Glass beads application：
1. Sandblasting, Metal cleaning and Polishing
The glass beads 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. Road marking
The glass beads is the main materials of road marking. Its high reflection index, high roundness make the good safety on the road.
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.
