Insulation principle of ceramic fiberboard
Feb 09, 2018

Because the porosity of the ceramic fiberboard is very high, so the gas is divided into a small Concan by the fiber, at this time, because the pressure in the dispersed porous silos is certain, the air pressure will be with the solid fiber to form a dense physical shielding barrier to the intrusion of hot airflow.

On the conduction and heat transfer of ceramic fiberboard, because the fiber staggered not clear directionality, so the solid heat conduction can only follow the direction of the fiber rod to stop, so the thermal conductivity of the fiber is not complete perpendicular to the hot surface, thus extending the transmission path, another 80% of the fiber is point contact, further increase the conduction heat transfer heat resistance, The final result is that the thermal conductivity of the fibers in the heat-resistant fibers is not obvious.
