How many layers does a car film consist of? Isn t it better to have as many layers as possible?

Generally speaking, high-quality, well-effected automotive films.

It is composed of eight layers of materials with different molecular structures, namely wear-resistant layer, metal insulation layer, thin adhesive layer, colored polyester layer, UV absorbing layer, protective layer, transparent PET safety base layer, and highly transparent PET release film.

It's not always the case that more layers are better, because light transmission is also a concern.

These materials with different molecular structures provide different roles in the lamination and use of automotive films.

1. Wear-resistant layer.

This layer is used on the surface of the car film to reduce wear and prevent scratches on the film surface, which is usually called the anti-scratch layer.

2. Metal thermal insulation.

This layer is a nano-scale metal layer that combines aluminum, silver, nickel, etc. against infrared.

It has a high reflectivity.

The metal is formed using vacuum magnetron sputtering technology.

3. Thin adhesive layer.

This layer is a polyester adhesive with good durability and high transparency.

Its function is to bond the layers of the car film together.

4. Colored polyester layer.

This layer is a color layer, made of high-strength, high-transparency polyester dyes.

Melt formed and has a service life of more than eight years.

5. Ultraviolet absorbing layer.

This layer is made of a special UV absorber that effectively blocks sunlight.

99% of harmful ultraviolet rays.

6. Protected adhesive layer.

This layer is the binder layer that is used to bond with the glass.

7. Transparent polyester safety base.

This layer is composed of high-strength, high-transparency polyester, which is used to sandwich the metal layer in the middle, preventing metal oxidation and extending the life of the film.

8. Highly transparent polyester release film.

This layer acts as a protective binder layer when automotive film rolls are wrapped and cut to size.

The product process structure of automobile explosion-proof heat insulation film is composed of seven layers, including wear-resistant outer layer, safety base layer, heat insulation layer, anti-ultraviolet layer, pressure-sensitive adhesive layer, easy-to-construct adhesive grinding layer, and transparent substrate, which fully realizes the functions of explosion-proof, sunscreen, ultraviolet isolation and anti-glare. The appearance of the automobile explosion-proof heat insulation film composed of seven layers is a thin film with the naked eye, but in fact, the regular high-grade explosion-proof heat insulation film is a multi-layer structure, and the production process is extremely complex. Explosion-proof film is a metal film installed on the upper part of the pressure vessel to prevent the container **, which is a safety device, also known as explosion-proof disc or bursting disc.

When the pressure in the vessel exceeds a certain limit, the film is broken first, so the pressure in the vessel can be reduced, and it is widely used in pressure vessels.

At present, the most advanced explosion-proof heat insulation film has a variety of effects such as heat insulation, explosion-proof, and ultraviolet protection. In fact, the structure of a real explosion-proof heat insulation film is not simple, and its production process is also extremely complex. As far as Uma film is concerned, the process structure of its products is composed of a safety base layer, a polyester layer, a special metal coating, a wear-resistant layer, an ultraviolet barrier layer, a special adhesive layer, etc.

Each level plays an extremely important role in bringing comprehensive protection to your car, and the main functions of each level are:

Safety base. It has a very strong impact resistance to prevent the glass from bursting and splashing, which constitutes the explosion-proof function of the automotive film.

Polyester layer. With anti-glare, one-way perspective and other functions, so that your vision is clearer, and driving is safer and more comfortable.

Special metallic coatings.

The use of indium tin oxide (ITO) can enhance light transmission, effectively block infrared and ultraviolet rays, and achieve the function of thermal and ultraviolet insulation without affecting the satellite navigation system.

Wear layer. It is very tough, super wear-resistant, and has the greatest strength to prevent the car film from being scratched, and to maintain the aesthetics of the car film for a long time.

UV barrier layer.

Block ultraviolet rays, avoid redness and blackening of the human body, and reduce the probability of cancer, cataract eye diseases, etc. At the same time, it can also effectively prevent the interior of the car from aging and fading due to ultraviolet radiation.

Special adhesive line. The special adhesive layer created for automotive glass can make automotive glass and automotive film truly become one and stick tightly together.

Three basic components:

Mylar. Metal plating or coloring components.

Laminating, mounting adhesive.

2. Three additional components:

UV absorbents.

