Topower Rwb thaiv tsev Ceramic Fiber Blanket Kev muag khoom, Cov neeg siv khoom hauv tebchaws United Arab Emirates Ordered 25tons
Zoo thermal aluminium silicateceramic fiber daim pamdav siv rau kev lag luam furnace rwb thaiv tsev refractory
Qhov ntim ntom ntawm ceramic fiber yog hais txog qhov sib piv ntawm qhov hnyav ntawm cov khoom siv fiber ntau rau tag nrho cov khoom. Qhov loj ntawm lub ntim ntom yog qhov ntsuas uas txiav txim siab seb puas xaiv cov cub hluav taws yog tsim nyog. Nws yog ib qho tseem ceeb uas cuam tshuam rau thermal conductivity:
Lub thermal condicity cov khoom siv ceramic fiber ntau zuj zus mus ntxiv nrog qhov nce zuj zus, tab sis qhov kev txo qis dua qhov ntau, cov thermal conductivity tsis tsawg, tab sis nyhav ntxiv. Muaj qhov tsawg kawg nkaus thermal conductivity thiab qhov sib txuam qhov tsawg kawg nkaus qhov ntom ntom ntawm qhov sib txawv ntawm qhov kub thiab txias, thiab qhov ntim ntom ntom sib haum rau qhov tsawg kawg nkaus thermal conductivity nce nrog qhov kub thiab txias.
Kev nkag siab zoo thiab ua raws li cov cai saum toj no yog qhov tseem ceeb heev rau kev siv daim pam ceramic fiber ntau. Lub thermal rwb thaiv tsev kev ua tau zoo ntawm ceramic fibers tsuas yog siv cov thermal rwb thaiv tsev nyhuv ntawm cov huab cua nyob rau hauv lub pores ntawm cov khoom. Thaum qhov tshwj xeeb lub ntiajteb txawj nqus ntawm cov khoom fiber ntau yog qhov tsis tu ncua, qhov porosity ntau dua, qhov ntim tsawg dua. Thaum lub pob slag cov ntsiab lus tsis tu ncua, qhov cuam tshuam ntawm qhov ntim ntom ntawm thermal conductivity tiag tiag yog hais txog kev cuam tshuam ntawm porosity, pore loj thiab pore zog ntawm thermal conductivity.
1 Thaum lub ntim ceev yog<96Kg/m3
Vim qhov txhim kho oscillating convection thiab hluav taws xob hluav taws xob hloov hluav taws xob ntawm cov roj hauv cov qauv sib xyaw, cov thermal conductivity txo qis nrog lub ntim ntom, thiab qhia tau tias muaj kev sib raug zoo ntawm kev ua haujlwm.
2 When the volume density is >96kg/m3
Raws li cov ntim ntom ntom ntom ntxiv, qhov hws tau kaw hauv cov fiber ntau, cov cua ntws hauv cov fiber ntau dua (thermal kuj nce), thiab tib lub sijhawm, Cov hluav taws xob hluav taws xob hloov hluav taws xob los ntawm phab ntsa pore kuj txo qis raws li, yog li txo cov thermal conductivity.
3 Thaum lub ntim ntim nce mus rau qee qhov ntawm 240 ~ 320Kg / m3
Thaum cov ntaub qhwv cov ntaub qhwv lub ntsej muag nce mus rau qee qhov ntawm 240 ~ 320Kg / m3, cov ntsiab lus sib cuag ntawm cov khoom fiber ntau nce, kom cov fiber ntau nws tus kheej tsim ib tug choj, thiab cov cua kub hloov mus los ntawm tus choj. Qhov thib ob, qhov nce hauv cov ntsiab lus sib txuas ntawm cov khoom fiber ntau ua rau cov nyhuv damping ntawm lub qhov hws ntawm cov cua sov hloov mus, ua rau cov thermal conductivity tsis txo qis thiab muaj kev nce ntxiv. Yog li ntawd, cov ntaub ntawv ntxeem tau fiber ntau muaj qhov pom zoo ntim ntom nrog qhov tsawg kawg nkaus thermal conductivity. Qhov ntim ntom ntom ntawm ceramic fiber nyob rau ntawm qhov kub ntawm txawv teb chaws txheej ceramic fiber phab ntsa linings yog 130 ~ 160Kg / m3. Qhov ntim ntom ntom ntawm ceramic fiber nyob rau ntawm qhov kub ntawm qhov sib xyaw ua ke ntawm cov khoom siv hluav taws xob yog 200 ~ 240Kg / m3.
Qhov ntim ntom ntom ntawm cov khoom fiber ntau ntawm txhua txheej tom qab qhov kub ntawm lub qhov cub phab ntsa txo qis, vim tias nyob rau hauv qhov kub thiab txias, qhov degree ntawm thermal conductivity ntawm ceramic fibers txo nrog nce ntim ceev yog qhov tseem ceeb tshaj li qhov kub thiab txias. Cov txheej txheem fiber ntau nrog txhua txheej hauv cov thickness kev taw qhia sib phim raws li qhov ntom ntom tuaj yeem tswj tau cov thermal tsis sib xws hauv cov thickness kev taw qhia ntawm lub qhov cub hauv ob sab phlu. Nyob rau hauv tib lub thermal tsis kam, nws tuaj yeem txuag kev siv fiber ntau thiab txo cov nqi siv hluav taws xob.
