Mobile phone film new flexible toughened glass membrane, really is the glass?
Tempered glass (Temperedglass/Reinforcedglass) belongs to safety glass. Glass has a fairly good abrasion resistance and is very hard, with a Vivtorinox hardness of 622 to 701.
Glass membrane materials: ab. Because the plastic protective film glass film unlike can electrostatic adsorption on the mobile phone screen, with a thin layer of flexible double-sided adhesive tape in the glass film layer, this thin layer of flexible double-sided adhesive is called ab.
Toughened glass is a kind of prestressed glass, in order to improve the strength of the glass, the methods commonly used in chemistry or physics, formed on the surface of glass glass under compressive stress, first offset surface stress force, so as to improve the bearing capacity of reinforced glass, its wind, cold, impact etc.. The toughened glass protective film is the highest security level for mobile phone screen protection.
The toughened film is designed to prevent the phone from slipping and crashing the screen. Not to prevent scratching. Ordinary film is the hardness of 3H, the use of a few months, there will not be too much scraping, the reason why the election of the steel screen is: high hardness, low toughness, mobile phones fell, can be very good anti broken screen. When the mobile phone drops on the ground, the impact is great, the tension is too large and the screen is broken. Toughened film toughness is low, when the handset sends out the tension, the membrane can bear the tension, thus greatly reduced the main screen to bear the tension.
