High Alumina Ceramic Fiber Npog

High alumina ceramic fiber daim pam yog tsim los ntawm cov khoom siv tsis zoo, tsis muaj asbestos, tsis muaj tshuaj lom thiab tsis qab, siv sijhawm ntev hauv 1000-1350 ℃, yog cov khoom siv feem ntau siv cov paj rwb fiber ntau pam. High alumina ceramic fiber daim pam muaj cov ntsiab lus siab ntawm Al2O3, thiab cov khoom tseem ceeb yog Al2O3 thiab SiO2. Cov khoom tau ntim rau hauv cov thawv, thiab qib yog qib 1.

1.Description of High Alumina Ceramic Fiber Blanket:
Cov paj rwb fiber ntau tuaj yeem muab faib ua cov khoom siv aluminium silicate pam (siv qhov kub txog 1000 ℃ ~ 1300 ℃), cov pam uas muaj zirconium (siv qhov kub txog 1400 ℃), pam pam mullite (punched 1300 ℃ ~ 1450 ℃), zirconium-muaj rab koob -punched pam (siv kub 1400 ℃ ~ 1650 ℃). Cov khoom muaj purity siab, tsis thermal conductivity thiab kub tsis kam. Lawv tau siv dav hauv cov rwb thaiv tsev sab nrauv thiab txheej rwb thaiv tsev ntawm ntau yam khoom siv cua sov.
Cov khoom siv siab purity calcinedflint av nplaum raws li raw khoom.after melting hauv hluav taws xob rauv, txhaj tshuaj, txias thiab lattice compression molding.the cov khoom muaj tsawg impurities, siab zog, zoo toughness thiab tsis thermal conductivity. Nws yog cov khoom siv hluav taws xob zoo hluav taws xob thiab tau siv dav hauv qhov rwb thaiv tsev ntawm cov khoom cua sov.
