[0002] Silica aerogel powder, as a novel material with unique properties, has shown broad application prospects in many fields. In the aerospace field, due to its low density and high thermal insulation properties, it is used to manufacture thermal insulation components for aircraft, effectively reducing the weight of the aircraft while improving the thermal insulation effect, ensuring the safe operation of the aircraft in extreme environments. In the construction industry, as a high-performance thermal insulation material, it can significantly reduce building energy consumption, improve energy utilization efficiency, and help achieve green building goals. In the field of electronic equipment, it can be used to make heat dissipation materials for electronic components, quickly dissipating heat, preventing overheating damage to components, and extending the service life of electronic equipment. Regarding screening accuracy, some screening devices cannot accurately separate raw material particles of different sizes, making it difficult to meet the strict standards for raw material particle size distribution in silica aerogel powder production.
