How to identify the authenticity of the automobile film, and what is the method of distinguishing th

1.In terms of clarity, regardless of the color of the film, high-quality film should be able to clearly see items 6m away at night, while low-quality film will have a foggy feeling.

2.From the point of view of hand feel, the ** film feels thick and smooth, while the inferior film feels thin and brittle, and is easy to wrinkle.

3.In terms of color, the color falls off after tearing off the inner lining of the car film with a fingernail.

4.From the perspective of thermal insulation, thermal insulation performance is one of the important indicators of glass protective film, and this is difficult to identify by the naked eye and feel alone. This can be compared with a simple test method:

Put a piece of glass sticking to the car film on an iodine-tungsten lamp, and use it without feeling a trace of heat is a high-quality film. There are only a few manufacturers of heat insulation film of truly internationally renowned brands, and in the current market product cost performance is uneven, it is particularly important to identify internationally renowned brands and require international brand quality assurance. I highly recommend Johnson & Johnson, V&G's automotive films.

In addition, now many businesses say that their membranes are imported from abroad, in fact, there are not many car film manufacturers in the domestic market that really have overseas production plants, only Weigu, Johnson & Johnson, Bekaert Quantum, and Dragon Film. Other brands of car films are made by small factories and then marked with various logos, and there is generally no guarantee.

1 UV protection.

To test the degree of ultraviolet protection of the film, you can take the film to the test pen, and then put a piece of 100 yuan under the film, because the test pen to check the authenticity of the RMB is through ultraviolet rays, so that the watermark of the anti-counterfeiting mark 100 yuan on the RMB is displayed. Therefore, if the film is placed on the RMB, if the UV protection function is good, then the 100 yuan watermark on the RMB will not be displayed, on the contrary, the UV protection ability of this film is not good.

2 Identify the color of the membrane.

Pour a little gasoline on the film, and then scratch it with your fingernails, if the color of the film is crossed out at once, it means that the film is just a little color added to the film paper, the appearance looks fine, but it is far from the effect of the film, no matter how the really good film is scratched, it will only fall off the glue, will not fade.

3. Measure the metal layer.

Good films contain metal layers, you can compare high-quality films with inferior films, hold the film in your hands, and gently flick the film with your fingers, because the high-quality film contains metal layers, so the sound is generally very crisp, and the sound of the inferior film is muffled, at this time the owner friend has to carefully inspect.

4 Check the fluoroscopy of the membrane.

The perspective of the general film should reach more than 70%, so that the owner can maintain a clear line of sight, less than 70%, the car owner's vision is blurred when driving, which is easy to cause accidents.

5 Thermal insulation.

Standardized businesses generally have a thermal insulation effect testing room, car owners may wish to try, the thermal insulation of high-quality film can well block the sun's rays.

6 Choose a professional technician.

Try to choose a professional brand beauty care store, use brand explosion-proof heat insulation film to apply film to your car, and use a dust-free workshop and professionally trained film technicians.

It should be difficult to distinguish the film that has just been pasted, mainly to see if there are bubbles between it and the glass, and whether there are signs of rolling up on the edges.

The most important point of a regular brand is to have a registered trademark from the State Trademark Office, and you can let the film shop provide a look at the registered trademark.

One look at the color. Usually, the anti-riot film is made of lighter green, sky blue, gray, brown, natural color and other colors that are more comfortable for the eyes. The color of the explosion-proof film is uniform and soft, without the uneven color difference of the wave depth, and the scenery from the inside of the car will not change color naturally.

The ordinary color film is to melt the color directly into the adhesive film, after tearing off the upper layer of plastic paper, scrape the paste surface hard, and the color will fall off. In addition, if the ordinary color film is gently rubbed on the ground, the color will fade. Second, smell the smell.

In the residual solvent of the adhesive layer of the inferior film, the benzene content is high and there will be peculiar smell, while the good film has been professionally treated before leaving the factory, and the peculiar smell is small.

Three questions about indicators. The so-called explosion-proof film, hail shortage must have the effects of heat insulation, explosion-proof, anti-ultraviolet rays and so on. Therefore, when consumers choose, they can consult the sales staff in detail about the relevant situation, so as to judge the authenticity of the quality and the source of good and bad.

