dawb fused alumina yog cov khoom siv zoo refractory uas nws lub cev muaj zog ua rau nws zoo tagnrho cov khoom siv kub. dawb fused alumina muaj qhov zoo ntawm kev ua haujlwm siab, siab hnav tsis kam, siab kub tsis kam, tshuaj lom neeg ruaj khov, siab melting kuj, thiab lwm yam, yog li nws yog dav siv hauv boilers, ceramics, iav, hlau, roj av, tshuaj chiv thiab lwm yam lag luam. .
Cov tshuaj muaj pes tsawg leeg ntawm dawb fused alumina feem ntau yog aluminaa (Al2O3), uas muaj cov siv lead ua zoo, siab zog, zoo thermal stability, thiab muaj peev xwm tiv taus kub thiab tshuaj yaig. Nws yog ib qho zoo tagnrho fireproof khoom. dawb fused alumina feem ntau yog ua los ntawm high-purity aluminaa, alumina thiab lwm yam additives los ntawm high-temperature calcination. Nws cov txheej txheem kev npaj yuav tsum muaj kev xav tau siab heev, thiab cov txheej txheem tsim khoom yuav tsum tau tswj nruj heev.
Lub ntsiab ntawm daim ntawv thov ntawm dawb fused alumina yog nyob rau hauv lub tshav pob ntawm refractory cov ntaub ntawv, vim hais tias ntawm nws zoo heev stability thiab corrosion kuj nyob rau hauv kub kub ib puag ncig. dawb fused alumina refractories tuaj yeem tiv taus kub hnav thiab tshuaj lom neeg yaig, yog li lawv feem ntau siv los ua cov cuab yeej kub xws li cov khoom siv hluav taws xob, lub tshuab hluav taws xob kub kub, cov thawv hlau molten, thiab khob abrasive log.
dawb fused alumina refractory khoom muaj lub zog txhua yam thiab hnav tsis kam, tsis yooj yim tawg, thiab tsis yooj yim rau eroded los ntawm tshav kub thiab tshuaj. Tsis tas li ntawd, dawb fused alumina muaj cov rwb thaiv tsev zoo, yog li dawb fused alumina feem ntau siv los thaiv cov khoom siv hluav taws xob thiab cov ntaub ntawv thermal rwb thaiv tsev nyob rau hauv qhov kub thiab txias. Tsis tas li ntawd, dawb fused alumina refractories kuj tseem siv rau hauv kev tsim cov alumina furnaces thiab fluidized txaj burner kav vim lawv cov tshuaj ruaj khov thiab muaj peev xwm tiv taus kev yaig ntawm cov roj kub kub.
Hauv kev xaus, dawb fused alumina refractory muaj qhov zoo ntawm qhov kub thiab txias, siab zog thiab siab tshuaj stability, thiab tau siv dav. Kev tshawb fawb thiab kev siv ntawm cov dawb fused alumina muaj kev loj hlob zoo, thiab nws txoj hauj lwm nyob rau hauv lub tshav pob ntawm high-temperature cov ntaub ntawv tau raug consolidated tsis tu ncua.
