As a new generation of nano-scale thermal insulation materials, aerogel insulation materials have become the main force of thermal insulation materials in the future. Especially since 2018, aerogel insulation materials have been trusted by more and more industries, why What is the aerogel insulation material so good?
First, the aerogel insulation material has a small thermal conductivity. The main component of the product is an aerogel. Its molecular diameter is very small, and the particle size of the particles passing through the heat is very small, so the thermal conductivity is very low compared with the general insulation material. At the same time, the pore volume between the molecules is small, the heat transfer effect is smaller than that of the general insulation material, but slightly larger than the nanoplate, and the sunscreen is added to the aerogel insulation material, which can block the infrared penetration well. Reduced heat radiation.
Secondly, the aerogel insulation material has a very good fireproof performance. The aerogel insulation material has an anti-flame and smoke diffusion coefficient of less than 10, which is a Class A fireproof material. Another very good advantage is waterproof. Conventional insulation materials such as aluminum silicate insulation cotton products can not see water. The heat insulation effect of the product will be worse after encountering water, but the aerogel insulation material can achieve waterproof effect. Especially for some pipe insulation, aerogel insulation is the best choice.
Aerogel insulation has very good corrosion resistance and does not corrode carbon steel and stainless steel. It is safe and reliable for thermal insulation. The product can also withstand very high pressures, with no change in performance except for variations in thickness. The construction is also simple, and the service life can be more than 20 years, and the heat resistance and heat insulation effect will not change. It can be said that it is a kind of thermal insulation material with great potential in the future. But the only downside is that the price is relatively high.
