The service life of an automobile film is closely related to its manufacturing process. The service life of good and poor is more than ten times different. Some can be used for 1 ~ 2 years, and some can even be used for 10 years. So, what is the service life of automobile film and how long can the automobile be used in general?
1. The dye film can be used for one year
The dyeing process film can only be used for one year and is easy to fade. The inferior automobile film is generally a dyeing film. The pigment is directly coated on the surface of the substrate film or on the glue. The quality is not very good, and it is easy to fade. It's like painting directly on paper with paint. It's ok if you look at it. It melts after a few drops of paint. - I'm confused. Therefore, even if it is used under normal circumstances, it is almost a year. If it is bitten with teeth, even a part of it can see very obvious color changes. The role of dyeing film is relatively limited, even affecting driving safety. The role of this kind of film is also relatively limited. Most of it is a dark translucent plastic paper, which has no heat insulation and explosion resistance.
How long can a general car film be used
2. 2 ~ 3 years for vacuum evaporated automobile film
Then, for the film one level higher than the dyeing film, the vacuum evaporation technology is used. At the time of making this kind of film, it will melt and evaporate the metal at high temperature, so that the metal atoms are evenly attached to the substrate film with the steam. To put it simply, it is like boiling water in a pot, then covering the pot with plastic film to collect steam. Because the metal needs to be boiled like boiling water, the metal can be plated on the substrate film by steam. Therefore, such films can only use some metals with low melting point, such as aluminum, which has great restrictions on materials. The service life is generally 2-3 years, there is also the problem of fading, and the evaporated atoms only float on the substrate film by steam. It feels like the cake is ready and you sprinkle a little fruit and chocolate powder on it. It can only ensure uniformity, and the adhesion is relatively general. Under normal circumstances, after its service life of 2 to 3 years, it will also have a very obvious fading problem.
3. The magnetron sputtering process can be used for 5 ~ 10 years
At present, the best films on the market use magnetron sputtering technology, such as multilayer composite metal or ceramic films sold on the market. Magnetron sputtering is a new technology that allows high-speed electric ions to strike various metal or ceramic targets in a low-pressure inert gas environment and sputter the targets onto the substrate film. If the evaporation technology just mentioned is to burn the metal, it will be self-healing Magnetron sputtering technology is equivalent to throwing a stone into the water, so that the water droplets splash onto the substrate film quickly. Compared with evaporation technology, the material adhesion is better. Compared with evaporation technology, the so-called splashed water droplets in magnetron sputtering technology carry higher energy, usually 100 times that of evaporation technology.
The adhesion of such ceramics and other materials plated is better. If it is evaporation technology, the cake is sprinkled with chocolate powder. Magnetron sputtering technology is to insert a piece of chocolate directly into the cake, and then knead the cake into a ball to turn it into a chocolate cake. The service life is more than ten years and it is not easy to fade. Then the service life of the film made by this technology is longer It is generally more than ten years, and it is not easy to fade.
