Is it really necessary to shoot the front of the car?
1. It can insulate heat and isolate ultraviolet rays.
They think that car film can effectively insulate heat, thus reducing the heat in the car, which will not only make people feel comfortable, but also reduce the burden of air conditioning and save fuel when necessary. In addition, the car film can also block some ultraviolet rays and reduce their harm to the human body.
2. The glass will not splash after the front windshield is broken.
If a traffic accident causes the front windshield to break, if there is a car film, it can prevent the glass fragments from splashing and causing harm to people.
Mainly based on the above two reasons, they think that movies are necessary, but they ignore a problem. At present, the windshield of many models itself is heat-insulating and ultraviolet-proof. Moreover, it is only the front windshield, and the two side glasses and the rear windshield basically have no such function. If you don't believe me, you can try the money detector to see if it really protects against ultraviolet rays. Take the ocean of 100 and look through the car glass to see if you can show the invisible 100. If you can, it means that the car glass is not anti-ultraviolet, otherwise it is anti-ultraviolet.
In addition, there is a laminated layer in the middle of the front windshield for explosion protection. It turns out that at the beginning of windshield design, the designer has already thought about the problem of glass fragments splashing, so your worry is just superfluous.
In addition, according to national standards, the light transmittance of automobile front windshield shall not be less than 70%. The light transmittance of the front windshield of an ordinary car is about 75%, so the light transmittance of the front windshield window film should reach at least 90%, so that the light transmittance of the front windshield window film can exceed 70%, which is in line with national regulations.
However, at present, the qualified rate of the anterior barrier film on the market rarely reaches 90%. Even if there is, it is difficult to ensure that the transmittance can be completely controlled, because there is no vacuum gap between the film and the glass when pasting, and there are traces of adhesive on the film. Otherwise, it will affect the driving sight and cause safety hazards.
Finally, I will give you a popular science. In fact, the darker the color of the car film, the better the heat insulation effect.
