Product Description
Product Overview:
Silicious heat-insulating and fire-resistant brick is a product made by mixing bleaching beads, silicon powder and binder in a certain ratio, and then pressing and molding, and firing at high temperature. According to the physical and chemical indicators are divided into GGR-1.0, GGR-1.1, GGR-1.15, GGR-1.2 four brands. Mainly used for heat preservation of glass industry kiln, saving energy and reducing consumption.
