Aerogel as a new solid material for nanoporous structural materials is characterized by ultra light, heat insulation, transparency, heat preservation and fire prevention. Aerogels have a huge market in the field of energy conservation. They are important parts of the future thermal insulation field. However, due to the fact that the technology field has not yet been completely broken, the application in the application fields such as energy-saving doors and windows, pipeline insulation, wall insulation, thermal insulation coatings, concrete additives and so on is still in the initial attempt, but its development potential will pry the 100 billion market.
Let's take stock of aerogel applications at home and abroad.
1, aerogel particles are mainly hydrophobic and hydrophilic, which are less than 1 micron particles. This method is relatively simple and has the possibility of industrialization. The thermal conductivity is about 0.009-0.012, and the density is about 30-100KG/ cubic. The specific surface area can reach 600 m2 / g.
2, aerogel felt
The combination of aerogels and fiber reinforced composites successfully solved a series of problems, such as low mechanical strength, easy crushing and poor heat insulation.
3, aerogel glass
4. Application of aerogels in building pipelines
Aerogels, such as thermal insulation and hydrophobicity, are ideal insulation materials for pipes. In addition, aerogels are inorganic thermal insulation materials. The average energy consumption per kilometre of high temperature steam pipes in the use of 8A can be saved by tens of millions of yuan.
5, the use of aerogels in wallboards and roofs.
The thermal conductivity of aerogels is 1/3 of the polystyrene board, far lower than other building insulation materials. At the same time, aerogels are inorganic insulation materials of A1 grade, and the density of aerogels is lower than 100KG/m3, which is convenient for construction and reduces the weight of the whole building.
6, application of aerogels in coatings
Compared with its heat preservation effect, air temperature has the function of supplementary heat preservation. It can not only be used for the heat preservation of external walls, but also for the heat preservation of the bottom of buildings. At the same time, inorganic silicon industry is a good waterproof and anticorrosive material.
