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.

Honeycomb Ceramic Catalyst Substrate DPF (Diesel Particulate Filter)


Diesel particulate filter bases on honeycomb ceramic substrate, whose materials are cordierite or carborundum. It could trap the particulate matter from disel exhaust emissions, so they are applied on cars, buses, trucks and so on.

Advantages:
>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.
