Rarraba bulo mai nauyi mai nauyi don kilns ɗin gilashi 1

Ana iya rarraba bulo mai ɗaukar nauyi don murhun gilashin zuwa nau'ikan 6 bisa ga nau'ikan albarkatun su daban-daban. Wadanda aka fi amfani dasu sune tubalin silica marasa nauyi da tubalin diatomite. Tubalo masu nauyi masu nauyi suna da fa'idodi na kyakkyawan aikin rufewar zafi, amma juriyarsu, juriya, da juriya na zafin zafi ba su da kyau, don haka ba za su iya yin hulɗa kai tsaye tare da narkakkar gilashin ko harshen wuta ba.

1. tubalin siliki mara nauyi. Silica insulation tubali mai nauyi samfuri ne mai hana ruwa wanda aka yi daga silica a matsayin babban kayan albarkatun ƙasa, tare da abun ciki na SiO2 na ƙasa da 91%. Girman tubalin silica mai nauyi mai nauyi shine 0.9 ~ 1.1g/cm3, kuma yanayin zafinsa shine rabin na tubalin silica na yau da kullun. Yana da kyau thermal girgiza juriya, da tausasawa zafin jiki a karkashin kaya iya isa 1600 ℃, wanda ya fi girma fiye da na yumbu rufi tubalin. Saboda haka, matsakaicin aiki zafin jiki na silica rufi tubalin iya isa 1550 ℃. Ba ya raguwa a yanayin zafi mai zafi, har ma yana da ɗan faɗaɗawa. Haske silica tubali ne kullum samar da crystalline Quartzite a matsayin albarkatun kasa, kuma combustible abubuwa kamar coke, anthracite, sawdust, da dai sauransu ana kara a cikin albarkatun kasa samar da porous tsarin da gas kumfa hanyar kuma za a iya amfani da su samar da porous tsarin.
2. Diatomite tubalin: Idan aka kwatanta da sauran bulogin rufi masu nauyi, bulogin diatomite suna da ƙananan ƙarancin zafin jiki. Yanayin aiki ya bambanta da tsabta. Yawan zafin jiki na aiki yana ƙasa da 1100 ℃ saboda raguwar samfurin yana da girma a yanayin zafi. Abubuwan da ake amfani da su na bulo diatomite suna buƙatar a harba su a cikin zafin jiki mafi girma, kuma ana iya canza silicon dioxide zuwa quartz. Hakanan za'a iya ƙara lemun tsami a matsayin mai ɗaure da ma'adinai don inganta canjin ma'adini a lokacin harbe-harbe, wanda ke da amfani don inganta yanayin zafi na samfurin da rage raguwa a yanayin zafi.
