Nano aerogel blanket is a new material with high pore rate, low density, and excellent insulation performance. Processes.its pore rate is very high, it can absorb a large amount of liquid and gas, and has excellent thermal insulation, fire resistance and acoustic performance. The main component of nano aerogel blanket is silicon or other oxides. The preparation methods include supercritical drying, solitary-gel method. These preparation methods can control the pore size and pores of the gas gel, thereby regulating their performance, such as adsorption, insulation, insulation, damping, filtering, etc.
