Road reflective glass microbeads are meticulously crafted small spheres derived from the high-temperature melting of glass sand (recycled glass), serving as the innovative raw material. These microbeads possess a spherical form, appearing colorless and transparent when observed under a microscope, boasting a refractive index ranging between 1.50 and 1.64, with diameters generally spanning 44 microns to 1400 microns. Presently, China's predominant method for producing these reflective glass beads is the advanced flame floating technique. As a critical reflective component within road marking paints, these luminous glass microbeads significantly enhance the anti-reflective properties of road marking coatings, thereby bolstering night driving safety-a fact endorsed by transportation departments worldwide. During nighttime driving, headlights illuminate road markings embedded with these glass microbeads, causing the light to reflect back in a parallel manner. This reflection allows drivers to perceive the road direction with clarity, substantially elevating the safety of nocturnal journeys. As of now, reflective glass microbeads have achieved an indispensable status in the realm of road safety products.
