- With economic growth and urban expansion,Car ownership in the world is increasing rapidly.Motor vehicle exhaust has become one of the main factors of the deterioration of urban air。Also has a great impact on human and ecological environment.
Automobile exhaust catalytic converter is used to eliminate harmful substances in motor vehicle emissions,The tail gas purifier uses honeycomb ceramic carrier to coat precious metals and rare earth elements. CO, NOx, HC and other harmful components in the tail gas are converted to CO2, H2O and N2 by the redox reaction.Emission standards to meet the requirements of the state.The catalytic converter can be installed on new engines or retrofits,and exhaust gases filtration system for generator sets.
The ceramic fiber sealing mat is one of the key parts of the catalytic converter,which is installed between the metal shell and the ceramic substrate,the main function is to protect the core of the catalytic converter: the honeycomb ceramic substrate.
Excellent heat resistance
Compared with the metal mesh, ceramic fiber sealing gasket shows superior thermal insulation performance, which can reduce the temperature of the catalytic converter, which can eliminate the need of auxiliary heat shield, and can also improve the durability of the catalyst.
Prevent gas leakage
Under normal operating conditions, ceramic fiber gasket can provide carrier and the shell almost does not leak sealing. Leakage of gas gap will make catalytic converter useless.
Moderate expansion force and softness
The ceramic fiber seal gasket provides a suitable expansion force for the position of the carrier of the catalytic converter, which is capable of supporting the soft ceramic fiber material and shows a remarkable and lasting support force.
Sound insulation
Compared with metal mesh, ceramic fiber gasket has sound deadening effect, noise control to improve the exhaust system.
