Retroreflective coefficient of reflective film and reflective grade standard There are many types of reflective sheeting, and it is tough to distinguish them from each other. So, in daily life, we will provide the reflective sheeting according to the contracts or the requirements of customers. All these refer to the retroreflective coefficient of reflective film and the reflective grade standard. But what are they？ The retroreflective coefficient of reflective film refers to the coefficient of the light source that the reflective film can reflect back when the light hits the surface of the reflective film. The coefficient here is a specific value. The following will introduce the retroreflective coefficient standard of commonly used reflective film. This standard is the minimum requirement in the national standard "GB/T18833-2002" road traffic sign reflective film file. Compared with the new standard, the old national standard has four levels of reflective sheeting: 1. Class I type of reflective sheeting is also called engineering reflective sheeting.It can be written as I type reflective film. The retroreflective coefficient requirements for I type of engineering-grade reflective film are: When the observation angle is 0.2 and the incident angle is -4°, the minimum coefficient requirement for white is 70, yellow is 50;orange is 25,red is 14, green is 90,blue is 40,brown is 10,and gray is 42. 2. Class II type reflective sheeting is called super engineering reflective sheeting, which is the III type reflective sheeting in the old national standard. The retroreflective coefficient requirements for the II type of super engineering-grade reflective film are: When the observation angle is 0.2 and the incident angle is -4°,the minimum coefficient requirement for white is 140,yellow is 100,orange is 60,red is 30 ,blue is 10, brown is 5.  3. Class III type reflective sheeting is called super reflective sheeting. The retroreflective coefficient requirements for the III type of super reflective film are: When the observation angle is 0.2 and the incident angle is -4°,the minimum coefficient requirement for white is 250，yellow is 175， orange is 100， red is 50， green is 45，blue is 20， brown is 12, the fluorescent yellow green is 200, fluorescent yellow is 150, and fluorescent orange is 75. 4.

The fundamentals and applications of prismatic reflective sheeting Prismatic reflective sheeting belongs to the reflective sheeting. In contrast, it can be divided into two categories: glass bead type reflective film and prismatic type reflective film according to the classification of reflective sheeting. So now, we just comprehend some basic knowledge and applications of the prismatic reflective film. Prismatic reflective sheeting is a reflective material that is made based on the principle of refraction and total reflection of a cube. And every cubic cone’s surface degree of smoothness is over 5nm, and the angle error is less than 0.01 arc seconds. Besides, there are 10,000 prisms distributed in every square centimeter. Under this circumstances, we can say it a reflective product that combines ultra-precision technology and craftsmanship. Compared with the glass bead reflective film, it has great reflection effects, like great reflective function at long distances, and is easy to find. Because of these traits, it is widely used in highway traffic signs. Among the variety of reflective sheeting, the PC prismatic reflective film belongs to the national standard second-class reflective grade. Frankly speaking, its specifications are 1.22*45.7 meters, and the thickness is between 0.38 mm and 0.4 mm. There are many colors of it : white, blue, red, yellow, and so on. With these unique features, it is mainly used on highways, main urban roads, rural roads, etc. What are the functions of prismatic reflective sheeting? 1. Reducing the marginal cost From the perspective of running a company, it is not very realistic to install lighting tools on all roads. On the one hand, the plug-in project’s expenditure is large. On the other hand, it is different to check the problems with it at a later time. Therefore, people will take advantage of three kinds of prismatic reflective sheeting on many highways, which will reduce the cost because of their great reflection effects. 2. Enhancing the safety of the drivers when driving at night When driving on the roads, everyone expects a sense of security. Generally speaking, they want to go to the destination safely. So, whether the reflective traffic or the non-reflective ones, they all give a sense of security to the drivers. Because a lot of information is included in the traffic signs for the purpose of warning. For instance, the traffic signs will appear in the village, turning areas, and people will also raise awareness of dangers because of the signs. In that case, people will change the way they drive or their approach to driving according to the traffic signs so as to reduce the possibility of accidents. After we know its functions, the way of manufacturing will be explained next. How to make the prismatic reflective sheeting signs? From a professional perspective, reflective signs belong to the advertising industry, so users in need can find relevant advertising agencies to produce the products. However, the approaches to avoiding the possibility of fading is also crucial to the producers. Only when you know the scene it [...]

