Alkali resistant thaiv yog ib yam uas tsis muaj alumina cib, Al2O3 cov ntsiab lus yog 30-25%, cov khoom tseem ceeb ntawm alkali resistant blocks yog tsawg alumina refractory av nplaum, alkali resistant hluav taws thaiv yog ib yam ntawm silicaalumina series refractory khoom nrog zoo alkali yaig kuj. kev ua haujlwm hauv cement kiln system. alkali resistant refractory block muaj lub zog siab, zoo ntim ruaj khov, muaj peev xwm alkali yaig, thiab lwm yam. alkali resistant refractory thaiv yog siv rau cov cement kiln preheater thiab decomposing rauv.
Alkali resistant cib yog nyob rau ntawm qhov kub thiab txias yuav hnov mob nrog alkali hlau oxide generated siab viscosity ntawm cov kua theem, tsim ib txheej ntawm glaze yog hloov cov duab txheej, npog lub cib thaiv nto pores, tiv thaiv infiltration thiab yaig ntawm alkali. hlau molten khoom, muaj lub hom phiaj ntawm alkali yaig. alkali resistant thaiv yog hais txog qis alkali resistant cib refractory av nplaum ua cov khoom siv tseem ceeb, uas yog ua los ntawm txhuas hauv cov cement kiln system thiab muaj alkali corrosion kuj zoo thiab thermal conductivity tsawg.
Alkali resistant bricks yuav muab faib ua plaub hom: hom alkali resistant cib, siab zog alkali resistant firebrick, vault hom alkali resistant thaiv thiab thermal rwb thaiv tsev hom alkali resistant thaiv.
Feem ntau alkali resistant cib yog siv nyob rau hauv cement kiln preheater thiab decomposing rauv peb zaug.
Lub zog muaj zog alkali resistant firebrick feem ntau yog siv hauv cov cement kiln preheater, decomposed rauv, peb cov cua ducts, ntsug rising flue, cyclone cylinder.
Vault hom alkali resistant thaiv yog tsuas yog siv nyob rau hauv cement kiln preheater thiab decomposing rauv peb zaug.
Thermal rwb thaiv tsev hom alkali resistant thaiv muaj zoo alkali corrosion kuj thiab thermal conductivity tsawg, muaj tshav kub rwb thaiv tsev kev ua tau zoo ntawm silica alumina refractory khoom.