Anti-stick protective film.

Abrasion-resistant coating (also known as anti-scratch layer).

3. The production process is to combine these six elements, and this is how quantum films are produced.

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.

It can be divided into four types: dyed film, semi-reflective paper, explosion-proof heat-proof film with metal-coated reflective infrared rays, and explosion-proof heat-proof film with non-metallic layer for heat insulation.

The first is the "dyeing film", that is, the ordinary film, the main component is the dyed ordinary chemical film with viscose, this kind of heat insulation film is used as if it is cellophane of the lamp, neither heat insulation, nor ultraviolet protection, not explosion-proof, and its shading property is easy to cause traffic accidents when the car driver is driving, and it will slowly fade after a long time, and it will emit odor gas after heating, which endangers human health.

The second is "semi-reflective paper", which is usually the kind that car dealers give to users, with a thermal insulation rate of about 20% to 30%, and the surface will oxidize and deteriorate after one or two years of use. Therefore, when buying a new car, you should pay special attention to whether the film you give yourself belongs to this category.

The third kind of explosion-proof heat insulation film with metal layer coating reflecting infrared rays, with wear-resistant, semi-reflective and explosion-proof functions, ultra-thin metal coating can selectively reflect the infrared rays in the sun, so as to have the function of heat insulation (infrared is heat**), and the heat insulation rate can reach more than 50%. This is the main type of high-grade explosion-proof heat insulation film.

Fourth, the use of non-metallic layer for heat insulation explosion-proof film, the use of non-metallic layer for heat insulation explosion-proof film: do not use metal coating to reflect infrared, but the use of polymer materials as a pure heat insulation layer, the advantage is that the heat insulation film has extremely high light transmittance, and the isolation effect of the glare is very strong, the heat insulation rate is also very good, it is not easy to cause the reflection of the front windshield, so that the driver's driving safety has been improved a lot.

The grades of automotive glass films can be roughly divided into four types:

The first kind, the dyeing film, that is, the so-called ordinary film, the main component is the dyed ordinary chemical film with viscose, this kind of heat insulation film is used like the cellophane of the lamp, neither heat insulation, nor ultraviolet protection, not explosion-proof, at the same time, its shading property is easy to cause traffic accidents when the car driver is driving, it will slowly fade after a long time, and it will emit odor gas after heating, which endangers human health.

The second type, semi-reflective paper, this kind of car film is usually the kind given to users by car dealers, the thermal insulation rate is about 20% to 30%, and the surface will oxidize and deteriorate after one or two years of use. Therefore, when buying a new car, you should pay special attention to whether the film you give yourself belongs to this category.

The third kind of explosion-proof heat insulation film with metal layer coating reflecting infrared rays, with wear-resistant, semi-reflective and explosion-proof functions, ultra-thin metal coating can selectively reflect the infrared rays in the sun, so as to have the function of heat insulation (infrared is heat**), and the heat insulation rate can reach more than 50%. This is currently the main type of high-grade explosion-proof heat insulation film.

Fourth, the use of non-metallic layer for heat insulation explosion-proof film, the use of non-metallic layer for heat insulation explosion-proof film: the current type of the most high-tech heat insulation film, such as the master film industry of the canopy is this, does not use metal coating to reflect infrared, but the use of polymer materials as a heat insulation layer, the advantage is that the heat insulation film has high light transmittance, and the isolation effect on glare is very strong, the heat insulation rate is also very good, it is not easy to cause the reflection of the front windshield, so that the driver's driving safety has been improved a lot.

At present, the grades of automotive films on the market can be roughly divided into four types:

1. "Stained film".

That is, the so-called ordinary film, the main component is the dyed ordinary chemical film with viscose, this kind of heat insulation film is used as if it is cellophane of pasting lamps, neither heat insulation, nor ultraviolet protection, not explosion-proof, and its shading property is easy to cause traffic accidents when driving car drivers, and it will slowly fade after a long time, and it will emit odor gas after heating, which endangers human health.

2. "Semi-reflective paper".

This kind of automotive film is usually the kind given to users by car dealers, with a thermal insulation rate of about 20% to 30%, and the surface will oxidize and deteriorate after one or two years of use. Therefore, when buying a new car, you should pay special attention to whether the film you give yourself belongs to this category.

