The chemical tempering treatment of Touchscreen Panel Glass is based on ion exchange technology. Under specific temperature conditions, the Touchscreen Panel Glass is immersed in high-temperature molten salt, so that the small volume alkali metal ions on the surface of the glass are exchanged with the large volume alkali metal ions in the molten salt. This ion exchange forms a compressive stress layer on the surface of the Touchscreen Panel Glass and a tensile stress layer inside, thereby significantly improving its strength. The bending strength of the Touchscreen Panel Glass that has been chemically tempered is usually 3 to 5 times that of ordinary glass, and the impact strength is 5 to 10 times that of ordinary glass. This significant improvement in strength makes the Touchscreen Panel Glass more tough and durable when subjected to external impact.
The bearing capacity of the Touchscreen Panel Glass after chemical tempering is significantly enhanced, and it can maintain the integrity of the structure when subjected to pressure or impact, thereby ensuring the normal use of the touch screen panel. Even if the Touchscreen Panel Glass breaks after a great impact, its fragments are in the form of small particles with blunt angles, greatly reducing the risk of injury to the human body. This feature gives the Touchscreen Panel Glass a significant advantage in safety.
Chemical tempering treatment significantly improves the rapid cooling and heating resistance of Touchscreen Panel Glass, and it can usually withstand temperature changes of more than 150°C without breaking. This feature enables Touchscreen Panel Glass to have better application performance in environments with large temperature changes. Due to the improvement of thermal stability, Touchscreen Panel Glass can maintain stable performance in a variety of application scenarios such as outdoor electronic equipment and automotive displays.
Touchscreen Panel Glass after chemical tempering is not easy to deform during processing and can maintain the stability of product shape. This feature enables Touchscreen Panel Glass to have higher precision and reliability during the manufacturing process. Chemical tempering treatment is not only suitable for flat-shaped Touchscreen Panel Glass, but also can be used for processing various shapes such as arc and cylindrical. This makes the design and application of Touchscreen Panel Glass more flexible and diverse.
Chemical tempering treatment can also improve the surface hardness of Touchscreen Panel Glass, making it more wear-resistant and scratch-resistant. This is of great significance for the long-term use and maintenance of Touchscreen Panel Glass. Chemical tempering treatment also has a positive effect on the optical properties of Touchscreen Panel Glass. It can reduce the reflection and glare problems of glass, improve the clarity and visibility of the screen, and bring better visual experience to users.
