Cov khoom siv tshuaj lom neeg ntawm ceramic fiber module yog qhov ruaj khov rau tag nrho, thiab muaj kev tiv thaiv zoo rau cov kua qaub thiab alkali corrosion. Txawm li cas los xij, cov khoom siv fiber ntau ceramic tsis haum rau kev siv hauv qhov cub cua ntawm cov khoom hauv qab no.
1 Fluorine thiab fluoride
Fluorine yog corrosive tshaj plaws rau ceramic fibers, thiab nws reacts nrog tag nrho cov txhuas silicate cov ntaub ntawv, nrog rau mullite fibers.
2 Vanadium thiab lwm yam hlau hnyav
V2O5 yog tsim thaum vanadium thiab lwm yam hlau hnyav hauv cov roj tsis zoo. Nws yaj mus rau hauv cov kua ntawm li 690 degrees, adsorbs ntawm lub pores ntawm fiber ntau, thiab tsim ib lub plhaub tawv ntawm cov ntaub fiber ntau, uas yuav corrode txheej los ntawm txheej tom qab ntog tawm.
3 sulfur thiab sulfuric acid
Txawm hais tias sulfuric acid tsis hnov mob nrog ceramics fibers, nws corrodes hlau anchors tiag. Qee zaum, nws txawm" dissolves" cov anchors thiab furnace plhaub.
4 alkali hlau
Daim ntawv thov mus sij hawm ntev nyob rau hauv ib puag ncig alkaline yuav ua rau shrinkage thiab kev puas tsuaj ntawm cov fiber ntau hauv ob sab phlu, thiab yuav txuas ntxiv corrode hauv qab txheej tom qab txheej txheej ntog.
5 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.
