There are many grades of reflective materials. We can see reflective materials everywhere. The vests worn by sanitation workers are made of red reflective materials, the vests worn by public security policemen on highways are yellow reflective materials, and the vests worn by police uncles are blue reflective materials. Seeing these columns, we can know from the side the grade of reflective materials of vests with different colors, and his position is also different. Distinguishing the grade of reflective materials is one thing we need to know. Come on! Let's use our brains to distinguish!
Structure and color classification
It is composed of reflective layer, base film, pressure-sensitive adhesive and release layer. The main colors are white, red, blue, yellow, green, orange, fluorescent yellow and brown.
quality identification
the main quality identification points of reflective film are: film material, reflective coefficient of glass beads, bead distribution rate, dead bead rate, color uniformity, weather resistance, and viscosity of adhesive layer.
Reflective films are mainly used for guide card, signboards, mine and airport safety signs, stage scenery, trademarks, name plates, license plates, etc. of various highways and railways.
classification of grades
The grades of reflective films are classified into diamond grade, high strength grade, engineering grade and economic grade.
Engineering-grade reflective film
The performance of this series of reflective films belongs to the fourth grade reflective film of JT-T279-1995 standard issued by the Ministry of Communications of the People's Republic of China, and it is a durable enclosed reflective film. Since the early 195s, this material has been successfully used to make traffic signs. At present, in areas with small traffic flow and low speed of motor vehicles, engineering-grade reflective films still have certain applications.
the engineering-grade reflective film is suitable for traffic signs of general roads, that is, the common first-,second-,third-and fourth-grade roads and temporary signs. Generally divided into two types: pressure-sensitive type and heat-sensitive type. Various patterns can be made by using the same kind of ink and screen printing technology.
use: guiding signs; Prohibition signs, warning signs and indication signs, as well as signs used in ordinary advertisements. Life span: generally 3 ~ 7 years, depending on the manufacturer. Some manufacturers only provide reflective films for 7 years, and the brightness retention value after 7 years is at least 5% of the initial brightness value. Some manufacturers provide reflective films for 3 years, 5 years and 7 years.
applicable bottom plate: aluminum plate and steel plate.
operating temperature: 18℃ ~ 28℃ is generally required.
high-strength reflective film
The performance of this series of reflective films belongs to the third-grade reflective film of the standard JT-T279-1995 issued by the Ministry of Communications of the People's Republic of China. The high-strength reflective film 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 a bright area, the high-strength reflective film makes the sign clearly visible, effectively forecasting the road danger ahead of the driver.
High-strength reflective film is suitable for traffic signs of general roads, that is, common highways, first-class, second-class, third-class and fourth-class roads and temporary signs. Generally divided into two types: pressure-sensitive type and heat-sensitive type. Various patterns can be made by using the same kind of ink and screen printing technology.
use: guiding signs; Prohibition signs, warning signs and indication signs, as well as signs used in ordinary advertisements. Life span: generally, it is 1 years. Under normal use, the brightness retention value of this series of reflective films after 1 years is at least 8% of the initial brightness value. Applicable bottom plate: aluminum plate and steel plate.
operating temperature: 18℃ ~ 28℃ is generally required.
diamond-grade reflective film
The performance of this series of reflective films belongs to the first and second-grade reflective films in the standard JT-T279-1995 issued by the Ministry of Communications of the People's Republic of China. Its reflective principle is different from that of glass beads used in engineering-grade and high-strength reflective films, but the latest technology of microcrystalline cube reflection is used.
After each microcrystal cube of diamond-grade reflective film is connected and arranged, there will be more than 93 microcrystal cubes in a square centimeter of material area. The lower layer of the microcrystalline cube corner is sealed to form an air layer, which makes the incident light form total internal reflection, thus achieving the most superior reflection effect without the help of a metal reflection layer. Compared with traditional engineering-grade and high-strength reflective films, diamond-grade reflective films made of wear-resistant and high-hardness polycarbonate materials and microcrystalline cube technology have not only doubled their reflective performance, but also greatly improved their wide-angle performance. 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.
traffic signs applicable to high-grade highways and urban roads. Under normal use, the brightness retention value after 1 years is at least 5% of the initial brightness value. Various patterns can be made by using the same kind of ink and screen printing technology.
use: guiding signs; Prohibition signs, warning signs and indication signs, as well as signs used in ordinary advertisements. Life span: generally, it is 1 years. Under normal use, the brightness retention value of this series of reflective films after 1 years is at least 5% of the initial brightness value. Applicable bottom plate: aluminum plate and steel plate.
it is easy to distinguish the grade of reflective materials, and the quality of reflective materials with different colors is different. There are many colors, and the production of reflective materials is very complicated. It is different from the solid color clothes we usually wear, and it is more difficult to color. Reflective materials should also be particularly fine. There must be no slight pollution. A little pollution has caused an irreversible situation, so reflective materials have their own grades. Layers of model values can distinguish the grade of reflective materials!
