pe protective film is constantly expanding according to market demand. However, some unscrupulous manufacturers supply low-quality, low-fake products, counterfeit, cheap and other counterfeit goods in order to make huge profits, and the rights of users cannot be protected. Therefore, Wuxi protective film reminds the majority of users: to choose a protective film, you must master some purchasing skills such as identifying materials, and do not be blinded by unscrupulous merchants because of price concessions, and cause unnecessary losses. First: It is difficult to recognize the transparency with the naked eye. It is best to use an optical instrument to measure it. There is also a simpler method, which is to cut a small piece of each type of protective film and place it in the middle of the computer desktop. , And then create a new blank WORD document on the computer, and check the whiteness of the blank WORD file in the area with and without the film on the computer or the area of u200bu200bthe different film (professional point of view is called brightness). Comparing separately, you can select the brightest material whose permeability is the best protective film. Second: Look at the haze 1. How do you see the haze of the PE protective film? First, check the haze when the monitor is turned off. The method is the same as the above. The smaller and the smaller the haze, the better the material. If you use a black test board in this method, it is easier to see the difference. 2. Another method is to turn on a fluorescent lamp in a slightly darkened room, tear off the protective film from the upper and lower release films, and hold it with your hands between the eyes and the light. You can carefully see if there is a layer of fog. Evenly distributed in the protective film, that is the culprit that affects the haze. The more serious the haze, the greater the haze and the worse the material, and vice versa. Third: Look at static electricity. Since the liquid crystal display is a sensitive device that is afraid of static electricity, the smaller the static electricity is, the better when attaching the protective film. The test method is to prepare the protective film to be tested (three-layer material or two-layer material), and smoke a cigarette. Light the cigarette ash on the desktop, or get some small paper scraps on the desktop, then tear off the top layer of the protective film (this step is for the 3 layers), and then tear off the protective film with the silicone layer. When removing this protective film, immediately move the used layer (silica gel surface) close to soot or paper dust to see if the protective film will adsorb these things on the silica gel layer of the protective film and whether the adsorption is strong. The stronger it is, the higher the static electricity generated by the material, the worse the material, and vice versa. Fourth: Look at anti-scratch 1. Whether the protective film is scratch-resistant and anti-scratch is the most concerned issue. At present, the anti-scratch materials on the market are basically the same (2-3H), and the performance is also good, only scratch-resistant and non-anti-scratch Scratch points. The test method is to use a pencil with a hardness of 3H and push it on the pe protective film with a force of 500G at a 45 degree angle for 10 times. If there is no scratch, it is considered to reach the 3H hardness requirement. 2. There is also a simple method, which is to use a slightly hard metal device or newly cut nails to scratch the surface of the pe protective film with the strength of a normal stylus. The simple method is to use a slightly hard metal device or new cut The nails are scratched on the surface of the material with the strength of a normal stylus. If it is very easy to scratch, it is deemed not to be scratch-resistant, and if it is not scratched, it can be determined that it has a scratch-resistant function. Fifth: Anti-fingerprint In recent years, more and more products have larger and larger screen sizes, and more and more smartphones are equipped with capacitive screens (touching with fingers is different from the old-fashioned resistive screens, which need to be drawn with a pen) For the application of pe protective film, there is an increasing need for anti-fingerprint function. For the purchase of protective film, users not only need to understand the relevant purchase skills, but also shop around in everything, and judge the choice based on the price, service, and the manufacturer's qualifications, strength, and customer evaluation.
