The use of reflective material market is more and more extensive, reflective material can at night or in low light situations, the light can reach the reflective effect, effectively enhance the people's ability to identify, see the target, causing alarm materials, mainly composed of reflective fabric, reflective film, reflective printing cloth etc..
Analysis of the working principle of the reflective material:
According to the principle of retroreflective, it can illuminate the front and improve the distance between the driver and the object in front of the car by using the illumination of the car lamp and the reflection of the light, so that the driver can take more appropriate time to take corresponding safety measures. Antireflection technology brings together a variety of disciplines and techniques, such as optics, material science, mathematics, organic chemistry and so on. Therefore, the reflective material is a product of a new technology, which improves our quality of life.
The reflective material for application of traffic signs, road traffic safety facilities, vehicle identification, indicator has been very extensive, to avoid accidents, reduce casualties, reduce economic losses the effect of reflection, the prospects for the development of the production principle of reflective material in the industry will be a good.
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 the principle of effective material on fruit reflection reflective material is better so magic glass beads is how to make it. The production process is as follows: the raw materials at very high temperatures, melting into molten glass, glass liquid through a special nozzle to form many mist liquid These droplets automatically form regular spheres under the action of surface tension. After cooling, a very useful glass bead can be obtained after a certain treatment.
Using glass beads can make 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, who can see their shadow in the PPE and civil products
