Reflective materials are very common in our daily life and are widely used. They play a warning role, make us aware of the danger in time and greatly reduce the probability of accidents. Reflective materials are used in many places, so what is the principle of reflective materials? What are the characteristics of reflective materials? Now, Bian Xiao will briefly introduce the principle of reflective materials and the characteristics that reflective materials are easily absorbed by other materials, so that everyone can understand how reflective materials benefit us.

Principle of reflective material

Brief introduction of reflective principle of reflective film? The most direct use of reflective materials is to play a warning role and reduce or prevent the occurrence of danger. ? Many people will be curious and don't understand that seemingly inconspicuous reflective materials will reflect such dazzling light when illuminated by light. The principle of enlightenment is not difficult, mainly because the process is complicated. Because the glass bead is spherical, because the light projected on the screen is similar to parallel light, when it hits the spherical vertex, the incident angle is very small, some light is reflected, the other light is decomposed and reflected, and then it is decomposed back into the air and back to the front of the screen. When the light shines outside the vertex of the spherical surface, the incident angle is very large, and the light will be reflected on the glass beads, and some light will be reflected on other glass beads, and then reflected back. Because the glass beads are round, the incidence is different, and the returned light is not parallel light, the effect is equivalent to diffuse reflection, but the efficiency is much higher than diffuse reflection. So the effect is much better than a white cloth screen. ? Since the advent of reflective materials, it has made great contributions to social security. With the development of national economy, the improvement of people's living standards and the enhancement of safety awareness, reflective materials will be more and more widely used in China market.

Characteristics of reflective materials

Reflective material is a high-tech product, which is widely used in traffic safety equipment, uniforms, work clothes, film pasting, protective clothing and other fields. This kind of reflective material is made by using the regression reflection principle of high refractive index glass beads and advanced focusing and post-processing technology. It can reflect distant direct light back to the place where it shines, and it has good retro-reflective optical performance no matter day or night. Especially at night, it can have high visibility as during the day. The safety clothing made of this high-visibility reflective material can be easily found by drivers at night, whether the wearer is far away or under the interference of light or scattered light. The emergence of reflective materials has successfully solved the problems of "seeing" and "being seen" when driving at night.

Reflectivity: Reflective materials have excellent reflective brightness. For example, the reflective intensity of silver-gray series products is 500CPL, and the reflective plastic film of white and fluorescent yellow is 700CPL, which provides the most effective and reliable personal safety guarantee at night or in the case of poor sight. ?

Wide angle: Reflective materials are not only superior to similar products of other brands in terms of reflective effect, but also have a wide angle, that is, when light is incident at a large angle with the surface of reflective materials, good reflective effect can still be obtained. ?

Diversity: Reflective materials are equipped with reflective cloth, reflective thermosensitive laminating film, reflective letter laminating film, reflective decorative tape, reflective plastic film, reflective ink, reflective yarn, reflective wire drawing film and SOLAS products, which are convenient for users to choose.

Flexibility and versatility: reflective materials are widely used, such as safety vests and suspenders, work clothes, coats, rain gear, raincoats, sportswear, backpacks, gloves, shoes and hats, etc. , you can also cut text or screen print trademarks and patterns. In addition, the reflective film series can also be directly attached to leather or unexpected surfaces.

Above, Bian Xiao briefly introduced the principle and characteristics of reflective materials. Reflective materials mainly use the principle of reflection and diffuse reflection to let light enter our eyes, which can warn people of obstacles or dangers ahead, such as fences or various traffic signs, and provide security for many vehicles to drive at night. In addition to transportation, reflective materials are also used in various fields such as uniforms.
