Dab tsi yog Txoj Kev Npaj Ntawm Magnesia Alumina Refractory Bricks? Yuav Siv Magnesium Mud Li Cas?

Dab tsi yog txoj kev npaj ntawm magnesia alumina refractory bricks? Yuav ua li cas sib tov magnesium av?

1. Txoj kev npaj ntawm magnesia-alumina refractory cib

Magnesia alumina refractory cibyog cov khoom siv refractory nrog magnesium oxide thiab alumina ua nws cov khoom tseem ceeb. Nws muaj hluav taws kub zoo heev thiab kub kub stability. Nws txoj kev npaj feem ntau suav nrog cov kauj ruam hauv qab no:
1. Cov khoom xyaw: Raws li kev ua tau zoo ntawm qhov yuav tsum tau muaj magnesia alumina refractory cib, xaiv cov khoom tsim nyog magnesium oxide thiab alumina raw cov ntaub ntawv, thiab ua cov khoom xyaw raws li ib qho kev faib ua feem.
2. Kev sib xyaw: Ua tib zoo sib xyaw cov magnesium oxide thiab aluminium oxide hauv cov khoom xyaw kom ntseeg tau tias txawm tias faib cov khoom siv raw.
3. Kev sib sau: Muab cov khoom sib xyaw ua ke rau hauv pwm thiab daim ntawvrefractory bricksnyob rau hauv qhov xav tau zoo los ntawm nias los yog extrusion.
4. Qhuav: Qhuav cov tsim refractory cib kom tshem tawm cov dej noo.
5. Kev tua hluav taws: Muab cov pob hluav taws qhuav refractory cib rau hauv lub qhov cub kub kub rau kev tua hluav taws los txhawb cov tshuaj lom neeg thiab kev hloov pauv ntawm cov khoom siv raw.
6. Txias: Cov cib refractory raug rho tawm haujlwm yog txias lawm los yog yuam kom tau qhov kev ua tau zoo.

2. Qhov piv ntawm magnesia av nkos

Magnesia av nkos yog ib qho tseem ceeb raw cov ntaub ntawv nyob rau hauv cov txheej txheem ntawm kev npaj ntawm magnesia alumina refractory bricks, thiab nws cov feem muaj ib tug tseem ceeb lub luag hauj lwm rau kev ua tau zoo ntawm refractory bricks. Feem ntau hais lus, qhov piv ntawm cov av nplaum magnesia yuav tsum xav txog cov hauv qab no:

1. Qhov piv ntawm magnesium oxide thiab alumina: Xaiv qhov tsim nyog piv ntawm magnesium oxide thiab alumina raws li kev ua tau zoo ntawm cov khoom siv hluav taws xob refractory. Feem ntau hais lus, magnesia av nkos nrog cov ntsiab lus magnesium oxide ntau dua muaj kev tiv thaiv hluav taws zoo dua thiab kub siab.
2. Tus nqi ntawm cov av nplaum los yog binder siv: Cov av nplaum los yog binder muaj ib qho tseem ceeb cuam tshuam rau lub plasticity thiab sintering kev ua tau zoo ntawm magnesia av nkos. Ib qho tsim nyog ntawm av nplaum los yog binder tuaj yeem txhim kho cov yas thiab sintering kev ua tau zoo ntawm magnesia av nkos, tab sis ntau av nplaum los yog binder yuav txo qhov kev ua tau zoo ntawm refractory cib.
3. Cov ntsiab lus noo noo: Cov dej noo nyob hauv cov av nplaum magnesia muaj qhov cuam tshuam tseem ceeb ntawm cov txheej txheem molding thiab firing. Qhov tsim nyog ntawm cov dej noo tuaj yeem txhim kho cov plasticity thiab fluidity ntawm cov av nplaum magnesia, tab sis cov av noo ntau dhau yuav ua rau muaj teeb meem hauv molding thiab txo qhov kev ua tau zoo ntawm refractory firebricks tom qab tua.
4. Tus nqi ntawm lwm yam additives: Raws li xav tau, cov nqi tsim nyog ntawm lwm cov khoom ntxiv, xws li hlau oxide, chromium oxide, thiab lwm yam, tuaj yeem muab ntxiv rau cov av nplaum magnesia los txhim kho kev ua haujlwm ntawm cov cib refractory.
