Tus hnav tus nqi ntawmalumina ceramic linerncaj qha txiav txim siab ncua kev txij nkawm thiab cov nqi khiav haujlwm. Los ntawm kev txheeb xyuas qhov tseem ceeb ntawm kev hnav khaub ncaws thiab ntsuas qhov sib txawv tseem ceeb xws li kev nrawm nrawm, particle hardness thiab kev cuam tshuam lub kaum ntse ntse, kev tsim vaj tsev - qib kev pab cuam lub neej kwv yees tuaj yeem ua yam tsis muaj kev ntsuas nyuaj.Cov hauv qab no yuav tau tham los ntawm peb yam: mechanism, tsis, thiab xaiv cov khoom siv.
Paub meej tias qhov tseem ceeb hnav mechanism
Alumina liners feem ntau dais zawv zawg abrasion thiab yaig hnav. Thaum cov khoom swb nyob rau saum npoo ntawm cov kaum sab xis, cov khoom tawv tsis tu ncua txiav cov ceramic matrix, thiab hnav qhov tob yog proportional rau zawv zawg qhov deb. Thaum cov khoom siv ntsug lossis ze li ntawm qhov cuam tshuam, qhov kev sib cuag hauv zos muaj kev ntxhov siab tshaj qhov tseem ceeb ntawm cov ceramic, ua rau microcrack propagation thiab thaum kawg ua rau nplej tev. Kev txheeb xyuas qhov tseem ceeb ntawm cov txheej txheem raws li kev thauj mus los thiab txoj hauv kev ntws yog thawj kauj ruam hauv kev kwv yees lub neej.
Cov kev hloov pauv tseem ceeb rau kev ntsuas tus nqi hnav
Three core parameters tswj tus nqi hnav. Thawj yog particle hardness: thaum Mohs hardness ntawm cov khoom conveyed qis dua 9, ceramic poob yog tsawg; lub xub ntiag ntawm cov impurities nyuaj ua rau tsis muaj -linear nce. Qhov thib ob yog qhov nrawm nrawm- cov ntaub ntawv hauv teb qhia tau hais tias cov erosive hnav roughly nplai nrog kev tshaj tawm mus rau lub zog ntawm 2.5, txhais tau tias ob npaug ntawm qhov nrawm nce qhov hnav ntawm li 5.7 npaug. Qhov thib peb yog qhov cuam tshuam lub kaum sab xis: nkig ceramics hnav sai tshaj plaws nyob rau hauv siab - lub kaum ntse ntse tab sis degrade qeeb ntawm cov kaum sab xis. Kev sau cov lej ua haujlwm no ua rau txhim kho kev kwv yees kev ntseeg tau.
Tus txheeb ze coj tus nqi txoj kev yog feem ntau siv nyob rau hauv industrial chaw. Introduce a purity correction factor based on the measured loss of 92% alumina lining under specific operating conditions. 95% alumina, due to its higher sintering density and fewer glass phases, typically has a volume wear rate 15% to 30% lower than 92% under the same impact conditions. Los ntawm kev sib txuas cov phab ntsa tuab ntawm cov txheej txheem tsim nrog qhov tsawg kawg nkaus tso cai tuab, lub voj voog kev nyab xeeb tuaj yeem suav tau, tso cai rau kev sib piv ncaj qha ntawm tag nrho cov nqi ntawm cov nqi sib txawv thaum xaiv, tsis txhob cia siab rau cov nqi tsev xwb.
