Silica Aerogel Blanket Description
1.Ultra-Low Thermal Conductivity: Silica aerogels typically have thermal conductivity lower than 0.03 W/m·K, which is much lower than traditional insulations like fiberglass or mineral wool. This makes them highly effective at preventing heat transfer.
2.Lightweight: Aerogels have an extremely low density (typically 0.1-0.3 g/cm³), which makes them one of the lightest solid materials known. This light weight is crucial in applications where minimizing weight is a key factor.
3.High-Temperature Resistance: Silica aerogels are known for their high thermal resistance. They can typically withstand temperatures above 1000°C, and some high-performance aerogels can endure temperatures above 1500°C.
4.Flexibility and Processability: Silica aerogels can be made into flexible mats, sheets, or other forms, making them adaptable to different application needs. They are also easy to combine with other materials.
5.Fire-Resistant: Aerogels are inherently fire-resistant, helping to prevent the spread of flames and protect underlying materials.
Typical Applications
● Oil and Gas: Used in the insulation of pipelines, drilling rigs, and other offshore or industrial facilities, silica aerogel thermal blankets reduce heat loss and improve energy efficiency.
● Industrial Equipment: Aerogels are used in high-temperature industrial settings (e.g., furnaces, boilers) to minimize heat loss and improve the efficiency of energy consumption.
● Cold Chain Transport: In temperature-sensitive logistics, aerogel blankets help maintain stable temperatures in cargo, reducing the energy cost of refrigeration.
● Firefighting: Aerogels' fire-resistant properties make them suitable for use in firefighting equipment, such as heat-resistant suits for firefighters.
Working Principle
● Porous Structure: Aerogels have a vast network of micro-pores that trap air, which significantly reduces heat transfer. Since air is a poor conductor of heat, the aerogel's structure makes it highly effective at preventing heat conduction.
● Low Density: Aerogels are extremely low in density, which contributes to their low thermal conductivity and high insulating efficiency.
● Surface Effects: The large surface area of aerogels allows for significant heat exchange between the surface and surrounding air, further enhancing the material's insulation properties.
