuaj lom neeg thiab thermal. Lawv tuaj yeem tswj tau qhov kev ua haujlwm zoo hauv cov kua qaub, alkaline thiab qhov kub thiab txias thiab tuaj yeem siv rau hauv cov xwm txheej ua haujlwm hnyav.

Cov xwm txheej ntawm daim ntawv thovalumina ceramics uas tsis yooj yim puas:
1. Cov khoom siv kho tshuab uas tsis yooj yim puas:cov tshuab xa khoom (xws li cov ntsia hlau conveyors, pneumatic conveying pipelines, thiab lwm yam), twj tso kua mis thiab lub valve foob, mixer blades, bearings, ceramic txiav cov cuab yeej, thiab lwm yam. Nws tuaj yeem hloov cov khoom siv hlau ib txwm muaj thiab txo cov khoom siv downtime rau kev txij nkawm los ntawm kev hnav thiab tsim kua muag.
2. Kev lag luam mining thiab metallurgical:Nws yog siv rau hauv cov crushers, cov khoom siv ua cov ntxhia (xws li cov ntaub sab hauv ntawm cov cua daj cua dub), cov khoom sib tsoo rau cov pob zeb, cov ntaub sab hauv ntawm cov qhov cub kub siab, thiab lwm yam. Tiv taus qhov cuam tshuam thiab kev hnav ntawm cov ores thiab slag, thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom siv.
3. Kev thauj mus los ntawm roj teeb lithium:Cov kav dej alumina ceramic yog siv rau hauv cov kav dej thauj roj teeb lithium, uas tsis yog tsuas yog ua kom cov kav dej ruaj khov xwb tab sis kuj tiv thaiv kev ua qias tuaj thiab txuag tus nqi ntawm kev hloov cov kav dej.
4. Kev lag luam hluav taws xob thiab semiconductor:Cov laug cam sib xyaw ua ke, cov ntaub ntawv ntim khoom siv hluav taws xob, cov khoom siv rwb thaiv tsev siab, cov khoom siv tiv taus hnav hauv cov khoom siv ua wafer (xws li caj npab robotic, cov khoom siv), cov chav tshuaj tiv thaiv corrosion.
5. Kev lag luam tshuaj lom neeg thiab roj av:Cov ntaub sab hauv ntawm cov hlab dej tshuaj, cov twj tso kua tshuaj thiab cov qhov dej, cov kav dej, cov khoom siv centrifuge, cov nplhaib uas tiv taus kev hnav rau cov khoom siv drilling. Cov bushings twj tso kua av nkos thiab cov ntaub sab hauv ntawm cov kav dej roj.

Qhov kev tiv taus siab ntawm alumina ceramics yog nws qhov kev sib tw tseem ceeb hauv kev lag luam. Thiab los ntawm kev sib xyaw cov khoom siv, kev tsim kho tshiab thiab kev nthuav dav ntawm daim ntawv thov, nws lub peev xwm tseem raug tso tawm tas li. Yav tom ntej, kev lag luam yuav tsum txhim kho qhov tawv ntawm cov ntaub ntawv thiab txo cov nqi thaum tsom mus rau qhov kev thov ntawm kev ua lag luam siab, txhawb kev hloov pauv ntawm "ntau" mus rau "zoo", thiab muab cov kev daws teeb meem zoo dua rau cov teb tshiab xws li kev tsim khoom ntse thiab lub zog ntsuab.
