How to buy PET electrostatic film correctly?

The electrostatic adsorption method is based on physical principles. When the protective film comes into contact with the LCD screen, the pressure in the air between the protective film and the LCD screen becomes smaller, which makes the atmospheric pressure stronger than the pressure of the air between the screen and the film. Generate adsorption capacity. The electrostatic film is not only easy to stick but also relatively easy to tear off. In addition to considering the scratch resistance of the film when buying a screen protector, you also need to pay attention to the adsorption. It is not just electrostatic adsorption. The electrostatic adsorption screen protector sold on the market is precisely electrostatic + silica gel ion adsorption. Silicone The adsorption capacity of the layer has a great impact on the adsorption performance of the film. The electrostatic adsorption screen protection films of different manufacturers also have very different adsorption capacities due to different technical levels. Therefore, they are also electrostatic adsorption screen protection films, but different brands of Screen films have different lifetimes due to differences in adsorption.
