Samfuran Juriya na Ƙarfin zafi
010203
Corundum Bricks-Hengli
Siffofin
Tubalin Corundum, wanda kuma aka sani da bulogin alumina, samfuran alumina ne masu jujjuyawa da abubuwa masu mahimmanci da yawa:
1. **Mafi Girma: **Yawanci ya ƙunshi fiye da 90% alumina (Al2O3), yana tabbatar da kyawawan kaddarorin haɓakawa.
2. **Hanyoyin Juriya na Zazzabi: **Yana iya jure yanayin zafi har zuwa 1900 ° C, yana sa su dace da yanayin yanayin zafi mai tsananin buƙata.
3. **Karfin Injini: **Bulogin Corundum suna da ƙarfin matsawa mai ƙarfi da juriya mai kyau, yana ba su damar ɗaukar nauyi mai nauyi da yanayin abrasive.
4. ** Juriyar Lalacewa: **Suna tsayayya da lalata daga slags, acids, alkalis, da sauran sinadarai, suna tsawaita rayuwarsu a cikin yanayi mara kyau.
5. **Rashin Ƙarfi: **Ƙananan porosity yana taimakawa hana shigar da narkakkar kayan aiki da iskar gas, haɓaka karɓuwa da kaddarorin zafin jiki.
6. ** Kwanciyar Hankali: **Suna nuna kyakkyawan kwanciyar hankali na thermal da juriya ga girgizar zafi, wanda ke da mahimmanci ga tafiyar matakai da ke tattare da saurin canjin zafin jiki.
7. ** Kwanciyar Hankali: **Babban abun ciki na alumina yana tabbatar da cewa tubalin suna kula da siffar su da girma a yanayin zafi mai yawa, yana hana gazawar tsarin.
Waɗannan fasalulluka sun sa tubalin corundum ya dace don amfani a aikace-aikace masu zafi daban-daban, gami da tanderun fashewa, murhu mai zafi, tulun ƙarfe, da sauran tanderun masana'antu da kilns.
Aikace-aikace na yau da kullun
An yi amfani da shi sosai a cikin masana'antu kamar taki, yumbu na lantarki, petrochemical, karfe, fondry, gami karfe, refractories, da dai sauransu. Aikace-aikace na yau da kullun kamar mai gyara na biyu da na'urar janareta na gas, tallafin gado mai kara kuzari, tanderun shigar da tashar, wutar makera, da dai sauransu.
