Aerogel is a kind of colloid, also called dry gel, density is relatively small.
An aerogel is a colloid, also called a dry gel, with a relatively low density. When most of the solvent is removed from the gel so that the liquid content of the gel is much less than the solid content, or when the spatial network structure of the gel is filled with gases and has the appearance of a solid, this is a dry gel, also called an aerogel. Such as gelatin, gum arabic, silica gel, hair, nails and so on. Aerogel also has the properties of gel, that is, it has swelling, thixotropy and desiccation, so aerogel insulation sheet: what is aerogel used for?
What are the characteristics of aerogel?
1, nano aerogel is characterised by low density and good heat insulation, so it can be widely used as heat insulation material in military and aerospace fields, thermal batteries, industrial and architectural insulation, solar water heaters and other fields.
2、Aerogels have the advantages of small particle size and large surface area. Nano aerogel can also be used as catalyst and catalytic carrier, gas or liquid adsorbent.
3, nano aerogel has high calorific value, waterproof after combustion, will not cause pollution to the environment, so aerogel can be used as hydrogen storage materials.
4, Aerogel has low dielectric constant and high specific surface area, so it can be widely used in various fields of electrochemistry.
5、Nano aerogel has excellent heat insulation properties, so it is widely used in daily life. It can be used in the production of cold-proof appliances, cosmetics, toothpaste, ink, sporting goods and so on.
6, Not only that, nano aerogel is also widely used in other fields, such as advanced technology detectors.
