Self driving car selecting solar film technology
First of all, we want to look at the color of this solar film, currently most of the poor film on the market are directly added to the pigment of the viscose coating on the film surface for coloring. This viscose coloring method often produces the sun film will fade after exposure to the sun, fade seriously, and even make the original colored film back to transparent film. The high-quality solar film uses metal sputtering process, nickel, silver, titanium and other advanced metals are coated on high tension natural rubber film for coloring, in daily use will not appear fading, fading phenomenon. When the owner chooses, he can spray a little carburetor cleaner on the film to be tested, or pour a little gasoline on it, and scratch the film. At this time, the color of the quality film will not be crossed, while the inferior film will be very serious.
Second, the transparency of the solar film "no matter what kind of solar film, if affixed to the car will affect the clarity of the field of vision, then the best thermal insulation performance is also floating clouds. One of the most important properties of automotive solar film is clarity, no matter how dark the color of a qualified solar film, should have a considerable field of vision clarity, which is closely related to driving safety. Generally speaking, high-quality solar film can make even in rainy days, night driving personnel, can have a clear perspective; and poor quality paste film perspective, from the inside to see outside people have a hazy feeling.
Then it depends on how the film feels. One of the big differences between different quality films is their feel and wear resistance. High-quality solar film because of the production process, the surface has been hardened, so feel more smooth, texture, the surface after long-term use will not leave scratches, good wear resistance; and poor quality solar film is mostly ordinary color film, feel rough and thin and brittle, use soon It will leave scratches and wear resistance.
Also, we need to test the thermal insulation of solar panels. Experts pointed out that high-quality solar film insulation rate should reach more than 80%, three to four times higher than ordinary color film. On the contrary, most of the ordinary color film is only made from transparent film dyed by viscose, and the ability to block ultraviolet rays is poor. Under the sun exposure, it is easy to cause the aging and fading of the articles in the car, and it will also cause the skin of the people in the car. Hurt. Generally speaking, most of the regular automobile assembly shops are equipped with infrared insulation experience racks for car owners, high-quality solar film can make people feel the temperature difference before and after the film, and poor solar film before and after the film, people in the car feel stuffy. In addition, there is a simple way to identify the ability of the solar membrane to resist ultraviolet radiation: first put a RMB under the film, and then use the ultraviolet light of the checking pen to examine the paper money through the film. If the watermark on the paper money can not be displayed, it shows that the film can effectively block ultraviolet light, otherwise, it shows that the UV barrier ability of the film is poor.
Finally, we have to ask about its odor, because the sun film attached to the car, after the sun, the smell is often related to the car's health. High-quality laminating process is complex, high-tech content, and through health and safety testing before entering the market, even in the sun will not produce harmful volatile substances. The low-quality membrane is easy to manufacture and low-cost materials. It often volatilizes harmful substances such as formaldehyde and benzene in the process of use, which will cause serious harm to people's health after long-term use.
