Silica Fume rau Refractory Applications

Silica fume yog ib yam khoom tseem ceeb rau cov ntawv thov refractory vim nws cov ntsiab lus silica siab, tsis tshua muaj porosity, thiab siab tshwj xeeb thaj chaw. Nws yog siv los ua cov khoom muab tub lim hauv cov khoom siv hluav taws xob refractory castables, phom sib tov, thiab lwm yam khoom siv refractory los txhim kho lawv cov khoom thiab kev ua haujlwm.

Ib qho txiaj ntsig tseem ceeb ntawm kev siv silica fume hauv cov ntawv thov refractory yog nws lub peev xwm los txhim kho lub zog thiab kav ntev ntawm cov khoom siv refractory. Silica fume hais yog heev reactive thiab muaj peev xwm sib txuas nrog lwm cov ntaub ntawv nyob rau hauv lub refractory mix, ua rau ib tug denser thiab ntau compact qauv. Qhov no tuaj yeem ua rau muaj zog tiv thaiv thermal shock thiab mechanical stress.

Ntxiv nrog rau nws cov khoom txhawb zog, silica fume kuj pab txo cov permeability ntawm cov khoom refractory, ua rau lawv tiv taus tshuaj tua kab mob thiab yaig. Nws qhov tshwj xeeb saum npoo av tso cai rau nws nqus thiab khi nrog lwm cov ntaub ntawv, uas tuaj yeem pab txhim kho tag nrho cov khoom ntawm cov khoom siv refractory.
