Wear Resisting High Hardness Sandblasting Glass Geads
Applications:
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.
