The base film of highway traffic signs generally uses super-strong reflective film. Compared with diamond-grade reflective film, super-strong reflective film is more affordable. At the same time, the service life of super-strong reflective film can also meet the use requirements of high-speed reflective film.
Prismatic reflective film is made by hot pressing, which first uses microprisms and substrates to press into reflective film, and then coats it with a layer of metal aluminum. However, when the hot pressed pyramids are affected by external factors such as extrusion, weather changes, and water washing, they are easily damaged and deformed, resulting in a significant decrease in reflective function, so this article introduces a new technology attempt.
The choice of traffic sign reflective film should be based on the surface scratches, whether the edge is deformed, whether the color is consistent, etc. In the process of film pasting, cleaning and washing products need to be paid attention to, or choose an excellent position to see whether the film is pasted correctly.
Prismatic reflective film is different from micro-bead reflective film. It is mainly used in signs and signs of some urban expressways, urban trunk roads, highways and other high-grade roads. Due to the needs of infrastructure construction, this product is widely demanded.
Microprismatic reflective film has multiple functions such as reflection, transmission, and diffusion. Because of its advantages such as long-term use without damage and high efficiency and energy saving, it is valued by many manufacturers and consumers. However, as the use time increases, the performance of microprismatic reflective film will gradually decline, and its lifespan has become a common concern.
The technical problem to be solved by the utility model is to provide a micro-prismatic reflective film that can improve the production yield of the product and effectively improve the reflective efficiency. The main representative products of micro-prismatic reflective films can be divided into four categories based on the retro-reflective characteristics and structure: truncated prisms that focus on long-distance recognition, truncated prisms that focus on close-range large-angle reading, full prisms that take into account both long-distance recognition performance and close-range reading performance, and new prism-type reflective films that combine these prism technologies with new material technologies.
Prismatic reflective film is a technology that improves optical performance through the principle of light refraction and reflection. Prismatic film corrects light through the refraction and reflection of light to improve brightness, uniformity and viewing angle. It is widely used in glasses, displays and other fields.
As a new type of optical film material, microprismatic optical film has important application prospects in road traffic safety. By improving the driver's visual perception ability, improving the safety of night driving and reducing the risk of driving in rainy days, microprismatic optical film can provide good protection for road traffic safety. In the future, through in-depth research on the preparation process and performance optimization of microprismatic optical film, its durability and applicability will be further improved to provide drivers with a safer and more reliable driving environment.
There are three different types of reflective film application areas, namely engineering grade, high-strength grade and diamond grade reflective film. There are differences and similarities between them, especially the application of microprisms, which is of great help to roads.
This passagemainly expect to introduce the prismatic reflective film that has great functions of refelction than other common films.What’s more,it informs us the application of this film and some conpaies that may need this film to do their basic products manufacture.
In relatively high temperatures, the reflective film should be stored in a ventilated, dry, cool environment, away from direct sunlight, avoid moisture, and pay attention to cleaning and ventilation, otherwise the performance of the three types of microprismatic reflective film may be reduced.
Traffic signs are widely used in highways and road construction, but the reflective signs for the corresponding scenes have different specifications.The variety levels of highways use different levels of reflective films to make signs according to the different design speeds. In addition,this passage tells us that how to paste traffic signs.
