[China Glass Network] In China, most car owners will decorate their cars after purchasing a car. One of the essential items is the window film. In most cases, we are attached to the car window with the car's solar film, and most of them are given or bundled by the 4S shop when buying a new car. Some car owners will choose to purchase the film for decoration. If there is no damage, the window film will generally follow the entire life cycle of the vehicle, that is, most cars only buy the film once. but do you know? If the quality of the window film is not good, it is likely to threaten driving safety and threaten the health of the people inside the car. It’s no exaggeration to say that the window and the solar film are at stake with us, and this is by no means an alarmist. Do not believe? Then I look down.
The private cars around us are almost all attached to the film, but ask the owner "Do you know what brand of film you are?", "What is the light transmittance?", "How much is the UV blocking rate?", "Front light transmission What is the percentage of national standards?" Wait, it is estimated that not many people can answer. Therefore, in the case of filming, we need to start from the beginning.
First, what is the car solar film?
Automotive solar film refers to a film that is attached to the front and rear windshield, side window glass and skylight of a car. This film-like object is also called a heat-insulating film. The main function of the solar film is to block strong sunlight, part of the heat and ultraviolet rays, so as to optimize the driving view and improve the driving comfort.
Second, why do you want to film?
I believe everyone has some understanding of the film, why should the film? Many people replied: "The film window is transparent, and there is no privacy." "Other people's cars are posted, and of course my car should be attached." "The film can be insulated, not so dry." That's right, this represents the understanding of most of the owners of the film, let's talk about the details of why the window should be filmed.
Since the solar film is to resist the sun's rays, then we must "know ourselves and know each other", first of all to understand the composition of the sun. The sun mainly consists of three parts: visible light (44%), infrared (53%) and ultraviolet (3%).
Visible light: The light visible to the human eye in the sun's rays. Too much intense visible light can easily cause glare to the driver and affect driving safety. According to the national regulations, the visible light transmission rate of the front bump film of the automobile is greater than 70%, which is to ensure the visual field to avoid the safety hazard caused by too dark light.
Infrared: More than half of the large sunlight is our invisible infrared, which is the main source of heat. Although we can't see it, we can feel its temperature.
Ultraviolet: Although it only accounts for 3% of the sun, it is more harmful to cars and people. Ultraviolet light can easily cause aging of the car interior, and it can also make people's skin discolored, wrinkled, and even damage the skin health.
Just because the sun will have a certain impact on driving safety or human health, the role of the solar film is to "optimize" it, block most of the unfavorable light, and ensure beneficial visible light transmission, thus improving safety to a greater extent. And driving comfort. This is why our car to film <br> <br> a film role: thermal insulation
As mentioned above, more than half of the sun is infrared, which is precisely the main source of heat. Blocking infrared light means blocking most of the heat.
