After you buy a new car, whether it's for privacy or sunscreen, you can't do without the process of applying film. But everyone said that the window could not be opened for a few days after the film was applied. What's going on?

车玻璃在贴膜后，防晒膜需要一定的时间与玻璃完全吻合，如果在未完全吻合时升降玻璃，在防水护胶的摩擦帮助下，你的防晒膜很可能就被搓开了，或者给你搓起个角之类的也是非常磨人。

After the car glass is coated with the film, the sunscreen film needs a certain time to completely match with the glass. If you lift the glass when it is not completely matched, with the help of the friction of waterproof protective glue, your sunscreen film is likely to be rubbed open, or give you a corner, which is also very abrasive.

一般来说如果是夏天贴的膜3天之内不要开窗，如果是冬天就延长到，一周左右的时间为宜。所以说如果您是重度的幽闭恐惧症患者，还是等几天再开车吧，免得控制不住自己的小手。

Generally speaking, if the film is pasted in summer, do not open the window within 3 days. If it is winter, it should be extended to about a week. So if you are a severe claustrophobic, you'd better wait a few days before driving, so as not to lose control of your little hands.

告诉大家一个小秘密，大家尽量挑选天气温和一点的时候贴膜，如果当天妖风阵阵，昼夜温差特别大，咱就择日再战！下雨天也是可以贴膜的，反而还有好处，阴天和雨后空气湿度大，静电和灰层都是比较少的，是贴膜的好的时候。不要在灰层和恶劣环境贴膜，好的环境是无尘贴膜。阴天和下雨天水份挥发慢，需要多等1-2天才会干透。

Let's tell you a little secret. We try our best to stick the film when the weather is milder. If there are evil winds and the temperature difference between day and night is particularly large, we'll fight again on another day! The film can also be applied in rainy days. On the contrary, it is also beneficial. The air humidity is high in cloudy days and after rain, and there are relatively few static electricity and ash layers. It is a good time to apply the film. Do not apply the film in the ash layer and harsh environment. A good environment is a dust-free film. In cloudy and rainy days, water volatilizes slowly and needs to wait 1-2 more days to dry out.

汽车贴膜就是在车辆前后挡风玻璃、侧窗玻璃以及天窗上贴上一层薄膜状物体，而这层薄膜状物体也叫做太阳膜或者叫做隔热膜。它作用主要是阻挡紫外线、阻隔部分热量以及防止玻璃飞溅导致的伤人、防眩光等情况发生，同时根据太阳膜的单向透视性能，达到保护个人隐私的目的。此外，它也可以减少车内物品以及人员因紫外线照射造成的损伤，通过物理反光，降低车内温度，减少汽车空调的使用，从而降低油耗，节省一部分开支。

Automobile film is to stick a layer of thin-film objects on the front and rear windshield, side window glass and skylight of the vehicle, and this layer of thin-film objects is also called solar film or thermal insulation film. It is mainly used to block ultraviolet rays, block part of heat, prevent injury and glare caused by glass splash, and protect personal privacy according to the unidirectional perspective performance of the solar film. In addition, it can also reduce the damage caused by ultraviolet radiation to articles and personnel in the car, reduce the temperature in the car through physical reflection, and reduce the use of car air conditioner, so as to reduce fuel consumption and save some expenses.
