Tell a joke, the darker the car glass film, the better the heat insulation effect?

Friends often ask about Che Jun, and I want to put a glass film on the car. What color should I paint it? Is the darker the color, the better the heat insulation effect? Listen, it's the same reason that I wear dark clothes to absorb heat ... I don't know why, whenever someone is so "reasonable" with me, I have an impulse to hug him.

Many people are asking, so Che Jun decided to use an article to solve the problem today. If someone asks later, they will throw him a link directly.

The heat insulation effect of automobile glass film has nothing to do with color depth, nothing, nothing! Say the important things three times!

Infrared rays and ultraviolet rays in light contain most heat, while visible light contains a little heat. So heat insulation is to block ultraviolet and infrared rays. The higher the barrier rate, the better the heat insulation effect. The color depth of the glass film is determined by adding pigments, which can not effectively block ultraviolet and infrared rays, but can only block visible light. Under the mature film-making process conditions, even the light-colored glass film can let visible light into the car, and at the same time leave ultraviolet and infrared rays outside the car independently and effectively.

Moreover, the country has requirements for the light transmittance of the front glass film, and the light transmittance must be above 70% to ensure driving safety, so the front glass must not be covered with a dark film. Can you put a very black film on that rear bumper? The answer is no, it is not recommended because there is no mandatory requirement in national laws and regulations, and there is no corresponding standard for reference. However, you can tear off the film during the annual inspection of the car or even when the traffic police find that your film is too dark on the road, which may affect the driving safety.

If you want to choose a really good thermal insulation film, you must honestly look at the parameters, such as transmittance, ultraviolet blocking rate, infrared blocking rate and total blocking rate. There is also to know what film it is and what brand it is. After all, the brand of the big factory is ringing, and the quality is still guaranteed. Finally, you can check, touch and touch the real thing. After the good film is torn off the plastic lining, there are no bubbles when it is reassembled, while the inferior film has bubbles. If you feel comfortable and the film is thick and smooth, it is also a good film!
