Lub thermal conductivity ntawm cov ntaub pua plag fiber yog dab tsi?

Daim pam ceramic fiber yog cov khoom siv rwb thaiv tsev uas siv tau ntau yam thiab siv dav hauv ntau yam kev siv los muab kev rwb thaiv tsev zoo heev. Ib qho ntawm cov yam ntxwv tseem ceeb uas ua rau daim pam ceramic fiber ua tau zoo yog nws cov thermal conductivity qis.

Qhov thermal conductivity ntawm cov ntaub pua plag fiber feem ntau yog txij li 0035 txog 0.052 W / mK (watts ib 'meter'-kelvin). Qhov no txhais tau tias nws muaj peev xwm ua kom sov qis dua. Qhov thermal conductivity qis dua, cov khoom rwb thaiv tsev zoo dua ntawm cov khoom.
Qhov ua kom cov cua sov qis ntawm cov ntaub pua plag fiber yog qhov tshwm sim ntawm nws cov khoom sib xyaw tshwj xeeb. Nws yog ua los ntawm cov fibers uas tiv taus kub siab, xws li alumina silicate lossis polycrystalline mullite, uas muaj cov cua sov qis. Cov fibers no khi ua ke siv cov khoom siv binder los tsim cov qauv zoo li daim pam, uas ua rau nws cov khoom zoo dua.
Daim pam ua los ntawm cov khoom siv ceramicfeem ntau siv rau hauv cov ntawv thov uas qhov kev rwb thaiv cua sov yog qhov tseem ceeb, xws li hauv cov cub tawg, qhov cub, thiab cov boilers. Nws kuj tseem siv rau hauv kev lag luam aerospace, kev lag luam tsheb, thiab hauv kev ua thiab tsim khoom kub siab.
