How to choose the glass stick membrane Sunscreen film: 1. From the abrasion resistance, it can be divided into low abrasion resistant coating layer, wear-resistant layer and not wear-resisting film. So after we get a piece of architectural membrane, the first is to distinguish its protective layer, and then rub it on the wear-resistant layer to see if it will produce pattern. If there is the decorative pattern, it is the low level; If there isn't the decorative pattern, it is the middle or high level film. 2. To see whether there is electrostatic attraction, due to the low membrane uses a little metal materials. So when it is being rubbed, it will slide from left to right; but to the high-end film, it has a kind of electrostatic attraction due to it with a lot of metal materials, and it is not sliding when rubbing. 3. The first is to see whether the plating layer is uniform, pick up a piece of building film to see whether it is uniform. If it is even, it is the good quality film. If it is uneven, it is the low quality film. 4. According to the analysis, because the heat insulation effect of different grades of film solar is not the same, so we adopt the high power lamp (500W--700W) to irradiate on the surface of the membrane. If the insulation effect of the low-grade membrane is poor, the hot will be felt even across the film. But for the high-end film, there is hardly any calorie that can penetrate it, so the hot will not be felt across the membrane. 5. The carburetor cleaning agent test method is to make the floor friction or the oil cleaning agent with a piece of film (also known as "cleaning agent") spray on the membrane. The fading inferior film is usually said tinted film. The film not fading is the high-end film, also known as the film of primary color. In summary, the building film with high transmittance and high thermal insulation is the high-grade film.
To choose the glass stick membrane Sunscreen film: 1. The thickness of the film itself, the thicker of the film, the higher of its explosion-proof ability! 2 To inquire the merchant about the level of the glue used by the explosion-proof membrane. 3 To emphasis the quality of the construction and the quality time of the merchant! (degumming, cracking, curling, mildew)
