For thermal insulation materials, heat movement mainly has three means:
Heat Conduction：mainly finish with solid parts (particle section) in thermal insulation materials;
Heat Convection：mainly finish with air chamber in thermal insulation materials;
Heat Radiation：finish with metal gaps that have radial shield and high reflectivity.
Nano thermal insulation material is made from nano porous micro powder particles and foil-based materials that have heat shield function, and is manufactured after a special process through inorganic additives and efficient binder, its thermal insulation principles are as follows:
1）Heat Conduction: sectional area of porous micro powder particles and contact area between particles is very small; its heat conductivity is low;
2）Heat Convection: compact structure between microporous particles, the air is hard to flow within the gap, it is difficult for heat convection;
3） Thermal Radiation: multi-layer metal foil with alpha ray shield and high reflectivity can effectively cut off and reflect thermal radiation.
