Some old drivers said that the film sent by the 4S store must not be used. It's a super pit. It's better not to use it. Is it true? Why do some people wrinkle and fade in a few years when they buy a good ceramic film. What causes the film to be scrapped in advance? Some people say it's too troublesome to put the film in the store. Can you put it on yourself? In fact, car glass film is very similar to eating puffer fish. If you buy puffer fish through regular channels and exquisite practices, you can taste fresh. If there is something wrong with the channel and practice, it will be poisoned.

汽车玻璃贴膜，你买对了膜。师傅施工流程规范，确实能隔热，防紫外线。如果中间出了问题，反而会影响行车。

Car glass film, you bought the right film. Master, the construction process is standardized. It can really insulate heat and prevent ultraviolet rays. If something goes wrong, it will affect driving safety.

那贴膜需要注意哪些事情，今天来说一下。车子都需要贴哪几块膜汽车贴膜，得清楚自己需要贴哪几块玻璃，每个人需求不一样，不一定非要全车贴。前挡贴，然后就是前窗玻璃，因为大部分光都是从这几块玻璃照进来的。要是你后排经常坐人，后窗也可以贴上膜。很多车子后挡玻璃上有GPS和加热丝，施工难度比较大，如果不是的师傅，不建议贴。因为贴不好不仅会影响信号，甚还容易起泡。

What should I pay attention to for the film? Let's talk about it today. What films do you need to put on the car? First of all, you have to know which pieces of glass you need to put on. Everyone has different needs. You don't have to put on all the car stickers. The most recommended sticker for the front bumper is the front window glass, because most of the light comes from these glasses. If you often sit in the back, you can also put film on the rear window. Many cars have GPS and heating wires on the rear windshield, which is difficult to construct. If you are not a professional master, you are not recommended to paste them. Because bad pasting will not only affect the signal, but also easily blister.

如果你的天窗是不能打开的那种，也可以贴膜。要是能打开的天窗，施工会不太方便，同时这样的天窗自身就带有隔热和防紫外线功能，贴膜性价比不高。

If your sunroof cannot be opened, you can also apply film. If the skylight can be opened, the construction will be inconvenient. At the same time, such skylight itself has the functions of heat insulation and UV protection, and the film cost performance is not high.

不同种类贴膜怎么选现在贴膜主要分为染色膜，普通金属膜，磁控溅射工艺贴膜。染色膜就不买了，几乎没什么用。预算有限就买普通金属膜，但是金属膜寿命相对较短，还存在遮挡信号等问题。是磁控溅射工艺贴膜，陶瓷膜和复合金属膜都属于这类。相比于普通金属膜，在寿命，透光率，隔热性等方面表现都要更好，也不会遮挡车内信号，相对会贵一些。

How to choose different kinds of films? Now the films are mainly divided into dyeing film, ordinary metal film and magnetron sputtering process film. Dyeing film is not recommended. It's almost useless. If the budget is limited, buy ordinary metal film, but the service life of metal film is relatively short, and there are still problems such as blocking signals. Magnetron sputtering process is recommended. Ceramic film and composite metal film belong to this category. Compared with ordinary metal film, it performs better in terms of service life, light transmittance and heat insulation, and will not block the signal in the car. The price will be relatively expensive.

买膜需要注意哪些参数同种类型的膜参数不一样，实际效果会相去甚远，买之前问清楚。重要的是透光率，根据相关标准，前挡及观看后视镜的玻璃不管贴没贴膜，透光率都要大于70%，否则年检过不了，而且还影响行车。玻璃本身透光率是没有100%的，所以膜的透光率大于75%。后排车窗玻璃膜可以不用考虑透光率，如果想保护后排隐私，用深色膜也没问题。

What parameters should you pay attention to when buying a membrane? The parameters of the same type of membrane are different, and the actual effect will be very different. Ask clearly before buying. First of all, the most important thing is the light transmittance. According to relevant national standards, the light transmittance of the glass of the front block and the rear-view mirror should be greater than 70% whether it is coated or not, otherwise it will not pass the annual inspection, and it will also affect the driving safety. The transmittance of the glass itself is not 100%, so the transmittance of the film is better than 75%. The light transmittance of the rear window glass film can be ignored. If you want to protect the privacy of the rear row, it's OK to use a dark film.

然后是紫外线阻隔。现在很多十万级以上的车子，前挡本来就能隔绝80%以上的紫外线，所以贴膜的紫外线隔绝率在85%以上。

Then ultraviolet barrier. At present, for many cars of class 100000 or above, the front block can isolate more than 80% of ultraviolet rays, so the ultraviolet isolation rate of the film is better than 85%.

接着隔热性，因为车玻璃对太阳能的隔绝率只有20%，所以贴膜的隔热性很重要，不然大夏天，空调怎么吹都还是热的。一般前挡贴膜，总的太阳能隔绝率大于40%就算比较合格了。

Then heat insulation. Because the isolation rate of car glass from solar energy is only 20%, the heat insulation of film is very important. Otherwise, the air conditioner will still be hot in summer. Generally, the front bumper film is qualified even if the total solar energy isolation rate is greater than 40%.

如何简单判断膜的质量有些假冒的膜参数可能是虚标的，所以要简单判断一下。你可以自己闻一闻膜的味道，如果很刺鼻，大概率是劣质膜。其他参数，就需要用仪器来测量了。

How to simply judge the quality of membrane? Some fake membrane parameters may be imaginary, so it is necessary to make a simple judgment. You can smell the film by yourself. If it's pungent, it's probably inferior film. Other parameters need to be measured with instruments.

怎样的天气贴膜贴膜挑个合适的天气，比如阴天。因为天气特别热，或者特别冷的时候，都容易导致贴膜收缩或者膨胀过度，影响成型之后的效果。

What kind of weather film is best? It's best to choose a suitable weather, such as cloudy. When the weather is particularly hot or cold, it is easy to cause the film to shrink or expand excessively, affecting the effect after molding.
