The difference between vitrified beads and hollow glass beads

by:Spring Glass     2021-02-27
Hollow glass beads are hollow glass spheres with tiny sizes, which are inorganic non-metallic materials. The typical particle size range is 10-180 microns, and the bulk density is 0.1-0.25 g/cm3. It has the advantages of light weight, low thermal conductivity, sound insulation, high dispersion, good electrical insulation and thermal stability. It is a kind of development in recent years. Two new lightweight materials with a wide range of uses and excellent performance have different appearances. The former is rougher and has a larger particle size. Vitrified microbeads are a kind of acidic vitreous lava minerals (turpentine ore), which are processed by special technology and production process to form internal porous and closed surface with vitrification. They are spherical and fine-diameter particles. It is a kind of high-performance The new inorganic lightweight thermal insulation material. The main chemical composition is Si02, AI203, CaO, the particle size is 0.1-2mm, the bulk density is 50-100kg/m3, and the thermal conductivity is 0.028-0.048W/m. K, floating rate is greater than 95%, ball vitrification rate is greater than 95%, water absorption rate is less than 50%, melting temperature is 1200℃
