Theory of Microporous Board
There are three transmission routes of heat: conduction heat transfer, convection heat transfer and radiation heat transfer, The unique property of nano thermal insulation materials comes from its unique nanoscale microporous structure.The nanoporous structure, which has been scientifically and rationally designed, has been optimized in the following three ways.
The powder particles of nano thermal insulation materials are very small, the primary particles are about 7nm, the contact area of solid particles are very small, so make the effective thermal resistance through the conduction heat transfer very large, which leads to very low effect of conduction heat transfer.
Convection heat transfer:
The nano particles of nano thermal insulation materials are aggregate, the micropore diameter formed inside of materials is around 20nm, however the thermal motion free range of gas molecules retained in the materials is about 60nm at room temperature, so each gas molecule is locked inside the individual pore and can not collide with other gas molecules, the convective heat transfer of gas molecules generated from this way is also limited at minimum value, so that the convective heat transfer inside the nano thermal insulation materials is almost negligible.
Radiation heat transfer：
The effect of radiation heat transfer is very huge, the nano thermal insulation material is added with heat resisting anti-infrared ray fines, such anti-infrared additive causes infrared ray be farthest blocked and reflected back to heat resource occurred place, thus the radiation heat transfer effect of thermal insulation materials is very small.
In conclusion, the nanoscale micropore structure and additive of nano thermal insulation materials developed by newest nano technology lead to the three routes of heat transfer changed radically, the heat transfer effect in the role of nanoscale micropore goes into minimum value, so the nano micropore thermal materials with excellent thermal insulation performance are made.
