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. Used as catalytic converters of gasoline engines, the honeycomb ceramic catalyst substrates are coated by catalyst; At the same time, we improve the specific surface areas and cut down the heat capacity to increase the catalytic function. When the noxious emissions pass through, HC, CO and NOX will be converted into harmless components.
Automobile exhaust catalyst carrier's coefficient of thermal expansion can be controlled at 1.1 × 10-6, the average pore diameter, 8-10μ M, hole wall thickness 0.15-0.17mm, reached domestic leading level, fully meet various automobile exhaustuse of the catalyst carrier requirements. As a the ceramic honeycomb national standard formulation of one of the units, we successfully developed the technology to reduce the the product thermal expansion coefficient, pore structure and pore wall.
Features:
*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
