Reflective vinyl film, is a film has been made directly applicable retroreflective material. Made using glass bead technology, micro prism technology, synthetic resin technology, thin film technology and coating technology and microreplication technology. Usually there are white, yellow, red, green, blue, brown, orange, fluorescent yellow, fluorescent orange, fluorescent yellow-green, foreign fluorescent red and fluorescent pink.

There are many classification methods for reflective film rolls. One of the more generally accepted classification principle is based on the basic structure of the retroreflective elements, according to the retro reflectivity of the retroreflective film front side of the retro reflectivity coefficient based ranking method. However, taking into account the different reflective film technology, some are specifically designed to solve the brightness of the non-positive retroreflection, and some are both performance, but also some of the requirements of the visual recognition of adverse weather conditions, so this classification method There are deficiencies. Therefore, it is necessary to be familiar with and master the application conditions and design functions of various reflective vinyl material.

In the traditional habit, according to the structure of the reflective film reflective unit, the reflective film is divided into two categories, a glass bead type reflective film and a micro prism type reflective film. Each type of reflective film also contains many types, such as micro-prism type reflective film, due to the use of more advanced technology, its material selection and prism structure, there are many changes that can cope with more traffic needs. According to the form and technical characteristics of the prism, the micro prism type reflective film can be further divided into a truncated type prism reflective film with good long-range retro reflectivity, a truncated-type prism reflective film with good high-angle retroreflection performance at short distance, All-prism retroreflective film, fluorescent full-prism retroreflective film that performs well during daytime and harsh climatic conditions, prismatic retroreflective film that conforms to conventional engineering-level retroreflective parameters, and the like. Glass bead reflective film appeared earlier, but the process changes are relatively small, there are two main types, one for the lens embedded reflective film, used to be known as engineering-grade reflective film; one for the sealed capsule type, usually called High-grade reflective film. In the lens embedded reflective film, due to its long history, various manufacturers, in the long process of manufacturing, the use of the lens diameter, density, thickness of the weather-resistant coating made a variety of reflective film, For example, super-engineering reflective film, mainly in the engineering-based reflective film, based on the use of higher quality glass beads, and the increased density of glass beads, in order to improve some brightness; commonly known as economic-grade reflective film, mainly in China Production is basically achieved by reducing the number and density of lenses (glass beads) on the basis of engineering-grade reflective film technology. Both of the reflective films and the economical reflective films cannot meet the traffic safety requirements, more is used in commercial areas, few in the world to be included in the standard of traffic safety standards.

In accordance with the type of adhesive, reflective film can be divided into heat-sensitive plastic reflective film, pressure sensitive adhesive reflective film and non-adhesive reflective film. The traditional reflective vinyl rolls used in transportation facilities is mainly pressure-sensitive adhesive. Pressure-sensitive adhesive, without heating, solvent or other preparatory work can be attached to a smooth, clean surface, traffic signs generally affixed to the aluminum or aluminum plate surface. The viscosity of the heat-sensitive adhesive is activated when the material is heated and pressure is applied. Gum-free reflective film, commonly used for self-supporting materials such as traffic cone reflective tapes, temporary roll-up warning signs and facility column reflective tapes.

Reflective film's primary role is to improve the surface properties of traffic signs so that they can adapt to all-weather traffic needs and improve road safety conditions. Due to different reflective properties of different types of reflective film, so in the concrete application of traffic signs made, you need to set the function and purpose of the logo, the corresponding norms. The science of studying this application specification has been regarded as an important part of traffic control and security technology by all the security engineering professionals in the world.

After the advent of engineering grade reflective film, was once mainly used for the production of signs, prohibition signs, warning signs and signs and signs used in ordinary advertising. With the progress of retroreflective technology and the continuous appearance of new materials, the brightness of engineering-grade reflective materials has gradually been considered as unable to meet the safety requirements. In developed areas, they are no longer being used to make warning signs and prohibited signs. It's hard to find any traces of large road signs and high-grade roads.

Engineering grade reflective film life is generally 3 to 7 years, the white film front two degrees (0.2 º / -4 º) is generally about 100cd / lx / m, according to different manufacturers. Some manufacturers only provide 7 years of reflective film, 7 years after the brightness retention value of at least 50% of the initial brightness value. Some manufacturers only provide 3 and 5 years of quality assurance. This is mainly caused by the different weathering of the reflective film, the same reflective material made of reflective film, the use of different regional climatic conditions, the length of their lives are different.

Engineering grade reflective film adhesive, generally divided into pressure-sensitive and heat-sensitive two, can be completed paste. Use the same type of ink using screen printing technology, you can also print a variety of patterns above. Engineering grade reflective film for the aluminum floor, the construction of the operating temperature is generally required at 18 degrees Celsius.

Lens sealing reflective film is a durable glass bead reflective film, the industry used to be called "high strength" reflective film, high strength reflective film is the use of glass bead reflective technology, because of its product structure innovation, with Reflective brightness and angle performance than engineering-grade reflective film, but at the same time, but also because of its own strong structure led to some insurmountable product defects such as brittle and easy to tear products, wrinkles, bubbles, surface honeycomb protrusions, High energy consumption, emissions and other large. The limitations of glass bead technology also hinder the high-intensity level to a higher brightness and better angle of improvement.

High-strength reflective film is also a material with a gum, generally divided into pressure-sensitive and thermal sensitive two. Using the same type of ink using screen printing technology can produce all kinds of patterns. High-strength reflective film is generally made of a resin film with good light transmission and weather resistance as the surface layer, the second layer is a vacuum layer, the third layer is embedded micro glass beads, the fourth layer is a metal reflective coating, the fifth layer is a resin Bearing layer, the sixth layer is adhesive, the seventh layer of paper protection layer.

High-grade reflective film is mainly used to produce the main signs of traffic signs such as road signs, prohibition signs, warning signs and signs. After the advent of high-strength reflective film, the driver reduced the time for identifying traffic signs and found that the distance between signs and obstacles in front was significantly advanced, greatly increasing the time for taking safety precautions, reducing the incidence of road accidents at night and improving the traffic safety Sex. According to empirical studies, the brightness of high-strength retroreflective materials is significantly higher than that of engineering-grade retroreflective materials.

High-quality high-quality reflective film is generally 10 years life expectancy, white film front brightness (0.2 º / -4 º) is generally 250cd / lx / m above, under normal use, the brightness retention after 10 years at least the initial brightness The value of 80%, high-strength reflective substrate for aluminum substrate, the operating temperature is usually required at 18 degrees Celsius.

Reflective construction

Reflective industrial materials mainly refer to the six levels of all kinds of reflective film, diamond-grade reflective film, super-reflective film, high-strength reflective film, reflective engineering film, advertising-grade reflective film and license plate reflective film. Mainly used in the production of a variety of reflective signage signs, vehicle number plates, safety equipment, etc., in the daytime with its vivid colors play a significant warning role in the light of night or lack of light, its bright reflective effect can effectively Enhance people's ability to recognize, see the target, arouse vigilance, thus avoiding accidents, reducing casualties, reducing economic losses, becoming an indispensable safety guard for road traffic, has obvious social benefits.
