I believe everyone is quite familiar with 3M. During the recent epidemic, N95 masks produced by 3M became everyone's choice. Masks are just the tip of the iceberg of 3M's many product lines, from enterprise consumption to personal consumption, among which the automobile industry is also one of the important business sectors of 3M. Among them, thermal insulation film and body film are the fist products of 3M in the automotive field. As early as 1966, 3M obtained the world's first patent for thermal insulation film. Up to now, it has a number of patented technologies for thermal insulation films and professional technologies in the field of optical technology. On average, three new thermal insulation films are introduced every year, and various patented technologies make thermal insulation films have different unique functions. Therefore, 3M can be said to be the originator brand of automobile thermal insulation film.
Many friends have asked me why after the films presented by the 4S shop were posted, the radio stations turned into dregs and no radio stations could receive them. I often drop the line, and sometimes I can't even send WeChat. And GPS navigation can't locate, ETC often can't read cards. Don't even think about it There must be something wrong with the heat insulation film.
Thermal insulation film can be divided into metal film and non-metal film, in which metal film is vacuum plated with elements such as iron, aluminum, nickel and silver on the basis of colorless original film, and the purpose of thermal insulation is achieved through reflection. Obviously, this way is the fundamental reason that affects the reception of signals by electronic equipment in the car. The car covered with metal film is equivalent to an iron cage, and all kinds of signals can't get in or out, which greatly affects the daily use experience of electronic equipment. The key point is that the mobile phone will automatically emit larger radiation power when the signal is weak, which will further increase the electromagnetic radiation and endanger the health of the occupants in the car. Obviously, the slag film that shields the signal is not recommended.
This time, the 3M high-end nano-ceramic heat insulation film "Mu Color Series" adopted the innovative technology of 3M high-end nano-ceramics. Advanced ceramic materials are more resistant to high temperature, strong thermal insulation, chemical resistance, wear and corrosion, and high strength. A typical application of 3M ceramic technology is the thermal insulation coating on the surface of the space shuttle, which provides protection for the space shuttle in the case of extreme high temperature caused by severe friction with the atmosphere.
It is precisely because of the use of nano-ceramic technology that the 3M high-end nano-ceramic thermal insulation film "Mu Se Series" does not contain any metal materials, which means it will not interfere with and shield signals. People in the car can broadcast live videos, make long-distance calls and listen to the radio. In the car, at the same time, the 4G and 5G communication equipment in the car can work normally and quickly pass through the ETC lane and GPS. In other words, the 3M high-end nano-ceramic thermal insulation film "Mu Se Series" will not cause the harm of electromagnetic radiation due to the signal gain brought by signal radiation.
Of course, the basic characteristics of 3M high-end nano-ceramic thermal insulation film "Mu Se Series" are certainly no problem. You know, the sunscreen we contact every day, which is the highest SPF50, can block 98% ultraviolet rays. Its ultraviolet blocking rate reaches 99.9%, which is equivalent to SPF 1000. At the same time, it can also isolate up to 90% infrared (900- 100nm) line heat, that is, the total solar thermal insulation rate is as high as 60%. In addition, there are four levels of light transmittance, 19%, 3 1%, 45% and 78%, to ensure the privacy of your car.
The 3M high-end nano-ceramic heat insulation film "Muse Series" not only performs well in ultraviolet protection and heat insulation, but also is made of nonmetallic materials, which can ensure all electronic equipment in the car to receive and send signals smoothly and avoid electromagnetic radiation caused by unnecessary gain.
However, a professional car film shop should have a professional construction environment, construction tools and perfect construction technology. Today, I will reveal the whole process of standard membrane construction operation for everyone. The selected car film is a new series of ceramic heat insulation film of 3M. Let's go and see what happens. Put it on? Your car.

In order to further understand the "Mu Se Series" of 3M high-end nano-ceramic thermal insulation film objectively, we use professional instruments such as light transmission tester and thermal insulation film temperature tester to test the ultraviolet isolation, infrared isolation, visible light and thermal insulation of 3M high-end nano-ceramic thermal insulation film, so that it can speak with data!
Light transmittance test
We record the values of ultraviolet, infrared and light transmittance through an optical transmission tester. The test results show that "Mu Se Series", a 3M high-end nano-ceramic thermal insulation film, has an ultraviolet blocking rate as high as 100%, an infrared blocking rate as high as 89.8% and a visible light transmittance of 55.8%, while the infrared blocking rate of ordinary car film is only about 2 1.8%.
