Foamed metal for automotive exhaust gas filter catalyzer carriers
Foam Metal Carrier Catalyzer for Motorcycle Exhaust Filtration
Foam metal carrier catalytic converter has the advantages of quick ignition, small size, high strength, good heat resistance, etc., and is used in motorcycle exhaust gas purification. It is pre-treated on the surface of the foam metal carrier carrier, while a transition layer is generated between the foam metal carrier and the active coating to solve the thermal expansion matching gradient transition between the metal material and the active coating, and the active coating containing rare earth elements such as Ce, La, Pr, etc., is coated on the transition layer, and then made by loading the active component containing precious metals such as Pt, Rh, and so on. Carrier surface treatment to generate the transition layer, the coating of the combination of good firmness; the use of high surface area materials, catalytic converter performance; optimization of the precious metals and rare earth elements, the catalytic converter ignition temperature is low; the use of oxygen storage material formulations, catalytic converter purification; the use of automatic coating equipment for metal honeycomb carriers, the coating uniformity is good; the metal catalytic converter service life is long: gasoline vehicles can reach more than 80,000 km; strict quality control and inspection, product quality and stability; strict quality control and inspection, product quality and stability. Strict quality control and inspection, product quality is stable; different formulations are available, emission standards and economy at the same time.
Foam metal has the following advantages over cellular ceramics.
1. Foam metal has the characteristics of metal, deformable, anti-vibration, which improves the service life of automobile and motorcycle exhaust three-way catalytic converter.
2. Foam metal has better performance and thermal shock resistance than ceramic foam.
3. Foam metal has a three-dimensional porous structure, with a larger surface area per unit volume and better filtration effect.
