Refractory qib dawb aluminium oxide yog cov khoom npaj los ntawm high-purity alumina. Nws cov tshuaj lom neeg muaj pes tsawg leeg thiab lub cev muaj zog ua rau nws zoo heev ntawm qhov kub thiab txias ib puag ncig. Piv nrog rau cov khoom siv refractory tsoos, cov khoom siv tshiab no muaj cov txiaj ntsig zoo hauv qab no:
High Temperature Stability: Refractory qib dawb aluminium oxide muaj kev ruaj ntseg zoo heev ntawm qhov kub thiab txias tuaj yeem tiv taus huab cua kub thiab thermal shock.
Corrosion tsis kam: Cov khoom muaj kev tiv thaiv siab rau acid thiab alkali corrosion, thiab tuaj yeem siv rau hauv qhov chaw hnyav rau lub sijhawm ntev yam tsis muaj kev puas tsuaj.
Cov thermal conductivity zoo heev: Refractory qib dawb aluminium oxide muaj cov thermal conductivity zoo, tuaj yeem ua cua sov sai, thiab txhim kho thermal efficiency thiab siv zog.
Lub teeb yuag thiab siab zog: Txawm hais tias nws lub teeb yuag, cov khoom siv tshiab no muaj lub zog tshwj xeeb thiab ruaj khov, ua rau nws zoo tagnrho rau kev tsim cov khoom siv hluav taws xob.
Plasticity thiab processability: Refractory qib dawb aluminium oxide tuaj yeem tsim nyob rau hauv cov duab nyuaj los ntawm ntau txoj kev ua, xws li nias, txhaj tshuaj molding thiab sib sau, muab kev ywj pheej tsim ntau dua.
Vim cov khoom zoo kawg li no, qib refractory dawb aluminium oxide yog siv dav hauv ntau qhov kev lag luam. Nws yog dav siv nyob rau hauv high-temperature furnaces, foundry kev lag luam, iav kev lag luam, hlau thiab steel smelting, tshuaj lom neeg kev lag luam thiab lwm yam teb, ua tau raws li cov kev ua tau zoo ntawm cov kev lag luam sib txawv rau cov ntaub ntawv refractory.
Nrog rau kev saib xyuas ntau ntxiv rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov, qib refractory dawb aluminium oxide kuj ua raws li cov qauv kev tiv thaiv ib puag ncig ntsuab thiab maj mam dhau los ua thawj qhov kev xaiv los hloov cov khoom siv refractory.
