Product Description

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. Automobile exhaust gases are conventionally purified with a catalyst supported on a ceramic body able to withstand high temperatures. The preferred catalyst support structure is a honeycomb configuration which includes a multiplicity of unobstructed parallel channels sized to permit gas flow and bounded by thin ceramic walls. The walls of these channels provide the surface for precious-metal catalysts that convert noxious emissions into carbon dioxide, nitrogen and water vapor. We can provide honeycomb ceramic substrate has been coated and non-coated precious-metal.

Honeycomb ceramic substrates are honeycomb-like structures with thousands of parallel channels. The walls of these channels provide the surface for precious-metal catalysts that convert noxious emissions into carbon dioxide, nitrogen and water vapor. Honeycomb ceramic substrates enable highly efficient emissions control systems by offering:
*High surface area
*Low pressure drop
*Rapid light-off
*Thermal-mechanical durability
*System cost efficiency
*High transforming efficiency

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

Advantages:
*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
*Warm up characters: 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 dimension could ensure assembly perfect
