Supercritical CO2 Drying Technology
Release time:
2019/06/03
Supercritical drying technology is the first technology to realize the batch preparation of aerogel technology, which is relatively mature, and is also the technology adopted by aerogel enterprises at home and abroad. Supercritical drying aims to reach the critical point of the solvent during the drying process through pressure and temperature control, forming a supercritical fluid. Solvents in the supercritical state have no significant surface tension and are avoided during drying of the material. Shrinkage and fragmentation in the material, thereby maintaining the original structure and state of the material, preventing aggregation and coagulation of primary nanoparticles, and preparing high-surface materials, such as nanomaterials and aerogel materials.
