The principle of reflective material reflective

From the reflection of the light from all directions back to the source point, is the worlds highest performance reflective reflective material, reflective performance than 400CPL reflective properties than 1000COL highly reflective, weather resistance, excellent angle reflective performance.

The reflective material is micro-prism reflection principle. We all know dynasty reflection diffuse and specular reflection, why return to the reflective material can light the original way back then. In fact, this is mainly due to the high refractive index glass beads containing. When a beam of light at any angle within a certain range when the front surface of the irradiated onto the beads, the beads of high refractive and converging in the rear surface reflection layer on the beads, the reflective layer of the light along the direction of the incident light parallel to the reflection back to form retroreflective. When many glass beads while reflecting the show, there will be bright scene.

Experiments show that, when the refractive index of the glass beads close to 1.9 hours, the incident light ray can be well focused on the rear surface of the glass beads, the when the retroreflective best results, when the refractive index to be less than or greater than 1.9, is incident on the filling line focus in the glass microspheres special outside and internal, respectively, when the retro-reflective effect will be reduced. In actual use, due to the influence of the objective conditions of the refractive index of the glass beads is usually between 1.9-2.1, and its diameter is typically less than 0.8 mm, add a reflective layer behind the glass beads, then the retroreflective The effect will be greater.

So magical glass beads is how to produce it? The production process is like this: first raw material is melted into the molten glass at very high temperature, the molten glass through a special nozzle and forming a plurality of mist droplets, these droplets form a regular spherical automatically under the action of surface tension, after cooling and then after a certain processing on the obtained very useful glass beads.

With glass beads can be made many regression reflective material, such as reflective fabric, reflective paint, reflective ink. The use of these materials throughout the department of public security, transportation, fire protection, railways, coal, one can see their shadow in PPE and civil products.

Driver driving at night, due to the impact of the oncoming vehicle lights, street lights, high-rise searchlights and advertising neon, likely to cause traffic accidents. The reflective material signs a bright light lamp irradiation is particularly eye-catching, relevant traffic information to alert the driver to improve traffic safety. In rain, fog, wind and other low visibility weather, reflective materials to better highlight its value. Therefore, many developed countries provide road and rail traffic signs, front and rear of the vehicle must use reflective materials, international marine rescue agencies require life-saving equipment must be equipped with reflective material to facilitate night search and rescue work.

Here we can understand why the traffic police, firefighters and other wear uniforms with reflective material. These clothes on the reflective tape or reflective signs to alert the driver to drive carefully, to improve the wearers personal safety. Many companies are now using reflective materials to decorate their products, make it on the basis of aesthetic and practical, but also increased security features.

Magic reflective material to our production and life bring a lot of convenience, there are more available at waiting for a love of science, to develop the use of hard thinking.
