Ceramic fiber ntau cov khoom siv hluav taws xob thermal rwb thaiv tsev, pob zeb wool thermal rwb thaiv tsev khoom thiab iav ntaub plaub thermal rwb thaiv tsev cov khoom tam sim no tau dhau los ua kev txhawj xeeb txog cov ntaub ntawv thermal rwb thaiv tsev. Ntau yam khoom siv thermal rwb thaiv tsev yog siv hauv tsev neeg, kev lag luam, thiab cov tsev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj neeg coob. Cov kev xav tau rau cov khoom siv hluav taws xob thiab cov thermal rwb thaiv tsev yog qhov nruj dua. Niaj hnub no, Aladdin yuav coj koj los ua tib zoo txheeb xyuas qhov sib txawv thiab daim ntawv thov ntawm peb cov khoom siv hluav taws xob thermal.
01 Qhov sib txawv ntawm cov txheej txheem ntau lawm
Ceramic fiber ntau paj rwb yog ib hom fiber ntau lub teeb refractory khoom, lub ntsiab Cheebtsam yog Al2O3, SiO2, nws yog ib hom calcined thiab melted tawv av nplaum mas muaj li ntawm kaolin thiab coke gemstones, thiab yog tshuab mus rau hauv fibers los ntawm high-pressure cua txhaj los yog peb-roller spinning. Ib qho ntshiab inorganic fiber ntau.
Pob zeb wool khoom yog ua los ntawm refined basalt raws li lub ntsiab raw khoom, uas yog melted nyob rau hauv high kub thiab ua rau inorganic fibers los ntawm high-ceev centrifugal khoom. Tom qab ntawd cov ntaub ntawv tshwj xeeb thiab cov hmoov av pov thawj tau ntxiv, thiab cov kev xav tau muab tso rau ntawm txoj siv viav vias thiab cov qauv kev npaj fiber ntau tau hloov pauv los ntawm cov cuab yeej tshwj xeeb. Lub teeb yuag thermal rwb thaiv tsev cov khoom ua los ntawm kev kho.
iav ntaub plaub kuj yog ib qho inorganic fiber. Ntuj ores xws li quartz xuab zeb, limestone thiab dolomite yog siv los ua cov ntaub ntawv tseem ceeb, thiab qee cov khoom siv tshuaj xws li dej qab zib tshauv thiab borax yog yaj rau hauv iav. Nyob rau hauv lub xeev melted, nws yog tshuab mus rau hauv floc zoo li fibers los ntawm kev siv sab nraud quab yuam tshuab. Xws li qhov khoob tuaj yeem suav tias yog qhov pores, yog li ntawd, iav ntaub plaub tuaj yeem suav tias yog cov khoom ntxeem tau nrog cov thermal rwb thaiv tsev zoo thiab lub suab nqus.
02 Qhov sib txawv ntawm cov khoom ua haujlwm
Ceramic fiber wool, pob zeb wool thiab iav ntaub plaub txhua yam muaj qhov zoo ntawm cov khoom siv tsawg tsawg, cov ntsiab lus tsis tshua muaj slag pob, tsis tshua muaj thermal conductivity thiab zoo suab rwb thaiv tsev.
Ceramic fiber ntau paj rwb muaj qhov zoo dua nyob rau hauv cov nqe lus ntawm kev pab cuam lub neej ntev thiab siab fiber ntau toughness;
Lub thermal conductivity ntawm ceramic fiber paj rwb yog qis dua;
Kev siv kub ntawm cov paj rwb fiber ntau yog qhov siab tshaj, siab tshaj 1000 degree, feem ntau siv hom 1050, 1260 thiab 1400.
Qhov siab tshaj plaws siv kub ntawm pob zeb ntaub plaub yog hais txog 600 degree, thaum iav ntaub plaub tsuas yog hais txog 260 degree.
03 Qhov sib txawv ntawm cov khoom siv
iav ntaub plaub - feem ntau yog siv rau thermal rwb thaiv tsev qhov chaw hauv qab 200 degree, feem ntau yog siv rau thermal rwb thaiv tsev ntawm cov vaj tse lossis cov kav dej kub;
Pob zeb wool feem ntau yog siv rau thermal rwb thaiv tsev qhov chaw nrog qhov kub ntawm 500 degree, thiab feem ntau yog siv rau thermal rwb thaiv tsev ntawm high-temperature tshav kub kav los yog cov khoom siv fais fab;
Ceramic fiber ntau paj rwb tuaj yeem siv rau kev rwb thaiv tsev kub ntawm 200 degree, nruab nrab kub rwb thaiv tsev ntawm 500 degree, thiab hluav taws kub rwb thaiv tsev ntawm 1000 degree.
