Koyaya, CCEWOOL samfuran fiber masu ratsa jiki suna da ƙarancin yanayin zafi, ƙarancin ajiyar zafi, da ƙarancin ƙarfi, waɗanda sune manyan dalilan aikace -aikacen su masu yawa a cikin murfin dumama. Halayen sune kamar haka:

1. Yanayin zafin zafin aiki mai fadi da sifofin aikace -aikace iri -iri
Tare da haɓaka ƙirar keɓaɓɓun yumɓu da fasaha na CCEWOOL, samfuran filayen yumbu na CCEWOOL sun sami daidaituwa da aiki. Dangane da yanayin zafi, samfuran na iya cika buƙatun yanayin zafi daban -daban daga 600 ℃ zuwa 1500 ℃. Dangane da ilimin halittar jiki, samfuran a hankali sun haɓaka iri-iri na sarrafa sakandare ko samfuran sarrafawa mai zurfi daga auduga na gargajiya, barguna, samfuran da aka ji zuwa madaidaitan fiber, allon allo, sassa masu siffa ta musamman, takarda, yadi na fiber da sauransu. Suna iya cika buƙatun tanderun masana'antu don samfuran fiber na yumbu a masana'antu daban -daban.
2. Ƙananan ƙarar girma:
Yawan ƙimar samfuran firam ɗin yumɓu gabaɗaya shine 96 ~ 160kg/m3, wanda shine kusan 1/3 na bulo masu nauyi da 1/5 na ƙyalli mai sauƙi mai sauƙi. Don sabon tanderun da aka ƙera, amfani da samfuran fiber na yumɓu ba kawai zai iya ajiye ƙarfe ba, har ma yana iya sauƙaƙewa/saukarwa da sufuri cikin sauƙi, yana haɓaka ci gaba a cikin fasahar makera ta masana'antu.
3. Ƙananan ƙarfin zafi da ajiyar zafi:
Idan aka kwatanta da tubalin da ke hana ruwa da bulo mai ruɓi, ƙarfin samfuran fiber na yumɓu ya yi ƙasa da yawa, kusan 1/14-1/13 na bulo mai ƙyalli da 1/7-1/6 na bulo na rufi. Ga tanderun irin kararrawar da ake sarrafa ta lokaci-lokaci, ana iya adana adadi mai yawa na man da ba a haɗa shi da shi ba.
4. Simple yi, gajeren lokaci
Kamar yadda bargo da yadudduka da keɓaɓɓun kayayyaki ke da madaidaiciyar elasticity, ana iya annabta adadin matsi, kuma babu buƙatar barin gidajen faɗaɗa yayin gini. Sakamakon haka, ginin yana da sauƙi kuma mai sauƙi, wanda ƙwararrun ma'aikata na yau da kullun za su iya kammala su.
5. Yin aiki ba tare da tanda ba
Ta hanyar ɗaukar murfin cikakken fiber, tanderun wuta za su iya yin zafi da sauri zuwa zafin zafin tsari idan ba a taƙaita shi da sauran abubuwan ƙarfe ba, wanda ke haɓaka ingantaccen amfani da tanderun masana'antu da rage yawan amfani da man da ba na samarwa ba.
6. Ƙarfi mai ƙarancin zafi
Filashin yumɓu yana haɗuwa da zaruruwa tare da diamita na 3-5um, don haka yana da ƙarancin yanayin zafi. Misali, lokacin da bargon fiber na aluminium mai nauyin 128kg/m3 ya kai 1000 ℃ a saman zafi, zafin canja wurin zafi shine 0.22 (W/MK) kawai.
7. Kyakkyawan kwanciyar hankali na sinadarai da juriya ga yaɗuwar iska:
Za'a iya lalata firam ɗin yumɓu kawai a cikin phosphoric acid, hydrofluoric acid, da alkali mai zafi, kuma yana da tsayayye ga sauran kafofin watsa labarai masu lalata. Bugu da ƙari, ana yin samfuran firam ɗin yumɓu ta hanyar ci gaba da ninƙaya barguna na yumbura a wani rabo na matsawa. Bayan an kula da farfajiyar, juriya na zaizayar iska zai iya kaiwa 30m/s.
