Characteristics and wide application of aerogel felt, a new thermal insulation material

Aerogel blanket, as a new type of porous solid material, has received extensive attention for its unique physical and chemical properties. It is usually made of aerogel particles through a special process, with high porosity, low density and excellent thermal insulation properties. In addition, aerogel felts also have good sound absorption, shock resistance and corrosion resistance, making them have great application potential in many fields.
The preparation process of aerogel blanket usually includes the steps of sol-gel reaction, supercritical drying and compression molding. Through these steps, an aerogel blanket having excellent properties can be obtained. Its unique pore structure makes it have excellent thermal insulation performance, which can effectively reduce heat conduction and radiation heat transfer. At the same time, the sound absorption performance of the aerogel felt is also very good, which can effectively reduce noise pollution.
Characteristics of aerogel blanket
Low thermal conductivity: The thermal conductivity of aerogel blanket is between 0.02 and 0.1W/(m · k), making it an effective thermal insulation material.
Has a certain tensile and compressive strength: this makes the aerogel felt in practical applications to withstand a certain physical load, to maintain the stability of its structure and performance.
Good flexibility: Due to its special manufacturing process, aerogel felt has good flexibility and ease of cutting, which is easy to install and use on various complex surfaces.
Low density: The density of the aerogel blanket is low, which means that it can provide better insulation when in use, while maintaining a low weight.
Inorganic fire prevention: aerogel felt has the characteristics of inorganic fire prevention, which is suitable for occasions requiring fire prevention and heat insulation.
Overall Hydrophobic: The hydrophobic nature of the aerogel blanket allows it to maintain good performance even in wet environments.
Green environmental protection: The production and use of aerogel felt has little impact on the environment and meets the requirements of green environmental protection.
