Qhov teeb meem no peb yuav qhia ntxiv txog qhov zoo ntawm refractory ceramic fiber.
Tsis xav tau qhov cub preheating thiab ziab tom qab kev tsim kho
Yog hais tias lub cub tawg yog refractory bricks thiab refractory castables, lub cub tawg yuav tsum tau qhuav thiab preheated rau ib lub sij hawm raws li ib tug yuav tsum tau. Thiab lub sij hawm ziab rau refractory castable yog ntev heev, feem ntau 4-7 hnub, uas txo qhov kev siv ntawm lub cub tawg. Yog hais tias lub cub tawg tau txais tag nrho cov fiber ntau hauv ob sab phlu, thiab tsis txwv los ntawm lwm yam hlau Cheebtsam, qhov kub thiab txias ntawm lub cub tawg yuav tsum ceev nrooj nce mus rau qhov kub thiab txias tom qab kev tsim kho. Qhov no tsis yog tsuas yog txhim kho kev siv cov khoom siv hluav taws xob, tab sis kuj txo qis kev siv roj tsis siv neeg.
Tsawg heev thermal conductivity
Refractory ceramic fiber yog fiber ntau ua ke nrog lub cheeb ntawm 3-5um. Muaj ntau voids nyob rau hauv lub masonry thiab thermal conductivity yog tsawg heev. Txawm li cas los xij, ntawm qhov sib txawv ntawm qhov kub thiab txias, qhov qis tshaj thermal conductivity muaj qhov sib xws ntawm qhov pom kev zoo, thiab qhov qis tshaj thermal conductivity thiab sib xws bulk ceev nce nrog qhov nce ntawm qhov kub thiab txias. Raws li kev paub dhau los ntawm kev siv tag nrho cov qauv fiber ntau tawg rau hauv lub xyoo tsis ntev los no, nws yog qhov zoo tshaj plaws thaum cov khoom ntom ntom ntawm 200 ~ 220 kg / m3.
Nws muaj tshuaj lom neeg ruaj khov thiab ua haujlwm rau huab cua yaig:
Tsuas yog phosphoric acid, hydrofluoric acid thiab kub alkali tuaj yeem corroderefractory ceramic fiber ntau. Refractory ceramic fiber yog ruaj khov rau lwm cov xov xwm corrosive.
