·Conduction heat transfer: Nanoscale fine powder, very small nano point contact heat resistance, making the effect of conduction heat transfer very small;
·Convective heat transfer: Nanoscale pores have an average of 20 nanometers, and the average free path of static air at normal temperature is 60 nanometers. Air molecules are locked in and cannot undergo micro convective heat transfer, resulting in low convective conduction efficiency;
·Radiation heat transfer: The insulation material is added with nanoscale high-temperature anti infrared substances, which reduces the radiation based heat transfer at high temperatures to ultra-low points
