Today, with the rapid development of science and technology and transportation industry, the application of reflective materials has effectively improved the safety of roads at night, whether in expressways, ordinary sidewalks, roads or bridges.
At present, reflective materials mainly play an important role in the field of tooling and clothing, advertising and traffic safety, and have achieved good results. In the field of advertising, it can be used as road and Bridge billboard, site enclosure advertising, building construction frame advertising, light box, advertising label, body advertising, screen advertising, etc. In the field of road traffic safety products, reflective films are mainly used in: road signs, anti-collision cones, temporary construction signs, body reflective signs, etc. The advertisements made of reflective materials have good night visibility. Passing vehicles can clearly see the road outline and the figure of pedestrians, making it easier for drivers to distinguish obstacles from pedestrians at night.
Our common reflective vest worn by traffic police on duty uses the principle of high refractive index of reflective tape in reflective materials. The reflective vest is composed of bright reflective strips and fluorescent base cloth. The surface of the reflective tape is covered with glass beads. When a beam of light irradiates the surface of glass beads at any angle within a certain range, due to the principle of high refractive index of beads, the reflective layer returns the light to its light source along the incident direction, so as to play the role of safety warning; Fluorescent base fabric is very eye-catching, which makes the safety level of reflective vest a higher level. The use of reflective vest undoubtedly makes driving and roads have high safety, ensures the safety of drivers and pedestrians, and makes the traffic run more smoothly.