3. Explosion-proof heat insulation film with metal layer coating reflecting infrared rays.

With wear-resistant, semi-reflective and explosion-proof functions, the ultra-thin metal coating can selectively reflect the infrared rays in the sunlight back, so as to have the function of heat insulation (infrared is heat**), and the thermal insulation rate can reach more than 50%. This is currently the main type of high-grade explosion-proof heat insulation film.

4. Explosion-proof heat insulation film that uses non-metallic layer for heat insulation.

At present, the most high-tech type of heat insulation film, such as 3m's infinite scenery is this, does not use metal coating to reflect infrared rays, but uses polymer materials as heat insulation layer, the advantage is that the heat insulation film has extremely high light transmittance, and the isolation effect of glare is very strong, the heat insulation rate is also very good, it is not easy to cause the reflection of the front windshield, so that the driver's driving safety has been improved a lot.

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 of the film when pulling up the 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 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 you mean to apply the film again after applying it once, that is, to paste 2 films on the same glass?

If that's the case, I'll tell you that it's absolutely no problem, because I'm from an automotive film factory, and my car is often like this, and when a new product comes out, tear it off and paste a new one. I think I like the color is lighter, just paste it 2 times, it's good-looking, and it's super insulated and super explosion-proof, not that the big brands must be good enough, and the different film stickers 2 together This effect is very good. Sissy...

After the new car leaves the factory, the body comes with its own protective film. This protective film is not as effective as crystal plating or coating.

Because the protective film of a new car can protect your body for at least more than a month. When the car leaves the factory, in order to protect the paint, there is also a layer of wax film, which is often called coarse wax, to protect the paint from damage.

So all new cars have wax mouths. Now it is necessary to use special wax boiling water to open the wax, and then clean the surface treatment again. Finally, it is necessary to apply new wax to ensure the smoothness of the car.

Car waxing, as a traditional item of car beauty, was first used to use tung to be waterproof and acid-proof rain. Due to the protection of the wax, the amount of water droplets adhering to the body is reduced.

Waxing frequencyTheoretically, the time interval between car waxing depends on the length of time the wax layer stays on the paint surface, and this time depends on the performance of the wax.

The grades of automotive glass films can be roughly divided into four types:

The first is the dyeing film, which is generally called the ordinary film, the main component is the dyed ordinary chemical film with viscose, this kind of heat insulation film is used as if it is cellophane of the lamp, neither heat insulation, nor ultraviolet protection, not explosion-proof, and its shading property is easy to cause traffic accidents when the car driver is driving, and it will slowly fade after a long time, and it will emit odor gas after heating, which endangers human health.

The second is semi-reflective paper, which is usually the kind given to users by car dealers, with a thermal insulation rate of about 20% to 30%, and the surface will oxidize and deteriorate after one or two years of use. Therefore, when buying a new car, you should pay special attention to whether the film you give yourself belongs to this category.

The third kind of explosion-proof heat insulation film with metal layer coating reflecting infrared rays, with wear-resistant, semi-reflective and explosion-proof functions, ultra-thin metal coating can selectively reflect the infrared rays in the sun, so as to have the function of heat insulation (infrared is heat**), and the heat insulation rate can reach more than 50%. This is currently the main type of high-grade explosion-proof heat insulation film.

Fourth, the use of non-metallic layer for heat insulation explosion-proof film, the use of non-metallic layer for heat insulation explosion-proof film: the current type of the most high-tech heat insulation film, such as the master film industry of the canopy is this, does not use metal coating to reflect infrared, but the use of polymer materials as a heat insulation layer, the advantage is that the heat insulation film has high light transmittance, and the isolation effect on glare is very strong, the heat insulation rate is also very good, it is not easy to cause the reflection of the front windshield, so that the driver's driving safety has been improved a lot.

Automobile film can be simply divided into two categories, one is automotive glass film, which is pasted on the automotive glass to control sunlight. Its basic properties include safety, clarity, anti-glare, UV protection, heat insulation, scratch resistance, adequate shelf life and privacy protection. The other type is the new car film product introduced by AAA company into the United States STI by AAA company, the basic performance includes personalized decoration, protection of car paint, and easy scrubbing.