Unique advantages of prismatic reflective film As a new reflective material, prismatic reflective film has superior reflective performance and a wide range of applications. Its downstream customers are mainly public facilities, safety equipment, and high-grade highway construction units. At present, the prismatic reflective film used in the market is still dominated by well-known brands such as 3M, and the market share of domestic prismatic reflective film is relatively small. However, with the development and progress of microprismatic reflective film production technology, the quality of domestic brand reflective film products in the market is constantly improving, and gradually forming a certain competition with foreign brand reflective film. What is the role of reflective stickers? We often see colorful reflective stickers on different road traffic facilities, especially on road corrugated guardrails. This phenomenon is very common. The original intention of this arrangement is that most highways do not have street lights, resulting in dim light. In this environment, it is difficult for vehicles to clearly see the road conditions when driving, which makes accidents more likely to occur. In order to solve this problem, reflective films are attached to the ends of corrugated guardrails at intervals on highways. This practice can improve the reflective effect at night, emit special light reflections in the dark, and warn drivers to pay attention to the direction and distance of the road. Why is prismatic reflective film recommended? The microstructure geometry of prismatic reflective film in a non-planar state will change the effect on the reflective properties: the maximum effective bending angle of the curved reflective film decreases with the increase of the bending angle, with a decrease of 0.7%, and its value deviates less from the theoretical value; when the bending angle is greater than 20°, the reflectivity of the convex reflective film is 20% higher than that of the concave reflective film. In other words, prismatic reflective film is famous for its excellent retro-reflective performance and wide-angle visibility. It can maintain excellent reflective effect even in poor sign position and sight angle. In addition, the reflective film is waterproof, sun-proof and highly weather-resistant, so that it can stably exert its performance advantages under various weather conditions. It will not affect its service life due to erosion by the natural environment, thereby effectively reducing the waste of costs and resources. We use advanced technology and materials to make billboards shine like diamonds under light. Whether day or night, it can effectively attract the attention of passers-by and vehicles. By adding micro-prism reflective film to the guardrail columns, we have significantly improved nighttime driving safety and driving experience. Compared with installing flashing warning lights, this method is not only energy-saving and environmentally friendly, but also reduces costs and improves efficiency. On the highway at night, the reflective film shines brightly under the illumination of car lights, like rows of "highway guards", illuminating the road to safety for drivers and passengers.

In optical instrument systems , like total stations, we usually see the prism. So what is it ? What are its functions? 1. The introduction of the prism. It is prism that can be widely used in the variety of optical intruments ,which is ofen called reflective optics. 2. The functions of the prism: The main function of prism is to deflect or reflect the light path. After the total station emits a light signal, it then accepts the light signal reflected from the reflective prism. Next, we will calculate the phase shift of the signal. In this way, the time it takes for light to pass through can be indirectly calculated, and finally, the distance from the total station to the reflecting prism can be measured. 3 .The principle ofthe prism: In fact,the principle of prism is laws of reflection and refraction of light. To be more detailed, when light is reflected in the same medium, its reflection angle is equal to the incident angle. However ,when light is incident from one medium to another medium perpendicular to the planes of the two media, no refraction occurs. 4 .The classification of prims: Reflecting prisms can be divided into: single prism; 3 prism; 9 prism; simple prism; benchmark single prism, and etc. Some tips for you: 1. When using a reflecting prism, the prism constant is involved. Assuming that the vertex of the reflecting prism is on the vertical line of the measuring point, the correction value of the refractive index of the prism (glass material) is the prism constant. 2. The prism of the centering rod, we [...]

