Type III Glass Beads For Airport Road Marking
Description:
The high retro-reflective glass beads for airport road markings are optical grade glass beads. Different from ordinary road marking glass beads, the most significant feature of airport special glass beads is high retro-reflectivity, reaching 1.9-1.93, while ordinary road markings can only reach about 1.5. The high-reflectivity glass beads can reflect the light back to the light source more concentratedly, greatly increasing the visible distance of the reflection. The pilot can see the guideline more easily, which increases the safety of the aircraft during landing.
Features:
1. High reflectivity above 1.9.
2. High brightness. The retroreflective brightness coefficient is above 1000mcd/m2.
3. Energy saving. The glass beads are passive reflective materials and do not consume other energy.
4. The light reflected by the glass beads only reminds the pilot of the aircraft, and the other directions cannot be recognized.
5. Special surface treatment technology has good adhesion to all kinds of coatings and is not easy to fall off.
6. Good chemical stability, good mechanical properties and long service life.
7. Convenient construction, suitable for various marking paints and equipment.

TYPE III Glass beads for Airport Guide Line
The reliance of aircraft pilots on road markings is equivalent to the dependence of car drivers on road markings. Especially in an environment with bad weather or insufficient light, even if the pilots have navigation aid lights, they cannot clearly see the continuous road. As far as the pilots are often in a confusing environment and increase risks. If the road markings can be clearly seen at any time, it will definitely increase the pilot's responsiveness and improve safety.
