Product Description
Glass beads
During production of paints, qualified glass beads will be mixed into them as certain proportion required by standards.Certain proportion glass beads will be dropped on during application of paint on road, which has been mixed with glass beads, before they are dry. Under the effect of gravity of glass beads itself, the glass beads will inlaid into paint by part of their surface. When the car light attaches such kind of road marking lines, the light will be reflected back to the eyes of driver to increase driving safety at night.

Application
1. Road mark refractive index glass microsphere
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.
2. 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.
3. Military pneumatic shot blast
It is used for cleaning the turbine, blade and axle of the airplane engine.
4. It is used for deluxe photetch 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.
