Supply of thermal insulation floating beads and fire-resistant floating beads

Drift bead is a kind of fly ash hollow ball that can float on the water surface. It is gray white, thin and hollow in wall, very light in weight, with unit weight of 720kg/m3 (heavy), 418.8kg/m3 (light), particle size of about 0.1mm, closed and smooth in surface, small in thermal conductivity, and fire resistance ≥ 1610 ℃. It is an excellent temperature retaining refractory, It is widely used in the production of light castables and oil drilling. The chemical composition of floating beads silicon dioxide It is mainly composed of aluminum oxide, with fine particles, hollow, light weight, high height, wear resistance, high temperature resistance, thermal insulation, insulation and flame retardancy, and has been widely used as one of the raw materials of refractory materials.
