Metal Honeycomb Substrate Introduction:
Metallic substrate is with the advantages of fast burning, small volume, high mechanical strength, prominent heat-resistance, etc. It is widely used in exhaust gas purification, especially for motorbike. Firstly metallic substrate should be pretreated in order to generate a transition layer which is required to solve the mismatched heat expansion between metallic substrate itself and the active layer. On the transition layer, it is coated with rare earth catalyst, while in active layer is coated with noble metal like Pt, Pd, Rh.
The catalytic converter is coated with rare earth element and noble metals of Pt, Pd, Rh. When the engine exhaust passing through the three-way catalytic converter the elements of CO would be oxidized into CO2, the HC is turned into H2O and CO2, while the NOX is deoxidized into nitrogen. The catalytic converter substrate is made of metal honeycomb with stainless steel crust and Fe-Cr-Al honeycomb body; It is a critical part of motorcycles and off-road engines to make the exhaust emission meet government standard.
Remark: We can supply Metallic Substrate coated with noble metals of Pt, Pd and
Rh, and we also offer Metallic Substrate without precious metals.
