The tempered glass film is made in this way.
China Glass Network [1] Tempered glass membrane is <br> <br> glass film is more popular advanced phones protective mask, cell phone glass film played an important role in the protection of our mobile phones, but many People don't know much about it yet. Self Adhesive Rubber Pad and Mat Self Adhesive Rubber Feet, also known as self adhesive Rubber Feet&Foot and Self Adhesive Rubber Mat, which is made of rubber material with backing adhesive tape (glue layer) and produced by compression molding and die-cutting tool. Self Adhesive Rubber Foot are widely applied in Electronics, Medical, Vehicle, Electronic, Automotives, etc. Self Adhesive Rubber Pad,Self Adhesive Rubber Mat,Custom Self Adhesive Rubber Mat,Rubber Pad Feet Xiamen The Answers Trade Co.,Ltd. , https://www.xmanswer.com
The tempered glass film is characterized by the use of tempered glass material, which can achieve better scratch resistance than ordinary plastics, and has better anti-fingerprint and anti-oil effects. And you can think of the tempered film as the second external screen of the mobile phone. If the mobile phone falls, the tempered film can absorb a certain amount of damage, which can reduce the probability of broken screen.
The tempered glass film has the following main features:
1, high-definition: light transmittance of more than 90%, the picture is clear, highlighting the three-dimensional sense, improve the visual effect, long-term use of the eyes is not easy to fatigue.
2, anti-scratch: glass material after high-temperature tempering treatment, much higher than ordinary film, common tools, keys, etc. in daily life will not scratch the glass film, but the plastic film is different, it will appear scratches after a few days of use The things that can scratch them are everywhere, such as keys, knives, zippers, buttons, nibs, and so on.
3. Buffering: For mobile phones, the tempered glass film can play a buffering and damping effect. If the falling is not serious, the tempered glass film will be broken, and the screen of the mobile phone will not be broken.
4, ultra-thin design: the thickness is between 0.15-0.4mm, the thinner the sticker on the mobile phone does not affect the appearance, the ultra-thin glass is attached, it is like a perfect fit with your mobile phone, combined into one.
5, anti-fingerprint: the surface of the glass film is treated with added coating, the touch is smoother, so that the hateful fingerprint is no longer easy to remain, and most of the plastic film is touch-sensitive. 6. Automatic fit: align the tempered film with the mobile phone , put it on automatically, do not need any skills, automatic adsorption.
Based on the above characteristics, the choice of glass tempered film to protect mobile phones is better than plastic film. So how is the tempered film produced? What kind of raw materials does it use? What process does it use?
How is the tempered glass film made?
Compared with other industries, the film technology is not high, and most people think that tempered glass film will have such a view. Recently, we interviewed a film manufacturer. During the interview, we found that the production process of tempered glass film is not as simple as we think. The tempered film has to go through a series of complicated procedures, and later it can become a piece that you can see. Smooth, translucent film.
Raw materials: glass different materials differ <br> <br> glass membrane is made of different brands of glass from raw materials. Since it is a tempered glass film, the importance of its raw material, glass, is self-evident. The original glass is divided into two parts according to the manufacturer. It can be divided into domestic and imported parts. Domestically produced include Luobo and CSG. Asahi Glass (AGC), plate glass, central glass, Schott, Germany and Corning, USA. The cheap tempered glass film is mainly made of domestic glass original film.
<br> <br> glass raw materials from the quality, the high-end imports (Corning, Schott, Asahi Glass)> Mid-made (such as Glass)> low-end domestic (brand-name). AGC, SCHOTT, and Corning each have their own representative products. The quality of these three products is in the middle, and the difference is not great. So what are the main differences between domestic and imported? The main difference between the two is the light transmittance and price. The light transmittance of domestic materials can only reach 92% or even lower. The imported materials ensure that the light transmittance reaches over 95%, which has a better visual experience. The import price is of course higher.
The thickness of the glass film is of course the smaller the hand feel, the higher the fit, and the thicker the hand feel. Now if you need to buy a glass film, it is better to buy 0.2mm, which is relatively cost-effective. Nowadays, there is a domestically produced glass with a relatively large thickness. The thickness is less than 0.5mm, which is difficult to feel by hand. Whether it is 0.2mm and 0.3mm, or 0.3mm and 0.4mm, it is very difficult to distinguish. . Therefore, there are some bad tempered protective film manufacturers on the market to confuse consumers.
The glass film with a thickness of 0.4mm or more is too thick and affects the hand feeling. Now it has basically been eliminated.
0.3mm is the current mainstream entry thickness, but it looks a little thicker, the price is about 50 yuan.
0.2mm is the current mainstream high-quality tempered film. Its permeability and feel are excellent. The price is slightly expensive, and it is basically around 60 yuan.
0.15mm is the current thinner process, the pursuit of good transparency and feel is not bad money for the local tyrants, split directly to change one, the price is more than 100 yuan.
Here, the 0.2mm tempered glass film raw material is said. So far, the original thickness of the raw material is 0.2mm, and only Corning and Schott are two kinds of glass. There is also a 0.2mm tempered glass film raw material which is immersed in chemical water to reduce thickness with a glass raw material of 0.33 mm thickness. This thinned glass material will not be as uniform in thickness. The thick place may be 0.25mm and the thin place is 0.22mm. The treated 0.2mm glass will be worse than the original 0.2mm in terms of toughness and flatness. However, the cost is still much higher than the ordinary 0.33mm glass.
Corning of the United States and Schott of Germany are able to achieve a thickness of 0.2 mm or less on the market, and the cost is high. However, there are many commercially available tempered glass films of 0.2 mm and 0.15 mm. Why is that? In fact, the thickness of the virtual standard is an open secret in the tempered glass film industry, 0.3mm is said to be 0.2mm or even 0.15mm. The difference in thickness is less than 0.1, which is difficult to feel by hand. Therefore, the virtual mark thickness is "open secret."
