The thin lines of the rear window of the car actually have such a function?
[China Glass Net] Have you seen the thin lines on the rear windshield of the car? Do you know what these thin lines do? When driving on the road, I believe that many careful riders will find that there are a very regular horizontal line on the rear window glass of many vehicles, or red or other colors.
Most people think that these lines are the effect of the film attached to the film, either for decoration or for sun protection... but there are not many people who really know the meaning of these thin lines.
In fact, these lines are not brought by the film, but they are already on the rear windshield, but they look more obvious after being attached to the film. These lines are actually resistance wires. When the rear windshield is fogged and frosted, the fog and frost are dissipated by heat, thus ensuring a clear rear view.
In winter, the temperature difference between the inside and outside of the car is generally relatively large, or in the rainy season, it is easy to condense a layer of frost or water vapor on the window of the car, so that the riders are sitting in the car. I can't see the scene outside the car, but we need to reverse the car or some of the driving process, knowing some things behind the car at any time.
At this time, the line on the rear windshield of the car plays a key role, but it needs to be used with the defrost button in the car, and the frost or water vapor on the window glass is melted and evaporated by the heating of the electric resistance wire. This way, when you look out from the rear glass of the car, you can see it very clearly.
The button is located next to the air conditioner and the inner loop button, and some owners do not know its function. According to a 4S person, among the owners he touched, the defrosting button was mistaken for a large number of external loop buttons, and most of them did not understand the lines on the rear windshield.
The defrosting button can only be pressed during fogging and defrosting, and must be used after the vehicle is started. Otherwise, it will consume electricity and is not good for the car battery. The resistance wire on the rear windshield should be used with the defrost button. Pay attention to the car wash or maintenance to avoid damage caused by scratches.
