Can you put two layers of car film The most important thing about car film

Basically, there will be no two layers.

Applying two layers of film usually has two problems:

1) The adhesive design of the film is designed for glass, and it cannot ensure that the two layers of film are well pasted;

2) There is a certain difficulty in construction, the second layer of film may immediately stick to the first film, so that you do not have time to squeeze out the water in the two layers of film, not only will it produce bubbles and water bags, but also become larger and more over time.

If you want the light in the car to be darker, you can choose a film with low light transmittance, and you don't need to apply two layers. But the expert's opinion is that the current Ministry of Public Security of the People's Republic of China "Automobile Window Glass Sunshade Film".

Visible light is required for all automotive front windshield films.

The transmittance must be greater than 70%, otherwise it will affect the driver's vision and cause traffic hazards.

Currently, visible light transmittance, visible light reflectance, thermal insulation rate, ultraviolet light.

The barrier rate is one of the four commonly used car films.

Performance metrics. According to the principle of optics, the basic relationship between the first three is: the higher the light transmittance, the lower the thermal insulation rate; The higher the reflectivity, the higher the thermal insulation.

The high reflectivity will bring great hidden dangers to the safety of car driving. Meeting the three requirements of high light transmittance, high heat insulation and low reflection is the highest level of today's automotive film technology. Therefore, when choosing a car film, all car owners must balance and compare, and cannot choose high reflectivity simply for high heat insulation, which will cause unnecessary hidden dangers to future driving.

Hope it helps, hope!

It cannot be pasted in two layers, the most important thing is to prevent riots and sunlight.

Hello landlord, this is completely fine, but the cost may be more than ordinary.

The car glass film can be pasted with a double layer, but it is not necessary, and it may affect the normal light transmission, and one layer is enough.

Auto film is a film on the front and rear windshields, side windows and sunroofs of the vehicle, and this film-like object is also called solar film or explosion-proof heat insulation film. Its function is mainly to block ultraviolet rays, block part of the heat and prevent the sudden burst of glass caused by injury, and at the same time, according to the one-way perspective performance of the solar film, to achieve the purpose of protecting personal privacy. In addition, it can also reduce damage caused by UV exposure to the contents of the vehicle and personnel, which in some ways can save fuel consumption.

The production of automotive glass is to heat the glass to close to the softening temperature in the heating furnace, and then quickly send the glass into the air grid with different cooling intensities to cool the glass unevenly, so that the main view area of the glass and the surrounding area produce different stresses.

The surrounding area is in the strong wind position of the wind grid, so it needs to be fully tempered, the fragmentation degree of this position is good, the tempering strength is high, and the main viewing area is in the weak and cold position of the wind grid, the fragments are large, and the tempering strength is low.

Hello, yes, I hope it can help you, I wish you a happy car, thank you.

It is best not to, the film is too thick, which will affect the normal lifting of the glass.

Hello, there is no need to post two, it is easy to blister in summer.

Hello, if the first layer is not damaged, it can be pasted.

There's no need for this.,Two layers are easy to fall off.,It's enough to stick one layer.。。

Yes, it's darker.

Why do you need to paste two layers, the light transmittance is not generally poor, and there will be potential driving safety hazards.

Car wrapsAnother layer of film can be pasted on it.

The role of car film:

1) Create the most beautiful sense of beauty. When you envy the beauty of the glass color of the high-end imported car, the explosion-proof solar film.

Make this beauty a reality in your car.

2) Improve explosion-proof performance. Explosion-proof solar film can improve the safety level of the car in the event of an accident, minimize the possibility of car glass breakage, and avoid the injury to the occupants of the accident to the greatest extent.

3) Improve the efficiency of air conditioning. The thermal insulation rate of automobile explosion-proof film can reach 50%-95%, which effectively reduces the use of automobile air conditioning, saves fuel and improves air conditioning efficiency.

4) Resist harmful UV rays.

Ultraviolet radiation has a bactericidal effect, but it is also invasive to human skin, for the occupants, when riding for a long time, the human body is in a static state, at this time it is easier to love ultraviolet damage, causing ** disease. Sunscreen and heat insulation film.

It effectively blocks UV rays and protects your skin.

5) Ensure the privacy of the ride.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can be consulted at any time to ask the car to ask the question, 24 hours ** answer.

Lack of pickpocketing The second time the car film is more troublesome, especially the old car, the use time is longer, a lot of dust enters between the glass gaps, and the torn film will generally fall off the glue, and the cleaning of the remaining glue will cause debris, which will affect the cleanliness required for the film. And if it is a new car, it is almost spotless, very clean, and the relative cleanliness of the sticker is very good.

The damage of the secondary film to the car is not voltaic and large, because the most important step of the secondary film is to clean up the glue left over from the first film, if it is not treated well, it may scratch the glass, affecting the appearance, and there is not much damage to the car.

However, when sticking the film, it should be noted that when choosing the front and windshield film, do not choose to add a heat absorber or other products, because my country's regulations require that the light transmittance of the front windshield film should reach 70%, clarity and safety are the most basic requirements of the front windshield, and the addition of heat absorbers to the front windshield is like a human eye mixed with something, and it will be unclear to see things.

Moreover, it is also necessary to pay attention to the rear windshield glass is different from other glass, the rear windshield has the existence of heating wire, which is printed on the glass at one time when the automobile manufacturer is manufactured, which is extremely fragile in itself, and if it is not handled properly in the process of tearing off the old film, it is very easy to break the heating wire, thus losing the rear window defogging function. When the heating wire is broken, there is no way to repair it, only to replace the glass.

Expert advice: After the vehicle is filmed, try not to paste or hang things directly on the window, so as not to open the gap between the film when pulling up the orange slap suction cup and paste.

Try to avoid washing the car within three days after applying the film, so as not to cause the film to fall off due to the moisture not drying. Try not to open the rear window defogging line within a week, and it is easy to have a negative impact on the defogging line if the moisture is not dry.

After attaching, you can wipe the film surface with a damp towel, sponge or soft cloth. In addition, some time after applying the film, you will notice that there is a foggy water vapor inside. This is a normal phenomenon in the process of drying the solar film, and it will slowly disappear after a while.

Within a few days after the film, we should try to avoid lifting the window, and the film edge is very clever, easy to grind and curl in the process of 5 on the window, and the film that has not been fully bonded is also prone to displacement.

<> "Do cars need film?

Cars can be filmed. The film plays the role of sound insulation, so that you will not feel so hot in the car in the summer, even if you don't turn on the air conditioner.

Sunlight contains a lot of ultraviolet rays, people often tanned, some people say, the world car and not tanned, so do not pay attention, but the sun will make the paint and interior aging.

In order to ensure the safety and use of the dust search liquid for your car, you can try to put a film, I believe that if you apply ** and apply a film to your mobile phone, you will not let your car be hurt a little.
