Reflective paint can emit strong reflection, because it contains a large number of small reflective glass beads. The surface is very smooth surface of the glass beads, when light on these beads, can produce the strong reflection effect, which emit bright light. The reflective principle of reflective paint mainly include:
1. The reflection of light. When light to the surface of the reflective beads, part of the light reflected back to the light source directly, the immediate reflection phenomenon will have reflective effect. Reflective beads surface smoothness is higher, the more reflective effect. 2. Total internal reflection. After some light into the reflective beads, because of the difference of refractive index, total internal reflection is formed within the beads, then rebound out of the surface of beads, it also can produce reflective phenomenon. Total internal reflection, the more the more reflective effect.
3. The scattering. After some light into the reflective beads, can produce scattering within the beads, and then to rebound out of the surface of the beads in all directions, forming diffuse reflection phenomenon, it will also improve the effect of reflective. 4. Specular reflection. Part of the light will illuminate the reflective beads on the surface of the smooth side, and then according to the incident Angle is accurate reflection, like a mirror reflecting the surrounding scenery. The specular reflection effect is weak, the main decorative effect.
So, reflective paint can have such a strong visual result, because of its comprehensive utilization of the light reflection and refraction, scattering optical principle. With the improvement of production process, the quality of the reflective beads also more and more high, reflective effect is also more and more ideal, meet the needs of the people in different places. Reflective paint, as a kind of new functional paint, no doubt, to improve life convenience at the same time, also enrich the design technique of expression, is worth wide application and development.
