Reflective Heat Transfer Film Use the optical principle

Reflective heat transfer film is the production of traffic signs, license plates, signs, guide cards and other reflective signs and transport facilities necessary reflective material. This kind of reflective material uses the optical principle to reflect the light back to the light source to achieve the purpose of reflection, usually by good weather resistance film layer, micro glass beads layer, focusing layer, reflective layer, adhesive layer and peeling layer. Shandong road traffic development of Shandong reflective heat transfer film, reflective material production scale has been expanding. Shandong reflective coating products on the market according to the different performance can be divided into the following four: diamond-level reflective heat transfer film, high-grade reflective heat transfer film, engineering grade reflective heat transfer film, economic grade reflective heat transfer film. One of the economic grade reflective film is now more limited scope of application, the following highlights the first three reflective heat transfer film products.

       1, engineering grade reflective heat transfer film. This is a durable sealed reflective heat transfer film. Corresponding to the Ministry of Transportation issued JT-T279-1995 standard in the fourth level reflective heat transfer film. Since the early 1950s, this reflective material has been successfully used to produce traffic signs. At present, the traffic flow is small and low-speed motor vehicle driving area still has a certain application.

      2, high-grade reflective heat transfer film. High-grade reflective heat transfer film is a durable sealed reflective heat transfer film. Performance belongs to the Ministry of Transportation promulgated JT-T279-1995 standard in the third level reflective heat transfer film, is currently the most widely used reflective heat transfer film material. Even if the logo in a large angle and bright areas, high-intensity reflective heat transfer film makes the logo clearly visible, effectively inform the driver in front of the road dangerous situation.

       3, diamond-level reflective heat transfer film. The performance of this reflective material belongs to the Ministry of Communications issued by the JT-T279-1995 standard in the first and second level reflective heat transfer film, and its reflective principle is different from the engineering and high-strength reflective heat transfer film used glass Microbead reflection principle, but the use of microcrystalline cube reflection of the latest technology. The use of wear-resistant high hardness of polycarbonate materials and microcrystalline cube technology made of diamond-grade reflective heat transfer film with the traditional engineering and high-intensity reflective film compared to its reflective performance not only doubled, and wide-angle performance Also greatly improved. Its brightness for the engineering grade reflective heat transfer film more than six times, high-strength reflective heat transfer film more than three times.

  China's reflective material industry in recent years has made remarkable achievements, but the Chinese reflective material products are still blank areas, such as micro-prism-type reflective heat transfer film, high, refined, sharp reflective material products in the domestic number also Unsatisfactory. Reflective material production technology, research and development technology has yet to be further improved. In addition, the number of reflective materials, the number of enterprises is not a lot, many small manufacturers of independent research and development capacity is weak, poor business management capacity.
