Kev taw qhia thiab kev siv lub zog siab alkali resistant cib
Lub siab muaj zog alkali resistant cib muaj corrosion kuj zoo rau metallurgical slag, cement clinker, iav kiln cov khoom xyaw thiab tshauv. Kev cuam tshuam ntawm cov xov xwm kub sib txawv ntawm alkaline cib sib txawv. Nyob rau hauv ib qho chaw muaj zog alkaline, xws li cement kiln firing tsam, qhov kev txiav txim ntawm cov cement clinker yaig kuj yog: magnesia dolomite cib> magnesia chrome cib> magnesia spinel cib.
Siab zog alkali resistant cib yog ib hom refractory cib ua los ntawm kev ntxiv silica, coke lub pov haum thiab tsim nyog additives los txhim kho lub compressive zog raws li zoo tib yam alkali resistant cib. Qhov hnyav ntawm high-strength firebrick yog hais txog 5 kilograms. Nyob rau hauv tus txheej txheem ntawm kev siv, high-strength alkali-resistant cib reacts nrog alkaline oxide los ua ib tug high-viscosity iav theem, uas npog lub nto ntawm lub cib los thaiv lub nto porosity, tiv thaiv infiltration ntawm alkaline slag, thiab ua tiav lub hom phiaj. ntawm alkali tsis kam thiab corrosion kuj.
