What are the Advantages of Aerogel Felt as an Insulation Material?

wallpapers Industry 2020-08-26

As a new generation of nano-level thermal insulation materials, aerogel felt has become the main force of thermal insulation materials in the future. Especially since 2018, aerogel felt has been trusted by more and more industries. Why aerogel Is the felt so good?

First of all, the thermal conductivity of aerogel felt is small. The main component of the product is aerogel. Its molecular diameter is minimal, and the cross-sectional area of ​​the particles that can pass heat is minimum. Therefore, compared with general insulation materials, the thermal conductivity is very low. At the same time, the pore volume between the molecules is positively small, and the heat transfer effect is smaller than that of general thermal insulation materials but slightly larger than the nanoplate. At the same time, sunscreen is added to the aerogel felt, which can well block infrared penetration and reduce Heat radiation.

The second is that the aerogel felt has excellent fire resistance. The aerogel felt material had passed the American ASTM E84 certification, and the anti-flame and smoke spread coefficients are less than 10, and it is a Class A fireproof material. Another excellent advantage is waterproof. Conventional insulation materials such as aluminium silicate insulation cotton products cannot see the water. After encountering water, the insulation effect of the product will become worse. Still, the aerogel felt can achieve the waterproof effect, especially For some pipe insulation, aerogel felt is the best choice.

Aerogel felt has excellent corrosion resistance, and will not corrode carbon steel and stainless steel, and it is safe and reliable for heat preservation. The product can also withstand very high pressures, except for changes in thickness, without any impact on performance. The construction is too simple, and the service life can reach more than 20 years, and the heat resistance and insulation effect will not change. It can be said to be a kind of thermal insulation material with great potential in the future. But the only disadvantage is that the price is relatively high.
