Fiber ya refractory, yomwe imadziwikanso kuti ceramic fiber, ndiyomwe imagwiritsidwa ntchito popanga matenthedwe otsika kwambiri komanso kutentha kwambiri komanso kupulumutsa mphamvu kuwonjezera pa nano-matadium.Zili ndi ubwino wambiri, monga kulemera kwa thupi, kukana kutentha kwapamwamba, kutsekemera kwabwino kwa kutentha kwa kutentha, kumanga kosavuta, ndi zina zotero.Poyerekeza ndi njerwa zomangira zachikhalidwe, zotayira zomangira ndi zida zina, midadada yopindika ya ceramic ili ndi maubwino otsatirawa:

a) Kulemera kopepuka (kuchepetsa kuchuluka kwa ng'anjo ndi kukulitsa moyo wang'anjo): Ulusi wa refractory ndi mtundu wazinthu zopangira ulusi.Chovala chogwiritsidwa ntchito kwambiri cha refractory fiber chimakhala ndi kachulukidwe wa 96 ~ 128kg/m3, pomwe kachulukidwe kagawo kagawo kakang'ono ka fiber fiber bulangeti ndi pakati pa 200 ~ 240kg/m3, ndipo kulemera kwake ndi 1/5 ~ 1/ 10 ya njerwa zowala zowoneka bwino kapena amorphous, ndi 1/15 ~ 1/20 yazinthu zolemetsa zolemetsa.Zitha kuwoneka kuti zida zopangira ng'anjo yamoto zimatha kuzindikira ng'anjo yopepuka komanso yothandiza kwambiri, kuchepetsa kuchuluka kwa ng'anjo ndikuwonjezera moyo wang'anjo.

b) Kutentha kochepa (kuchepa kwa kutentha ndi kukwera msanga kwa kutentha): Kutentha kwa zinthu za ng'anjo nthawi zambiri kumakhala kolingana ndi kulemera kwa ng'anjo.Kutentha kochepa kumatanthawuza kuti ng'anjoyo imatenga kutentha pang'ono panthawi yobwerezabwereza, ndipo kuthamanga kwa kutentha kumathamanga.Kutentha kwa ulusi wa ceramic ndi 1/10 yokha ya zingwe zopepuka zosagwira kutentha ndi njerwa zopepuka, zomwe zimachepetsa kwambiri kugwiritsa ntchito mphamvu pakuwongolera kutentha kwa ng'anjo.Makamaka kutentha ng'anjo ndi ntchito yapakatikati, imakhala ndi mphamvu yopulumutsa mphamvu

c) Low matenthedwe madutsidwe (kutsika kutentha kutaya): pamene pafupifupi kutentha kwa ceramic fiber chuma ndi 200C, matenthedwe madutsidwe ndi zosakwana 0. 06W/mk, zosakwana 0 pa 400 ° pafupifupi.10W/mk, pafupifupi 1/8 wa kuwala kutentha zosagwira amorphous zakuthupi, ndi za 1/10 wa njerwa kuwala, pamene matenthedwe madutsidwe wa ceramic zinthu CHIKWANGWANI ndi katundu wolemera moto zosagwira akhoza kunyalanyazidwa.Choncho, matenthedwe kutchinjiriza zotsatira za refractory fiber zipangizo ndi ofunika kwambiri.

d) Kumanga kosavuta (palibe cholumikizira chowonjezera chomwe chimafunikira): ogwira ntchito yomanga atha kutenga ntchitoyo pambuyo pa maphunziro oyambira, komanso chikoka cha luso la zomangamanga pakupanga kwamphamvu kwa kutentha kwa ng'anjo.

e) Osiyanasiyana ntchito: Ndi chitukuko cha kupanga ndi ntchito luso CHIKWANGWANI refractory, refractory ceramic CHIKWANGWANI mankhwala anazindikira serialization ndi functionalization, ndipo mankhwala akhoza kukwaniritsa zofunika ntchito zosiyanasiyana kutentha giredi kuchokera 600 ° C mpaka 1400 ° C. Ku mbali ya kapangidwe ka zinthu, pang'onopang'ono anapanga zosiyanasiyana processing yachiwiri kapena kwambiri processing mankhwala ku chikhalidwe ceramic CHIKWANGWANI thonje, ceramic CHIKWANGWANI bulangeti, CHIKWANGWANI anamva mankhwala kuti refractory CHIKWANGWANI gulu, ceramic CHIKWANGWANI bolodi, ceramic CHIKWANGWANI mbiri mankhwala, ceramic CHIKWANGWANI pepala, fiber nsalu ndi mitundu ina.Iwo akhoza kukwaniritsa zosowa za ng'anjo zosiyanasiyana mafakitale m'mafakitale osiyanasiyana kwa refractory ceramic CHIKWANGWANI mankhwala.

f) Kukana kwamphamvu kwamafuta: gawo lopindika la CHIKWANGWANI limakana kwambiri kusinthasintha kwa kutentha.Poganizira kuti zida zotenthetsera zimatha kupirira, chingwe cha ng'anjo ya fiber folding chimatha kutenthedwa kapena kukhazikika pa liwiro lililonse.

o) Kukaniza kugwedezeka kwamakina (ndi kusinthasintha ndi kusinthasintha): bulangeti la fiber kapena bulangeti la fiber ndi losinthika komanso lotanuka, ndipo silosavuta kuwonongeka.Ng'anjo yonse itatha kuyika sikophweka kuti iwonongeke ikakhudzidwa kapena kugwedezeka ndi kayendedwe ka msewu.

h) Palibe kuyanika ng'anjo: popanda njira zowumitsa ng'anjo (monga kuchiritsa, kuyanika, kuphika, kuumitsa ng'anjo yovuta komanso njira zotetezera nyengo yozizira), ng'anjo ya ng'anjo imatha kugwiritsidwa ntchito pomanga.

1) Kuchita bwino kwa mawu otchinjiriza (kuchepetsa kuwonongeka kwa phokoso): chipika chopinda cha ceramic fiber chingathe kuchepetsa phokoso lafupipafupi ndi mafupipafupi osakwana 1000 Hz.Kwa mafunde amawu osakwana 300 Hz, luso la kutchinjiriza kwamawu limaposa zida zodziwika bwino zotchinjiriza, ndipo zimatha kuchepetsa kwambiri kuwononga phokoso.

j) Kutha kuwongolera kwamphamvu: kukhudzika kwamphamvu kwamafuta a ceramic fiber lining kumatha kusinthiratu kuwongolera kowotcha ng'anjo.

k) Kukhazikika kwa Chemical: mankhwala a ceramic fiber folding block ndi okhazikika.Kupatula phosphoric acid, hydrofluoric acid ndi alkali wamphamvu, zidulo zina, alkalis, madzi, mafuta ndi nthunzi sizikokoloka.
