Silica Fume Refractory

Silica fume, tseem hu ua microsilica, yog cov khoom siv los ntawm kev tsim cov hlau silicon thiab ferrosilicon alloys. Nws yog cov hmoov zoo heev nrog qhov ntau thiab tsawg feem ntau nyob rau hauv thaj tsam ntawm 0.1 txog 1 micron. Silica fume yog reactive heev vim nws qhov me me me me thiab qhov chaw siab, thiab nws feem ntau yog siv los ua cov khoom siv pozzolanic hauv pob zeb los txhim kho nws lub zog thiab kav ntev.

Hauv daim ntawv thov refractory, silica fume feem ntau ntxiv rau castables, gunning mixes, thiab lwm yam khoom refractory los txhim kho lawv cov khoom. Silica fume tuaj yeem txhim kho lub zog, ua haujlwm tsis zoo, thiab thermal poob siab tsis kam ntawm cov ntaub ntawv refractory. Nws tuaj yeem txo qhov porosity ntawm refractories, uas tuaj yeem txhim kho lawv cov kev tiv thaiv corrosion thiab yaig.

Silica fume tuaj yeem siv rau hauv ntau yam khoom siv refractory, suav nrog high-alumina thiab mullite-based castables, phom sib tov, thiab cov cement castables tsawg. Nws yog feem ntau siv ua ke nrog lwm cov khoom siv ntxiv, xws li alumina, zirconia, thiab silicon carbide, los kho cov khoom ntawm cov refractory rau cov ntawv thov tshwj xeeb.
