Qhov zoo ntawm Ceramic Fiber Materials Over Traditional Refractory Materials (Part 1)

May 26, 2022

Cov khoom siv fiber ntau ceramic muaj ntau yam zoo, xws li lub teeb yuag, kub tsis kam, zoo thermal rwb thaiv tsev nyhuv, thiab lwm yam. Piv nrog rau cov khoom siv refractory tsoos, cov khoom siv fiber ntau muaj cov hauv qab no zoo:

1. Lub teeb yuag (txo lub load ntawm lub kiln thiab ncua lub neej ntawm lub cub tawg lub cev) ceramic fiber yog fiber ntau refractory khoom. Feem ntau siv refractory fiber ntau daim pam muaj qhov ceev ntawm 96-128Kg/m3, thiab daim pam fiber ntau yog folded. Cov kev ntig ntom ntom ntawm refractory fiber ntau cov modules yog nruab nrab ntawm {1}}}}}}}}}}}}}}}}} / 20 ntawm hnyav refractory khoom. Nws tuaj yeem pom tias cov khoom siv fiber ntau refractory tuaj yeem ua kom tiav lub teeb-yuag thiab ua haujlwm siab cua sov rauv, txo qhov load ntawm lub kiln, thiab txuas lub neej ntawm lub cub tawg.

2. Tsawg cua sov muaj peev xwm (tsawg tshav kub nqus, cua sov ceev): Lub peev xwm ntawm cov khoom siv hauv ob sab phlu feem ntau yog proportional rau qhov hnyav ntawm lub qhov cub hauv ob sab phlu. Tsawg tshav kub muaj peev xwm txhais tau hais tias lub cub tawg absorbs tsawg tshav kub thaum lub sij hawm reciprocating ua hauj lwm, thiab cov cua kub ceev yog ceev ua ke. Lub peev xwm kub ntawm ceramic fiber tsuas yog 1/10 ntawm lub teeb-hnyav tshav kub-resistant fabrics thiab lub teeb yuag refractory bricks, uas zoo heev txo lub zog noj nyob rau hauv lub lag luam thiab kev tswj ntawm lub cub tawg kub. .

3. Tsawg thermal conductivity (tsawg tshav kub): cov thermal conductivity ntawm ceramic fiber ntau yog tsawg dua 0.06W/mk ntawm ib tug zoo kub ntawm 200 degree , thiab tsawg tshaj li 0.10W/mk ntawm qhov nruab nrab kub ntawm 400 degree, uas yog kwv yees li 1 feem pua ​​​​ntawm cov khoom siv hluav taws kub-resistant amorphous. / 8, uas yog hais txog 1/10 ntawm lub teeb ci ci, thiab thermal conductivity ntawm ceramic fiber ntau piv nrog cov khoom hnyav refractory yog negligible. Yog li ntawd, thermal rwb thaiv tsev nyhuv ntawm cov khoom siv fiber ntau refractory yog qhov tseem ceeb heev.

4. Kev tsim kho yooj yim (tsis tas yuav tawm hauv cov pob qij txha loj): cov neeg ua haujlwm tsim kho tuaj yeem nqa lawv cov haujlwm tom qab kev cob qhia yooj yim, thiab kev tsim kho cov ntsiab lus muaj kev cuam tshuam me ntsis rau cov thermal rwb thaiv tsev ntawm lub qhov cub hauv ob sab phlu.
