1、 Research and development field of glass materials

This device is for the development and performance optimization of a new glass formula The 'core detection tool' uses conductivity data to infer the microstructure and composition compatibility of glass melts. Specific application scenarios include:

The research and development of special glass is aimed at special categories such as photovoltaic glass, electronic glass (such as display panel substrate glass), optical glass, and high-temperature resistant glass. Conductivity is one of the key performance indicators. For example:

In the production of photovoltaic glass, it is necessary to determine the alkali metal ions (such asNa⁺TheK⁺）Migration rate ——Rapid ion migration can lead to a decrease in electrical resistivity after glass forming, affecting the insulation of photovoltaic modules. Therefore, it is necessary to adjust the formula (such as introducing)Ca²⁺TheMg²⁺Inhibiting the migration of alkali ions and verifying the optimization effect through conductivity testing;

In the development of electronic glass (such as ultra-thin glass), the conductivity of molten glass directly affects its performance at high temperatures The clarification process (bubble discharge efficiency) may result in abnormal viscosity of the melt due to high conductivity, and the optimal composition ratio needs to be determined through testing.

This device is commonly used by research institutions in basic glass structure research to explore the properties of glass melt at high temperatures “structure-Conductive relationship”. For example, by changing the glassSiO₂TheB₂O₃Measure the changes in conductivity at different temperatures based on the content of the network forming body, and analyze the influence of the density of the network structure on the ion conductive channels; Or study rare earth elements (such asLa³⁺）The regulation mechanism of doping on the conductivity of molten glass provides theoretical support for the development of functional glass, such as conductive glass.
