Nowadays, there is basically one mobile phone. Some people with busy business even have two or three mobile phones. But have you ever noticed the difference between mobile phone glass and ordinary glass. A chemical raw material called magnesium oxide is needed in mobile phone glass, so what is the role of magnesium oxide in mobile phone substrate glass?
The high-purity magnesium oxide produced by Hebei Meishen Technology Co., Ltd. is particularly suitable for the production of photoelectric glass and various mobile phone display glasses. Magnesium oxide for mobile phone substrate glass has the characteristics of high purity, large specificity, less calcium and iron impurities, and low chloride content. It can be well integrated with the glass composition. The high content of magnesium oxide and less impurities are beneficial to improve the quality of the glass, and the content of chloride Very low can avoid the generation of corrosive hydrogen chloride gas during heating and melting, which is beneficial to protect precision equipment from corrosion and damage.
The indicators of magnesium oxide for mobile phone substrate glass are as follows: magnesium oxide ≥99%, iron oxide ≤0.005%, sulfur element ≤0.03%, chloride ≤0.05% calcium element ≤0.02%, acid insoluble matter ≤0.05%, and the content of heavy metals must comply with EU ROSH instruction.
