Ua ntej, xaiv cov ntaub ntawv plhaub xws li zirconium xuab zeb / quartz hmoov zoo yuav tsum ua tau raws li cov kev cai, tshwj xeeb tshaj yog cov oxides nyob rau hauv txheej txheej ntawm cov ntaub ntawv refractory yuav tsum tau poob rau hauv cov txheej txheem, tshwj xeeb tshaj yog cov ntsiab lus ntawm hlau oxides thiab lwm yam oxides tsis tau tshaj, zus tau tej cov siab Fe2O3 cov ntsiab lus yuav aggravate pitting.
Thib ob, txhawm rau kuaj cov khoom siv raw, tsim nyog rau hauv cov nroj tsuag, warehouse. Cov khoom lag luam ntawm cov khoom siv raw mus rau ib txwm rov- kev tshuaj xyuas, cov khoom siv tsis zoo tuaj yeem siv tsis tau.
