Principle:
UV film is an optical film whose main function is to filter and absorb ultraviolet (UV) radiation. Ultraviolet films are usually composed of multilayer composite materials, including media and absorbents with specific optical properties. When ultraviolet radiation passes through the UV film, the absorbent in the film can absorb ultraviolet energy and convert it into heat energy, thus preventing or reducing the transmission of ultraviolet rays and protecting people and objects from ultraviolet rays.
Use:
UV film is widely used, mainly in the following aspects:
Protection: UV film can be attached to the surface of glass windows, car glasses, sunglasses and other objects to block the transmission of ultraviolet rays, protect human skin from ultraviolet rays and prolong the service life of objects.
Beautification: UV films can have different colors and patterns, which are used to decorate and beautify the glass surface and increase the visual attraction of buildings, vehicles and other objects.
Privacy protection: Some types of UV films have privacy protection function, which can reduce the transparency of glass and prevent outsiders from peeping.
Temperature adjustment: UV film can also play a certain role in temperature adjustment, preventing ultraviolet radiation from entering the room and reducing indoor temperature rise.
The use of UV film includes directly sticking to the surface of the object or coating with professional coating equipment. When using UV film, we should pay attention to the selection of suitable film material and thickness and correct installation method to ensure its performance and effect.