Fourth, touch the feel. Generally, the thickness of the safety explosion-proof film is not lower, so it feels thick and smooth to the touch. In addition, because the surface is hardened, it generally does not scratch the surface.

However, due to the lack of thickness, the ordinary color film feels thin and brittle, and in the process of shaking the glass, it will leave marks on the film.

Millions of car purchase subsidies.

1.The logo of the new Ray-Ban has been changed to "LetBon Ray-Ban", so please be sure to read it clearly. 2.

Real Ray-Ban professional construction shops have construction authorization plates. 3.The real Ray-Ban has a watermark with the word "Ray-Ban" printed on the surface of the film, which can be removed by scrubbing with alcohol.

The word "Ray-Ban" on the fake Ray-Ban film has a concave and convex feeling. 4.The color of the real Ray-Ban film is evenly coated inside the film, while the fake film is the color produced by putting the pigment directly into the adhesive layer, just take a small film, tear off the protective layer (centrifugal paper), spray it on the adhesive layer with carburetor cleaner, and scrape it with a fingernail, and the fake film will fade and become transparent.

5.The ultraviolet blocking rate of the real Ray-Ban film is more than 99%, you can use the ultraviolet lamp of the money detector to aim at the anti-counterfeiting seal of the RMB, take a small film and put it between the light source and the RMB, if it is a real film, you can see that the ultraviolet rays weaken or even disappear.

First of all, look at the thermal insulation performance of the membrane, because the DuPont membrane uses high-performance polyester membrane, the car film has good thermal insulation performance. Thermal insulation performance that is far from that of false film garbage film.

Method Step 2:

In addition, the membrane used by DuPont membrane has no peculiar smell, and the general membrane will emit peculiar odor after a period of use. You can stick to the car and smell it. If there is a peculiar smell, it is a fake film.

Method Step 3:

The other is the light transmittance of the film, DuPont has good light transmittance, clear and not blurry, and good one-way line of sight. Generally, the membrane will be unclear and blurry. Even blistering.

Method Step 4:

In addition, in the film, pay attention to see whether the film used in the measurement and the film pasted on it is a film, and some bad businesses will also drop the bag.

At present, the best-selling Japanese nano space film and the American 3M heat insulation film.

The best one is 3M

It depends on the situation.

**Generally more than 2000.

And then there's Ray-Ban.

Weigu, Dragon Film, Johnson & Johnson.

Car film can save fuel because the film can block light, especially infrared and ultraviolet radiation, effectively control the greenhouse effect formed by the sealed compartment, and greatly reduce the fuel consumption of automobile air conditioning, so as to achieve the effect of energy saving. Qiaoshou Car Service Company once conducted an experiment by adding the same grade and capacity of gasoline to two Jetta taxis in basically the same condition.

After 24 hours of driving on the same route and at the same speed, it was found that the Jetta car with the film saved nearly 3 liters of fuel.

At present, most of the more popular car films on the market use Japanese nano space film and American 3M heat insulation film. For example, the Japanese nano space film NM A3000 has a total of 7 layers of film material, which filters out infrared rays (the main heat source in sunlight) and ultraviolet rays in different wavelength bands of sunlight, with a thermal insulation rate of 93, an ultraviolet blocking rate of 100, and a visible light transmittance of 78. Experiments have shown that the temperature difference between the two sides of the membrane can be as high as more than 15 under the irradiation of a 500 watt heat lamp.

The obvious temperature difference will cause a significant difference in the fuel consumption of the car air conditioner.

In addition to the fuel-saving function of car film, it is closely related to the quality of the film, and it also has a great relationship with the technical process of the film. High-precision, high-tech film technology helps to improve the functions and aesthetics of the film such as sun protection, heat insulation, and anti-riot, which is conducive to giving full play to the fuel-saving function.

Generally speaking, the ** of car film is relatively high, and it is necessary for consumers to consider and choose carefully. The person in charge of Qiaoshou Automobile Service Company reminds consumers that when choosing a membrane, the most important thing is to look at its price-performance ratio, and do not be deceived because of some small discounts; At present, the best-selling Japanese nano space film and the United States 3M heat insulation film, there are many counterfeit products on the market, and the authenticity must be carefully confirmed when purchasing, specifically through the identification of the certificate of the film manufacturer and the laser anti-counterfeiting identification or watermark of the identification product; When choosing a service business, try to choose a good integrity, good after-sales service, scale, on-site installation, and indoor installation environment.

