Tej hub fiber ntau, tseem hu ua refractory fiber ntau, yog hom ntawm insulating cov ntaub ntawv ua los ntawm inorganic fibrous cov ntaub ntawv xws li alumina silicate lossis polycrystine mullite. Nws ua rau cov khoom siv ua hluav taws xob zoo heev, ua rau nws muaj kev xaiv nrov rau ntau daim ntaub ntawv hightemperature. Nov yog qee qhov tseem ceeb thermal muaj zog ntawm ceramic fiber:
1. Thermal conductivity: tej hub fiber muaj qhov tsis muaj zog thermal, feem ntau yog xws li 0.035 rau .052 W / MK (WATTS ib meter-Kelvin). Qhov no tsawg thermal no tso cai fiber ntau kom muaj zog kom txo cov cua sov kom cov khoom siv, ua nws cov khoom siv insulating, ua rau cov khoom siv insulating.
2. Thermal stability: Ceramic Fiber Cov Khoom Taw Qhia Kev Tshwj Xeeb Thermal stability, lub ntsiab lus nws tuaj yeem tiv taus cov insulating cov khoom. Nws tuaj yeem tiv thaiv qhov kub thiab txias li 1300 ° C (2372) thiab tau siab dua hauv qee qib.
3. Cua sov kuj: Vim nws lub siab melting taw tes, tej hub fiber yeej tiv taus kub. Nws tuaj yeem tiv thaiv kev raug mob kom muaj zog kub yam tsis muaj deformation, lossis kev cuam tshuam. Cov cuab yeej no ua rau nws haum rau kev siv hauv qhov chaw kub-ib puag ncig.
4. Thaum Tshav Kub Kub muaj peev xwm ua kom muaj fiber ntau muaj peev xwm ua kom sov muaj peev xwm, lub ntsiab lus nws yuav tsum muaj zog tsawg dua los yog txias. Cov cuab yeej no tso cai rau cov sijhawm sai thaum lub sijhawm ntsuas kub thaum kub.
5. Insulating kev ua tau zoo:Tej hub fiberMuaj kev tswj hwm zoo tshaj plaws ntawm kev tswj hwm kev ua haujlwm los ntawm kev txo cov cua sov los ntawm kev conduction, vection, thiab hluav taws xob. Nws pab tswj cov kev kub ntxhov ib txwm, txhim kho kev txuag hluav taws xob, thiab txo qis kom kub.
Zuag qhia tag nrho, cov thermal cov khoom muaj ntawm ceramic fiber ua nws txoj kev xaiv xaiv rau ntau cov kev siv kub siab. Nws muab cov rwb thaiv tsev zoo, zoo heev thermal stability, thiab durability nyob rau hauv kev xav tau.
