The ceramic substrate is made of cordierite, The cells density can be 100 cpsi, 300 cpsi, 400 cpsi or 600 cpsi. The usual cpsi (Cell Per Square Inch) for catalytic converter substrate is 400, the shape of ceramic substrate is round, racetrack, ellipse and other special shape according to the customer's requirement.
The ceramic substrate is made of cordierite, and it is used for car catalytic converter. The cells density can be 100 cpsi, 300 cpsi, 400 cpsi or 600 cpsi. The shape will be round, oval or racetrack. We can supply both ceramic element coated with noble metals of PT, Pd, Rh and ceramic element without noble metals.
Application
*As support of catalyst, ceramic honeycomb materials are typically used for purifying automotive emission, removing bad smell etc, for instance, utilized in exhaust catalytic converter, airfresher machine for hotel, restaurant, toilet and so on.
*Heat transfer agent: It can save 12% of energy in heat exchange, and it mainly utilized in heat recovery unit of RTO. Refractory stove: Low mass/volume, fast heat conduction. Gas burn distributing plate: Complete burn, energy saving is 10%.
*As filtrate substrate, they are generally utilized in food processing, environmental industry, metallurgical industry etc. For filtering particulate in industrial waste gas and bubble in liquid of molten melt and making the molten melt laminar so as to increase casting yields, also filtering impurities in juice, dextrose and sucrose etc.
