Cov ntaub ntawv rwb thaiv tsev refractory fiber siv rau hauv kev tsim kho cub tawg 3

Tsab ntawv xov xwm no peb yuav txuas ntxiv qhia txog cov khoom siv rwb thaiv tsev refractory fiber uas siv rau hauv kev tsim lub cub tawg.

1) Cov fiber refractory
Refractory fiber, tseem hu ua ceramic fiber, yog ib hom khoom siv inorganic uas tsis yog hlau uas tib neeg ua, uas yog iav lossis crystalline theem binary compound uas muaj Al2O3 thiab SiO2 ua cov khoom tseem ceeb. Ua cov khoom siv rwb thaiv tsev uas tsis hnyav, nws tuaj yeem txuag hluav taws xob los ntawm 15-30% thaum siv rau hauv cov cub tawg. Refractory fiber muaj cov yam ntxwv zoo hauv qab no:
(1) Kev ua haujlwm kub siab. Qhov kub ua haujlwm ntawm cov khoom siv refractory fiber ntau yog 1200 ° C, thiab qhov kub ua haujlwm ntawm cov khoom siv refractory tshwj xeeb xws li alumina fiber thiab mullite yog siab txog 1600-2000 ° C, thaum qhov kub refractory ntawm cov khoom siv fiber dav dav xws li asbestos thiab pob zeb wool tsuas yog li 650 ° C.
(2) Kev rwb thaiv cua sov. Lub thermal conductivity ntawm refractory fiber yog qis heev ntawm qhov kub siab, thiab lub thermal conductivity ntawm cov txhuas silicate refractory fiber ntawm 1000 ° C yog 1/3 ntawm cov cib av nplaum sib dua, thiab nws lub peev xwm cua sov yog me me, kev rwb thaiv cua sov zoo heev. Lub thickness ntawm lub cub tawg tsim tuaj yeem txo qis li ib nrab piv rau kev siv cov cib refractory sib dua.
