Misunderstanding 1: front windshield can't be pasted on car

常常看到一些兄弟为自个的爱车贴膜时，只贴车身，而前风挡却不贴，问其缘由，说是怕影响视野。本来影响视野的都是些劣质膜，并非一切的隔热膜都影响视野的，交通部有有关条例，轿车前挡透光率不能低于70%，司机位两侧窗透光率不能低于50%。也即是说，能到达这个需求的隔热膜都能够贴在车窗上。一起，前挡膜关于轿车隔热来讲是主要的，由于前风挡是倾斜度很高的，来自太阳辐射的热量90%是经过前挡进入的，并且，轿车的座椅，仪表板，CD机，电子元件等都在车的前排，更主要的是咱们开车时也暴露在了阳光的爆晒之下！可见，为轿车前风挡玻璃装贴一款性能杰出的隔热膜对错常有必要的。

Often see some brothers for their own car film, only stick to the body, but not the front windshield, ask the reason, said is afraid of affecting the vision. In the past, the poor quality films affect the vision, not all the heat insulation films affect the vision. According to the relevant regulations of the Ministry of communications of the people's Republic of China, the light transmittance of the front bumper of a car should not be less than 70%, and that of the windows on both sides of the driver's seat should not be less than 50%. That is to say, the heat insulation film that can meet this demand can be attached to the window. At the same time, the front windshield film is the main heat insulation of the car. Because the front windshield is highly inclined, 90% of the heat from solar radiation enters through the front bumper. Moreover, the car seats, dashboard, CD player, electronic components, etc. are all in the front of the car. What's more, we are also exposed to the sun when driving! It can be seen that it is necessary to install a heat insulation film with outstanding performance for the front windshield glass of a car.

误区二：贴了汽车贴膜车内会凉快？

Myth 2: will it be cool inside the car with a car sticker?

有些兄弟误以为，又或许遭到商家的误导，说是贴了膜会凉快，但是当车子在太阳下爆晒了好久，再去取车时却发现车内仍然非常炽热。这是为何呢？举个比方，一间混凝土造的房子，在太阳爆晒下能够说它的墙面的隔绝了太阳光，但假如不开空调相同会炽热无 比，这个道理用到车上是相同的。由于热量的传递方式分为传导(比方握手感觉到冰凉或温暖)、对流(比方站在门口可感到里面空调的凉快)、辐射(比方太阳晒在肌肤上的火热)，为何要贴膜呢？由于空调仅处理了热量的传导和对流，但关于太阳的辐射却力不从心，这也是咱们为何穿黑衣裤驾车格外热的缘由。而车子停在太阳下爆晒，车顶的铁皮会不断传导热量，通风口不断对流热量，还有没有被隔绝的辐射热量也连绵不断的透到车里，车内滚烫是当然的。处理这个疑问的办法即是把太阳停在阴凉处，别的，起步前先把车窗降下让车内热量散发，然后再开空调，那么车内温度下降的时刻就会短的多了。所以说贴膜并不能令车内凉快，而是隔绝了太阳辐射的热量，然后减轻空调的负荷，推迟轿车内饰的老化。

Some brothers mistakenly thought, or were misled by businesses, that it would be cool to put a film on it. But when the car had been exposed to the sun for a long time, they found that the car was still very hot. Why? For example, a house made of concrete can be said to be insulated from the sun's light when it is exposed to the sun. However, if the air conditioner is not turned on, it will be extremely hot. This principle is applied to the car. As the heat transfer mode is divided into conduction (for example, feeling cold or warm when shaking hands), convection (for example, standing at the door of a shopping mall can feel the cool of the air conditioner inside), and radiation (such as the hot sun on the skin), why should we apply the film? Because the air conditioning only deals with heat conduction and convection, but the sun's radiation is not enough, which is why we wear black clothes and drive particularly hot. When the car is parked in the sun and exposed to the sun, the iron sheet on the roof will continue to conduct heat, the vent will continuously convection heat, and the radiation heat that is not isolated will continue to penetrate into the car. It is of course that the car is boiling hot. The way to deal with this problem is to park the sun in the shade. In addition, before starting, lower the window to let out the heat in the car, and then turn on the air conditioner, so that the time when the temperature in the car drops will be much shorter. Therefore, the film can not make the car cool, but isolated from the heat of solar radiation, and then reduce the load of air conditioning, delay the aging of car interior.
