Description

Technical Field

[0002] Aerogel has extremely low thermal conductivity, much lower than traditional insulation materials, and is one of the most efficient insulation materials currently available. In the field of new energy, such as solar thermal power generation, fuel cells, lithium-ion batteries, nuclear reactors and other equipment, efficient thermal management is essential. Aerogel can effectively isolate the heat transfer between high-temperature components and the external environment or internal low-temperature components, improve energy conversion efficiency, reduce energy loss, and extend equipment life.

[0003] Aerogels need to be crushed during the preparation process, and the crushing equipment for aerogel raw materials refers to mechanical equipment specially designed to crush aerogel precursors or prepared aerogel materials and reduce the particle size to the required specifications.

By precisely controlling the particle size after crushing, key parameters such as the bulk density, porosity, and specific surface area of ​​the aerogel in the final product can be adjusted to optimize its thermal insulation, adsorption, sound insulation, catalysis and other properties. For example, finer aerogel powder can provide a larger specific surface area, which is beneficial to improve adsorption capacity or enhance interfacial contact with other materials, thereby improving the overall performance of the composite material.
