Tianjin nano insulation board supplier hot metal ladle and ladle insulation backing board

The thermal insulation performance of the new nano thermal insulation board is four times that of the traditional fiber thermal insulation material
It is a material with good thermal insulation performance so far
Nano insulation board has won the favor of many industries because of its lightweight advantages
In this era of pursuing efficiency, production efficiency is very important
However, if the key insulation layer of high-temperature equipment is very thick, the capacity of the equipment will be reduced, the capacity will be reduced, and the natural efficiency will be reduced
The nano insulation board greatly reduces the thickness of the insulation layer and provides greater space capacity for the equipment

Nano thermal insulation board adopts special nano materials
The contact point between nanoparticles is very small, and the thermal resistance of point contact is very large, which makes the thermal conductivity strain of the material very small, resulting in the thermal conductivity of nano microporous thermal insulation material very small
A large number of nanopores are formed between nanoparticles, with an average size of 20 nm
At room temperature, the average free motion path of molecules in static air is 60 nm
Air molecules are locked in the nanopores of the coating, and the small convective heat transfer between static air molecules disappears
Therefore, the thermal conductivity of nano insulation plate at room temperature is lower than that of static air
At high temperature, the main function of heat transfer is heat radiation
Special infrared additives are added to the nano insulation board to prevent and reflect the infrared at high temperature, and reduce the radiation heat transfer effect to the point, so as to reduce the radiation heat transfer coefficient of the material at high temperature