Some common facts or problems the reflective sheeting will encounter 1. When the reflective sheeting is over, it's the best time for usage. There may be many troubles when the reflective film is over the best time for usage. For instance, the reflective film surface will fade, have uneven brightness, or even fall off. If the reflective film used in the sign exceeds its service life, the information indicated will be unclear, and it will not be able to provide correct road information and ensure road safety, which may endanger safe driving. 2. The change of road information There are often some road rectifications, changes, or road name changes, which conflict with the original road signs (reflective film) content, so there is a need to replace the reflective film. How to select high-quality reflective sheeting? With the development of the reflective sheeting industry, more and more companies are joining this industry. So, there are many more factors to stimulate the update of products as well as the study concerning the technologies. In this situation, reflective film products are changing with each passing day. They have the characteristics of higher reflective brightness, stronger adhesive properties, or more convenient use, which better ensure road driving safety, and also promote the replacement of reflective film. When replacing the reflective sheeting, what preparations should we do? Taking road signs as an example, there are three steps: 1. Having a knowledge of the concrete applications and making decisions about what types of it you use. Reflective film will have different uses in scenes according to its concrete applications, so you have to pay attention to the selection of material for this purpose. Only when you do these things before will the reflective film have its best effects. 2. Measure the size of the reflective film required Before replacing the reflective film, it is advised to measure the size as well as the quantity of the sign aluminum plate. After that, you can place an order. 3. Determine the content and processing method of the sign Besides measuring the size of reflective film, you are supposed to decide the content in these road signs and the approaches to manufacturing. Common processing methods for reflective film include engraving, digital printing, screen printing, and inkjet printing. Application of engineering-grade reflective film in the field of security In the early 1980s, the reflective sheeting in China was used in the signage industry. With the development of the reflective sheeting industry, it has been widely used in the road traffic safety industry. This type of industry mainly utilizes reflective film as its major reflective material. As for the road traffic signs, the second type of super engineering-grade reflective film material has irreplaceable functional advantages. We can see the ultra-engineering grade reflective film in road traffic signs, various road traffic facilities such as raised road signs, contour signs, traffic cones, anti-skid cylinders, as well as car license plates, railway lines, etc. Meanwhile, as the 3M engineering grade reflective film occurs, [...]

What effect does reflective film have on cars? How to paste the car reflective film? Pasting requirement 1: After pasting the car body reflective logo, it should not affect the performance of the vehicle lighting and signal devices specified in this standard. Pasting requirement 2: No holes or grooves should be drilled in the car body's reflective logo. Pasting requirement 3: The pasted logo needs to be at least 380 mm above the ground. Pasting requirement 4: Before pasting, the dust on the surface to be pasted should be wiped clean. For areas with oil stains and stains, use a soft cloth dipped in a degreasing solvent or a cleaning agent to remove them, and paste them after drying. In addition, if the car body surface cannot be directly pasted with the car reflective film, the reflective film should be pasted on a strip liner with a certain rigidity, strength, and anti-aging, and then the strip liner should be firmly pasted or riveted to the body. Why do tow trucks need to be pasted with license plate reflective film? 1. Due to regulations. According to regulations, all trucks and trailers on the road must be pasted with reflective signs as required, and trucks and trailers with a total mass greater than 3.5 tons must be installed with side and rear protection devices as required. Violators will be warned or fined 200 yuan. The tow truck meets the standard of large trucks, so it is necessary to paste the license plate reflective film. 2. The necessary benefits of reflective film. It has been observed that traffic accidents are prone to occur when driving at night, and posting reflective film on the car can help avoid rear-end collisions. Imagine that at night, the vehicle is stationary, or it is anchored on the road. There is no obvious sign when the engine is turned off, and the lights cannot be used. This allows the car in the distance to see the outline of the car body clearly and avoid hitting it from the rear. In addition to the above two reasons, we must also consider the characteristics of the tow truck itself. For example, tow trucks are mainly used for emergency road rescue, and sometimes they have to go to work at night. When the tow truck is working at night, the reflective stickers on the body of the truck can play a good role in reminding drivers behind to avoid the tow truck from a long distance. How to identify counterfeit and inferior reflective body logos？ 1. Identify based on the reflective effect. The role of the body reflective logo is mainly reflected at night, so products that do not reflect at night or in a dark environment are counterfeit products. The identification method is: use a strong flashlight or a small flashlight to check at night or in a dark environment. The front of the body reflective logo faces the observer, the observation distance is 1m, the flashlight is close [...]

