Fiber yumbu, wanda kuma aka sani da fiber refractory, wani nau'in abu ne na insulating kayan da aka yi daga inorganic fibrous kayan kamar alumina silicate ko polycrystine mullite. Yana nuna kyawawan kaddarorin thermal, yana mai da shi mashahurin zaɓi don aikace-aikacen zafi daban-daban. Anan akwai wasu mahimman kaddarorin thermal na yumbun fiber:
1. Thermal Conductivity: Ceramic fiber yana da ƙananan halayen thermal, yawanci daga 0.035 zuwa .052 W/mK (watts da mita-kelvin). Wannan ƙananan ƙarancin zafin jiki yana ba da damar fiber don rage yawan canja wurin zafi ta hanyar gudanarwa, yana mai da shi ingantaccen kayan kariya.
2. Thermal Stability: Ceramic fiber yana nuna nagartaccen kwanciyar hankali na thermal, ma'ana yana iya jure matsanancin yanayin zafi ba tare da rasa kaddarorin rufewa ba. Yana iya tsayayya da yanayin zafi har zuwa 1300 ° C (2372) har ma mafi girma a wasu maki.
3. Resistance Heat: Saboda babban wurin narkewa, fiber yumbu yana da matukar juriya ga zafi. Yana iya jure wa yanayin zafi mai tsanani ba tare da nakasu ba, ko lalacewa. Wannan dukiya ta sa ya dace da aikace-aikace a cikin yanayin zafi mai zafi.
4. Heat Capacity: Ceramic fiber yana da ƙarancin ƙarfin zafi, ma'ana yana buƙatar ƙarancin zafi sama ko sanyi. Wannan kadarar tana ba da damar saurin amsawa lokacin da canjin yanayi ya faru.
5. Ayyukan Insulating:Ceramic fiberyana ba da kyakkyawan aikin rufewa ta hanyar rage canjin zafi ta hanyar gudanarwa, vection, da radiation. Yana taimakawa wajen kiyaye yanayin zafi, inganta ingantaccen makamashi, kuma yana rage yawan asarar zafi.
Gabaɗaya, kaddarorin thermal na fiber yumbu sun sanya shi zaɓin da aka fi so don aikace-aikacen zafin jiki mai yawa. Yana ba da ingantacciyar rufi, kyakkyawan kwanciyar hankali na thermal, da dorewa a cikin buƙata.
