Hauv cov teb ntawm kev tsuas, cement, kev tsim hluav taws xob, thiab kev tsim kho tshuab hnyav, kev hnav thiab rhuav tshem ntawm cov khoom siv ua rau kev ua haujlwm tsis zoo thiab kev them nqi kho ntxiv. Raws li kev daws teeb meem tiv thaiv kev hnav zoo, lub alumina ceramic dimple liner uas tiv taus kev hnav ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua los ntawm nws cov qauv tsim sib xyaw. Feem ntau tsim los ntawm alumina ntshiab (Al₂O₃) nrog cov ntsiab lus ntawm ≥92%, cov liners no raug sintered siv cov txheej txheem kub siab qhuav-nias, ua rau muaj qhov ceev ceev thiab cov qauv sib xws.
Lub thev naus laus zis tseem ceeb ntawm cov khoom no yog nyob rau hauv nws qhov "dimple" lossis "bump" geometric nto tsim thiab cov khoom siv lub cev txhim khu kev qha. Lub qauv dimple zoo ua rau lub ntsiab lus sib cuag siab ntawm cov khoom siv thiab lub liner nto, uas pab rhuav cov zaj duab xis huab cua ntawm cov khoom siv thiab phab ntsa hauv cov txheej txheem xa khoom lossis chute, yog li txhim kho cov khoom ntws thiab tiv thaiv kev nplaum. Hauv cov ntaub ntawv kev ua tau zoo, 92% alumina ceramic feem ntau ua tiav Rockwell hardness (HRA) ntawm ntau dua 80, qhov ceev ntawm ≥3.6 g / cm³, thiab nws qhov kev tiv thaiv hnav yog 15 zaug lossis siab dua li ntawm cov hlau manganese siab ib txwm muaj. Ntxiv mus, cov ntaub ntawv ceramic siab-alumina muab kev tiv thaiv kub siab zoo heev thiab kev tiv thaiv corrosion, ua rau lawv hloov kho rau cov xwm txheej ua haujlwm hauv kev lag luam nyuaj.
Hauv cov ntawv thov tshwj xeeb hauv cov khoom siv engineering, cov dimple liners siv dav rau pulley lagging hauv cov siv conveyor, chutes, hoppers, thiab mill linings. Cov txheej txheem teeb tsa cuam tshuam ncaj qha rau qhov kev tiv thaiv; cov kauj ruam tseem ceeb suav nrog: xuab zeb rau ntawm qhov chaw (ua tiav ISO Sa2.5 kev huv), sib npaug zos siv ob-component polymer nplaum (tswj thickness rau 1-2 hli), thiab staggered bonding ntawm cov liners kom ntseeg tau tias muaj kev faib tawm kev ntxhov siab. Vim lawv sab nraub qaum feem ntau tsim nrog grooves lossis dovetail slots, dimple liners tsim lub xauv tshuab nrog cov nplaum, muab kev tiv thaiv zoo dua rau kev sib cais hauv qab kev cuam tshuam ntawm cov khoom siv ceev ceev.
Hauv kev xaus, kev siv ntawmCov ntaub thaiv qhov rai alumina ceramic uas tiv taus hnavyog ib qho kev xaiv pheej yig thiab txhim khu kev qha rau kev ua tiav kev tiv thaiv mus sij hawm ntev ntawm cov khoom siv engineering. Nws tsis tsuas yog tiv taus cov khoom hnav los ntawm kev nyuaj siab tab sis kuj txhim kho kev ua haujlwm los ntawm kev ua kom zoo dua ntawm qhov chaw geometry. Rau cov lag luam nrhiav kev ruaj khov ua haujlwm thiab txo cov nqi khiav lag luam tag nrho, kev xaiv cov khoom los ntawm cov chaw tsim khoom muaj npe nrov uas ua tau raws li cov lus qhia tshwj xeeb (xws li Al₂O₃ cov ntsiab lus, qhov nyuaj, thiab kev nqus dej) thiab ua raws li cov txheej txheem teeb tsa tus qauv yog qhov tseem ceeb rau kev ua kom muaj kev tiv thaiv kev hnav zoo.
