Daim ntawv thov ntawm Aluminium Dawb Castable

Cov ntaub ntawv tseem ceeb raug xaiv rau aluminium dawb castables yog: qib super bauxite, xim av corundum, - Al2O3 micropowder, silica micropowder, ntshiab calcium aluminate cement, admixture. Ntawm lawv, ntxiv cov ntshiab calcium aluminate cement yog 6 feem pua, uas txo cov sij hawm demoulding thiab txhim kho lub zog demoulding thiab chav tsev kub. - Al2O3 micropowder muaj kev ua haujlwm siab thiab ua haujlwm nrog SiO2 los ua mullite. Nws ua haujlwm ua ke nrog cov ntshiab calcium aluminate cement los txhim kho qhov siab - kub lub zog thiab txo qhov porosity. Tus admixture reacts nrog infiltrated molten aluminium los ua cov khoom siv ruaj khov, uas tau cuam tshuam zoo ntxiv ntawm kev tawm dag zog ntawm molution ntawm molaken aluminium thiab plays ib qho kev tiv thaiv tsis sib xws. Yog li ntawd, cov khoom siv tau zoo heev aluminium dej wettability thiab zoo corrosion kuj. Lub non-stick aluminium castable tau siv nyob rau hauv ib qho loj txhuas cog rau 300 tons. Nws tau siv rau masonry rau 2 xyoos, thiab cov nyhuv siv tau zoo heev.
