Inferior material
A friend who buys a car will find that the 4S shop will present a complete set of decorations when it leaves the car, including the car glass film, but the quality of the film is indeed uneven. “4S stores will sell hundreds of sets at a time, and the price is relatively low. Although they are also internationally renowned brands such as 3M and Weigu, the quality can be passed, but it is not the best. The effect of heat insulation and sun protection is also discounted.†Yang, the director of the City Zhiyin VIP car club, said. Most of these films are made of metal. "The metal film will naturally oxidize after a long period of sunlight, and the chemicals inside will slowly decompose. After a long time, it will enter the human body." There is also a metal film that stimulates people's attention. At night, the light shines on the metal film. It will be reflected in the eyes of the person, causing the driver's line of sight to be disturbed, resulting in a safety hazard during driving. Yang stressed.
In addition, according to the national standard "Safety Technical Conditions for Motor Vehicle Operation" (GB7258-2004), Article 11.6.4, the driver's cab must ensure the driver's front and side views, front windshield and glass outside the windshield. The visible light transmission for the driver's viewport portion is not allowed to be less than 70%. "But in fact, the visible light transmittance of the film in 4S shop is below 70%." Yang said, "At present, 90% of 4S stores are relatively inferior metal films, so it is not recommended to use the film provided by 4S shop."
Nano ceramic film is more reliable
"Compared with the quality defects of metal film, the film of nano-ceramic film material is more reliable." Yang said that the nano-ceramic film brand is widely used in high-tech fields such as navigation, construction and automobile market. Its material is metal-free, unlike metal films that oxidize, and have higher UV and heat insulation rates.
The important thing is that from a price perspective, the difference between the two is not very large. "For the Ford Focus film as an example, the top metal film is usually around 10,000 yuan, and the ordinary price is around 3,000 yuan to 5,000 yuan. If ordinary nano ceramic film is used, the price is around 3,000 yuan, and the whole car uses the top nanometer. Ceramic film, the price is about 10,000 yuan. The same price, but the nature is very different." Yang executive introduction. Once a customer came out of the 4S shop, I felt that the film was not insulated and the reflection was too high. The film on the car was torn off and replaced with a nano-ceramic car film.
The insulation effect is very different
Then, the thermal insulation effect of the ceramic film and the metal film is much different. Yang executive made an experiment to this reporter. He placed the thermometer in front of a 200W bulb and the thermometer showed the current temperature at 1600. The glass containing the metal film was then placed between the thermometer and the heat source, the data showed 460, and after replacing the metal film with the nano ceramic film, the data showed 153. This experiment shows the advantages of nano-ceramic car film in insulation.
When talking about how to put a car film on the car, Yang said, “In general, the front windshield is best attached to the top film, because 60% of the ordinary heat enters the car through the front windshield, and both sides The glass can be used with ordinary car film."
