[China Glass Net] In front, you can see whether the building film has electrostatic attraction. The Shurejia building film has an electrostatic attraction because it contains more metal materials, so it is not easy to slide when rubbed.
Second, observe whether the plating layer is uniform or not. When purchasing a building film, the first thing to look at is whether it is evenly plated. If the plating is uniform, the quality is good, and the unevenness is not good.
Third, it is better to distinguish the advantages and disadvantages of the architectural film from the wear resistance. Generally speaking, the wear layer of the inferior film is not wear-resistant, and the genuine one has considerable abrasion resistance.
The correct way is that when we get the architectural film, we first distinguish its protective layer, then slightly rub it on the wear layer to see if it has a pattern. Those who have patterns are inferior.
The fourth method is the illumination analysis method. Because the effect of the thermal insulation film of the building film is different, the solar lamp with higher power can be used to illuminate the surface of the building film. Poor quality film insulation effect is poor, still feel hot through the film, and the quality of the film due to the quality, almost no heat can penetrate, so do not feel hot.
The latter method of selecting the architectural film brand is the clearing agent test method, which is more feasible. Contact with a building film, spray the carburetor cleaning agent on the film or rub on the ground, the color is the inferior film, which is known as the dye film.
