The necessity of reflective film for traffic signs
In the field of traffic facility manufacturing, reflective film plays a vital role. Whether it is signs, vehicle license plates or safety facilities, they are inseparable from the application of this special material. During the day, they remind passers-by to pay attention to safety with bright colors; at night or in low-light environments, these reflective signs can significantly enhance people's recognition ability through their unique reflective properties, making the target clearly visible, thereby improving vigilance, reducing the occurrence of traffic accidents, protecting personnel safety, and reducing economic losses. It has become an indispensable safety guardian in road traffic and has significant social benefits.
Common classification of reflective film
The reflective film used for highway traffic signs is a high-tech product. At present, the market is mainly divided into three categories: diamond grade, high-strength grade and engineering grade. This reflective film is made by a special process, combining microbead units with metal coatings with polymer materials to form a reflective material with good sealing and excellent weather resistance. It is widely used in various types of road traffic signs, including highways, primary, secondary, tertiary, and quaternary roads, as well as temporary signs, and can generally be divided into two types: pressure-sensitive and thermal-sensitive. Through screen printing technology, various patterns can be easily produced using the same type of ink.
There are many types of reflective film on the market now, including internationally renowned brands such as 3M reflective film produced by 3M Company of the United States, as well as Sino-Japanese joint ventures such as Enshiai reflective film and LG reflective film of South Korea. At the same time, there are also some reliable suppliers in China, such as Tongming reflective film and Hefei Bairuide reflective film, which all provide a variety of product options. Next, we will explore the various properties of reflective film.
1. The reflective film has the function of light reflection, so that the driver can clearly identify traffic signs when driving at high speed.
2. The paint film has a smooth surface, excellent anti-oxidation and anti-ultraviolet ability, and excellent weather resistance.
3. The reflective film is resistant to acid and alkali, resistant to atmospheric fog, and has good temperature and water resistance, ensuring a service life of more than five years.
4. Its strong adhesion makes the reflective film firmly adhered to road signs made of various materials such as wood, steel, and aluminum alloy, which is durable and not easy to peel off.
5. The product is non-toxic and harmless, does not contain radioactive substances, is friendly to people and the environment, and has no pollution.
6. The paint film can be cured at room temperature. The single-component design is convenient for cold construction and dries quickly.
Detailed process of film pasting for traffic signs
First, lay out on the aluminum alloy base plate to determine the position and size of the film. Then, cut the reflective film according to the results of the layout and engrave it. Then, attach the engraved reflective film to the traffic sign to complete the film pasting process. Finally, after a series of grinding, cleaning and drying processes, the traffic sign is completed.
1. Carefully select the appropriate reflective film according to the guidance of the design drawings. Before officially attaching the reflective film to the sign, be sure to check the model, color and grade of the reflective film to ensure the correct selection. At the same time, it is necessary to pay attention to the characteristic that the reflective film is easy to absorb dust due to static electricity, so it is necessary to operate in a clean environment to ensure the quality of the film.
2. When laying out the sign, try to make the reflective film fit the overall design. If bubbles appear accidentally, they need to be punctured and flattened again in time. Be extremely cautious during operation to ensure that the reflective film is installed correctly to avoid tearing caused by improper operation, which will affect its performance.
3. When pasting the layout information, the fonts should be pasted separately to ensure that reflective films of different grades or the same color are not mistakenly pasted on the same layout.
4. Since the surface of the reflective film is relatively fragile, special care should be taken during the cutting process to avoid damaging its reflective performance. At the same time, when pasting the reflective film, ensure that the layout of the sign is neat to avoid dust and other impurities affecting the reflective effect and service life of the reflective film.
5. In order to protect the layout information of the finished sign from dust pollution, it is recommended to wrap it with plastic film.
5. To ensure that the layout information of the finished sign is protected from dust, it is recommended to use plastic film to wrap it tightly.
