How to distinguish the quality of explosion proof film?

1. See if the electroplating layer is uniform.

Pick up a piece of building explosion-proof film, whether its electroplating is uniform, the uniform is the best film, and the uneven is the poor quality film.

2. Carburetor cleaner test method.

Use a piece of film to rub on the ground or spray carburetor (also known as "chemical detergent") on the film, and the color will fade into an inferior film, which is commonly known as a stained film. The one that does not fade is a high-quality film, that is, the primary color film.

3. See if there is an electrostatic attraction.

Since there is very little metal material used in the low-grade film, it will slide from side to side when the low-grade film is rubbed; The high-grade film has a kind of electrostatic attraction due to the fact that it contains more metal materials, so it does not slide when rubbing.

4. Illumination analysis method.

Because the thermal insulation effect of different grades of membrane is different, we can use high-power solar lamps (500W-700W) to irradiate the surface of the membrane. If the low-grade film has a poor thermal insulation effect, the membrane will also feel hot, while the high-grade membrane does not feel hot because there is almost no heat to penetrate it.

5. Distinguish from wear resistance.

The wear-resistant layer of the low-grade film is not wear-resistant, while the high-grade film is quite wear-resistant, so we get a piece of building explosion-proof film, and after distinguishing its protective layer, we only need to rub it on the wear-resistant layer a few times to see if it has a pattern. The one with the pattern is the low-grade film, and the one without the pattern is the medium and high-grade film.

Take you to understand: how to distinguish the quality of the film, whether the explosion-proof film is effective.

1. The light transmittance of the film: the light transmittance of the virtual omen film should be between 20% and 90%, and the light transmittance of the front baffle film should generally be more than 60%.

2. Thermal insulation performance: the thermal insulation rate of explosion-proof film is generally more than 50%, with high light transmittance and high heat insulation, which can improve comfort, greatly reduce the load of air conditioning and save fuel. Considering the low winter temperature and the starvation climate factors of the northern region, the window film should have high thermal insulation performance.

3. Explosion-proof performance: The high-quality explosion-proof heat insulation film is made of special polyester film as the base material, which is composed of multi-layer materials, and the glass can be glued to the film after it is broken, and it will not splash and hurt people, and has strong impact resistance.

4. Ultraviolet blocking rate: the index of high-quality explosion-proof heat insulation film is generally not less than 96%, and the high index can reach 99%.

In fact, if different brands of films are basically the same in the four data just mentioned, then there will not be too many differences in use, so you can choose cheaper products under the same circumstances.

1.Look at the color: From the appearance, the color of the real explosion-proof film is uniform and soft, and there is no uneven color difference of wave depth, so the scenery will naturally not change color when viewed from the inside of the car.

Ordinary color film is to melt the color directly into a glue film. After tearing off the plastic paper on it, scrape the rubber surface vigorously and the color will fall off. 2.

Odor: Generally, the residue solvent benzene content of the adhesive layer of the inferior film is high, which will produce peculiar smell, while the good film has been professionally treated before leaving the factory, and the peculiar smell is less. Smelling this odor for a long time will seriously affect the health of the car owner.

3.Inquiry index: The so-called explosion-proof film must have the effect of heat insulation, explosion-proof and anti-ultraviolet rays.

Therefore, consumers can consult the salesperson in detail when choosing, so as to distinguish the real and false quality and good and bad quality. 4. Cutting feel: The thickness of the general safety explosion-proof film is not lower, so it feels thick and smooth to the touch.

Due to the hardening of its surface, 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.

1. Look at the color:

2.In appearance, the color of the real explosion-proof film is uniform and soft, and there is no wave-deep color difference. The natural color of the scenery as seen from inside the car. The common color film directly melts the color in the plastic film, and the color will fall off if you tear off the plastic paper and scrape the plastic surface hard.

3.Smell: 4The content of benzene residue in the adhesive layer of inferior film is high, and there will be peculiar smell, while good film has been treated before leaving the factory and has little peculiar smell. Smelling this smell for a long time can affect the health of the car.

5.Ask Index:

6.The so-called explosion-proof film must have the functions of heat insulation, explosion-proof and ultraviolet protection. Therefore, consumers can consult the salesperson in detail when choosing, so as to judge the authenticity and quality of the quality.

7.Cutting Feeling:

8.The thickness of the explosion-proof film is m, so it feels thick and smooth. Because the surface is hardened, the surface can be scratched. The common color film is thin due to its thickness and feel, and it will leave traces in the process of shaking the glass.

