honeycomb heat transfer

Honeycomb ceramics Honeycomb ceramic is a new developed porous industrial ceramic, it has the properties of corrosion resistances, high specific surface area, low resistance, low thermal expansion coefficient, good thermal conductivity and thermal-shock resistance performance,widely used in the industrial field,ing the advanced production technology and strict management, we have bath produce the honeycomb ceramics series,lso we can produce according customers'requirements. Material: Mullite,Cordierite,Alumina,Mullite Zirconium,Mullite Corundum,Corundum and other materials. Size: According to customers'sequirements. Hole shape: square,hexagon,rectangular,circular,triangle,diamond. Holes number: According to customers'sequirements. (1 400 holes/square inch) Application of Honeycomb Ceramics It can used as catalysts carrier for clean-up of automobile tail gas, carrier for purification system, heat retainer in the beat accumulation burner in metallurgy industry, used as structured packing, gas burning distribution plate.
