The role of fluorine in glass
The role of fluorine in glass is mainly reflected in the following aspects:
1. Improve transparency
Fluorine can significantly increase the transparency of glass, and improve the spectral properties of glass, making it closer to the ideal optical transparency.
2. Enhancement of hardness
Under the action of fluorine, the hardness of the glass is improved, it is more resistant to scratching and abrasion than the glass without added fluorine, and is less likely to be scratched.
3. Improvement of durability
Fluorine improves the heat resistance and chemical stability of glass, making it more durable and less likely to be affected by the external environment.
4. Improve melting performance
Fluorine is a good flux, can promote the melting of glass, and reduce the melting point and viscosity of the production of glass, is conducive to the production of high-quality, uniform glass.
Influence of fluorine on glass properties
In addition to the above role, fluorine also has an impact on various properties of glass, including:
1. Improvement of UV resistance
Fluorine can enhance the anti-ultraviolet performance of glass, effectively preventing the glass from being damaged by ultraviolet radiation.
2. Improvement of fatigue resistance
Adding the right amount of fluorine improves the fatigue resistance of glass, making it more durable and able to withstand greater cooling and temperature changes.
3. Improvement of acid and alkali resistance
Fluorine can improve the acid and alkali resistance of glass, making it more resistant to corrosion and less susceptible to external chemical attack.
4. Influence the coefficient of thermal expansion
Changes in the amount of fluorine added will lead to changes in the coefficient of thermal expansion of the glass, thus affecting the thermal stability and range of use of the glass.
Conclusion
To sum up, fluorine plays a very important role in glass, which can improve the physical and chemical properties of glass, increase its transparency, hardness, durability and corrosion resistance. However, it is also necessary to be careful not to add too much fluorine, otherwise it will affect the glass properties such as melting properties and coefficient of thermal expansion.
