Honeycomb ceramic is a newly developed porous industrial ceramic. The honeycomb ceramic catalyst substrate for automobiles is made of cordierite and is used in automotive catalytic converters. The cell density can be 100 cpsi, 300 cpsi, or 400 cpsi. The shape will be a circle, an oval or a racetrack. We can provide ceramic components plated with precious metals such as Pt, Pd, Rh, and ceramic components without precious metals. When toxic emissions pass, HC, CO and NOX will be converted into harmless components.

catalyst converter working principle

Properties:

1. Excellent high-temperature resistance, corrosion resistance, excellent thermal shock stability, high mechanical strength, large heat storage capacity, good thermal conductivity, and energy greatly improve the preservation effect and service life.

2. High specific surface area: to ensure that the exhaust gas can fully contact the weighing catalyst.

3. Stable water absorption: to ensure that the catalyst can be firmly and evenly coated on the surface of the substrate, and the coating is too thick and not wasteful.

4. Warm-up characteristics: After the engine is started, the substrate temperature can reach the active temperature of the catalyst in the shortest time.

5. Low exhaust resistance: The exhaust resistance of the substrate to the engine is required to be low, so as not to affect the engine performance.

6. High strength: The substrate works in a bumpy car, so the strength of the substrate must be too high to be destroyed.

7. Perfect assembly: The base plate is the exhaust part; the perfect appearance and precise size can ensure the perfect assembly.