In addition to the light transmittance, the higher the heat insulation rate, the better, the higher the ability to isolate ultraviolet rays, the better, and the lower the radio signal blocking rate, the better.

Maybe someone will suggest that you post 3M or Ray-Ban, but I still have to remind you that the market is too mixed now, and there are a lot of counterfeits, not a little yo, you must be optimistic about the 4S store, I suggest not pasting, because the one that produces cars has a solar film. Think for yourself.

At present, there are more than 3,000 kinds of car film brands in the domestic market, which are not quite the same, and are generally divided into: imported regular brands, OEM brands, OEM brands, counterfeit brands and the so-called original films. All kinds of automotive films are mixed, ** is not very standardized, 4S stores, online purchases and other ways to buy the same brand of automotive film quality is also very different, the current popular film on the market is dragon film, Weigu, 3M,G+ membraneWait.

1.Look at the license plate and warranty card.

Check whether the car film is a regular source, you can see whether there is an authorized brand and warranty card of the brand, you can see that the car film in the regular 4S store is a franchised dealer, then the quality will be more guaranteed, if there is no this, it may not be regular**or not**. Most brand warranty cards are printed with a number, with the manufacturer** and the testing location on it, which is convenient for inquiry, if there is no number or business information on the warranty card, it is also problematic.

2.Look at the packaging.

Now a lot of counterfeit brand **** packaging is sold, this method is not only car film, I believe you have seen it in other products, so before the film, it is necessary to check whether the volume number on the packaging and the film shaft is consistent, whether the label has been processed, if you find traces of alteration, it is very likely that the ** packaging is shoddy. Regular big brand car film packaging chicken film shaft has the corresponding label and volume number, which is a normal circulation link must have the characteristics, most of the regular channels of automotive film, ** business will also print the logo on the packaging box.

3.Look at the anti-scratch effect.

The car film has the characteristics of protecting the car glass, just like the mobile phone tempered film, you can use your fingernails to scratch a few times on the film when choosing, if it is easy to scratch, it may be a fake film or a bad quality film, such a film can even damage the nails, not to mention explosion-proof. The ** film has an anti-scratch coating that will not be damaged so easily. Therefore, the service life and warranty period of a good car film are also longer.

4.Touch with your hands.

The car film is attached to the glass, a good glass film will have a thick feeling and a smooth feeling to the touch, the surface is hardened, and it will not be wrinkled easily, while the inferior film will be thinner and not so hard, due to the lack of good treatment technology, it is easy to wrinkle with a slight fold, but this is a more subjective means, some people can feel the difference, and some people feel little.

5.Definition.

Regardless of the color shade, it can ensure good clarity and light transmittance, and good clarity is a prerequisite for ensuring driving safety at night and in rainy days. Inferior films will have light distortion, and some will have a foggy and unclear feeling. After using it for a period of time, there will even be serious fading, and many inferior films are colored by the method of viscose coloring, adding pigments to the viscose, and then coating on the colorless transparent film, commonly known as dyeing film.

This kind of film does not have the function that a normal car film should have.

Here, it is recommended that you go to the franchise store of regular film, and at the same time, the more expensive ones will be more reliable than the ridiculously cheap ones.

How to identify inferior membranes?

In such a chaotic market environment, how to identify inferior membranes is particularly important, in fact, the way to identify is simple.

Method 1: You can ask the merchant to cut a small piece of film down, and take a photo on the bright side, the clarity of the film is higher, and the inferior film looks foggy.

Method 2: After tearing off the protective layer, the inferior film smells pungent and has a pungent smell, while the file film has a faint glue smell or basically no taste, which is related to the environmentally friendly glue it uses.

Method: The film is thick and smooth to the touch, while the inferior film is soft, not tough, and easy to wrinkle.

Summary: It is recommended to pick up this kind of film yourself, and you still have to choose those with a better reputation, just like Meiji, but I still prefer Meiji, and I have been using it, and finally I still persuade you not to buy inferior car film, which is no different from running naked, and it costs money in vain.
