How to buy PET electrostatic film correctly
Apr 22, 2023
The electrostatic adsorption method adopts the principle of physics. When the protective film is in contact with the LCD screen, the pressure in the air between the protective film and the LCD screen becomes smaller, making the atmospheric pressure stronger than the air pressure between the screen and the film. produce adsorption capacity.
The electrostatic film is not only easy to stick but also easy to tear off. When you buy a screen protector, you should not only consider the scratch resistance of the film, but also pay attention to the adsorption property, not electrostatic adsorption.
The electrostatic adsorption screen protectors sold on the market are precisely static electricity + silica gel ion adsorption. The adsorption capacity of the silica gel layer has a great influence on the adsorption performance of the film. The electrostatic adsorption screen protectors of different manufacturers have different technical levels due to the different silica gel layers. The adsorption capacity is also very different, so it is also an electrostatic adsorption screen protector, but the service life of the screen film of different brands is different due to the difference in adsorption.
