Work Principle of Intermix Glass Beads
Intermix glass beads play a necessary part in traffic safety because of their retro-reflective properties. This property lets the motorist truly see the pavement line markings more significant at night and in moist conditions. When a car’s headlight beam shines on a pavement marking that is integrated-embedded-saturated with intermix glass beads, the line stripes light up and come to be plenty less complicated to see at night. This effect is called retro-reflection.
After the premix glass beads are rubbed repeatedly with the vehicle tires, the intermix glass beads on the surface will gradually wear out. At this time, the pre-mixed glass beads will be exposed, and then the reflection of the marking will be adequate.
How to Use Premix Glass Beads for Road Marking
In the road paint production process, the intermix glass beads are mixed into the paint according to the weight ratio of 18-25% (refer to the Chinese transportation industry standard JT/T280-2004, different national and regional have different standards).
