CCEWOOL 25mm ceramic fibre blanket has a thermal conductivity of air close proximity because the ceramic fiber is composed by solid fiber and air composition, porosity as high as 90%. A large number of low thermal conductivity is filled in the air vent, destroying the continuous network structure of a solid-state molecules. Thereby obtain excellent insulation properties. The smaller pore diameter, more sealed air pore along flow direction and the better insulating properties of the ceramic fibre.

     Since CCEWOOL 25mm ceramic fibre blanket is different from the conventional refractory bricks, insulating brick structure, which determines the thermal conductivity process is different. Ceramic fibers’ heat transfer is not simply from solid fiber thermal conductivity, while there are still air conduction, convection and radiation heat transfer between the walls of the hole in the gas gap.

     From the point of heat transfer, thermal conductivity generally indicates the thermal properties of 25mm ceramic fibre insulation blanket. For homogeneous materials, thermal conductivity is on behalf of its own heat property. The thermal conductivity of porous structure for ceramic fiber indicates its sum of inside conduction,convection and radiation. Therefore it is also called equivalent thermal conductivity or apparent thermal conductivity. The reason why ceramic fiber as industrial furnaces and high temperature pipe wall lining material is because it can control heat and reaching energy saving effect. The main factors affecting the thermal conductivity of ceramic fiber include following: temperature, density, slag ball, fiber diameter, fiber moisture, usage atmosphere and the fiber direction.

     CCEWOOL 25mm ceramic fibre blanket temperature degree is 1260℃ （2300℉），1400℃ (2550℉)， 1430℃(2600). Self owned raw material base, material inspection before entering factory, computer-controlled ingredient proportion system, strictly control raw material purity, therefore, manufactured ceramic fiber blanket’s shot content is 12%, which is 5% lower than similar products. Thermal conductivity reaches 0.12W/m.k and thermal shrinkage is lower than 2%.
