Technique Principle of Nano Thermal Insulation

For thermal insulation materials, heat movement mainly has three means:

1. Heat Conduction: mainly finish with solid parts (particle section) in thermal insulation materials;

2. Heat Convection: mainly finish with air chamber in thermal insulation materials;

3. 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.