What should I pay attention to when purchasing reflective clothing? The use of reflective materials provides safety protection and warnings for various places, effectively reduces the risk of traffic accidents, and promotes safe relationships between vehicles and roads, and between vehicles. In addition, reflective materials are also widely used in professional clothing to ensure that workers can be conspicuously noticed when exposed to light during the day or at night to avoid accidents. The merits of reflective clothes: Reflective clothing is usually made of fluorescent colors, and the bright fluorescent color forms a strong contrast with the surrounding environment during the day, which can timely arouse the attention of other passing vehicle drivers. At night or when visibility is low, its 360-degree large-area reflection can quickly arouse the attention of drivers and bystanders from a long distance when illuminated by car lights, greatly reducing traffic accidents and facilitating search. The reflective part of the reflective clothing manufacturer is made by using the principle of refraction of the micro-diamond shape of the lattice and the retro-reflection of high-refractive glass beads, and the advanced process of focusing post-processing. It can reflect direct light from a distance back to the light source, and has good retro-reflective optical performance regardless of day or night. Especially at night, it can have the same high visibility as during the day. Safety clothing made of this high-visibility reflective material can be easily spotted by night drivers regardless of whether the wearer is far away or under the interference of light or scattered light. The emergence of reflective materials has successfully solved the problem of "seeing" and "being seen" when driving at night. Common reflective materials on the market mainly include the following: 1. Reflective film. By using coating, lamination, composite, and other technologies, high-refractive glass beads or microprisms are embedded in the surface of the material to create a functional composite material to reflect light and form a reflection phenomenon. This reflective film is widely used in reflective film, license plate reflective film, and other fields. 2. Reflective cloth. Reflective cloth is a material with reflective properties, which is often used to make various warning signs, safety reflective clothing, etc. According to the different reflective effects, reflective cloth can be divided into high-angle reflective cloth, low-angle reflective cloth, all-around reflective cloth, etc. 3. Reflective lattice. Reflective lattice is a material made of a micro-prism structure, which is unique in its high reflectivity and wide angle. It is widely used in the production of various signs, warning signs, etc. In addition, there are other reflective materials, such as reflective fabrics, reflective coatings, etc. What are the differences in reflective clothing? In the downstream market, an important application area of reflective materials is high-visibility warning clothing, and the main products are various reflective clothing items that we can see everywhere in our daily lives. There are many domestic companies specializing in reflective clothing. In addition to the differences in production processes and other aspects, an important difference between [...]

What should be paid attention to when using laser cutting reflective sheeting? Reflective film is a reflective sheeting material made by microprism technology, synthetic resin technology, thin film technology as well as other processes. According to the principle of retro-reflection of light, reflective film can reflect the light emitted by the light to illuminate the direction of the light and remind relevant personnel to find the distance of the object in front, which makes this knid of reflective film widely used in the variety of fields, such as,r oad traffic, mining areas, and water transportation. In addition, reflective sheeting is also utilized to make performance costumes, various graphic advertisements, as well as outdoor decoration scenes, which is one of the most common film materials people utilize on weekdays. 2. Prismatic reflective film Why does reflective film need to be cut? It is said that this reflective sheeting demands the cutting to be an unchangeable shape and the laser cutting is one of the most common approaches to do this deed. Although the reflective sheeting has the ability to reflect the light, the highly energy-intensive laser can still easily cut the reflective film. What’s more, the edges after cutting are smooth and beautiful, without the need for secondary processing. So that the advertising industry that chases the great processing effect will lay emphasis on that reflective film. When using a laser to cut reflective film, the following matters need to be noted: Material properties: There are many types of reflective film, such as Class I engineering-grade reflective film, Class III high-strength reflective film, Class V high-angle reflective film, etc. On top of that, these reflective films have a multi-layer structure (substrate, adhesive layer, reflective layer, etc.). Materials with different characteristics have different cutting parameters. We need to determine the specific material composition in advance to prepare for subsequent processing. Laser type: Because the wavelength of the CO2 laser matches the light absorption characteristics of reflective sheeting, reflective film is usually cut using a CO2 laser, and the equipment is usually a laser cutting machine. If it is a thinner reflective film, a marking machine can also be used for cutting. Laser parameters: According to the thickness and material properties of the reflective sheeting, adjust the laser power. Too high power may cause the cutting edge to melt or burn, while too low power may not be able to complete the cutting. Set the cutting speed reasonably. Too fast may lead to incomplete cutting, too slow may cause the heat-affected zone to expand and cause material deformation. Ventilation and exhaust: Laser cutting of reflective sheeting will produce smoke and potentially toxic gases. Ensure that the work area is well ventilated and use exhaust equipment to remove these gases in a timely manner. Laser cutting of reflective film demands comprehensive consideration of multiple factors,for instance, material properties, cutting parameters, and safety measures. With the purpose of tackling the troubles in advance, it is best to conduct appropriate tests before processing,which [...]

