Tempered glass / Reinforced glass belongs to safety glass. The glass has a fairly good wear resistance and is very hard with a Vickers hardness of 622 to 701. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, it firstly counteracts the surface stress so as to increase the carrying capacity and enhance the self- Wind pressure, cold summer, impact and so on. The tempered glass protective film is a high level of security for mobile phone screen protection.
Tempered glass protective film is the most widely used in the world, Europe, therefore, is the main supplier of tempered glass protective film is the European market, tempered glass protective film in China will also be rapidly popularized, and will form a huge industrial chain market . Although toughened glass protective film is a new type of mobile phone protective film, there are quite a few manufacturers of tempered glass protective film. According to incomplete statistics, there are about 100 domestic ones, mainly in Guangdong, but also growing with each passing day.
As early as 2012, the relevant researchers in the United States put "tempered glass" glass used in the field of mobile phones, designed to protect the screen and tempered glass protective film, is the screen saver new high-end products. In 2013, some competent domestic manufacturers introduced the relevant high-tech raw materials and technologies from abroad, developed their own brand of toughened glass cell phone protective film, and provided professional protection for domestic users!
Toughened film is to prevent the screen from falling when the phone slides. Not for scratch. Ordinary film is the hardness of 3H, the use of end months will not have too much scratches, the reason why choose toughened screen because: high hardness, low toughness, the phone fell, you can very good anti-broken screen. When the phone off the ground, to withstand the impact of a large tension over the screen broken. Temper film toughness when the phone out of tension when the film will withstand tension This greatly reduces the main screen to withstand the tension.
Pros and cons of products：
How to identify a good tempered glass protective film:
1. Exhaust is not good phone surface residual air bubble phenomenon;
2. tempered glass around the corner can not paste, bubble phenomenon;
3. toughened glass and cell phone can not stick, easy to fall off phenomenon;
4. Tempered glass is too thick, the impact of light transmittance, and thicker cell phone thickness;
5. Tempered glass paste too thick, affecting the phone display transmittance;
6. Tempered glass paste in the phone, the phone surface watermark phenomenon.
7. Tempered glass film is also divided into straight edges and arc edges, the arc edge is more rounded than the bevel, not easy to hurt
