The secret to choosing phone tempered glass screen protector, is 9H hardness the only criterion for testing truth?
The hardness of this super chicken 3D tempered glass phone screen protector introduced today has naturally reached the legendary 9H hardness. Why do you say that? Because other businesses say so, we naturally have to say it.
Just like the classic Wahaha advertising slogan of the chicken thief - Wahaha mineral water has been purified through 12 processes... In fact, almost all mineral water has undergone 12 levels of purification.
Today I will reveal the secret to you, and I hope to give you a correct guidance on purchasing.
The hardness unit represented by H is not the Mohs hardness unit we usually say (9 of the Mohs hardness is the strongest hardness that diamonds have!), but refers to the hardness of the pencil lead (graphite)! (Yes, it is the H in the 2B and 2H pencils)
Tempered glass phone screen protector is a specially treated glass phone screen protector, but in essence, it is still made of glass. According to Mohs hardness, the hardness of glass material is about 6, which is higher than the highest hardness of graphite. Therefore, the hardness of all qualified tempered glass phone screen protectors should be above 9H!
We can see from the Mohs hardness scale that the hardness of glass is higher than that of iron, which is at the same level as stainless steel, so general iron props will not leave scratches on the glass phone tempered glass screen protector (under the standard pressure of 500g).
It is recommended that you do not use a knife to test your own phone tempered glass screen protector. You must know that the hardness of glass phone screen protectors of different qualities and types fluctuates. Stainless steel knives may scratch the phone tempered glass screen protector with a hardness of 9H!
In addition, the hardness of quartz is higher than that of glass phone tempered glass screen protector, and it can scratch the tempered glass phone screen protector 100%. This is why the phone tempered glass screen protector that cannot be scratched by a knife will be scratched beyond recognition in daily use. . After all, quartz sand is everywhere in life. If you don’t believe me, you can experiment with sandpaper, it can scratch your tempered glass phone screen protector 100%!
To sum up, mobile phones with a phone tempered glass screen protector should be protected in normal use, otherwise the phone tempered glass screen protector will soon become a big face.
The role of the phone tempered glass screen protector is not just "anti-scratch", in my opinion, the role of the phone tempered glass screen protector lies more in the "explosion-proof screen"! After all, it costs more than 1,000 yuan to replace an original Apple screen...and the explosion-proof screen is the biggest advantage of WEADDU tempered glass phone screen protector
According to the product test data of the factory, the explosion-proof screen rate of WEADDU3D tempered glass phone screen protector is about 66.7%. I believe those who have used it know it. In the revolutionary spirit of diligence and frugality, I will not do a real machine test for the 33.3% probability here. If I win the lottery, I will eat dirt next month...
In addition to the anti-wear and explosion-proof screen, 3D is another major feature. The 3D phone screen protector can better paste the curved screen of the mobile phone, which is finally upgraded from the traditional 2D and the transitional 2.5D.
The edge of 2D phone screen protector feels abrupt, which is basically eliminated. If it is a non-curved mobile phone screen, then choose 2.5D phone screen protector; if it is a curved mobile phone screen, then you must use 3D phone screen protector!
