Classification, advantages and disadvantages of metal reflective film materials;
1, economic grade reflective film: (advertising grade, commercial grade)/license plate grade/maritime grade.
The reflective principle of this series of reflective films is the same as that of engineering grade.
2. Engineering-grade reflective film: The performance of this series of reflective films belongs to the standard JT-T279- 1995 issued by the Ministry of Communications of People's Republic of China (PRC), and it is a durable closed reflective film. Since the early 1950s, this material has been successfully used to make traffic signs. Objective in area where traffic flow is small and motor vehicles are drive at low speed, engineering-grade reflective films still have certain applications.
Engineering-grade reflective film is suitable for general road traffic signs, that is, common first-class, second-class, third-class and fourth-class roads and temporary use signs. Generally divided into two types: pressure-sensitive type and heat-sensitive type. Various patterns can be made by using the same ink and screen printing technology.
3. High-strength reflective film: The performance of this series of reflective films belongs to the second-class reflective film of the standard JT-T279- 1995 issued by the Ministry of Communications of People's Republic of China (PRC). High-strength reflective film is a durable sealed reflective film, and its brightness is at least three times that of engineering reflective film. This material has been successfully used to make traffic signs. Even if the sign is in a large angle and bright area, the high-intensity reflective film makes the sign clearly visible and effectively predicts the road danger in front of the driver.
High-strength reflective film is suitable for general road traffic signs, that is, ordinary highways, first-class, second-class, third-class and fourth-class roads and temporary use signs. Meida MD 1800 series is an acrylic mask, and 1500 series is a pet mask. There are two kinds of surface patterns: diamond and honeycomb.
4. Diamond-grade reflective film: The performance of this series of reflective films belongs to the first and second grade reflective films in People's Republic of China (PRC) and JT-T279- 1995 standard issued by the Ministry of Communications. Its reflective principle is different from the glass beads used in engineering-grade and high-strength reflective films, but it adopts the latest microcrystalline cubic reflection technology.
After each microcrystalline cube of diamond-grade reflective film is connected and arranged, there will be more than 930 microcrystalline cubes in a square centimeter of material area. The lower layer of the microcrystal cube corner is sealed to form an air layer, which makes the incident light form total internal reflection, thus achieving the best reflection effect without the help of a metal reflection layer. Compared with the traditional engineering-grade and high-strength reflective film, the diamond-grade reflective film made of wear-resistant and high-hardness polycarbonate material and microcrystalline cubic technology not only doubles the reflective performance, but also greatly improves the wide-angle performance. The brightness of diamond-grade reflective film is more than 6 times that of engineering grade and more than 3 times that of high-strength grade.
Reflective film is a new type of reflective material which is composed of reflective layer formed by glass beads and polymer materials such as PVC, PU, PET, acrylic and PC.
The main quality identification points of reflective film: film material, reflective coefficient of glass beads, bead distribution rate, dead bead rate, color uniformity, weather resistance, adhesive layer viscosity, etc.
Different from the materials and products we remember, the reflective film introduced to you today has many colors and specifications for your reference, and its corrosion resistance and later construction and installation operation are more humanized, which can be used in the transportation field. For example, the fluorescent reflective film can absorb the light of the surrounding environment and play a warning role, even without electricity or lights as support, it can show a certain brightness. So the above example is about the purchase information of reflective film in many aspects. Interested friends can refer to it.
