The main specification of Ceramic Fiber blanket with Alu Foil: Width 300/610/1220mm, Length 3600/7200mm, blanket thickness 20/30/50mm, Alu thickness 0.047/0.2mm. Size is available for manufacture as customers’ requirements.

Thermal Insulation mechanism of Ceramic Fiber Blanket with Alu Foil:

Thermal Equipment heat rejecting channels are: Conduction, Convection, and Radiation. The Ceramic Fiber Blanket with Alu Foil weakens these heat rejecting channels and lower the heat loss to save energy.

The weakening of Heat Conduction & Transfer:

The heat passes through Ceramic Fiber Blanket. The Ceramic Fiber Blanket fibers are of no directivity and the heat conducting shall proceed along the fiber direction. So the fiber heat conduction is not perpendicular to heat surface, and it prolongs the heat transferring approach and weakens the heat conduction. Moreover, porosity of Ceramic Fiber Blanket is 93%, and 80% of the fiber contact are point ones. The point contact and porosity rate weaken the heat conductivity, enhance thermal resistance. The heat lost from the inside of Ceramic Fiber blanket is weak. The structure weakens the heat rejection obviously.

The weakening of convection heat transfer:

The porosity rate of Ceramic Fiber Blanket is high. The air is divided into almost actionless small air holes. The pressure of dispersive air hole is definite, and the air pressure with solidity fibers forms a density object screen. It rejects heat air invading and weakens heat losing; meanwhile it blocks air concection. 

The weaken of radioactive transfer:

Ceramic Fiber blankets are of white and glazed reflector with good radiation effects to heat. Meanwhile, the Alu Foil is of opacity and glaze state as the mirror reflexion mechanism. The heat rays reflex on Alu Foil. It weakens heat radiation obviously.

Ceramic Fiber Blanket with Alu Foil Application:

The structure of Ceramic Fiber Blanket with Alu Foil is of excellent heat insulation and energy saving effects. It is mainly applied in the heating furnace in Petro, Chemical, Metallurgy industry; heat insulation liner of boiler plant, external heat insulation of electrical steam pipe line, thermal-protective coating of space equipment, fire control of steamer, interlayer of building and heat insulation of daily supplies, etc.
