At present, there are many brands of glass film at home and abroad, but the variety of film materials on the market is also very rich. What is a security film? What is a security film and what is the difference between them? Overall, the difference between security film and security film is roughly threefold:
First, from the perspective of the structure and thickness of the material, the safety film is generally a single-layer material, while the safety film is a multi-layer film technology. The ability to resist explosion is obviously improved. The thickness of the safety film is 100-175 μm (about 4- Between 7mil) and the security film is a multi-layer polyester composite film laminated by a special process, with a thickness of 250 microns (about 10mil) or more. Thickness is a hard index to distinguish between a security film and a security film.
Secondly, compared with the protection level and the protection concept, the safety membranes on the market generally have anti-ultraviolet rays, heat insulation and scratches to prevent the glass from spattering and hurting people. The design of the safety membrane can prevent or reduce the accidental crushing of the glass. The damage that may be caused to the human body can only prevent the problem of glass splash caused by similar glass blew, and the protection level is low. The design of the security film can absorb explosion shock waves, resist the impact of strong energy, high-end security film and glass combination, and even can achieve the bullet-proof rating, and its protection function covers the safety film effect while reaching the security level.
Third, there is a clear difference between the safety film and the security film in terms of implementation standards. The standard that the safety film can generally meet is to prevent the glass from being broken. Most of these standards are to prevent “glass breakageâ€. The safety film is to prevent the window glass from being broken when subjected to low energy impact; if the glass breaks, its fragments are broken. Large areas still need to be adhered to the safety film to prevent the secondary damage caused by the falling of the glass. The security class explosion-proof membrane is generally treated to withstand the explosive impact of bomb explosions, bullets, etc. The security film detection standard is based on the prevention of penetration, that is, when the glass is hit, the glass can be It is crushed, but the film cannot be penetrated.
