Honeycomb Ceramic Catalyst substrate used in cars:
Used as catalystic converters of gasoline engines, the honeycomb ceramic catalyst substrates are coated by catalyst; At the same time, we improve the specific surface areas and cut down the heat capacity to increase the atalytic function. When the noxious emissions pass through, HC, CO and NOX will be converted into harmless components.
Our ceramic honeycomb substrate has the advantages of fast burning, small volume, high mechanical strength, prominent heat-resistance, etc. It is widely used in exhaust gas purification for motorbike/vehicle. We can make 100CPSI, 200CPSI, 300CPSI, 400CPSI AND 600CPSI with various shapes, such as round, oval, racetrack and other customized shapes. We can coat them with noble metals like Pt, Pd, Rh to remove harmful gases such as CO, NOx etc that can meet emission standard: EuroII-EuroV.
>High specific surface area: Ensure exhaust gas could contact with catalyst enough.
>Stable water absorption: Guarantee catalyst could be firmly and evenly coated on the surface of substrate, so it is no waste for too thick coating.
>Warm-up characters: After starting up engine, the temperature of substrate could reach the active temperature of catalyst in the shortest time.
>Low exhaust resistance: Ask exhaust resistance of substrate to engine low, so that it will not affect the performance of engine.
>High intensity: Substrates work in bumpy cars, so the intensity of substrates must be too high to be destroyed.
>Perfect assembly: Substrates are parts of exhaust; Perfect appearance and exact dimension could ensure assembly perfect.
