Road Marking Reflective Glass Beads with High Refractive Index
Description:
Road reflective glass bead is a kind of small glass bead formed by
melting glass sand (waste glass) at high temperature. It is
spherical, colorless and transparent when observed under a
microscope, with a refractive index of 1.50-1.64. The diameter is
generally between 75 microns and 1400 microns. So it is also called
reflective glass beads. At present, the main processes for
producing road reflective glass beads in China are flame float
method and electrothermal fusion method. As the reflective material
in the road marking (paint), road reflective glass beads can
improve the retroreflective performance of the road marking paint
and improve the safety of driving at night, which has been
determined by the transportation departments of various countries.
When the car is driving at night, the car lights shine on the road
marking line with glass beads, which can make the light of the car
lights reflect back in parallel, so that the driver can see the
forward direction clearly and improve the safety of driving at
night. Now, reflective glass beads have become an irreplaceable
reflective material in road safety products. Reflective glass beads
for roads are mainly used in normal temperature and hot-melt road
marking paints. One is used as a premixed material to ensure
long-term reflection of the markings during the life of the
marking; the other is spread on the surface during the construction
of the markings. Can play an instant reflective effect.
