The Application and the Function of the Glass Beads
The road marking glass beads are a kind of fine glass beads formed by melting glass sand, which served as a raw material after high temperature melting. This glass bead is a colorless, transparent and bright sphere under the observe with the microscope, and there are no obvious bubbles or impurities. The road marking glass beads used in road markings have a refractive index between 1.50-1.65 and a particle size generally between 70 microns and 800 microns, so they can be also called glass beads for road reflection.
