Ceramic Honeycomb Substrate
Honeycomb ceramic is new developed ceramic part. Because of it's features of corrosion resistances, large specific surface area, small heat resistance, good thermal conductivity and excellent thermal-shock resistance, fast heat exchanging and energy saving. It's widely used in many fields. The honeycomb ceramic as the heat exchange media is the key part for heat storing HTAC ( High Temperature Air Combustion) technology. It is the best choice for RTO, heat exchanger and other environmental protection and energy saving products.
We can make honeycomb ceramic various material. Like alumina, multiple cordierite etc. The usual cells density for honeycomb ceramic substrate is 400 CPSI.The shape of honeycomb ceramic is round, racetrack, ellipse and other special shape according to the customer's requirement in order to meet the different cars models requirements. Our company can offer honeycomb ceramic substrate with different specification and different cars for the car converter as the customer request.
Honeycomb ceramic substrate is made of cordierite, and it is used for car catalytic converter. We can supply both ceramic element coated with noble metals of Pt, Pd, Rh and ceramic element without noble metals.
*The honeycomb ceramic substrate have a very competive substrates.
*We can produce 100CPSI, 200CPSI,400CPSI,600CPSI can be in the shape of round ,racetrack and ovral.
*Specification can be customerlized, as the the customers requirement.
*Can be coated with the catalyst and the noble metal as the customers emission standards:Euro II, EuroIII and EuroIV and EPA standard and the Cariforlia standards.
Honeycomb Ceramic Substrate
The honeycomb ceramic substrate used in cars, and work as catalytic converter core of Car Emission Systeme. We can be ustomized as per clients' requirements
The characteristic of honeycomb ceramic catalyst substrate used in cars as follows
*High specific surface area: ensure exhaust gas could contact weigh catalyst enough
*Stable water absorption: guarantee catalyst could be firmly and evenly coated on the surface of substrate, so it's no waste for too thick coating
*Fast in temperature rising: 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 won't 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
