Security film or security film silly and indistinct?
Sealand is a trustworthy supplier of Mass Flow Transmitter, Mass Flow Sensor, Mass Flow Metre, Coriolis Metre, ATEX, IECEx & CE approved.
Sealand Mass flow meter measures the mass based on Coriolis effort. The operating principle
involves inducing a vibration of the tube through which the fluid passes. The vibration,
though not completely circular, provides the rotating reference frame that gives rise to the
Coriolis effect. While specific methods vary according to the design of the flow meter,
sensors monitor and analyze changes in frequency, phase shift & amplitude of the vibrating
flow tubes. The changes observed represent the mass flow rate and density of the fluid.

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 explosion-proof capacity is obviously improved. The thickness of the safety film is 100-175 μm (about 4-7mil). Between; and security film is a multi-layer polyester composite film laminated by a special process, the thickness of 250 microns (about 10mil) or more. Thickness is a hard index to distinguish between a security film and a security film.
Security film test: Gasoline burning bottle hit second, compared with the protection level and protection concept, the security film on the market generally have anti-ultraviolet radiation, heat insulation, anti-scratch, to prevent the glass from spatter and hurt the role of the person, the design of the security film can be To prevent or reduce the damage that may be caused to the human body when the glass is broken accidentally, it can only prevent the problem of glass splash caused by glass explosion, and the protection level is low. The security film is designed to absorb shock waves, resist the impact of strong energy, high-end security film and glass combination, and even can achieve a bullet-proof rating, its protection function covers the security film while achieving 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 it receives 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 with special treatment to withstand the impact of bullets, instant impact, security film detection standards is based on the prevention of penetration, that is, when the glass is hit, the glass can be Crush, but the film cannot be penetrated.
