Compared with ordinary light printing cloth, advertising 24 hours to achieve visibility. Reflective materials, has a unique built-in love of the light source or an external light source at night without reflective passing vehicles, the light emitted will be able to reach and built-in light source or an external light source visible. Use ordinary inkjet cloth advertising, advertising results only during the day only visible at night the visibility is very low, has no effect in the role of advertising. Reflective printing cloth during the day and ordinary printing cloth, but the night you can through the reflection of light emitted by passing vehicles, to achieve high strength, long-distance visible effect, so that advertising during the day and night with the same advertising effect. Because of these advantages, so the reflective printing cloth is a substitute for ordinary light box printing cloth. Advertising applications

From the shot to the light reflection in all directions to be much point, is the world, the reflective properties of reflective material, reflective performance is greater than 400CPL maximum reflective performance than 1000COL a reflective high weathering resistance, reflective angle excellent performance. The reflective material used in micro-prism reflection principle. You are aware that dynasty, the diffuse and specular reflection, why return to the reflective material can light upon the back track In fact, this is mainly due to the high refractive index glass beads containing a beam of light within a certain range any point of exposure to the front surface of beads, the beads of high refraction condenser in the beads after surface reflection layer, the layer of reflective light in parallel along the direction of light rays reflect back on the formation of retro-reflective when many glass reflective beads at the same time, it will appear in front of bright scenes. experiments show that when the refractive index close to 1.9 for glass beads, light rays can well gather to focus on the posterior surface of the glass beads, then the effect of retro-reflective best when the refractive index is less than or greater than 1.9, the incident charge line to focus on glass micro-special on the outside and internal, when the retro-reflective effect will be reduced. practical use due to the influence of objective conditions. glass microspheres the refractive index of the beads is usually between 1.9-2.1, and its diameter is typically less than 0.8 mm. If you add a layer of reflective layer behind the glass beads, retro-reflective effect will be greater so magical glass micro- beads produced the production process is like this: First the raw materials under very high temperatures melted into molten glass, molten glass through a special nozzle for the formation of many mist droplets, these droplets under the action of surface tension (1) automatic formation of the sphere of the rules, cooling and then after a certain treatment, you get a very useful glass beads, glass beads can create a lot of regression reflective material, such as light-emitting fabric, reflective paint, reflective inks, etc. use of these materials throughout the departments of public security, transportation, fire protection, railways, coal mines, their presence can be seen in the PPE and civilian products. drivers driving at night, due to opposite traffic lights, street lights, high-rise searchlight and advertising the impact of neon, likely to cause traffic accidents. bright light reflective material signs issued under the lights of the radiation is particularly striking, be able to remind the driver's attention to the relevant traffic information, to improve traffic safety. in rain, fog, wind and other low visibility weather conditions, reflective material to better highlight the value of so many developed countries, the provisions of road and rail traffic signs must use a reflective material, front and rear, the International Agency for marine life-saving also provides life-saving equipment must be equipped with reflective material to facilitate night search and rescue work. Here is not difficult to understand why the traffic police, firefighters and other wear with reflective material of uniform reflective tape on clothing or reflectors can effectively alert the driver drive carefully to improve the wearer's personal safety. Many companies are now using reflective materials to decorate their own products, on the basis of aesthetic and practical, but also increased security features. this magical reflective material to bring a lot of convenience to our production and living and he still has a lot of useless waiting for each one of us love science, hard thinking to develop.

The subject of reflective vest is mesh cloth or woven fabric, and reflective material is reflective lattice or high brightness reflective cloth.

The localization of the reflective material is the three aspects of the raw materials, equipment, process technology. Reflective material used in the main raw materials, including resin, pigments, glass beads, the performance impact of any raw materials of reflective products are essential. Among them, the bonding resin must have good workability, excellent bonding capacity, if the surface is not the product of the protective layer on the adhesive resin also requires water, wash the surface resin requirements of transparency, the ideal refractive index, excellent weather resistance and stability of the layers of resin then must also have a very good match, so in order to meet the optical properties of the product of reflective material requirements, use requirements and manufacturing process requirements; pigments, requiring high transparency , hue, stability, good and resin compatibility, glass beads, and requires a high refractive index, high transparency, low-loss-through rate, good roundness, good consistency of particle size and dispersion. National new materials, development of research in recent years stepped up efforts to support an endless stream of new materials, as well as the entry of large foreign chemical companies factories, the raw material of the reflective material required basically been solved. The production equipment is reflective material industrial base, the selection of equipment of different reflective material products, according to the product process, the process requirements, as well as the characteristics of the raw materials used, select the appropriate device configuration accuracy, mode of operation determine a reasonable device structure. Taking into account the minimum equipment investment in the production of technical requirements are met to do. Currently, the country nearly 10 years of development, the output capacity of the equipment has improved, but the design capacity of the equipment are still dependent on the manufacturer of the reflective material, Berry's early development of the company's equipment tracking, and many manufacturers imitate, as reflective The material equipment at home and laid a foundation. Various processes of basic configuration of the existing reflective material dedicated equipment is reasonable, most of the computer closed-loop feedback, variable frequency synchronous operation control, constant tension control, sub-regional adjustable temperature control, variable frequency constant pressure and other technical means, equipment operation and stability, coating drying ability, quality control is more stable, but the degree of automation equipment to be further enhanced. Production process and raw materials, production equipment, complementary, inseparable from the sulfur given the design of raw materials, to consider whether to meet the requirements of the production process, and determine the production process, it should be possible, does not change the raw materials to seek can be implemented is the easiest, most reliable way to process the production line according to different production processes, using a variety of coating methods, making different kinds and properties of coatings can achieve micron-level precision of the controlled coating, can guarantee full format of the coating uniformity. Sik Chu process and resolve on the device through a unique design, good maneuverability, easy and practical to solve the technical problems of a single layer of glass micro-glass beads total surface implanted. The technological level of domestic products has basically reached the level of foreign products, some products even better than foreign products, production processes more streamlined. China's standard two to five reflective material, ie glass beads through the habitat type of reflective material in the production of domestic, has formed a complete industrial chain, but in a reflective film micro-prism reflective film only 3M, Avery several reflective material to hold the related core technologies, our country just entering the development phase of this project, and the production of such micro-prism reflective material can be produced for civil and less demanding traffic uses reflective lattice films, product manufacturers are generally smaller, and do not have the capital and ability to master the core technology.

Over the past decade, a rapid development with the rise of China's basic industries, the reflective material in China's rapid development, have independent intellectual property rights in the area of a number of reflective material, a variety of reflective material products self-contained, not only alternative imported products, and have to go abroad in a number of product areas have begun to destabilize and abroad reflective material pioneer, began to seize their market share. Reflective materials industry in China in recent years have indeed made remarkable achievements, but within the field of reflective material, there is still a blank entry, such as micro-prismatic reflective sheeting, high, precise, sharp reflective material products in the domestic quantity not make were satisfied. Reflective materials, production technology, R & D technology has yet to be further enhanced. Other reflective material enterprise numbers of the scale are not many, many small manufacturers, independent research and development capacity is weak, poor business management skills. Reflective material of the future market development will inevitably require increasingly strong technical force, and further improve product quality, costs decline further, which has a higher demand on the enterprise of the reflective material.