The ultimate guide to reflective film: principles, identification, and quality testing Brief introduction of reflective materials: Reflective materials are based on the principle of retroreflection. They can use the illumination of car lights and the reflection of light to "light up" the front, increase the distance at which the driver can find objects in front, and thus give the driver more time to take corresponding safety measures. How to distinguish the authenticity of reflective film for signs, since the reflective film is so significant？ The following content introduces the following: Method 1 The genuine reflective film has a micro-prism structure. When observing its surface at a 45-degree angle in the sun, there will be a rainbow effect. If there is no such effect, it may be fake. Method 2 Genuine reflective film is attached with a watermark reflective label when it leaves the factory. Hold a flashlight between the two eyes and parallel to the two eyes. The light source shines on the label. The eyes follow the light source, and the label will reflect a dazzling watermark. Method 3 The micro-prism structure of the genuine reflective film and the surface film are permanently combined together using a special process during the production process, and there will be no peeling or shedding. Why does reflective film use special technology? The reflective film used for road traffic signs is a high-tech product. The main function is to use the unique properties of the reflective material of the reflective film to reflect light in the direction of the light source. Reflective film is a novel reflective material formed by combining the reflective layer formed by glass beads with polymer materials such as PVC and PU using a special process. Reflective materials, also known as retro-reflective materials, retro-reflective materials, reflective materials are widely used in various road traffic safety facilities such as traffic signs and markings, raised road signs, contour signs, traffic cones, anti-collision barrels, as well as car license plates, clothing and shoes, fire protection, railways, water transportation, mining areas, etc. And can be divided into traffic sign reflective materials, road marking reflective materials, raised road signs, contour signs, reflective materials for clothing, etc. The realization of the retro-reflective function of light is achieved through various reflective materials with retro-reflective properties. Most of these reflective materials are not naturally formed in nature, but rely on human creativity and are new substances invented and synthesized. Retro-reflective technology brings together multiple disciplines and technologies such as optics, materials science, mathematics, and organic chemistry. How to test the quality of reflective film for signs? Method 1 Testing the acid and alkali resistance of the reflective film. Regarding the detection of the acid and alkali resistance of the reflective film, it can be said that many people will ignore it. We need to test it in different acid and alkali solvents, and the reflective film test values obtained should meet the standards specified in the national standard GB/TI8833-2002 "Reflective Film for Highway Traffic Signs". Method [...]

What is full prismatic reflective sheeting? The full prismatic reflective sheeting can be utilized in all grades of roads and city roads’ traffic material. In Western countries, it starts to replace the investment and consumption of sign lighting. When making road signs, considering the long-term investment benefits and safety benefits, full prismatic reflective film can replace any grade of reflective film. The main applications of full prismatic reflective sheeting: Full prismatic reflective film is mainly used in road signs, prohibition signs, warning signs, and instruction signs. In particular, it serves signs that require a long time to read or are in complex visual environments, and wide roads or high-grade highways, where its performance is particularly outstanding. The base plate for diamond-grade reflective film is an aluminum plate, and the processing temperature is generally required to be above 18 degrees Celsius. Comparison of retroreflective brightness values​of engineering-grade reflective film, high-intensity grade, truncated prism, and full prism at various angles: With the advancement of technologies, various angles of the full prismatic reflective film’s photometric performance have obviously improved. In recent years, prismatic reflective film without major changes in structure has shifted the focus of innovation to achieving richer light control effects and richer material properties through different material processing technologies in order to attain different retroreflective capabilities and different flexibility to meet the demands of different levels. On top of that, the reflective sheeting known as "super strong grade", "extra strong grade", and prismatic engineering grade (new super engineering grade) in the market are all new forms of prismatic reflective films. The truncated prism structure of these reflective films is basically the same, but the material processing technology is different, resulting in different reflective effects, superior weather resistance, and processing adaptability in order to meet different application requirements. Among these, super reflective sheeting that complies with the market demand has quickly become popular after it came out in the early 21st century. The original design theory is to take advantage of its structure. That is,making it have great reflection effects with different angles when we ensure all the basic functions of it. So, it will be cheaper and practical. These new prismatic reflective films have high intensity and thickness, which also erase the demerits, like tearing, wrinkling, bubbles, as well as surface honeycomb protrusions when produced. So that we can improve the manufacturing speed, and it will be easier to produce. That means we can control the production process more simply. At the same time,because of the large surface brightness factor of the reflective film, the retroreflective performance is greatly improved. It not only has a superior retroreflective coefficient at a long distance, but also can keep the sign at a good brightness at a large observation angle at a close distance under general visual recognition requirements, so that the drivers can find the sign earlier and read the content of the sign more clearly at a close distance. Different retroreflective effects can be formed through the differences in the material [...]
