1. What are the optical glasses?
Nowadays, electronic products have gradually become an indispensable part of daily life and have had a profound impact on people’s lives. Among these electronic products, the one we are most exposed to is the touch screen, that is, optical glass, which includes mobile phones, computers, navigation instruments, various electronic touch screens, etc. Magnesium oxide, as the main additive for optical glass, has also been widely valued and studied.
2. Advantages of magnesium oxide
The chemical raw materials often added to optical glass are magnesium oxide and calcium oxide, but calcium oxide will increase the disadvantage of glass crystallization tendency, so magnesium oxide is now used instead of calcium oxide. According to Zehui Magnesium’s research, adding magnesium oxide to glass can effectively control the hardening speed and crystallization performance of glass liquid, mainly the high-temperature physical properties of glass, while improving the melting performance of glass, playing a role in fluxing, and controlling the hardening speed to meet the needs of high-speed molding.
The optical glass-specific magnesium oxide produced by Messi Biology uses self-produced high-purity magnesium hydroxide as raw material, and obtains high-purity magnesium oxide after high-temperature calcination. The quality is stable, the product purity reaches 99%, and various heavy metal indicators reach PPM level. It has the characteristics of high purity, high specific gravity, and few calcium and iron impurities. It can be well integrated with glass components, which is conducive to improving the quality of glass.
3. The main uses of magnesium oxide in producing glass
3.1 Coating used on the surface of lenses
It has strong anti-reflection, increases the permeability of light, does not reflect light, and can effectively block ultraviolet rays.
3.2 Coating used on the surface of glass
It keeps the surface of the object in a brand new state for a long time, and will not be easily contaminated by external substances. When cleaning the surface of the object, some stains on the surface of the object can be easily cleaned.
3.3 Coating used on the surface of the car
Car coating has the function of preventing paint oxidation and aging, corrosion resistance, high temperature resistance, scratch resistance, super environmental protection, and self-non-oxidation.
3.4 Liquid crystal glass and microcrystalline glass
Liquid crystal glass and microcrystalline glass can use magnesium oxide as raw materials. Magnesium oxide single crystals for optical components are also made of high-purity magnesium oxide. It is mainly an auxiliary additive. Generally, there are great requirements for fineness and purity. It needs to reach the level of high-purity magnesium oxide before it can be used.
