The visibility of road traffic signs refers to the visibility of the color. If it is easy to be discovered and seen, it has high visibility. In order to increase the visibility of traffic signs at night, glass beads are mixed into the paint or spread on the surface of the coating when drawing the marking paint, which can reflect the car lights back to the driver's eyes, thereby greatly improving the visibility of the marking paint.
Glass beads are colorless, transparent balls that have the functions of refraction, focusing and directional reflection of light. Its addition can improve the brightness and durability of the marking paint on the basis of improving visibility.
Requirements for glass beads
Glass beads should be colorless and transparent spheres that have the functions of refraction, focusing and directional reflection of light; the roundness should be high; there should be few impurities, the particles should be uniform, and there should not be too much glass powder. The road marking paint manufacturer introduced that the reflection of the marking paint comes from the glass beads pre-mixed in the paint and the glass beads spread on the surface of the coating. If the roundness and refractive index of the glass beads are high and the particle size distribution is reasonable, the reflective effect of the marking paint will be good. The particle size of the glass beads is matched in a certain proportion to ensure that the glass beads in the road marking paint coating adhere firmly. During use, glass beads of different sizes are exposed and fall off in turn as the road marking paint wears, so that the road marking paint can continue to reflect light.
Our road marking machines are divided into three types according to different coatings: hot melt marking machine, cold spray marking machine, and two-component marking machine to meet your different needs.
