1, Specification of Glass Beads for Road Marking
( EN1423 EN1424 BS6088A BS6088B, AASHTO I M247 etc...)
Usage: Glass Beads for Road Marking / Pavement Marking can improve visibility of the traffic markings and road signs and supply safer night driving conditions. When driving at night, the headlights light on the graticule of glass microsphere, the glass microsphere can make the light of car-light to reflect parallel, and make the driver distinguish the direction in order to improve driving safety. For glass microsphere of various gradations, when the top big sphere is worn, the appeared bottom small sphere can be used continuously.
There are two Grades: Grade A & Grade B and high refractive index Glass Beads available:
Grade A, used to be mixed with the paint prior to stripping the road. As the paint layers wear, the beads are exposed giving the enhanced visibility of road markings.
Grade B, used to be dropped on the freshly stripped paint surface on the road to give immediate enhanced visibility to night drivers. Grade B product is generally used.
Other usage glass beads
1, Glass bead for Metal Cleaning and Polishing
The glass microsphere made from sodium lime glass has good chemical stability, certain mechanical strength and hardness. Therefore, it is more superior to be used as abrasive material than to be used as other abrasive material.
2, Glass bead for deluxe photoetch decoration, filler and reinforcement.
It is used in chemical industry. It is used as filler and reinforcement of glass microsphere in production. Generally speaking, glass microsphere is widely used, with strong usability. New technological field will be developed constantly.
3, Coated Glass Microsphere
On the premises of producing common glass microsphere, the factory developed coating technology. The coated glass microsphere is
A new product of glass microsphere develoed in recent years, which is used for road graticule surface spreading. With the excellent charcteristics, the great majority of users have paid much attention to it.
Glass surface coating is not easy to be eroded. In the process of storage and usage, glass microsphere whose surface is easy to be moisture is in humid atmosphere, It leads to light scattering, and therefore influences the direct reflection.
