Yashi Mullite
Bayanin samfur
Yashi mai yawawani abu ne mai jujjuyawa silicate na aluminium, gabaɗaya ana amfani dashi a cikin daidaitaccen aikin simintin bakin karfe. Refractoriness ne game da 1750 digiri. Mafi girman abun ciki na aluminium a cikin yashi mai yawa, raguwar abun ciki na ƙarfe, da ƙarami ƙura, mafi kyawun ingancin samfurin yashi na mullite. Yashi iri-iri ana yin shi ta hanyar zazzaɓi mai zafi na kaolin.
Siffofin:
1. Babban wurin narkewa, gabaɗaya tsakanin 1750 zuwa 1860 ° C.
2. Kyakkyawan kwanciyar hankali mai zafi.
3. Low thermal fadada coefficient.
4. High sinadaran kwanciyar hankali.
5. Ma'ana mai ma'ana girman rabo na barbashi yana ba da damar zaɓi da daidaitawa dangane da matakai daban-daban na simintin gyare-gyare da buƙatun simintin.
