How many types of solar films are there and how to identify them?

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 is the explosion-proof heat insulation film with the metal layer coating reflecting infrared rays, which has the functions of wear resistance, semi-reflective and explosion-proof, and 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 rays are 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.

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.

If you are interested, you can learn a lot about solar film.

Although automotive solar film has many functions, in the market, real and fake solar film is still unstoppable for consumers, and there is a helpless gap between the real and fake solar film and the real and fake solar film. How to distinguish a real solar sheet from a fake? Let's take a look.

The first thing to learn is**. When we use solar film**, if the reflectivity of ordinary solar film is too high, it is easy to form specular reflection, which is easy to cause visual interference. If the better solar film has better light transmittance, the line of sight will be clearer.

Then sniff it. When you tear off the adhesive line, if you smell obvious chemicals, it may be bad or fake, because high-end solar film can't smell it. In order to let everyone feel the difference in taste between the two membranes more clearly, I used an air detector to roughly measure the harmful gas content of the lower membrane, and the formaldehyde value of the ordinary membrane increased significantly.

In addition, it is touching the film surface. The so-called &ldquocut&rdquo is to touch the surface of the solar film with your hands. Because ordinary films will inject color into the adhesive layer, the adhesive layer will be particularly thick, which will indirectly affect the elasticity of the film surface.

I've seen people say on the Internet that a good quality solar film can resist scratches from sharp objects, and you can use a car key to pass through the membrane surface to identify it when you buy it. It should be noted that this method is not suitable for window solar films. The density of a high-quality film is high, but it is not enough to resist scratches.

Millions of car purchase subsidies.

How to distinguish between sun film and how to maintain after filming?

1. Look at the color.

The silver color of the sun film is generally lighter green, sky blue, gray, brown, natural color and other colors that are more comfortable for the eyes.

2. 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.

3. Ask for indicators.

The so-called explosion-proof film must have the functions of vandal-proof, heat insulation, and UV-proof. Therefore, when we buy solar film, we can ask the salesman in detail about all aspects of the situation, so as to judge the quality of the solar film.

4. Feel the touch.

Generally, the thickness of the safety explosion-proof film is not less than 2mil, so it feels thick and smooth to the touch. In addition, because the surface is hardened, it generally does not scratch the surface.

Maintenance after car wrapping

There are many car owners who only know how to give the car a suitable film, but for the maintenance of the film and the protection of the car, they are slow to give indifference, so they will find that it does not take long after the film to be filmed, and the car film will experience scratches, bubbles, and dullness. So I here's calling on the majority of car owners to maintain after the film is applied.

1. Do not frequently lift the glass within 3 days after the film, because the glass and the film should have a running-in period after the film, so that the glass and the film are closer. Very important and important to pay attention to.

2. Bubble treatment If there are bubbles after the film, they should be dealt with in time, do not expand the range of bubbles, and do not let children buckle bubbles.

3. Special reminder for winter maintenance Shenzhen car maintenance: it is best not to lift the glass and wash the car within 1 month after the winter film, because the front and rear gears dry slowly. In particular, don't open the rear gear within a month, because if you open the film in winter, bubbles will be generated around the film, and these bubbles cannot be repaired and will cause unnecessary losses.

Although there are many functions of automotive solar film, in the market, real and false solar film still makes consumers unable to prevent it, and there is really a helpless gap between the quality of the solar film and the real and false solar film. How to distinguish a real from a fake solar film? Let's take a look.

The first thing to learn is to observe. When we use solar film**, the high contrast of ordinary solar film is easy to form specular reflection, which is easy to cause visual impairment. If a better solar film has better light transmittance, the line of sight will be clearer.

Then there's the smell. When tearing off the adhesive layer, if Wuyouzi smells obvious chemicals, it may be inferior or fake, because the high-end solar film cannot be smelled. In order to let you feel the difference between the two films in taste more clearly, I used an air detector to roughly measure the harmful gas content of the membrane, and the formaldehyde value of the ordinary membrane increased significantly.

Also, touch the surface of the film. The so-called "cut" is to touch the surface of the solar film with your hands. Because the ordinary film will inject color into the adhesive layer, the adhesive layer will be particularly thick, which will indirectly affect the elastic cover of the film surface.

Some people on the Internet say that high-quality solar film can resist scratches from sharp objects, and you can use a car key to pass through the membrane surface to identify it when you buy it. It should be noted that this method does not apply to solar films for car windows. Although high-quality membranes are dense, they are not enough to resist scratches.

<> "How to Choose a Solar Film.

In hot weather, the demand for sunscreen film for automobiles is often stronger than that in other seasons, and there are many brands of sunscreen film on the market, how to choose the right one?

At present, the products on the market, products from the United States occupy a certain advantage. Of course, because of the different production technologies and processes, there are certain differences in the products of various brands, but when consumers choose, try to choose the top ten brands recognized by the current market.

Because although there are many solar film products at present, there are not many brands that take the brand route, and these big brands are products that have been tested by the market, which can protect the rights and interests of consumers to a greater extent. Putai's Wang Wei potato type believes that in the past, the solar film market has been monopolized by foreign brands for a long time, but since last year, this monopoly has begun to be broken, domestic brands have begun to appear, and those regular domestic brands are also guaranteed in terms of product quality, so consumers can fully compare the performance when choosing, and choose a product that is most suitable for them.

Of course, if you want to do a good job, you must first sharpen your tools, although most consumers are not professionals, but it is still necessary to learn some professional knowledge.

In terms of how to distinguish the quality of the solar film, the expert's tricks are all set in a set. Pei Jianwei and Li Xuguang believe that the main criteria for the worst of solar film are: thermal insulation performance, anti-ultraviolet performance, light transmittance and safety.

A good solar film, without a cloudy feeling, surpasses those products with lower quality in terms of thickness, anti-scratch function and environmental protection and no peculiar smell.

The expert told you the tricks of observation: in addition to the authorized key hand touch certificate of the regular product, the light transmission and color of the product are also relatively uniform, and there is no wave color difference. The material used for the lining film is also clear and transparent, the texture of the roll film is better, the length of the film is generally 30 meters, and sometimes you can distinguish the damage of the solar film if you pay attention to it.

The real sun film has a strong texture, elasticity, good light transmittance, is clear even at night, and has no peculiar smell. And the fake ones are mostly soft, fuzzy, and smell disgusting.

In addition, there is another difference between the real big brand solar film and the fake solar film is the difference in warranty and after-sales service. Gao Weihua of Badenweiler Solar Film, Wang Chao of Belkart Quantum Film, and Shi Xiaoke of 3M all pointed out that the warranty period of big brand products is generally relatively long, and there are regular warranty certificates from manufacturers, such as 3M and special electronic warranty certificates from manufacturers, which are not available in those counterfeit products.

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.
