Metallic Substrates for Diesel Oxidation Catalyst (DOC)

Metal Honeycomb Substrate covers these features: Ignition fast, small size, high strength, heat resistance, etc., are the most widely used in motorcycle exhaust gas purification. It is the surface
Pretreated so that metal honeycomb substrate is generated between the metal buffer layer and
The active coating layer, the thermal expansion match to address gradient between the metallic
Active coating material and the transition in the buffer layer coating containing Ce, La, Pr and
Other rare earth elements in the active coating layer, and then a load comprising Pt, Rh, etc.
Made of a noble metal of the active ingredient.

Metal honeycomb substrate advantages:
1) Vector buffer layer surface treatment, the coating is firmly combined;
2) Using high temperature resistant material than the high surface area and good catalytic
Converter temperature performance;
3) Optimizing the ratio of precious metals and rare earth elements, catalytic converter light-off temperature is low;
4) High-performance oxygen storage material formulations, high purification efficiency of catalytic
Converters;
5) Used for metal substrate automatic coating apparatus, the coating uniformity;
6) Metal catalytic converters long life: Gasoline vehicles up to 120, 000km;
7) Strict quality control and inspection, product quality and stability;
8) Different cost formulas to choose from, both emissions compliance colleagues economy.
