Silica aerogels also known as "Blue Smoke" or "Frozen Smoke " is the lightest known solid material,and so far the best insulation materials. It contains nano-sized pore structure(100nm), and has low density(1~500kg/m³), low-k(1.1~2.5), low thermal conductivity(0.013~0.025w/(m.k)), high porosity (80~99.8%) and high surface area (200~1000 m²/g), etc.. Silica aerogels has shown the unique characteristics in mechanical, acoustical, thermal, optical and many other fields, and it has broad prospects and great applications in the aerospace, military industry, transportation, electrical appliances, petrochemical, electric power, metallurgy, construction, clothing and other fields.
Principle of Thermal Insulation for Aerogels:
The diameter of pores in aerogels is in nano grade, which is close to or even smaller than the air molecule' s meanfree path (70nm), as a result, the thermal convection vanished which results in a low thermal conductivity.
The high porosity of the material means a large number of pore walls which reflect thermal radiation, therefore, reduce the thermal transport to its limit.
The path of thermal convection in solid is along the pore walls, thus, the long pore walls lower the thermalconduction.
Comparison of aerogel nano-materials and traditional thermal insulation materials
1. Superior Thermal Performance
The thermal conductivity of aerogel is only 1/3~1/5 of common insulation,which helps to reduce heat loss and saving space.
2. Fireproof and Waterproof
Nano aerogel can reach the grade A1 noncombustible standard and the hydrophobic rate reaches more than 99%, which can avoid the material losing the thermal insulation efficiency caused by water and subsidence.
3. Long Service Life
Aerogel's three-dimensional structure which is different with other insulations inhibits sintering warpage and particles stack which may occur under hot temperature for a long time, maintains its long service life.
4. Physically Robust
Good flexibility and high tensile strength performance can resist stretching and stress from linear contraction when temperature changes.
5. Environmental Protection and Anticorrosion
Composed of inorganic materials, aerogel contains no hazard; Stripping little chloridion will cause no corrosion to the equipments and pipes.
6. Sound Insulation and Shock Absorption
Sound resistance and shock absorption make better working environment.
7. Easy To Install
Low density (<200kg/m3) and very light make it easy to cut and install.
