Descripción del producto

Floating bead is a kind of can float to the surface of fly ash hollow ball, are pale, thin wall hollow, weight is light, unit weight of **0 kg/m3 (heavy), and **8.8 kg/m3 (light), particle size is about 0.1 mm, closed and smooth surface, small thermal conductivity, refractoriness ***0 ℃ or higher, is a good insulation refractory material, is widely used in the production of lightweight castable and oil drilling.Drift beads of the chemical composition is given priority to with silica and 3 oxidation 2 aluminium, with a fine grain, hollow, qualitative light, high strength, wear resistance, high temperature resistant, thermal insulation, insulation, flame retardant, and other features, is one of the raw materials are widely used in refractory industry.
