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、染色膜可以用一年

1. The dye film can be used for one year

染色工艺贴膜仅可以用一年，且易褪色。劣质的汽车贴膜，-般就是染色膜，直接把颜料涂在基材膜的表面，或者是胶上边，质量都不太好，而且容易褪色。就如同直接用颜料在纸上画画-样的，你看一下是还好，略微沾几滴水颜料就化开来了，-場糊涂了。所以说，就算正常情况下使用，一年差不多了，如果是用牙咬，甚被咬一部分都能看见非常明显的颜色变化。染色膜作用比较有限，甚影响行车安 全，这类膜的作用也比较有限，大部分就是一张深颜色的半透明塑料纸，也没隔热、抗爆能力。

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.

一般的汽车贴膜可以使用多长时间呢

2、真空蒸镀的汽车贴膜用2~3年

2. 2 ~ 3 years for vacuum evaporated automobile film

那么比染色膜高一级的贴膜，用的是真空蒸镀技术。这类贴膜在制作的那时候，它会把金属在高温下熔化蒸发，让金属原子随着蒸气均匀地附着在基材膜上边。比较简单的说，如同就是用锅烧水，再把塑料膜盖在锅上边，收集蒸汽。由于是需要像烧水-样把金属烧开，利用蒸汽才能把金属镀到基材膜上去。所以说，这类膜只能用一些熔点不太高的金属，例如说铝，它对材料的限 制是较为大的。使用寿命一般2-3年，也存在褪色问题，而且蒸发出来的原子，也仅仅是依靠蒸汽这么飘在基材膜上边的。就如同蛋糕已经做好了，你上边撒一点果粒、巧克力粉一样的这种感觉。它只能保证均匀，附着性是较为一般的，正常情况下使用寿命2到3年之后，也会“生较为非常明显的褪色问题。

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、磁控溅射工艺的汽车贴膜，可以用5~十年

3. The magnetron sputtering process can be used for 5 ~ 10 years

目前市面上好的贴膜，用的叫磁控溅射技术，比如说市面上卖的多层复合金属，或者是陶瓷膜。磁控溅射是在低压惰性气体的环境里面，让高速电离子撞击各种金属或者陶瓷的靶材，让靶材溅射到基材膜上面，这么一个新技假如说刚刚说的蒸镀技术是把金属烧开,自己飘上去的，磁控溅射技术就相当于拿石头用力丢到水里面,让水滴飞快的溅到基材膜上边去了。相比蒸镀技术，材料附着性更好相比蒸镀技术，磁控溅射技术里面的这所谓的溅开来的水滴，它携带的能量更高，通常是蒸镀技术的100倍。

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.

镀上去的这类陶瓷等等其它这类材料附着性就更好。如果是蒸镀技术蛋糕上边是撒巧克力粉的话。磁控溅射技术就是把一块巧克力直接插到蛋糕里面去了，再把蛋糕揉成-团，变成巧克力蛋糕。使用寿命也在十年以上,不易褪色那么用这类技术制作的贴膜，使用寿命一般是十年以上的，不容易褪颜色。

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.
