Honeycomb Ceramic Substrate
The usual CPSI for honeycomb ceramic substrate is 400. 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. High specific surface area, low pressure drop, rapid light-off time and reliable & durable performance are achieved through high cell density of 400, 500 and 600CPSI. All of these make our ceramic honeycomb an ideal catalyst substrate media for oxidation & reduction catalyst. At present, our typical substrate are available in a variety of sizes with the different shapes, such as: Round, elliptical, race track and so on.
Auto ceramic catalytic converter substrate 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. We can produce honeycomb ceramic substrate with different specification and differnt cars for the car converter as the customer requests. The ceramic substrate is made of cordierite, and it is used for car catalytic converter. The shape will be round, oval or racetrack.
Advantages
*Low thermal expansion coefficient
*High porosity of hole on the wall, good liquidity and uniform distribution
*High temperature resistance, chemical corrosion resistance, thermal shock resistance and thermal shock resistance is strong
*The pressure drop is small.
*Cold start performance is good, low light-off temperature, high conversion efficiency
Applications
Iron, garbage incinerator and waste gas treatment thermal equipment, chemical plants, smelters, industrial boilers, gas turbines, power plants, power engineering and heating equipment, ethylene cracking furnace etc.
