Application of magnesium oxide in thermal conductive materials
With the rapid development of science and technology and the continuous advancement of electronic technology, electronic equipment is developing in the direction of miniaturization and high performance. However, the miniaturization of equipment also brings heat dissipation problems. Especially in the context of the gradual increase in equipment power, the problem of heat being unable to be effectively dissipated becomes more and more prominent. In order to solve this problem, a material with high thermal conductivity and electrical insulation properties is urgently needed to meet the application requirements.
At present, polymer composite materials have been widely used in the field of electronic and electrical appliances due to their advantages such as easy processing and good molding effects. However, such materials usually have poor thermal conductivity, so high thermal conductivity fillers need to be added to the polymer to improve its thermal conductivity. Among many inorganic fillers, magnesium oxide (MgO) has become a thermally conductive filler with great potential due to its excellent thermal conductivity, electrical insulation properties, abundant magnesium resources in my country, and low cost.
Studies have shown that when polymer materials such as PVC are filled with magnesium oxide, their thermal conductivity is significantly improved. Especially when spherical magnesium oxide is used as a filler, the thermal conductivity of PVC material is even better, and its thermal conductivity can even be doubled. This shows that magnesium oxide, as a filler in thermally conductive materials, not only effectively enhances the thermal conductivity of polymer composites, but also maintains good processability and insulation properties.
In addition, by adjusting the shape and size of magnesium oxide, its thermal conductivity can be further optimized to adapt to application needs in different scenarios. This flexibility provides more possibilities for the wide application of magnesium oxide in the field of thermally conductive materials, and also promotes its in-depth development in polymer composite materials.
All in all, magnesium oxide is a thermally conductive filler with excellent performance, which plays an important role in improving the thermal conductivity of polymer composites. It can not only significantly improve the performance and heat dissipation efficiency of electronic products, but is also crucial to ensuring the safe operation of electronic equipment. At the same time, this also provides an important opportunity for the high-value utilization of my country's magnesium resources and injects new impetus into the development of electronic equipment and thermal conductive materials.
