The performance of this series of reflective films belongs to the first and second JT-T279-1995 reflective film issued by the Ministry of communications in People's Republic of China. Its reflective principle is different from the glass bead reflection principle used in engineering and high-strength reflective films, but the latest technology of microcrystalline cube reflection.
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.
