Our company has been making traffic signs for more than 10 years, and many reflective films have been used. The market varieties are also quite miscellaneous. It is not easy to distinguish them. Many production companies do not understand the reflective films required by municipal engineering. As a result, some manufacturers can not pass the inspection of reflective plates, or the reflection coefficient is not enough, which affects the traffic safety and the service life of customers.
What kind of reflective film do you have? For the traffic facilities commonly used in the classification of reflective film, we have a general understanding. Reflective film is a kind of film with night reflection effect commonly used in traffic safety facilities products. The reflective film realizes its reflective effect function through the principle of physical inverse reflection.
1. Ordinary reflective film: engineering grade reflective film, which is mainly advertising grade film. Engineering grade advertising film and ordinary film are only divided into thickness, engineering film is slightly thicker, and other reflective index is the same. Engineering film is mainly used in non municipal engineering, mainly for the needs of enterprises, with its low price, reflective effect, and not very strict requirements for enterprises and environment Use. For example, our city's parking lots, shopping malls, underground garages, reflective signs, and other companies are mainly used sporadically. Because of its low price and wide range of use, this kind of film has been widely used for more than ten years.
2. Domestic high-strength film: this kind of reflective film is usually lens embedded glass bead structure, and its service life is about 10 years. The commonly used super engineering grade reflective film brand is Tongming tm7800 series, which is mainly applicable to municipal roads. Its reflective effect and durability are better than those of advertising film. Municipal road construction, gas, water and railway projects are more used.
3. 3M film: this kind of film is imported. The engineering grade and super high strength film are commonly used in expressways, high-grade highways, urban expressways, trunk roads, etc., with a service life of more than 10 years. Due to its good reflectance and durability, it is widely used on expressways in various provinces and cities, and is the main film for high-speed highways.
