What Is The Level Of The Reflective Film?

The level of reflective film can be divided into diamond grade, crystal grade, super strength level, high strength level, super engineering level, engineering level and economic level. The reflective principle of the reflective film is the same as that of the engineering grade. The performance of this series of reflective film of engineering class reflective film belongs to the JT-T279-1995 standard fourth level reflective film issued by the Ministry of communications of People's Republic of China, and it is a kind of durable sealed reflective film. Since the early 1950s, the material has been successfully used to make traffic signs. At present, the engineering grade reflective film still has certain applications in areas with low traffic volume and low speed driving vehicles. The engineering grade reflective film is suitable for traffic signs of general roads, that is, the usual first, two, three, four and temporary signs. Generally, it is divided into two kinds: pressure sensitive type and thermosensitive type. All kinds of patterns can be produced by screen printing with the same kind of ink. Uses: guiding signs, prohibiting signs, warning signs and indicating signs, as well as signs for ordinary advertisements. Life span: usually 3~7 years, depending on the manufacturer. Some manufacturers only provide reflective film for 7 years, and the brightness retention value after 7 years is at least 50% of the initial brightness value. Some manufacturers provide 5 -, 7 - year reflective films. Mei Da reflective materials Co., Ltd. provides 5 years of PET, 5 year acrylic, 7 year acrylic 3 kinds of Engineering reflective film. Suitable floor: aluminum plate and steel plate. Operating temperature: generally required at 18 - 28 degrees centigrade. High strength reflective film this series of reflective film performance belongs to the People's Republic of China Ministry of communications JT-T279-1995 standard third level reflective film, high strength grade reflective film is a durable sealed reflective film, at least three times more bright than the engineering grade reflective film. The material has been successfully used to make traffic signs. Even if the sign is in a large angle and in the bright area, the high - strength reflective film makes the sign clear and can effectively predict the road danger ahead of the driver. The high strength reflective film is suitable for traffic signs on general roads, that is, the usual highway, level 1, two, three, four and temporary signs. Generally, it is divided into two kinds: pressure sensitive type and thermosensitive type. All kinds of patterns can be produced by screen printing with the same kind of ink. The MD1800 series is acrylic mask, and the 1500 series is PET mask. The surface figures are 2 kinds of rhomboid and honeycomb. Uses: guiding signs, prohibiting signs, warning signs and indicating signs, as well as signs for ordinary advertisements. Life span: generally 10 years. Under the normal use condition, the brightness retention value of this series of reflective films is at least 80% of the initial luminance value after 10 years. Suitable floor: aluminum plate and steel plate. Operating temperature: generally required at 18 - 28 degrees centigrade. The performance of this series of reflective films of diamond grade reflective film belongs to the first and second level reflective film issued by the Ministry of communications of People's Republic of China. Its reflective principle is different from the glass bead reflection principle used in the engineering and high strength reflective films, but the latest technology of the reflection of the microcrystalline cube. Each microcrystal cube of the diamond reflector film is connected, and there will be more than 930 microcrystal cube corners on the area of a square centimeter of material. The lower layer of microcrystalline cubic corner body is sealed to form an air layer, which makes the incident light form the internal full reflection, so the best anti light effect can be achieved without the use of the metal reflection layer. The diamond grade reflective film made of high hardness and high hardness polycarbonate and microcrystalline cube technology is compared with the traditional engineering grade and high intensity reflective film, and its reflective performance is not only multiplied, but also the wide-angle performance is also greatly improved. The brightness of the diamond reflective film is six times higher than that of the engineering grade, and it is more than three times that of the high-strength level. Traffic signs suitable for high-grade highways and urban roads. Under normal use condition, the brightness retention value after 10 years is at least 50% of the initial luminance value. All kinds of patterns can be produced by screen printing with the same kind of ink. Uses: guiding signs, prohibiting signs, warning signs and indicating signs, as well as signs for ordinary advertisements. Life span: generally 10 years. Under the normal use condition, the brightness retention value of this series of reflective films is at least 50% of the initial luminance value after 10 years. Suitable floor: aluminum plate and steel plate. Operating temperature: generally required at 18 - 28 degrees centigrade.
