How to see through the explosion proof film market fraud?

Method. First, the test pen inspection method. Take the film to the test pen and place a 100 RMB sheet under the film.

Because the banknote test pen is used to check the authenticity of the RMB by displaying the anti-counterfeiting mark through ultraviolet light. And put the film on the RMB, if the UV protection function is good, then the 100 yuan watermark on the RMB will not be displayed, otherwise, the UV protection ability of the film is not good.

Method. 2. Gasoline identification method. Pour a little gasoline over the membrane to be tested and scratch it with your fingernails.

If the color of the film is crossed out all of a sudden, it means that the film is just a little color added to the film paper, which is far from the effect of the film, and no matter how the really good film is scratched, it will only fall off the glue and will not fade.

Method. 3. Metal layer identification method. Good films contain metal layers, you can compare high-quality films with inferior films, hold the film in your hands, and gently flick the film with your fingers, because the high-quality film contains metal layers, so the sound is generally very crisp, and the sound of the inferior film is muffled, at this time the owner friend has to carefully inspect.

The brittleness of glass is very large, and it is very afraid of the force per unit area. The function of the explosion-proof film is to increase the overall toughness, and when the glass is broken, the good toughness of the explosion-proof film can connect the broken glass into a whole. The bulletproof glass used by the bank is actually an ordinary three-layer glass with 2 layers of explosion-proof film, and it is required that the bullet of the specified caliber cannot pass through the second layer of explosion-proof film after being hit, so it plays a bulletproof role.

Glass will still break.

The automobile explosion-proof film has three functions: one is explosion-proof, when the glass is hit by external force, it will not fly horizontally, but will break into a whole and be attached to the film, which will not hurt people; The second function is to block the direct ultraviolet rays of the sun and protect from the sun; The third function is to block the direct and reflection of the high beams of the car behind when driving at night, and at the same time, it also has a certain blocking effect on the lights around the car, so that the driver can drive with peace of mind. Of course, choose a color with the right amount of depth, not too dark, not too light.

It's too dark to see what's going on; Too light doesn't work.

Hello. Like glass curtain walls, shower rooms at home, etc., it is necessary to use explosion-proof film, which can increase the strength of the glass, even if the glass bursts, it can also fix the fragments in place, reduce the occurrence of accidents, and also strive for more time for the owner to replace the glass.

Let's take a look at the explosion-proof film first

1. Polyester substrate (PET), the main material of glass explosion-proof film, is a strong and high-toughness elastic substrate, and the metal has good ductility and toughness, which can effectively offset the impact of decomposition.

2. It makes full use of the adhesive layer and metal plating layer to improve the rigidity of the explosion-proof glass film and decompose the impact force.

3. The explosion-proof film is attached to the inside of the glass, and the broken glass will be fixed in place to reduce personal injury, and the safety anti-theft film can slow down and prevent thieves from burglarizing and protect property safety. There is also a special explosion-proof film for external sticking.

4. The glass explosion-proof film is professionally installed to form an "invisible tough barrier" on the glass.

Guangzhou Shengyi.

Useful. There are several main benefits of the film: leakage.

Beneficial for regulating temperature.

In the hot summer weather, the film can insulate the heat and save energy for the air conditioner. In winter, when the weather is cold and wet, the film can reduce energy loss and maintain the temperature in the car.

Prevent harmful light from ingress

After the film, it can effectively block ultraviolet rays that are harmful to the human body, and avoid sunburn, cancer or various diseases caused by excessive exposure to ultraviolet rays.

Reduce glare After the film, it can reduce the glare caused by glass light, so that you can drive with more protection.

Prevent glass splashing.

After the film, the safety base of the film can prevent the glass from splashing, so as to avoid accidental injury and ensure safety.

Automatically adjust the light of He Laozi.

After the film is applied, the film can play a role in automatically adjusting the light in the car, which is suitable for any change in the sky and ensures a clear vision.

Ultraviolet insulation extends the life of the interior.

How to identify high- and low-grade automotive explosion-proof films:

1.Brands, Trademarks, Trademarks.

R-Registered Trademark, TM-Willjet International Convention Trademark.

2.Where is the place of origin?

3.Size, packaging.

International standard 60 x100

4.**Letter of Authorization.

5.Whether the performance indicators are comprehensive and scientific.

6.Whether the clarity is dazzling, etc.

7.Color, fade or not, pure, elegant, coordinated, pleasing to the eye.

8.Film method: whole paste, sub-paste.

9.Granular vesicles.

10.Shelf life (imported from the United States, the general warranty is 10 years, and the IR ceramic series of Johnson & Johnson is a lifetime warranty).

11.Analysis of structural coatings.

While maintaining high transparency, a wide range of surface wear-resistant, hardness and thickness options are available. Material characteristics: light transmittance of more than 91%, surface hardness:

2h or more. At present, with the vigorous development of the capacitive screen market, the safety performance of capacitive touch glass has been paid more and more attention by the European Union, Japan and other countries and regions. Explosion-proof film for mobile phones produced in South Korea has become a new technology used on capacitive screens to prevent glass from flying apart due to external impacts.

It can meet the strict requirements of the European Union and Japan for RoHS.

In addition to the above explosion-proof applications, touch screen manufacturers at home and abroad re-apply the film cover plate to the OGS when designing a new OGS scheme, that is, the film printing cover plate is used to laminate OCA and monolithic ITO glass to form the so-called OGS, which has the lowest cost and has been widely promoted in the entire industry.

It is only anti-fragmentation, and it cannot be used in dangerous places where flammable and explosive gases appear.

It can effectively prevent the broken and scattered glass panel caused by the accidental impact of the mobile phone, reduce the hidden damage of the glass panel, ensure the safety of users, and maintain the unique luster and texture of tempered glass, and improve the surface hardness. In dangerous places where flammable and explosive gases appear, it is more reliable to use explosion-proof mobile phones, such as explosion-proof mobile phones iOutdoorF1 (explosion-proof version).
