We often see markings on the road, but you know what? The reason why the marking line can be seen at night is because it has a reflective effect, and the reflective effect depends on the quality of the glass beads, and its refractive index, particle size selection, sedimentation control and other factors will directly determine the reflective effect.
How to choose logo glass beads? This is related to the road marking engineering requirements and actual conditions.
1. Choose from the aspect of appearance
Do not choose gray, dark and other opaque glass beads, but choose white, clear color and marking glass beads with less impurities.
Because the more transparent the glass beads, the better the light refraction effect, and the driver can clearly see the reflection of the marking line when driving.
2. Choose from the rounding rate of glass beads
From the production process of glass beads, the rounding rate of molded glass beads is about 80%-85%. If you want to have good night reflection performance, you need a higher rounding rate of glass beads.
3. Choose from the refractive index of the marking glass beads
Glass beads can be classified into low refractive index, medium refractive index and high refractive index. The higher the index of refraction of the marking glass beads, the better the reflective effect.
The standard of 1.50 is the refractive index of glass beads commonly used in Chinese road markings
4. Choose from the particle size of the marking glass beads
The choice of particle size should refer to different road marking construction requirements. Generally, it is recommended to use 30-50 mesh glass beads for two-component signs, which can control the settlement during construction and make the reflection effect more continuous.
