Is it necessary to apply a car wrap on a car worth around 100,000 yuan?

Cars have become daily consumer goods for the public, and buying a car is only the first step for us to use a car. Later maintenance and upkeep are crucial to the later use of the car, and film is almost the first step after we buy a car. One important thing.

Car film is not to protect the glass. The purpose of car film can be divided into several aspects. The first is explosion-proof, the second is anti-ultraviolet, the third is anti-glare function, and the fourth is Privacy, etc. Because of this, many car owners pay more attention to car wraps. But is car wrapping really necessary? Especially is it necessary to apply a film on a car with a price tag of less than 100,000 yuan?

In response to such problems, first of all, we should correctly understand automobile glass. According to the law and the express regulations of the automobile industry, ordinary glass cannot be used in automobile glass due to safety considerations. There are only two types of automobile glass used in passenger cars sold on the market, one is tempered glass and the other is laminated glass.

Toughened glass is made by quenching ordinary glass to form a certain internal stress in the internal structure, thereby strengthening the strength of the glass. When broken by impact, the glass breaks into many small pieces without sharp edges. , but if nothing is connected, it will fall as a whole. In terms of use, it is mostly used for the windows on both sides of the car.

Laminated glass is laminated glass, which is an organic polymer intermediate film pasted between two or more layers of glass. It combines the strength and toughness of the film with the hardness of the glass, increasing the strength of the glass. Anti-breakage ability. When the glass is broken, the fragments will be stuck to the film, and the surface of the broken glass will remain clean and smooth. This is often referred to as explosion-proof. Currently, all front guards on the market use double-layer laminated glass.

Secondly, the UV resistance, heat insulation and privacy of glass have been solved in the original glass of many models today.

After the above explanation of the functions of glass, let’s re-understand the issue of car film. Through our understanding of glass, we can clearly understand that car film is not a necessary condition to solve user needs. So, let’s talk about anti-glare. Everyone knows that the lower the light transmittance, the better the anti-glare effect. However, such visual comfort does not mean safety. In fact, there are many reflection problems.

In the "Technical Conditions for Motor Vehicle Operation Safety" promulgated by the state on September 1, 2012, strict requirements are put forward for the transmittance of automobile windshield films. The visible light transmittance of the front windshield and glass other than the windshield used for the driver's viewing area should be greater than or equal to 70%. The light transmittance of ordinary glass is 80%, and the light transmittance of automobile glass is 75%-80%. After the film is applied, the light transmittance value is not optimistic. In fact, on domestic streets of all sizes, there are only a handful of vehicles with light transmittance that meet the standard. The key reasons are lax review and lack of attention from consumers.

According to what was mentioned above, car films not only enhance sealing and protect privacy, but also reduce the visible light transmittance of car windows and change the refractive index and reflectivity of car windows. Take the front windshield as an example. After the front windshield is filmed, the scene outside the window needs to be refracted four times when projected into the eyes. Long-term driving will not bring visual comfort, but visual fatigue, and it is not conducive to observing driving conditions. The dark film on the front side glass can indeed provide sun protection, but the visibility is extremely low when driving at night or on rainy days, which brings more safety risks than the gain.

Of course, it cannot be said that car film is meaningless. There must be a reason for its existence, but it is limited to car films that meet certain standards and can achieve safe quality and light transmission.

Whether or not to apply a film has a lot to do with demand. When applying film to a car, we should think about whether we need it instead of blindly following the trend. If our car really needs a car film, then we should also consider the light transmittance issue after the car film is applied. After all, safety is the most important thing for the car!

Zebra Jun has something to say: Through the above brief analysis, no matter what kind of price the car is, car wrapping is not a necessary condition to solve user needs.
