Chong Hing glass beads glass beads outlined expansion is an inorganic glassy mineral materials, through multi-level silicon carbide electric heating tube production technology processing, irregular spherical particles, the internal structure of the porous cavity , glassy surface of the closure, shiny smooth, stable physical and chemical properties, with light, thermal insulation, fire resistance, high temperature, anti-aging, small water absorption and other outstanding features, can replace ash floating beads, glass beads, perlite , polystyrene particles, and many other traditional lightweight aggregate used in different Products. Is an environmentally friendly high-performance new inorganic lightweight insulating material. Chong Hing chemical composition of glass beads: about Silica SiO2 68-74% Al2O3 12% alumina, iron oxide Fe2O3 0.5-3.6% calcium oxide, magnesium oxide MgO 0.3% CaO 0.7-1.0% K2O 2-3% potassium oxide Sodium Na2O 4-5% water H2O 2.3-6.4% Chong Hing glass beads Physical properties: size (mm): 0.5-1.5 density (kg / m3): 80-350 balling rate: 80-95% of the surface of vitrified Rate: ≥95% Thermal conductivity (w / mk): 0.0284-0.05 water absorption (measured% vacuum filtration method): 20% -50%, the strength of the cylinder pressure (1Mpa pressure volume loss rate%): 38% -46 % refractoriness: 1208-1360 ℃ Operating Temperature: 800 ℃ Chong Hing glass beads application of alternative fly ash floating beads, glass beads, perlite, polystyrene particles, and many other traditional lightweight aggregate, used in industrial , agriculture, chemical industry, metallurgy, building materials and many other areas. Chong Hing glass beads Scope 1. Suitable for concrete, interior and exterior insulation aerated concrete block, brick, sand-lime brick wall. 2. The roof insulation. 3. The energy-saving old buildings. 4. basement, garage, fire exits, granary, stairwells, factories and other fire insulation works. The factory provides a variety of uses zeolite powder, bentonite, lithium bentonite, sodium bentonite, perlite gardening, air separation plant with perlite, do washing powder with a pearlescent sand, perlite filter aids, perlite insulation board, construction with glass beads, perlite Cleaner, opening perlite, obturator perlite, expanded perlite and other non-metallic mineral products, according to customer request production of various indicators of perlite products.
