Different reflective film levels have different characteristics.
As part of the technology research and development will continue to advanced, reflective film with glass beads technology, micro prism technology, synthetic resin technology, thin film technology and coating technology and micro replication technology made has in our lives plays an important role. According to the type of reflective film adhesive, reflective film can be divided into thermosensitive reflective film, adhesive reflective film and reflective film without gum. The reflective film on the market can be classified according to the level of classification, and has different characteristics of different use, we have to carry out a one one finishing.
Diamond grade reflective film: the latest technology using the micro crystal cube reflection. After each crystallite cube is connected, there will be more than 930 cubic. After being sealed, the lower layer of the micro crystal cube corner forms an air layer, which causes the incident light to form an inner total reflection, so that the reflection layer can be achieved without the aid of a metal reflecting layer. The brightness of the diamond grade reflecting film is six times higher than that of the engineering level, and is more than three times of the high strength grade. Traffic sign for high grade highway and urban road.
Engineering grade reflective film: generally divided into two types: pressure sensitive type and thermal sensitive type. The use of other types of ink screen printing technology can make all kinds of patterns. Applicable to general road traffic signs, that is, usually the first, two, three, four road and temporary use of signs. Operating temperature: the general requirements of 18 degrees Celsius to 28 degrees celsius.
High strength grade reflective film: it is a durable sealed reflective film, at least three times more than the engineering grade reflective film. The material has been successfully used to make traffic signs. Even if the logo in a larger angle and light area, high strength grade reflective film can make the mark clearly visible, effectively to advance the driver in front of the road dangerous situation. Applicable to general road traffic signs, that is, the general highway, one, two, three, four and temporary use of the road signs. Applicable floor board: aluminum plate, steel plate.
An important role of reflective film is to improve the surface performance of traffic signs, so that it can meet the needs of all weather conditions, and improve the safety operation conditions of the road. The life of engineering grade reflective film is generally 3 to 7 years, and the white film is 100cd/lx/m (o 0.2o/-4).
