The thin line of the rear window glass of automobile has such function?

Fanyu www. glass. com. cn 2017-10-12 16:42:40
Have you seen the strips of string on the rear windshield of the car? Do you have any idea what these thin lines do? When driving on the road, I believe that a lot of careful friends will find that there is a very regular horizontal line in the rear window glass of many vehicles, or red or other color.
Most people would think that these lines are the result of a film taped to the car, either for decoration or for sunscreen ... But it's not a lot of people who really know the meaning of these thin lines.
In fact, these lines are not the car film from the tape, but the rear windshield on the original, just put the car after the film looks more obvious. These lines are actually resistance wire, when the rear windshield fog, frost, through the heat to make the mist and frost dispersed, thus ensuring clear rear view.
In winter, the temperature difference in car outside the car is generally relatively large, or in the rainy season, it is easy to condense a layer of frost or water vapor on your car windows so that the friends can not see outside the car in the car, but we are reversing or, in the course of some of the driving needs, Keep abreast of some of the things behind the car.
At this time, the car behind the windshield of the line has played a key role, but it needs to be used in conjunction with the car's defrosting key to use, through the resistance wire heating to make the window glass frosted or water vapor dissolved evaporation. So whenever you look out of the back of a car, you can see clearly.
The button is located in the air conditioner and the inner circulation button, some owners do not know its role. According to a 4S staff said in his contact among the owner, the Defrost button is mistaken for the outside circulation of the key, most people do not know what the line on the windshield.
Defrost keys can only be in the fog, defrost when pressed, and must be used in the vehicle after the start, otherwise it will power consumption, the car battery unfavorable. The rear windshield of the resistance wire to cooperate with defrosting key use, car washing or maintenance should also pay attention to avoid scratches caused damage.
