Diamond grade reflective film: the latest technology of microcrystalline cube reflection is used. After each microcrystalline cube is connected and arranged, there will be more than 930 microcrystalline cube corners in a square centimeter of material area. The lower layer of microcrystalline cube corner is sealed to form an empty gas layer, so that the incident light forms internal total reflection, so the most superior reflective effect can be achieved without the help of metal reflective layer. The brightness of diamond grade reflective film is more than six times that of engineering grade and more than three times that of high-strength grade. It is suitable for traffic signs on high-grade highways and urban roads.
Engineering grade reflective film: generally divided into pressure-sensitive type and heat sensitive type. Using similar inks and screen printing technology, various patterns can be made. Traffic signs applicable to general roads, i.e. general class I, class II, class III and class IV roads and temporary signs. Operating temperature: generally 18 ℃ ~ 28 ℃.
High strength reflective film: it is a durable sealed reflective film, which is at least three times brighter than the engineering reflective film. The material has been successfully used to make traffic signs. Even if the sign is at a large angle and in bright areas, the high-strength reflective film can make the sign clearly visible and effectively warn the driver of the dangerous situation on the road ahead. Traffic signs applicable to general roads, i.e. general expressway, class I, class II, class III and class IV roads and temporary signs. Applicable base plate: aluminum plate and steel plate.
An important role of reflective film is to improve the surface performance of traffic signs, make them adapt to the traffic needs of all-weather conditions, and improve the road safety operation conditions. The service life of engineering grade reflective film is generally 3 ~ 7 years, and the front two degrees (0.2o / - 4 o) of white film is generally about 100cd / LX / m.
