Honeycomb ceramic substrate is made of cordierite, and it is used for car catalytic converter. We can supply both ceramic elementcoated with noble metals of Pt, Pd, Rh and ceramic element without noble metals. 1. The honeycomb ceramic substrate have a very competive substrates. 2. We can produce 100CPSI, 200CPSI,400CPSI,600CPSI can be in the shape of round ,racetrack and ovral. 3.Specification can be customerlized, as the the customers requirement. 4.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
|
| Advantage of honeycomb ceramic block: 1. High specific surface area: ensure exhaust gas could contact weigh catalyst enough. 2. 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. 3. Warm up characters: after starting up engine, the temperature of substrate could reach the active temperature of catalyst in the shortest time. |
