Yuav ua li cas yog qhov tseeb anti-alkali txoj kev kho rau refractory bricks?
Yuav ua li cas yog qhov tseeb anti-alkali txoj kev kho rau refractory cib?
1. Direct contact melt erosion method. Nyob rau hauv qhov kub-kub sealing tej yam kev mob, cov hlau molten yog nyob rau hauv ncaj qha kev sib cuag nrog lub xeem thaiv rau corrosion tshuaj ntsuam xyuas cov kev hloov nyob rau hauv ntau yam khoom ua ntej thiab tom qab cov qauv yog corroded. Ob txoj kev siv qhov kev hloov me me los qhia qhov alkali tsis kam ntawm siab alumina refractory cib. Qhov zoo dua.
2. Kev sib xyaw ua kom yaig. Cov coke hais yog tov nrog anhydrous K2CO3, qhov kev sim thaiv yog faus rau hauv nws, thiab qhov kev sim thaiv yog corroded nyob rau hauv high-temperature sealing tej yam kev mob los txiav txim qhov luaj li cas hloov los yog lub zog txo tus nqi ntawm lub xeem block ua ntej thiab tom qab nws eroded.
3. Lub alkali tsis kam ntawm refractory bricks yog lub peev xwm ntawm siab alumina refractory cib los tiv thaiv alkali corrosion ntawm qhov kub thiab txias. Nyob rau hauv cov txheej txheem blasting rauv smelting, lub refractory cib yuav corroded los ntawm alkali. Piv txwv li, yog tias cov khoom siv raw tau ntxiv rau cov khoom noj uas muaj alkali, qhov kev yaig ntawm cov alkali-muaj cov ntxhia hauv cov ntaub ntawm aluminium-silicon thiab carbon refractory cib cuam tshuam los ntawm alkali concentration, kub thiab dej vapor, uas cuam tshuam nrog kev pabcuam. lub neej ntawm cov blast furnace hauv ob sab phlu thiab txhim kho qhov tsis kam ntawm refractory bricks. Alkali kev ua tau zoo txuas ntxiv lub neej kev pab cuam ntawm lub qhov cub tawg.
