Why is the thermal insulation effect of nano thermal insulation board so good

Date:2016/8/25 source:ldvaugusta.com Number of visits:1348

The nano heat insulation board adopts special nano inorganic refractory powder, the contact between the nano particles is extremely small point contact, 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 nano microporous heat insulation material 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 paint, so that the micro convection heat transfer effect between the molecules of the static air is eliminated, and the normal temperature heat conductivity coefficient of the nano heat insulation board is lower than that of the static air.
At high temperature, the main role of heat transfer is heat radiation. nano heat insulation board added special infrared additives to prevent and reflect infrared at high temperature, the radiation heat transfer effect to the lowest point, make the material at high temperature radiation heat transfer coefficient to the lowest value.
The thermal insulation performance of the novel nano heat insulation board is four times better than that of the traditional fiber heat insulation material, so far, the nano heat insulation board has the best thermal insulation performance
