The 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 guide line more easily, which increases the safety of the aircraft during landing.
Features:
High reflectivity above 1.9.
high brightness. The retroreflective brightness coefficient is above 1000mcd/m2.
Energy saving. The glass beads are passive reflective materials and do not consume other energy.
hidden. The light reflected by the glass beads only reminds the pilot of the aircraft, and the other directions cannot be recognized.
Special surface treatment technology has good adhesion to all kinds of coatings and is not easy to fall off.
Good chemical stability, good mechanical properties and long service life.
Convenient construction, suitable for various marking paints and equipment.
