Reflective materials are very common and widely used in our daily life. They play a warning role, so that we can realize 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 Xiaobian gives you a brief introduction to the principle of reflective materials and the characteristics of reflective materials that are easy for other materials, so that everyone can understand how reflective materials can benefit us.
Principle of reflective materials
Brief introduction of reflective principle of reflective film? The most direct use of reflective materials is to play a warning role, reduce or prevent the occurrence of danger. ? Many people will be curious, and they don't understand that the seemingly inconspicuous reflective material will reflect such eye-catching light when the light shines. The principle of enlightenment is not difficult, mainly because the process is rather complicated. Because the glass beads are 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 part is reflected after being disassembled, and then it is disassembled again and returned to the air and back to the front of the screen. When the light shines outside the spherical vertex, 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 and the incidence is different, the returned light is not parallel light, and the effect is equivalent to diffuse reflection, but the efficiency is much higher than diffuse reflection. Therefore, the effect is much better than that of a white cloth screen. ? Reflective materials have made great contributions to social security since they came out. With the development of national economy, the improvement of people's living standards and the enhancement of safety awareness, reflective materials will be more widely used in China market in the future.
characteristics of reflective material
reflective material is a high-tech product widely used in traffic safety equipment, uniforms, work clothes, film pasting, protective clothing and other fields. This reflective material is made by using the principle of regression reflection of glass beads with high refractive index and advanced technology of focusing and post-processing. It can reflect the distant direct light back to the light emitting place, and it has good retro-reflective optical performance in both day and night. Especially at night, it can have high visibility as during the day. 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 appearance of reflective materials successfully solved the problem of "seeing" and "being seen" driving at night.
Reflectivity: the reflective brightness of reflective materials is excellent. For example, the reflective intensity of silver-gray series products is 5CPL, and the reflective plastic film of white and fluorescent yellow is 7CPL, which provides the most effective and reliable personal safety guarantee at night or in poor sight. ?
wide angle: the reflective material is not only superior to similar products of other brands in terms of reflective effect, but also has wide angle, that is, it can still obtain good reflective effect when the light is incident at a great angle with the surface of the reflective material. ?
diversity: in order to match the characteristics and uses of other products, reflective materials are equipped with reflective cloth, reflective heat-sensitive laminating film, reflective letter pasting film, reflective lace, reflective plastic film, reflective ink, reflective yarn, reflective drawing film and SOLAS products, which have facilitated users' various choices. Flexibility and universality: Reflective materials can be used in a wide range of fields, such as safety vests and suspenders, work clothes, coats, rain gear, raincoats, sportswear, backpacks, gloves, shoes and hats, etc., and can also cut characters or screen print trademarks and patterns. In addition, the reflective film series can also be directly attached to leather or unexpected surfaces.
Above, Xiao Bian introduced the brief principle and characteristics of reflective materials. Reflective materials mainly use the principles of reflection and diffuse reflection to let light enter our eyes, which can warn people of obstacles or remind people of 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 uniforms and other fields.
