Road reflective glass beads is a kind of tiny glass beads made of glass sand (waste glass) after high temperature melting. It is spherical, colorless, transparent under the microscope, and with a refractive index of 1.50 between 1.64. The diameter is generally between 44 microns to 1400 microns. Currently in the domestic production of road reflective glass beads float process is the flame method.
Road reflective glass beads as road marking (paint) in reflective material, can improve road marking paint, Retroreflective performance, improve traffic safety at night, has to be determined for national transport sector. When driving at night, the lights shone on road signs online with glass beads, can lights and parallel light rays reflected back so that drivers see the way forward to improve traffic safety at night. Now, reflective glass beads have become a road safety products reflective material can not be replaced.
