RETROREFLECTIVITY
Using beaded lines for nighttime refl ectivity is now accepted worldwide. The advantages of using refl ective beads are apparent when driving on a rural road at night. Added benefi ts of refl ective beads are to protect marking material from tracking and to improve durability. However, during the day, a non-beaded paint line will appear richer and a more uniform color. However, this is misleading because the non-beaded paint line may not be visible at night. If an engineer made the decision based only on the daylight evaluation, he/she would probably select the unbeaded line. If the same engineer evaluated these lines at night, he/she would undoubtedly select the beaded line. 2012 v1.0 2-3 Unbeaded paint lines will refl ect light randomly in all directions. When round refl ective beads are added, light is refl ected directly to the source of the light. In industry, this is called retrorefl ectivity. The following illustrations demonstrate this. Figure 2.3 Figure 2.4 Roadway with unbeaded markings Roadway with beaded markings In Figure 2.3 the light rays from an automobile`s headlights illuminate a surface that does not retrorefl ect. The light shining on the road, or a non-beaded line, is refl ected in all directions. Only a very small amount is refl ected directly back to the driver. The beaded line illustrated in Figure 2.4 produces a much greater quantity of light refl ecting directly back into the driver`s eyes. Therefore, the driver sees the line better.
reflective Coated Glass Beads have been treated with high quality organic materials on their surface, with high refractive index Glass Beads available. reflctive micro glass beads is used to making manufacture of reflective thermoplastic road marking paint. dropped on the freshly stripped paint surface on the road to give immediate enhanced visibility to night drivers.
Special coated glass microspheres glss beads, brighter and better in moisture proof. It is used by dropping , spraying after marking pant. The coating will increase durableness for glass microspheres beads and better function in rainy days and moist regions.
Glass microspheres / Glass beads are used as additives and intensifier for plastic, rubber, paint and composites. mainly used in the Pavement hot melt coating for the road marking lines and traffic signs. They characterized in equal size, smooth surface,clear ,transparent and round spheres, high hardness, chemical stability, etc with round rate more than 90% and highest purity.
