The anti-scratch and wear-resistant performance of hd fully transparent tempered film customization is achieved through the synergy of raw material selection, special processing technology and surface treatment technology. These technical means jointly build a solid protective barrier for the mobile phone screen.
In the selection of raw materials, high-quality glass sheets are the basis for achieving anti-scratch and wear-resistant performance. Customized hd fully transparent tempered film customization usually uses high-purity silicate glass. This kind of glass material has a uniform and dense internal structure and very little impurities, which fundamentally guarantees the strength and stability of the glass. Compared with ordinary glass, high-purity silicate glass itself has better scratch resistance. The chemical bonds between its internal atoms are tightly combined, which can effectively resist scratches from external objects and reduce the possibility of scratches, laying a good material foundation for the subsequent improvement of anti-scratch and wear resistance.
Tempering process is a key link in enhancing the hardness of glass. After the selected glass sheet is cut into a suitable size, it will be sent to a high-temperature tempering furnace for heating treatment. When the glass is heated to a temperature close to the softening point, it is quickly cooled down by air cooling or liquid cooling, so that the surface of the glass is quickly cooled and shrunk, while the interior is still in a relatively high temperature and softened state. As the cooling continues, a strong compressive stress is formed on the surface of the glass, and a tensile stress is generated inside. This stress distribution state gives the glass higher strength. After tempering, the surface hardness of the glass is greatly improved, and it can withstand greater external forces without easily breaking or scratching, so that the tempered film has basic scratch resistance and wear resistance.
The chemical strengthening process further improves the scratch resistance and wear resistance of the tempered film. On the basis of the tempering treatment, the tempered film is immersed in a chemical solution containing metal ions such as potassium ions, and the sodium ions on the surface of the glass are replaced with potassium ions in the solution by the principle of ion exchange. Since the radius of potassium ions is larger than that of sodium ions, a "squeezing layer" will be formed on the surface of the glass after the replacement, further enhancing the surface compressive stress, thereby significantly improving the hardness and impact resistance of the glass. This chemical strengthening treatment allows the tempered film to not only resist scratches from sharp objects, but also withstand a certain degree of impact. Even when common hard objects such as keys and coins rub against the surface of the film, it is not easy to leave obvious marks.
Surface coating technology adds extra protection to the scratch and wear resistance of the tempered film. A special wear-resistant coating is coated on the surface of the tempered film. This coating is usually composed of materials such as metal oxides or carbides with higher hardness. The wear-resistant coating is like a layer of solid armor, tightly attached to the surface of the tempered film, further improving its scratch resistance. At the same time, the wear-resistant coating can also reduce the friction coefficient of the film surface, making objects slide more smoothly on the surface of the film, reducing scratches caused by friction, and effectively extending the service life of the tempered film.
In addition to the above processes, fine processing and quality control also play an important role in scratch resistance. In the process of cutting and grinding the tempered film, high-precision equipment and processes are used to ensure that the edge of the film is smooth and flat without burrs and defects. Because the edge is relatively fragile, if there are defects, it is easy to be damaged by external impact during use, which will affect the overall anti-scratch and wear-resistant performance. Strict quality inspection links will inspect each tempered film, and screen out qualified products by simulating scratch tests and wear tests in actual use scenarios, so as to ensure that the tempered films entering the market have good anti-scratch and wear-resistant capabilities.
During use, reasonable installation methods also help maintain the anti-scratch and wear-resistant performance of the tempered film. During installation, make sure that the surface of the mobile phone screen is clean and dust-free to avoid dust particles sandwiched between the screen and the tempered film, causing scratches on the surface of the film during use. At the same time, during the installation process, ensure that the tempered film fits perfectly with the screen to avoid bubbles or warping, otherwise these parts are easily affected by external forces, resulting in damage to the tempered film and reducing its protective effect.
The anti-scratch and wear-resistant performance of hd fully transparent tempered film customization is the result of the joint action of many aspects from raw materials to processing technology to use links. Through the selection of high-quality raw materials, advanced tempering and chemical strengthening processes, surface coating technology, as well as fine processing and reasonable use, reliable protection is provided for mobile phone screens, so that users do not need to worry about the screen being easily scratched and worn during daily use.
