1 Bambance-bambancen da ke tsakanin kayan haɓakar thermal da kayan refractory
Gabaɗaya magana, ƙasa 1570 ℃ ana kiransa kayan rufewa;Sama 1570 ℃ ne refractory abu.Na gargajiya kayan refractory gabaɗaya suna nufin nauyi wuta tubalin, castable, da dai sauransu, da girma yawa ne kullum 1000-2000kg/m3.
Abubuwan da ake amfani da fiber yumbu a bayyane suke, a ƙarƙashin yanayin kyakkyawan aikin haɓakar thermal, amma kuma yana da tsayayyar wuta mai kyau, kuma yana cikin kayan haske, rage nauyin tanderun, rage yawan shigarwa na gargajiya saboda goyon bayan nauyi. kayan cinyewa da babban adadin karfe.
2 zafi waya shrinkage
Fihirisar don kimanta juriyar zafi (zazzabin sabis) na samfuran fiber yumbu.Haɗin kai na ƙasashen duniya na samfuran fiber yumbu a ƙarƙashin dumama mara nauyi zuwa wani zafin jiki, adana zafi na tsawon sa'o'i 24 na ƙarancin layin zafin jiki yana nuna juriya na zafin yumbu.
Gwajin zazzabi na dumama darajar shrinkage waya ≤3% shine ci gaba da zafin sabis na samfuran fiber yumbu.A wannan zafin jiki, amorphous yumbu zaruruwa crystallize da girma sannu a hankali, da fiber kaddarorin ne barga da kuma roba.
Ƙimar raguwar waya mai zafi ≤4% gwajin zafin jiki don samfuran fiber yumbu suna amfani da zafin jiki.
3 Thermal watsin
Ƙarfafawar thermal wani nau'i ne na kayan jiki na jiki, wanda shine ma'auni na kayan kariya na thermal na yumbu fiber.
Ya dogara da tsarin samfuran fiber yumbu, ƙarancin girma, zafin jiki, yanayin tanderu, zafi da sauran dalilai.
Ceramic fiber shine cakuda fiber mai ƙarfi da iska tare da porosity na 93%.Babban adadin iska tare da ƙananan ƙarancin thermal yana cika a cikin pores, kuma ci gaba da tsarin cibiyar sadarwa na ƙananan ƙwayoyin cuta ya lalace, don samun kyakkyawan aikin adiabatic.Kuma ƙarami da diamita na pore, tare da jagorancin zafi mai gudana ta hanyar fiber mai ƙarfi da aka raba zuwa yanayin rufaffiyar adadin pores, mafi kyawun kayan aikin thermal na yumbu fiber.
4. Tasirin sinadaran sinadaran
Abubuwan sinadaran kai tsaye yana ƙayyade juriyar zafin fiber:
(1) Al2O3, SiO2, ZrO2, Cr2O3 da sauran tasiri masu tasiri ≥99%, babban zafin jiki oxide abun ciki, kai tsaye ƙayyade aikin yumbu fiber.
(2) Fe2O3, Na2O, K2O, MgO da sauran ƙazantar ƙasa da 1%, suna cikin ƙazantattun abubuwa masu cutarwa, kai tsaye suna haifar da lalacewar aikin fiber yumbura.
