Some old drivers said that the film sent by the 4S store must not be used. It's a super pit. It's better not to use it. Is it true? Why do some people wrinkle and fade in a few years when they buy a good ceramic film. What causes the film to be scrapped in advance? Some people say it's too troublesome to put the film in the store. Can you put it on yourself? In fact, car glass film is very similar to eating puffer fish. If you buy puffer fish through regular channels and exquisite practices, you can taste fresh. If there is something wrong with the channel and practice, it will be poisoned.
Car glass film, you bought the right film. Master, the construction process is standardized. It can really insulate heat and prevent ultraviolet rays. If something goes wrong, it will affect driving safety.
What should I pay attention to for the film? Let's talk about it today. What films do you need to put on the car? First of all, you have to know which pieces of glass you need to put on. Everyone has different needs. You don't have to put on all the car stickers. The most recommended sticker for the front bumper is the front window glass, because most of the light comes from these glasses. If you often sit in the back, you can also put film on the rear window. Many cars have GPS and heating wires on the rear windshield, which is difficult to construct. If you are not a professional master, you are not recommended to paste them. Because bad pasting will not only affect the signal, but also easily blister.
If your sunroof cannot be opened, you can also apply film. If the skylight can be opened, the construction will be inconvenient. At the same time, such skylight itself has the functions of heat insulation and UV protection, and the film cost performance is not high.
How to choose different kinds of films? Now the films are mainly divided into dyeing film, ordinary metal film and magnetron sputtering process film. Dyeing film is not recommended. It's almost useless. If the budget is limited, buy ordinary metal film, but the service life of metal film is relatively short, and there are still problems such as blocking signals. Magnetron sputtering process is recommended. Ceramic film and composite metal film belong to this category. Compared with ordinary metal film, it performs better in terms of service life, light transmittance and heat insulation, and will not block the signal in the car. The price will be relatively expensive.
What parameters should you pay attention to when buying a membrane? The parameters of the same type of membrane are different, and the actual effect will be very different. Ask clearly before buying. First of all, the most important thing is the light transmittance. According to relevant national standards, the light transmittance of the glass of the front block and the rear-view mirror should be greater than 70% whether it is coated or not, otherwise it will not pass the annual inspection, and it will also affect the driving safety. The transmittance of the glass itself is not 100%, so the transmittance of the film is better than 75%. The light transmittance of the rear window glass film can be ignored. If you want to protect the privacy of the rear row, it's OK to use a dark film.
Then ultraviolet barrier. At present, for many cars of class 100000 or above, the front block can isolate more than 80% of ultraviolet rays, so the ultraviolet isolation rate of the film is better than 85%.
Then heat insulation. Because the isolation rate of car glass from solar energy is only 20%, the heat insulation of film is very important. Otherwise, the air conditioner will still be hot in summer. Generally, the front bumper film is qualified even if the total solar energy isolation rate is greater than 40%.
How to simply judge the quality of membrane? Some fake membrane parameters may be imaginary, so it is necessary to make a simple judgment. You can smell the film by yourself. If it's pungent, it's probably inferior film. Other parameters need to be measured with instruments.
What kind of weather film is best? It's best to choose a suitable weather, such as cloudy. When the weather is particularly hot or cold, it is easy to cause the film to shrink or expand excessively, affecting the effect after molding.
