The company produces steel 2.5D curved membrane is 0.3mm thin with water chestnut contours, the film looks back edge technology allows thinner, more powerful explosion. Product Features: 1. Japan imported material, glass material 2. Asahi Glass scratch glass surface after treatment, riot processing, index reached 8H. 3. The anti-glare glass surface after treatment, non-reflective, clear and vivid images, protecting quality color without distortion. 4. a long time not because of deterioration, not like other left-corrosive agent pasted on the screen surface, safe, reliable, repeatable paste, without leaving any traces. Features: a strong scratch, abrasion 9H (best other quality films, which wear-resistant grade only 3H, does not take too long, you have to replace this film that the use of a utility knife or weapon is not above scraping. produce traces of long use time.) Second, the explosion-proof screen, drop, anti-bacterial, anti-glare, radiation III high sensitivity touch screen up to 98% light transmission electron waves can be prevented harm to the human body. Fourth, the picture is clear, highlighting the three-dimensional, improve the visual effect five, prolonged use of eye fatigue, and better protect their eyesight. Does not affect the use of other mobile phone accessories. Sixth, do not deteriorate due to long time, not like other corrosive adhesive paste left on the screen surface, safe and reliable. Repeatable paste, without leaving any traces, non-corrosive surface. Non-professionals can easily free fit. Seven, explosion-proof membrane: even if the glass is broken and will not crushed into small sharp pieces. Will not cause any harm to the human body and cell phone. Steel membrane is to prevent the phone off, and broke the screen. Not to scratch. Ordinary film is 3H hardness, finished a few months there will not be much use to scratch, steel screen was chosen because: low hardness and high toughness, the phone fell, can be good shatterproof screen. When the phone is off the ground, to withstand the impact of large, tension is too large screen on the break. Steel film toughness low tension film came when the phone will be greatly reduced under tension so that the main screen to withstand tension. How to identify a good glass protection film: 1. Exhaust bad phone surface residual bubble phenomenon; 2. Tempered glass paste live around the corner, the bubble phenomenon; 3. glass adhesion and cell phone could not easily fall off phenomenon; 4 Tempered glass is too thick, the impact of light transmittance, and the thickness of the thickened cell phone; 5. glass paste glue is too thick, the phone displays the influence of light transmittance; 6. glass paste after the phone, the phone surface watermark phenomenon. 7. glass film also points straight edge and arc edge, arc edge relative to the hypotenuse more mellow, easy to hurt the hand advantage: the surface hard enough to scratch, even if you take a knife in the above plan will not get to spend hard as iron The hardness is below the glass, let alone through the toughened. Disadvantages: brittle. So hard to make something so thin that it is quite easy to be broken. If the paste on the phone, the screen being vigorously impact, glass-like film itself split. You have changed. But most people are on the screen saver is very good, is not it? Ex scratch: to prevent the phone accidentally bump caused by flying broken glass panels, glass panels to reduce the harm implicit guarantee user safety. Meanwhile prevent accidental scratches, impact of mobile phones appearance. Simple and easy to use, can not afford bubbles. Screen transmittance up to 98%. To prevent harm to the human body electron wave. Does not affect the mobile phone sets and other mobile phone parts. Cons: Compared with other film was relatively thick, but also affect the sensitivity of the touch screen, but also because of the hard brittle glass features, overall performance is very fragile. 1; glass and steel post can no longer be cut and processed, only in front of the glass on steel processed to the desired shape, and then steel processing. 2; glass, although the intensity stronger than ordinary glass, tempered glass, but there is the possibility of self-destruct (self-breakage), and the possibility that blew ordinary glass does not exist. 3; tempered glass there will be uneven surface phenomena (wind spots), there is a slight thickness thinner. The reason is because the thin glass in the hot melt to soften, after rapid cooling to make a strong wind, so that the internal gap between the crystal glass becomes small, the pressure becomes large, the glass in the steel before the steel than thinner.
