Ndi zinthu ziti zomwe zimakhudza kulemera kwa mullite refractory njerwa?

Bulk density index of mullite refractory njerwa ndi chithunzithunzi chokwanira cha kuchuluka kwa pore ndi mchere wa njerwa za mullite. Popanga, popeza kuchuluka kwa njerwa za mullite ndikosavuta kudziwa, nthawi zambiri amagwiritsidwa ntchito ngati njira yoweruza kuchuluka kwa sintering. Pali zinthu ziwiri zomwe zimakhudza kulemera kwa njerwa za mullite refractory:

1. Kachulukidwe kachulukidwe ka aluminiyamu ndi kukula kwa tinthu ta aluminiyamu wa njerwa za mullite;

2. Kulamulira kwa kupanga. Choncho, kupanga mullite refractory njerwa, makalasi a zipangizo ayenera mosamalitsa anasankha kulamulira tinthu kukula. Popanga, kukakamiza kwa njerwa yosindikizira njerwa kuyenera kuyendetsedwa, ndipo kuwombera kwa njerwa za mullite refractory kuyenera kuyendetsedwa moyenera.

Kudziwa kachulukidwe ka njerwa zokhotakhota kungatithandize kumvetsetsa ngati njerwa za mullite zili zowundana, komanso kumvetsetsa kulemera kwa njerwa za mullite kuchokera m’mbali kungatithandize kugula njerwa zomangira.
