Glass beads is an environmentally friendly new inorganic light insulation material, in addition to a lightweight, heat insulation, excellent fire performance, but also with no combustion, high strength, low water absorption, easy and good life long benefits. Special size products from selected ore, expanded in the electric heating mode, temperature and raw materials through the precise control of endurance, so that the product surface melting, stomatal closure, irregular spherical particles, the internal structure of the porous cavity, the surface of glass of closure, shiny smooth, very stable physical and chemical properties, the product can be used as light aggregate new building materials industry; as the light part of the refractory industry alternatives floating beads; has a very broad application prospects, can be widely used in industry, agriculture, building materials, chemical industry, metallurgy, light industry and other areas.
