[China Glass Net] Car film, now looks like a standard car, it is standard than airbag EPS, no matter what car, you must film, not required by others, but the car owners themselves, the car running on the market More than 90% of the film is filmed, this is an indisputable fact.
If you want to make this clear, you must first understand some basic knowledge about automotive glass to have a conclusion.
There is no longer a problem with the use of a car film in the end of the car;
But everybody will always discuss:
Some riders said: The car film is like a heat insulation, sun protection, security, privacy protection, and no harm, why not?
There are also car friends who say: What kind of car film is attached, people in Europe and the United States have legislation to ban the film, the foreign sun is stronger than the domestic, I do not stick the car film, it is close to nature, then, the original glass has been separated Hot sun protection and other functions, why bother to paste the film more than one move?
Then, in the end, do not paste the car film, Xiaobian to straighten out, see if there is no reason.
First: side window and rear windshield, should not be film?
The side windows and rear windshields of most vehicles on the market are tempered glass, some are ordinary tempered glass, some are dark insulating glass, but some high-end front side windows use laminated glass.
Tempered glass is manufactured by high-temperature quenching method, which is characterized by extremely high hardness, but the explosion-proof performance will be relatively poor. When the tempered glass is severely impacted (notched), it will be broken into slag as a whole, which is obtuse-angled and small particles, and is not easy to injure people.
Ordinary tempered glass is only better in terms of glass strength, but it is relatively poor in sunscreen and heat insulation: the UV blocking rate is 1%, almost no UV rays, infrared blocking rate, and low heat insulation.
Dark insulating glass not only has better glass strength, but also has beautiful sunscreen and thermal insulation performance data: UV blocking rate can reach 99%, infrared blocking rate and thermal insulation can reach more than 49%.
Laminated glass is mainly used in the front side window glass of some high-end cars. Similar to the front windshield glass, it has excellent explosion-proof performance, as well as certain heat insulation and sun protection performance: the UV blocking rate can reach 99%, but the infrared blocking rate is separated. The heat will be lower.
Xiaobian Comments:
Tempered glass is almost non-explosive. Although the granules formed after cracking of the tempered glass are not dangerous, there are still hidden dangers, such as flying into the eyes. Dark insulating glass, tempered glass and laminated glass are very effective in preventing UV rays, but the thermal insulation performance is still slightly lacking.
Ordinary tempered glass and laminated glass also have the problem of not protecting privacy, so it is recommended to apply a film to protect the explosion-proof.
Second: the front windshield, is there a need to film?
For safety reasons, the current front windshield of the car basically uses laminated glass.
Laminated glass can be divided into ordinary laminated glass and coated glass.
Ordinary laminated glass consists of three layers, two layers of glass in the front and back, and a layer of glue in the middle of the glass. This kind of glass has good explosion-proof performance. If it is hit, the glass fragments will adhere to the middle layer of the gel in a spider web, and will not splash and hurt people. Moreover, this kind of glass itself has certain heat insulation and sun protection functions: the ultraviolet blocking rate can reach 99%, but the infrared blocking rate (heat insulation) will be relatively low, only about 20%.
Compared with ordinary laminated glass, coated glass has a layer of metal coating. This metal coating greatly improves the heat insulation and sun protection performance of the glass. It is equivalent to sticking a layer of car film: UV blocking rate can reach 99%, the infrared blocking rate (insulation) can also reach about 80%.
Coated glass used to be equipped with millions of luxury cars, but in fact, coated glass itself is not much more expensive than ordinary laminated glass. Now even if it is a civilian car, you can find matching coated glass on the market.
