Nawa mullite tubalin rufi mai nauyi mai nauyi zai iya jurewa?
Bull ɗin rufi na Mullite sabon salo ne na kayan ƙyama, wanda zai iya tuntuɓar harshen wuta kai tsaye. Yana da halayen juriya mai tsananin zafi, babban haske, ƙarancin ƙarancin zafi, da tasirin ceton makamashi mai mahimmanci. Mullite tubalin ruɓaɓɓen nauyi mai nauyi yana da halayen kyakkyawan aikin zafin zafi da ƙarancin farashi. Za a iya amfani da su don yin rufi, wanda ba kawai zai iya rage ingancin wutar makera ba, ajiye ƙonewa, amma kuma ya tsawaita rayuwar sabis na rufin tanderu da rage farashin kulawa.
Mullite tubalin ruɓaɓɓen nauyi mai ƙarfi an yi shi ne da bauxite, yumɓu, “duwatsu uku”, da dai sauransu, ta hanyar ƙirƙirar babban adadin haɗin kai ko rufe ramuka a cikin kayan kayan ko tsarin zafin zafi mai zafi.
Abubuwan fasali na tubalin mullite mai sauƙin nauyi:
Nawa mullite tubalin rufi mai nauyi mai nauyi zai iya jurewa? Babban zafin juriya na bulo mai rufi na mullite zai iya kaiwa sama da 1790 ℃. Zazzabi mai laushi yana farawa zafin jiki shine 1600-1700 ℃, ƙarfin matsin lamba na yau da kullun shine 70-260MPa, juriya na girgiza yana da kyau, ƙarfin yana da girma, ƙima mai saurin zazzabi yana da ƙarancin ƙarfi, maƙasudin faɗaɗa yana da ƙarancin ƙarfi karami ne, kuma slag na acid yana da tsayayya. Kuma yana iya rage ƙimar jikin tanderu mai tsananin zafi, canza tsarin, adana kayan, adana makamashi, da haɓaka ingancin samarwa.