Ultraviolet test
The data obtained only by optical detection instruments is not enough. We also found ultraviolet sensitive test paper to test. By light irradiation, ordinary car film and direct irradiation will leave traces on the test paper, while the 3M high-end nano-ceramic heat insulation film "Mu Se Series" has no traces.
Thermal insulation test
Through a professional thermal insulation film temperature tester, one side of the film was simulated to heat up, and the temperature changes of "Mu Se Series" of ordinary thermal insulation film and 3M high-end nano-ceramic thermal insulation film were compared respectively. After heating for a few minutes, it was found that the temperature rise of the 3M high-end nano-ceramic thermal insulation film "Mu Se Series" was very slow, and the temperature change was only 65438 0.5℃, while the temperature of ordinary thermal insulation film rose sharply, reaching 8℃. Therefore, the test results show that the 3M high-end nano-ceramic thermal insulation film "Mu Se Series" has excellent thermal insulation performance.
Intuitive contrast experience test
Through objective data test, it is obviously impossible to empathize. So, we found two cars of the same model, one with 3M color film and the other with ordinary model, and tested the signals in the cars respectively. The electric field value is 20 1V/M, and the magnetic field value is also kept at 0.37 when making real-time calls in the car with 3M ceramic insulation film, which is consistent with the smooth signal when making calls outside the car. This shows that 3M's new color insulating film will not block the signal, and you can leave it on at any time.
Test whether the cell phone /ETC signal shields the isolation experience.
This link will be tested in four intuitive ways, mainly to judge the signal gain of the mobile phone, the Bluetooth connection between the mobile phone and the car outside the car, the download speed of the 5G mobile phone and the passage of ETC.
After the in-car phone call, Bluetooth connection outside the car, 5G signal and download speed were tested, the cell phone signal was blocked. Especially when making a phone call, the mobile phone automatically increases the transmission power, which leads to the increase of the overall electric field and magnetic field, which obviously brings invisible harm to the human body. The 3M high-end nano-ceramic thermal insulation film "Mu Se Series" performs better, and it is difficult to detect any signal obstacle in the three projects, with clear call and fast Bluetooth connection speed.
As for the ETC signal test, we personally drove the car to the toll booth to test. It is found that the car with 3M high-end nano-ceramic thermal insulation film "Mu Se Series" has a very fast recognition speed when passing through ETC gate, and it has been successfully recognized after many passes. However, it is very easy for cars with ordinary heat insulation film to identify mistakes when passing through ETC gates, or they cannot read the information of ETC equipment. The number of successful tests is not much, and the success rate is even less than 50%. Obviously, ETC signal is isolated and shielded by ordinary thermal insulation film.
Four empirical tests of top thermal insulation performance
We put two test cars in the sun for half an hour at the same time (one covered with 3M color film and the other with ordinary film), and then put the ice cream in the center console for half an hour. Judging the heat insulation of heat insulation film by melting ice cream.
After the ice cream melting test, it is intuitively felt that the temperature rise in the car using 3M high-end nano-ceramic thermal insulation film "Mu Se Series" is slower than that of ordinary thermal insulation film, which shows that the thermal insulation performance of 3M high-end nano-ceramic thermal insulation film "Mu Se Series" is better.
Anti-glare and breathable experience
Next, let's take a look at the anti-glare experience test. We parked two Tesla Model 3s at a distance of 3 meters, turned on the high beam to illuminate each other, and felt the glare suppression effect of the windshield insulation film before the experience.
As one of the landmarks of network celebrities in Guangzhou, Ersha Island in Guangzhou is also very colorful, just in line with our night clarity test. From the same point of view, test whether the exterior lighting effect seen by two cars in the car is clear and whether there are problems of reflection and glare.
The following was taken in my car, using 3M color car film. Look at the night view outside, it's really clear! It's unambiguous.
But when I sat in my friend's car and looked out, it was not so clear and I felt a little fuzzy. It looks fuzzy. He posted an ordinary car film.
After a round of experience and testing, I was deeply rooted by the 3M high-end nano-ceramic thermal insulation film "Mu Se Series". First of all, the advanced texture of Tesla Model 3 is further enhanced after the 3M high-end nano-ceramic thermal insulation film "Mu Se Series" is affixed, which has a noble and mysterious feeling. In addition, the dark design can also protect the privacy inside the car. Compared with ordinary thermal insulation film, 3M high-end nano-ceramic thermal insulation film "Mu Color Series" has better performance in heat insulation, ultraviolet isolation, anti-glare, night vision and energy consumption reduction. I especially like that it won't block any signals, and all kinds of electronic devices in the car can send and receive signals without obstacles, so that many embarrassing situations can be avoided. The most important thing is that there is no odor residue after pasting, which is more environmentally friendly.
