Qhov zoo ntawm cov khoom siv refractory ceramic hauv qhov cub tawg 3

Tsab ntawv xov xwm no peb yuav txuas ntxiv qhia txog qhov zoo ntawm cov refractory ceramic fiber.

Tsis tas yuav tsum tau ua kom qhov cub sov thiab ziab tom qab kev tsim kho
Yog tias lub cub tawg yog cov cib refractory thiab cov refractory castables, lub cub tawg yuav tsum tau ziab thiab preheated rau ib lub sijhawm raws li qhov xav tau. Thiab lub sijhawm ziab rau refractory castable yog ntev tshwj xeeb, feem ntau 4-7 hnub, uas txo qhov kev siv ntawm lub cub tawg. Yog tias lub cub tawg txais yuav tag nrho cov qauv fiber lining, thiab tsis txwv los ntawm lwm cov khoom siv hlau, qhov kub ntawm lub cub tawg tuaj yeem nce mus rau qhov kub ua haujlwm sai tom qab kev tsim kho. Qhov no tsis tsuas yog txhim kho qhov kev siv ntawm cov cub tawg kev lag luam, tab sis kuj txo qhov kev siv roj tsis yog tsim khoom.
Kev ua kom sov thermal tsawg heev
Cov fiber ceramic refractory yog cov fiber sib xyaw ua ke nrog txoj kab uas hla ntawm 3-5um. Muaj ntau qhov voids hauv lub masonry thiab cov thermal conductivity qis heev. Txawm li cas los xij, ntawm qhov kub sib txawv, qhov thermal conductivity qis tshaj plaws muaj qhov ceev zoo tshaj plaws, thiab qhov thermal conductivity qis tshaj plaws thiab qhov ceev sib xws nce nrog qhov nce ntawm qhov kub. Raws li kev paub ntawm kev siv lub cub tawg fiber ntau hauv xyoo tas los no, nws yog qhov zoo tshaj plaws thaum qhov ceev ntawm cov khoom siv tau tswj hwm ntawm 200 ~ 220 kg / m3.
Nws muaj kev ruaj khov tshuaj zoo thiab tiv taus cua yaig:
Tsuas yog phosphoric acid, hydrofluoric acid thiab alkali kub tuaj yeem corrodeCov khoom siv refractory ceramic fiberCov khoom siv refractory ceramic fiber ruaj khov rau lwm cov xov xwm corrosive.
