What Is The Best Screen Protector For Phone?

Sometimes we bought a tempered glass screen protector film,but do we know what is the best tempered glass screen protectors?Below are some tips for us to know more about it.

Hardness and Density of Tempered Glass Screen Protector: The tempered glass screen protector is made of glass. After 4 hours of tempering and cooling, the hardness of the glass is greatly improved. The tempering time is also related to the density of the tempered glass screen cover. If the density of the tempered glass is not good enough,it will very easy to break, and it will be broken into pieces, which are generally easy to hurt the skin.So how to test?

We generally test the density and hardness of tempered glass screen guard by bending test, which everyone can test. Reminder: Test with a foam bag or a bag of frosted bags to avoid injury during the test.And if the glass show us dense mesh,then the glass is good one.

Anti-scratch: This point is the most concerned by everyone. At present, the scratch-resistant materials in the industry are basically the same, and the characteristics are good. Only the scratch-proof and non-scratch-proof points, the standard method is to use a hard 9H pencil to push down 10 times at a 45-degree angle with a force of 500G. If there is no scratch, it is considered to be 9H hardness. The simple method is to use a slightly hard metal device such as blades, scissors and keys to scratch. If it is very easy to scratch, it is determined that it is not scratch-resistant. If it is not scratched, it can be confirmed to have scratch resistance.




Exhaust-ability: Whether it is bubbled when the tempered glass protective film is installed, and whether it is quickly and automatically adsorbed. It should be noted that the glue basically has an automatic exhaust function, that is to say, if you tear off the release film and put it on a clean screen, it will be installed automatically, leaving no bubble. However, the speed of its automatic attachment is inversely proportional to the setting force of the silicone. That is to say, the smaller the adhesion, the faster the exhausting speed. For example, the more we use the sticky force, the slower the exhausting speed. And the usual transparent sealing tape used by us usually has a lot of adhesion, so when you use it, it will not exhaust itself, but will find the closest surface to absorb, so there will be many bubble wrinkles.


Anti-fingerprint: anti-fingerprint is not 100% anti-fingerprint, refers to the strength of anti-fouling. But how to know it is better or not? Dripping! The dripping water is on the surface of the glass, in the shape of water drops, and the angle of the water is more arched, indicating that the anti-fingerprint effect is better,it will be like mercury falling on the ground without any trace.


Now,do you know what is the best tempered glass screen protection?
