Fused Silica Mixes/Silica Mixes
By adding anti-explosion organic fiber during the production, the mixes can be used at high temperature directly and will not burst or crack;
Similar physical and chemical properties with those of conventional silica brick, SiO2≥96%, Fe203≤0.6%;
High cold crushing strength,after drying the strength can exceed 20Mpa and higher than25Mpa when under temperature of 1300℃:
High adhesive strength for gunning repair,adhesive percentage can reach more than 80%;
Easy for Installation.lt can be used just by adding 10% ~ 14% water.
By ramming or gunning, it shows better performance together with zero expansion silica brick ZES-99 for hot repair of glass furnace.
