Reflective glass beads(retroreflective glass beads) are made of glass sand, after melting temperature the  formation of a tiny glass beads, was observed under the microscope spherical, colorless, transparent, refractive index  of 1.50-1.64 between the diameter is generally between 75 microns to 1400 microns Currently in the domestic  production of major road Reflective glass beads craft flame floating method. 

 

Reflective glass beads for road marking(paint) in the reflective material, can improve the retroreflective pavement  marking paint performance, improve night driving safety,  national transport sector has to be determined. When driving at night, the lights shone on road signs with glass beads online,  make parallel light rays and reflected back, allowing  the driver to see the way forward to improve the safety of driving at night. Now, reflective glass beads has become a road safety products, reflective material can not be replaced.

 

  Reflective glass bead for road, mainly used in normal temperature, hot melt road marking paint, a method for  premixed material can ensure marking period in the life of the long-term reflective; one kind of construction in the  marking surface spreading, can play an instant reflection effect.  coated glass beas are divided into two types, one as reflective highway A screen used as reflective. Coated glass beads is to use a high-performance organic materials on glass beads for external processing, making the glass bead surface adsorption air weakens the dust. as micro beads coated with a specific coupl-ing agent, to improve the  adhesion of the coating bead and to prevent deposition of micro beads to the paint. Because of its function floatability.  the use in the coating surface float, which has the largest surface area can be in creased more than 30% utilization.

  Glass bead coating processing performance is more superior. It rains more often foggy in humid environments, with  better reflective capabilities.
