The 12 mil security film is again called a bulletproof security film. With the strengthening of security awareness in the national banking industry, a series of standards have been passed. 12 mil security film has become a major hot spot in the application of security film. What are the performance of 12 mil security film? What is the standard of 12 mil security film? Let's take a look at it with the editor of Guangdong Anke Technology.
1. Ultraviolet blocking rate of 12 mil security film
It refers to the percentage of incident sunlight (10-400 nm) that does not pass through the filmed glass. The UV blocking rate of general automotive films is only about 40%, while the 12 mil security film is filled with UV absorbers in a deep layer, and this index can be as high as 99%.
2. Visible light reflectivity of 12 mil security film
It refers to the percentage of the visible light in the incident sunlight that is reflected back by the filmed glass; that is, the ratio of the visible light (380-780nm) reflected by the glass surface to the total visible light incident on the glass surface. The 12 mil security film reflects visible light while also reflecting part of the heat, and maintains the privacy of the car. However, excessively high visible light reflectance will produce light pollution and affect the sight of surrounding vehicles. Therefore, the law stipulates that the visible light reflectance of the heat insulation film shall not exceed 10%.
3. Visible light transmittance of 12 mil security film
The percentage of visible light in sunlight that directly penetrates the filmed glass window; that is, the percentage of the visible light (380-780nm) that passes through the filmed glass and the total visible light that strikes the surface of the filmed glass. Too low light transmittance will hinder the driver’s sight (especially the front film). National traffic safety regulations require that the visible light transmittance of the car’s front film be above 70%, otherwise it will seriously affect driving safety.
4. Total solar barrier rate of 12 mil security film
It is the heat insulation rate, which refers to the percentage of the solar energy blocked by the filmed glass to the total incident solar energy. The 12 mil security film mainly acts as a barrier to heat insulation by effectively blocking the infrared rays in the sun.
5. The safety and explosion-proof performance of 12 mil security film
First of all, the thickness must be more than 0.0275mm, which is what we often call the 12 mil security film, so that the safety and explosion-proof performance can be guaranteed. The 12 mil security film can prevent 79 micro submachine guns from shooting without penetrating and without splashes, which shows that Reliable impact resistance.
The safety glass made of ordinary glass with a safety film has reliable safety performance, is low in price and can greatly reduce the weight of the glass. Use a special safety film to paste on a certain thickness of ordinary glass to make explosion-proof glass, which can effectively resist the shock wave generated by the explosion when it encounters explosion.
The 12 mil security film reduces direct damage and damage caused by splashing of glass fragments. It can also reduce the repair costs of the bombed facilities and facilities near the bombing center.
The above is the introduction of 12 mil security film compiled by the editor of Guangdong Anke Technology for everyone. Do you know the performance of 12 mil security film and the standard of 12 mil security film?
