Jinan auto film is getting hot day by day. It is necessary to apply Jinan auto film whether it is hot summer or ice and snow winter. But just because the market is hot, it also gave birth to the fake market and harmed consumers.

就比如这济南汽车贴膜，看似挺简单的一个东西，你看，我们的手机和电脑都会贴，保护屏幕被划伤嘛，能看清屏幕，好的话，追求防辐射度，贴上就ok了。

For example, Jinan automobile film seems to be a very simple thing. You see, our mobile phones and computers will paste it to protect the screen from being scratched. If you can see the screen clearly, pursue radiation protection, and paste it.

但汽车的贴膜就有点复杂了，因为我们汽车经常会经历暴晒和高速行驶啊，选一个好的汽车贴膜，对行车安 全和车内人健康、隐私都是非常重要的。

But the car film is a little complicated, because our cars often experience exposure to the sun and high-speed driving. Choosing a good car film is very important to driving safety, the health and privacy of the people in the car.

那什么是好的汽车贴膜呢?有三个判断指标：隔热率、透光率、防紫外线率。

What is a good car film? There are three judgment indexes: heat insulation rate, light transmittance and anti ultraviolet rate.

好的隔热率可以在夏天保持车内不会有太高的温度，还可以更好的保持空调的制冷效果。

Good heat insulation rate can keep the temperature in the car not too high in summer, and can better maintain the cooling effect of the air conditioner.

但有些厂家靠增加颜色深度来隔热，颜色越深，隔热能力越强，可是会影响到它的透光率就会变低。

However, some manufacturers rely on increasing the color depth to heat insulation. The darker the color, the stronger the heat insulation ability, but it will affect its light transmittance and become lower.

隔热率高，同时透明率也高的膜呢，采用的技术会更，也是越高，我们的前挡风膜一般就是这样的。

Films with high heat insulation rate and high transparency rate will adopt more advanced technology and higher price. This is generally the case with our front windshield films.

前挡风良好的透视性对于司机行车非常重要，所以，大多数，对于前挡风的贴膜都有严格的规定，我们的规定是，要求前挡风的透视率不能低于70%，但并不是说，你买的贴膜的透视率是70%就合格了，因为我们的前挡风玻璃本身也是有个透光率的，用这个透光率再乘以汽车贴膜的透光率，不低于70%才是合格啊。

Good perspective of the front windshield is very important for drivers to drive. Therefore, most countries have strict regulations on the film of the front windshield. Our national regulations require that the perspective rate of the front windshield shall not be less than 70%, but it does not mean that the perspective rate of the film you buy is 70%, because our front windshield itself also has a light transmittance, Multiply this light transmittance by the light transmittance of the car film, and it is qualified if it is no less than 70%.

另外就是防紫外线率，其实目前啊，防紫外线技术比较成熟，大部分的车膜，无论高低，防紫外线率都能达到90%，基本都合格。

In addition, the anti ultraviolet rate. In fact, at present, the anti ultraviolet technology is relatively mature. Most of the car films, regardless of the price, can reach 90% of the anti ultraviolet rate, which is basically qualified.

所以，总结一下，我们选车膜的好坏主要还是看隔热率和透光率。

Therefore, to sum up, the quality of our choice of car film mainly depends on the heat insulation rate and light transmittance.

但是，我们知道了指标，也并不能说一定能不被坑。

However, when we know the indicators, we can not say that we will not be trapped.

比如，我们去贴膜店贴膜，商家告诉你，隔热率和透光率是多少多少，都合格，甚是告诉你说，这个膜是量子膜、龙膜这些的，可你是无法鉴别的。

For example, when we go to the film shop to apply the film, the merchant tells you that the heat insulation rate and light transmittance are qualified, and even tells you that the film is a brand of quantum film and Dragon film, but you can't identify it.

更别说我们去网上购买，商家的网店装修的漂亮一些、高大上一些，是很能唬住人的呀，稍不注意买到假货，你可能自己都不知道。

Not to mention that we buy online, the merchant's online shop is decorated more beautiful and tall, which can scare people. If you don't pay attention to buying fake goods, you may not know it.
