现在市场上膜的种类繁多，济南量子膜告诉您怎么样才能知道膜的品质到底是不是真如经销商们说的那么好呢？济南量子膜告诉您从以下几个方面来看：

Now there are many kinds of films on the market, Jinan quantum film tells you how to know whether the quality of the film is really as good as the dealers say? Jinan quantum film tells you from the following aspects:

1.清晰性能：是汽车膜主要的性能，不论膜的颜色有多深，在夜间倒车时，从后视镜和后风档看60米以内的物体，应当视野清晰而决不模糊，劣质膜拿起来看，会有雾朦朦的感觉。

1. Clear performance: it is the most important performance of automobile film. No matter how dark the film is, when reversing at night, you should see objects within 60 meters from the rearview mirror and the rear windshield, and the vision should be clear and never blurred. If you take up the inferior film, you will feel foggy.

2．保质期：好多太阳膜的保质期为5～12年。

2. Shelf life: the shelf life of many solar films is 5-12 years.

3、防暴性：当膜片满足防暴要求时，越薄越好，膜片越薄，清晰度越高。

3. Riot resistance: when the diaphragm meets the riot requirements, the thinner the better, the thinner the diaphragm, the higher the definition.

4．颜色：高质量的膜颜色在膜片中，是一种高科技，永不变色。也可以在地上摩擦或将化油器清洗剂喷在膜上，掉色的为劣质膜，也就是通常所说的染色膜，不掉色的则为膜，也就是原色膜。

4. Color: high quality film color in the film, is a high-tech, never change color. It can also be rubbed on the ground or sprayed on the film with carburetor cleaning agent. The discolored film is inferior film, which is commonly known as dyeing film, while the non discolored film is superior film, which is primary film.

5．耐磨性：低档膜耐磨层不耐磨，而高档膜则有相当的抗磨性。所以，我们拿到一块太阳膜，区分清它的保护层后，只要在耐磨层上磨擦几下，看它是否有花纹产生。有花纹者为低档膜，无花纹者为中高档膜。

5. Wear resistance: the low-grade film wear-resistant layer is not wear-resistant, while the high-grade film has considerable wear resistance. So, after we get a piece of solar film and distinguish its protective layer, we just need to rub it on the wear-resistant layer a few times to see if it has patterns. Those with patterns are low-grade films, and those without patterns are medium and high-grade films.

6．是否有静电吸引力：由于低档膜中所用金属材料甚少，所以当磨擦低档膜时，它会左右滑动；而高档膜由于含金属材料较多，它具有一种静电吸引力，因此在磨擦时不滑动。

6. Whether there is electrostatic attraction: because there are few metal materials used in the low-grade film, it will slide left and right when rubbing the low-grade film; while the high-grade film has a kind of electrostatic attraction because it contains more metal materials, so it will not slide when rubbing.

7．胶与颗粒泡：胶越薄越好。因为胶会老化，胶层越厚老化越快，高质量膜的胶层都极薄，是强力压敏胶。胶层厚了，贴膜时能将尘埃压进胶里去，所以颗粒泡并不明显。高质量膜的胶层很薄，颗粒泡就比较明显。

7. Glue and granule bubble: the thinner the glue, the better. Because the adhesive will age, the thicker the adhesive layer, the faster the aging. The adhesive layer of high quality film is extremely thin, which is a strong pressure sensitive adhesive. When the adhesive layer is thick, the dust can be pressed into the adhesive when the film is applied, so the particle bubbles are not obvious. The glue layer of high quality film is very thin, and the particle bubble is obvious.

8．看电镀层是否均匀：拿起一块太阳膜，观看它的电镀层是否均匀，均匀者为质量好的膜，不均匀者为不好的膜。

8. See if the electrodeposition is uniform: pick up a piece of solar film and see if its electrodeposition is uniform. The uniform one is a good one, and the uneven one is a bad one.

9．灯照分析法：因为不同档次的太阳膜隔热效果不一样，所以我们可采大功率的太阳灯（500-700W）照射在膜的表面。如果是低档膜隔热效果差，隔着膜也会感到很热，而高档膜因为几乎没有什么热量可穿透它，故隔着膜不觉得热。

9. Light analysis method: because the heat insulation effect of different grades of solar film is different, we can use high-power solar lamp (500-700w) to irradiate the surface of the film. If the heat insulation effect of the low-grade film is poor, it will feel very hot through the film, while the high-grade film does not feel hot through the film because there is almost no heat to penetrate it.

10．全车整贴：这是防爆膜的基本性能，前后风档绝不允许裁条分贴！

10. Whole car sticking: This is the most basic performance of the explosion-proof membrane, and the front and rear windshields are not allowed to be cut and pasted separately!
