Reflective material has now become a common material in life, constantly enriching our life. Reflective materials used for road marking have been very extensive. Premixed reverse materials in marking materials are used to broadcast anti reflective materials when marking construction. Reflective marking includes dry reflective marking and all-weather reflective marking. What is the design standard of the reflective material?
Linear contours: linear contours are used to outline the linear contour of the road, which is suitable for curved sections such as curved roads. Because of the roadside installation, the use of reflective film should adopt reflective material with a wide-angle performance.
A protuberance road sign: a protruding landmark is set up at the outside 10cm of the outer edge line of the lane to assist the marking of the outline of the lane. At the same time, by making the vehicle vibrate, it reminds the driver to leave the normal lane. The protuberant road sign is made of engineering plastic matrix, which ensures enough strength and firmness. The exterior surface of the protuberant is smooth and the shape ensures that the tire will not be damaged. The reflective element adopts the prism plate with isolated area and the color is white.
Speed feedback sign: the speed feedback sign is based on the radar speed measuring electronic equipment, installed in the speed and speed change area. Combine the speed limit signs and warning signs to remind the driver to control the speed of its formation.
The use of reflective materials will greatly improve the safety and provide an energy saving, environmental protection and safety guarantee. In the environment of continuous improvement of technology, reflective light, the use of reflective materials conditions, our products will achieve greater development.
The reflection principle of the reflective material is the reflection of the microprism. We all know that the reflection of light is diffuse and specular reflection, why can the light reflective material return back to original road. In fact, this is mainly due to the high refractive index glass beads. When a beam of light in a certain range at any angle onto the bead front surface, due to the high refraction bead bead in the spotlight after the surface of the reflective layer, the reflective layer along the direction of the incident light parallel light reflected back. The formation of reflection. When many glass beads and reflection, will appear in front of the bright scene.
Experiments show that when the refractive index of glass beads is close to 1.9, after the surface of incident light can be well focused on glass beads, the best regression reflection effect, when the refractive index is less than or greater than 1.9, the incident filled glass bead line respectively focusing on the outside and inside, then return the reflection effect the actual use will be reduced. Due to the influence of objective condition. The refractive index of glass beads usually in 1.9 - 2.1, and its diameter is usually less than 0.8 mm. If you add a layer of reflective layer behind the glass bead, then regression reflection effect is better. So magical micro glass the pearl is how to make it. The production process is this: first, the raw materials at very high temperatures, melting into molten glass, glass liquid through a special nozzle to form many droplets, these droplets in surface tension Under the action of 1, the rules are formed automatically, and after a certain amount of treatment, a very useful glass bead is obtained.
Using glass beads can be material for reflective material on the principle of making many regression reflective materials, such as light cloth, reflective paint, reflective ink and so on. Use of these materials in public security, traffic, fire, railway, coal mine and other departments, can see their shadow in the PPE and civil products
