The tunnel is a kind of traffic facility to shorten the straight-line distance between two destinations, and most of the tunnel environment is not enough light, and it is necessary to use lights or a type of sign with a strong warning sign and paint to help the vehicle pay attention to safety during driving. One way to be more cost-effective, or must be used, is to use reflective paint. For example, we often call tunnel reflective paint, which can reflect light at night to help vehicles identify their direction in time and pay attention to safe driving.
Although I know what paint will be used, how to choose tunnel reflective paint? Are there any guiding criteria for making a choice? In other words, since tunnel reflective paint can be reflective, this reflection also needs to be measured. We can use the machine to test the reverse reflection coefficient to detect whether the reflection coefficient of the reflective paint is up to standard, if the reflective paint produced by the manufacturer has a reverse coefficient of more than 100, it means that the reflective coefficient of this paint is high and can meet the standard of safe reflection.
Because the tunnel is dark, the retroreflection coefficient value of tunnel reflective paint is as large as possible, and it is a good choice between 150-200. This value ensures that the reflection is normal and not too eye-catching.
