Reflective traffic sign plates are professionally made with engineering-grade reflective film. Reflective traffic sign plates are mainly suitable for the production of traffic warning signs on various expressways, high-grade highways, and municipal roads.

How to distinguish the authenticity of reflective traffic sign plates?
How to judge the quality of reflective traffic sign plates?
As the application of reflective traffic sign plates on the market becomes more and more extensive, the quality of the reflective film of various reflective traffic sign plates is mixed, and it is possible to choose fake reflective traffic sign plates with a little carelessness. In this case, it is particularly important to choose a real product. We can distinguish the authenticity of reflective traffic sign plates through the following methods: 1. The genuine reflective traffic sign plates have a micro-prism structure, and the surface will have a rainbow effect when viewed at an angle of 45 degrees in the sun. If there is no such effect, it may be false. 2. Genuine reflective traffic sign plates are attached with watermark reflective labels at the factory. 3. The micro prism structure of the genuine reflective traffic sign plate and the surface film are permanently combined by a special process during the production process, and there will be no peeling off.
Reflective traffic sign plate is a retroreflective material that has been made into a film and can be directly applied, which is also seen everywhere in life. However, if we want to have high-quality reflective film products, we need to inspect all aspects of them to ensure their use. The common detection methods are as follows:
1. Test the acid and alkali resistance of the reflective film of the reflective traffic sign plate: the test of the acid and alkali resistance of the reflective film can be said to be a point that many people will overlook. We need to test in different acid, alkali, and solvents, and the resultant reflective film detection value should meet the national standard.
2. Check the brightness of the reflective film of the reflective traffic sign plate: we can observe from different incident angles and check the reflectivity of the reflective film of the reflective traffic sign plate to determine whether it meets the national standards. 3. Judging from the form of supply: the reflective film of the reflective traffic sign plates supplied in rolls should be uniform, flat, and tightly wound on a rigid round core, with neat edges, no deformation, no defects, and no extraneous inclusions. If these requirements are not met, it is unqualified.
The material and color uniformity of the reflective traffic sign film can be used to judge the quality of the reflective traffic sign. In addition to the above three methods, the easiest way is to check its quality from the appearance of reflective traffic sign plates. The surface of the reflective film of the reflective traffic sign plate should not have defects such as scratches, streaks, bubbles, uneven color, etc. The surface should be smooth, clean, and free of stains and debris.
