Automotive films have become almost standard in automobiles, and the weather is getting hotter. Many car owners who are not yet filming are also considering applying thermal insulation films to their cars. However, the quality of the insulation film on the market is uneven, and the 4S shop selling and giving the film may not be suitable for every owner. In fact, to buy insulation film and buy a car, you need to look at the parameters, so that you can choose to meet their own needs and meet national standards. So what should be the focus of those parameters? Let people take you to find out.
First, the role of the film
Before looking at the parameters, let's talk about the role of the film. There are three main functions for applying the insulation film to the car:
1, blocking ultraviolet rays, sun protection
The insulation film achieves effective thermal insulation by reflecting infrared rays and ultraviolet rays, thereby reducing the temperature inside the vehicle. It can not only protect drivers and passengers in the car from exposure, but also can relieve the aging caused by exposure to leather seats and dashboards to some extent. In addition, according to everyone's understanding, most of the insulation films have a single-side light transmission feature, which can prevent glare caused by sunlight and reduce driving fatigue.
2, to ensure the privacy of the car space
Different color shades of the insulation film, for the owners who tend to protect the privacy of the car, the choice of dark color film will be more appropriate. However, according to the regulations of the Ministry of Transport, the transmittance of the front windshield and the glass on both sides of the driver should reach 70%, otherwise it cannot pass the annual review.
3, "explosion-proof" function
Some manufacturers will give the name “explosion-proof film†to the insulation film, but this is misleading. Most of the insulation films have no real explosion-proof function. At best, the glass is broken through the glue of its own adhesive layer. Splashing and hurting people in the car.
Second, the parameters of insulation film
Most car owners may not know that the insulation film is also a parameter, understand these parameters in order to buy their own insulation film, to avoid buying counterfeit film or film that does not meet the requirements of the State Department of Transportation. In the purchase of insulation film, everyone recommended the main reference to the following parameters:
1, infrared blocking rate (heat insulation rate)
In the spectrum of sunlight, infrared light carries most of the heat, and blocking infrared rays can block the high temperatures outside the vehicle. In general, the thermal insulation film uses reflective or infrared absorption to block the temperature from the sunlight. Generally, the high quality thermal insulation film has a thermal insulation rate of 40%-70%.
2. UV blocking rate
Although UV can play a role in sterilization, but excessive UV can cause melanin to precipitate formation of stains, and even burn the skin, so when we say that when the sun is generally refers to the prevention of excessive UV. The UV blocking rate of common insulation film is only 40%, and the quality of the insulation film uses a deep-injection UV absorber, making the UV blocking rate as high as 98%, and even some of the UV insulation barrier film can reach 99% %.
3, visible light transmittance
A good insulation film should be able to effectively filter infrared and ultraviolet rays, but it can not affect the visual field. Generally, the visible transmittance of the solar film is between 5% and 75%. The traffic safety regulations of the Ministry of Public Security expressly stipulate that the light transmittance of the front windshield shall not be less than 70%. Otherwise, it will not pass the inspection and affect the annual inspection of the vehicle or vehicle. . In addition, if the visible light transmittance is too low, the effect of unclear lines of sight in the black sky will occur, affecting driving safety.
4, visible light reflectance
The automotive film can reflect part of the heat while reflecting visible light, which is helpful for enhancing privacy and blocking the transmission of heat to the car. However, excessive visible light reflectance may cause light pollution. Therefore, the law stipulates that the visible light reflectance of automotive films should not exceed 10%.
