Lub anomalous expansion tshem tawm ntawmcalcined xim av aluminium oxide
Lub anomalous expansion ntawm lub abrasive yuav ua rau reticular kab nrib pleb tshwm nyob rau hauv cov txheej txheem ntawm ua xim av aluminium oxide sib tsoo log, thiab ua rau ntau yam khoom pov tseg yog tsim. Txawm li cas los xij, calcination yog ib txoj hauv kev zoo los tshem tawm anomalous expansion ntawm abrasives.
Lub toughness thiab sib tsoo kev ua tau zoo txhim kho ntawm calcined xim av aluminium oxide
Lub zog compressive ntawm cov abrasive tuaj yeem txhim kho thaum lub sij hawm calcination, thiab kev ntxhov siab sab hauv los ntawm cov txheej txheem granulation kuj tuaj yeem tsim. Cov cuab yeej abrasive ua los ntawm nws tsis yog tsuas yog ruaj tab sis kuj ntse, yog li kev sib tsoo kev ua tau zoo tuaj yeem txhim kho.
Kev txhim kho hydrophilicity ntawm calcined xim av aluminium oxide
Tus naj npawb ntawm capillary nyob rau saum npoo ntawm abrasive yog nce, vim impurities xws li volatiles yog cleared thiab tsawg melting point tshuaj raug hlawv tawm. Yog li ntawd, lub hydrophilicity ntawm cov khoom yog txhim kho.
Cov cuab yeej abrasive txhim kho lub zog ntawm calcined xim av aluminium oxide
Volatiles thiab lwm yam impurities raug tshem tawm tom qab lub abrasive ua tiav los ntawm calcination, uas txhim kho nws cov purity thiab huv. Yog li ntawd, lub zog khi ntawm cov abrasive thiab cov binder yog nce, uas txhim kho lub zog ntawm cov cuab yeej abrasive.
Cov tsos thiab txiav muaj peev xwm txhim kho ntawm calcined xim av aluminium oxide
Tom qab calcination, cov khoom sib nqus tau yooj yim raug tshem tawm, uas txo nws cov ntsiab lus thiab txhim kho cov tsos ntawm cov cuab yeej abrasive. Yog li, cov khoom no muab kev txiav zoo dua thiab kev ua haujlwm tag nrho.
