Nanometer porous aerogel (abr. as aerogel) is a kind of solid gel material with gas dispersion medium, in which the net structure is formed by mutual accumulation of gel particle or high polymer molecule. It belongs to mesoscopic substance and can be used as catalyzer carrier, electrode, absorbent, heat and sound insulting materials and the like. America has used it for star capturer, as well as heat insulating layer in Mars explorer, oil pipeline and LNG. China has also applied it to aerospace vehicle and refrigeration storage. It has very wide application prospect in aerospace, aviation, building, petroleum and petrochemical, power, energy and some other industries.
?
Feature
?
Aerogel is a kind of nanometer porous material. The diameters of its pores are less than the average molecular free path of air, so there is no air convection in the pores. It has very high porosity and low proportion of solid substance. Thus it is regarded as the solid with lowest thermal conductivity in the world. By virtue of such low thermal conductivity and good high/low temperature thermal stability, it has great potential in various heat insulating and energy saving fields.
?
Advanced technology
?
Aerogel has the common advantages of many nanometer materials, for examples, high porosity, high specific surface area, high corrosion resistance, low thermal conductivity, low density, low acoustic velocity, non-flammability, non-volatility, no moisture absorption, good environment endurance, low environmental emission, high resistance to high/low temperature, and designable structure and performance. It can be made to flexible or rigid materials of complex profile structure based on particular needs.
?
Application fields
?
It is mainly used as light high-efficiency thermal insulation materials for aviation/aerospace vehicles, ships, LNG tank, refrigeration storage, high-temperature industrial furnace, thermal batteries, oil pipeline, building wall and window/door, and so on. In addition, it can be also used as acoustic insulation materials, carriers of catalysts, absorbent, electrode and the like.
?
This material owns thermal conductivity as low as 0.030 w/m.k at 600°C. Its thin nano-mesh structure can effectively reduce the m heat conduction of solid-state, rich nano-pore structure inhibit the convection conduction of gas molecules, with functional materials absorption, reflection to the thermal radiation.
