Ceramic fiber module yog ib hom tshiab ntawm cov khoom siv refractory hauv ob sab phlu tsim los ua kom yooj yim thiab ua kom yooj yim rau kev tsim cov kiln thiab txhim kho kev ncaj ncees ntawm ob sab. Cov khoom yog xim dawb thiab tsis tu ncua ntawm qhov loj me. Nws tuaj yeem raug kho ncaj qha rau ntawm cov hlau phaj anchoring rau tes ntawm cov khoom siv hluav taws xob. .
Cov khoom siv tshuaj lom neeg ntawm ceramic fiber module yog qhov ruaj khov rau tag nrho, thiab nws muaj kev tiv thaiv zoo rau cov kua qaub thiab alkali yaig, tab sis cov ceramic fiber module yuav tsum tsis txhob siv rau hauv qhov cub cua ntawm cov khoom hauv qab no.
01 Fluorine
Fluorine yog cov corrosive tshaj plaws rau ceramic fibers, thiab nws reacts nrog tag nrho cov ntaub ntawv aluminosilicate, nrog rau mullite fibers.
02 Vanadium thiab lwm yam hlau hnyav
Vanadium thiab lwm yam hlau hnyav hauv cov roj tsis zoo yuav tsim V2O5 thaum nws hlawv. Nws melts mus rau hauv cov kua ntawm li 690 degrees, adsorbs nyob rau hauv lub pores ntawm fiber, thiab tsim ib lub plhaub tawv ntawm lub fiber hauv ob sab phlu, uas corrodes txheej los ntawm txheej tom qab ntog tawm.
03 Sulfur thiab sulfuric acid
Sulfuric acid, thaum tsis muaj kev cuam tshuam nrog ceramic fibers, yog corrosive heev rau hlau thauj tog rau nkoj, thiab nyob rau hauv tej rooj plaub txawm "dissolve" anchors thiab furnace shells.
04 Alkali hlau
Ntev siv nyob rau hauv ib puag ncig alkaline tuaj yeem ua rau shrinkage thiab puas rau cov fibers hauv ob sab phlu, thiab cov txheej saum npoo yuav txuas ntxiv corrode txheej hauv qab tom qab tev tawm.
05 sulfuric acid
Kev sim tau pom tias thaum siv nyob rau hauv ib puag ncig siab dua 540 ° C rau lub sijhawm ntev, cov fiber ntau yuav txo qis.
