The Jinshi energy-saving nano heat insulation board adopts special nano-scale inorganic refractory powder, has huge specific surface area, the contact between the nano particles is extremely small point contact, and the thermal resistance of the point contact is very large, so that the conductive heat transfer effect of the material is very small, and the conductive heat transfer coefficient of the energy-saving nano heat insulation board is very small; A large number of nano-scale pores are formed between the nano particles, the average size of the nano-scale pores is 20 nanometers, and the average thermal motion free path of the molecules of the static air at normal temperature is 60 nanometers, so that the air molecules are locked in the nano-scale pores of the powder, and the small convection heat transfer effect between the molecules of the static air is eliminated, so that the thermal conductivity of the gold stone energy-saving nano heat insulation board at normal temperature is lower than that of the static air; At high temperature, the main role of heat transfer is thermal radiation, Jinshi energy-saving nano thermal insulation board added a special infrared additives, at high temperature to prevent and reflect infrared rays, the radiation heat transfer effect is reduced to the lowest point, make the material at high temperature radiation heat transfer coefficient is reduce to the lowest value.