Cars are already a must-have tool for everyone to get around. Of course, automotive knowledge is essential. In order to facilitate everyone to understand these knowledge, today Bian Xiao will introduce to you the difference between the quality of automobile explosion-proof film. If you are interested, it may be helpful to you.

The difference between good and bad automobile explosion-proof film: in terms of clarity: high quality has good clarity, and poor quality has a foggy feeling; Feel on:

**There is a heavy feeling, while the inferior feel is thin, brittle and wrinkled; Color: difficult to decolorize, poor quality and easy to decolorize; Thermal insulation: Put a piece of glass with a car film on the iodine-tungsten lamp.

If you don't feel a hint of heat, it's high quality**. Methods for identifying the quality of automobile explosion-proof film:1.

In terms of clarity, no matter how deep the color of the film is, high-quality film should be able to see things 6m away at night, while low-quality film will have a foggy feeling. 2.From the point of view, the ** film feels thick and smooth, and the inferior film feels thin and brittle, and it is easy to wrinkle.

3.From the color point of view, the pigment of the high-quality film is evenly integrated into the film, which is durable and not easy to change color. It may not change color after being scraped off by a scraper during the pasting process.

The color of the inferior film is in the adhesive that acts as a bond. After tearing off the inner lining of the car film, the color will fade if you scrape it with your fingernails. 4.

From the perspective of thermal insulation, thermal insulation is one of the most important indicators of glass protective film, which is difficult to identify by the naked eye and hand alone. It can be done by a simple test method: put a piece of glass with a car film on the iodine-tungsten lamp, and the high-quality film can not be felt without a trace of heat.

<> "How to identify the advantages and disadvantages of automobile explosion-proof film.

Nowadays, automobile explosion-proof film has become a necessary equipment for almost every car before it goes on the road, but the identification of the advantages and disadvantages of automobile explosion-proof film has been bothering many car lovers. To sum up, inferior car film has the following characteristics and hazards:

1. The low clarity of inferior solar film leads to blurred vision, dizziness, and slowed reaction, resulting in car accidents.

Second, the reflection of inferior solar film is too high, which often makes the items on the dashboard reflect on the front windshield to interfere with the line of sight, forming a potential safety hazard.

3. The thickness of the inferior solar film is not enough, and the viscosity is not strong, so it cannot block the glass with 0 splashes in the event of a car accident, resulting in physical injury.

Fourth, residual volatile substances, endangering human health. One of the inferior membranes is the dyeing film, I believe many friends have seen the dye and smelled the peculiar smell of the dyes. The chemical coatings in these stain adhesive lines will cause pollution in the car and harm human health.

Fifth, the chemical adhesive layer absorbs heat, causing hidden dangers in glass. Inferior film can easily cause glass to burst, and its characteristics: first, the chemical coating changes after heating, so that the original effectiveness is gradually lost; The second is to absorb heat and make the glass temperature beam too high, and the long-term thermal expansion and contraction will eventually lead to the glass bursting.

There is no doubt about the benefits of a good solar film to the car owner's wheels, I believe that many car owners have a deep understanding of this, so how to choose a suitable solar film for themselves is particularly important. According to the professionals of the well-known domestic brand Anji yellow hat store: the choice of solar film is not necessarily imported is necessarily good, in fact, whether it is imported or domestic, as long as it is a regular manufacturer, the quality can be guaranteed, and some data evaluation standards of the film itself are unified, so when choosing solar film, we need to pay attention to several important indicators of solar film:

Light transmittance, thermal insulation rate, ultraviolet blocking rate, film hardness and the professionalism of the construction environment.

Summary. Dear, I'm glad to answer your <>

The difference between the thickness of the explosion-proof film is as follows: the advantages of the thick film: the explosion-proof film is good, and the film is not easy to be destroyed.

Disadvantages: It is too thick and easy to be scratched by the window, which affects the appearance and vision. And in the later use process, the probability of delamination and degumming will also be greater.

Advantages of the film: it is not easy to be scratched by the window, the refraction and scattering of light through the thin film are not strong, and the line of sight can be clearer. Cons:

If the thin film wants to have good performance, then the requirements for the film making process are very high. If it is too thin, it is not very explosion-proof, and the film is too thin, and the inner heat insulation coating is easy to be damaged. <>
