Thermal Shop Honeycomb Keramik

Honeycomb thermal store catalyst ceramic is used for waste gas treatment(RTORCO) of the different requirements, selecting many kinds of new highly effective ceramic material to make. It has the following notable characters: large specific surface area, little resistance loss, small heat-expand and cold-contract coefficient, high water-absorbing ratio, good fracture resistance and moderate Millipore aperture. 1Physical & chemical properties of honeycomb thermal store catalyst ceramic: MaterialItemAlumina CeramicLoosen MulliteCompact CordieriteLoosen CordieriteStoneware PorcelainAL2O3(%)52.068.325.535.430.4SiO2(%)43.328.957.251.566.1MgO(%)0.10.27.911.50.13Other(%)<3.5<2.0<3.0<1.5<3.0Material Densityg/m32.682.312.422.162.47Loose DensityKg/m3965832871778889Coefficient of Thermal Expansion×10-6/°C6.26.23.53.44.8Specific CapacityJ/Kg K9929989421016897Thermal ConductivityW/Mk2.792.421.891.631.37Resistance to Fluctuated TemperatureKMax 500Max 550Max 500Max 600Max 500Softening Temperature°C15001580132014001380Highest Working Temperature°C14001480120013001280Average Thermal CapacityKWh/m3K0.2660.2310.2280.2190.222Porosity Ratio%0.826.00.415.00.6Acid Resistance%0.22.55.016.70.3 2Specification of honeycomb thermal store catalyst ceramic: Outside Dimension150×150×300(mm)Number of Hole(cells)25×25=62540×40=160050×50=2500Aperture(mm)4.93.02.4Thickness of Inner-wall(mm)1.00.70.6Specific Surface Area(m2/m3)5408251050Cell-opening Ratio(%)676463
