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. Automobile exhaust gases are conventionally purified with a catalyst supported on a ceramic body able to withstand high temperatures. The preferred catalyst support structure is a honeycomb configuration which includes a multiplicity of unobstructed parallel channels sized to permit gas flow and bounded by thin ceramic walls. The walls of these channels provide the surface for precious-metal catalysts that convert noxious emissions into carbon dioxide, nitrogen and water vapor. We can provide honeycomb ceramic substrate has been coated and non-coated precious-metal.
