Fiber yokonzansoMwanjira ya kutentha imatha kugawidwa mu zinthu zingapo, kusamutsa ma radiation pamtunda wopota kutentha ndi kutentha kwa fiber yolimba, pomwe kusinthitsa kutentha kwa mpweya sikunyalanyazidwa. Kuchulukitsa kwakukulu ndi kutentha kumakhala ndi ubale wokondwerera, kutentha kwambiri, kumachepetsa kuchuluka kwa mlanduwo, kuchuluka kwa ma radiation kutentha kumawonjezeka. Kuti mupange zinthu zodziwika bwino, kachulukidwe kambiri nthawi zambiri umakhala pansi pa 0,25g / CM ..
Ngati ndi chiphunzitso chakuti kuchuluka kwa kachulukidwe kambiri, kusachita bwino ndi kwakukulu, kuchuluka kwa kachulukidwe kambiri ndi kabwino kwambiri kutentha ndikochepa; Izi sizilinso mzere ndi momwe ziliri, monga slag yokhala ndi yosiyana, ngakhale ngati kuchuluka kwa kuchuluka kwake ndi kofanana, kotero kuti chidwi chilichonse sichikhala chofanana, ndiye kuti padzakhala kusiyana kwanyengo. Komabe, masitepewo amatha kufotokozedwa mwachidule motere.
1. Mafuta aulusi wokhozaKuchepetsa ndi kuchuluka kwa kuchuluka, ndipo kuchepa kumachepetsa pang'onopang'ono, koma pamene kuchuluka kwake kumafika pamlingo wina, zochititsa thupi sizimacheperachepera ndipo zimakhala ndi chizolowezi chowonjezeka.
2. Pamatenthedwe osiyanasiyana, pamakhala mawonekedwe ochepera komanso ogwirizana. Tchuluzo chofanana ndi mawonekedwe ochepera amawonjezeka ndi kutentha kwambiri.
3. Kwa kachulukidwe kofanana, kuwonjezeredwa kwamafuta kumasiyanasiyana ndi kukula kwa ma pores.
(1) Kukula kwa Pure 0.1mm.
0c kulowa = 0.0244W / (m. K) 100c pamene λ = 0.0314W / (m. K)
(2) Ziphuphu 2mm.
Mu 0c = 0.0314W / (m, k, k) λ = 0. 0512w / (m. K) ku 100c. K)
Mulingo wapamwamba wa 1mm, kutentha kumatuluka 0c mpaka 500c, mtengo wake wamafuta umawonjezera ma 5.3; Mulingo wapamwamba wa 5mm, matenthedwe amatuluka kuchokera pa 0c mpaka 500c, mtengo wake wamafuta umawonjezera nthawi 11.7. Chifukwa chake, zokulirapo pores mu ulusi wotsimikizira, wocheperako wolingana ndi kuchuluka, ndipo wochititsa chidwi umawonjezeka.
