Production Description:

Product density (g/m2) Average thickness (mm) Clearance applicable (mm) 2600 4.15 2.36-2.60 3100 4.90 2.82-3.10 4070 6.02 3.70-4.70 Overhigh temperature to the influence of the catalytic converter * Reduce the pressure to the cushion * Reduce the intensity and rigidity of metal shell * Increase the clearance between metal shell and ceramic substrate, aggravate the distortion of metal shell * Increase the damage of the cushion, shorten the working life 　 Designing of the substrate of catalytic converter * Designing principle of the substrate shape. 1.Exert catalyst’s highest efficiency. 2.Transverse temperature of the substrate is smallest. 3.Make hermetic pressure distribute evenly. * Length of the substrate 76mm-152mm. * Honeycomb wall thickness of the substrate 0.1-0.2mm . density after canning= weight of original insulating mat clearance between shell and substrate Function of insulating mat * Function of insulating mat * Fixation of crispy ceramic substrate * Amortizing fission due to different heating inflation coefficient of metal can and ceramic carrier * Airproof and preventiing waste gas leak * Heatproof and avoiding overheating of the shell * Sound insulation and noise reduction * Protecting ceramic carrier away from effecting by the out force and shock * Excellent airproof performance and ensuring all harmful gas to pass through catalyst carrier fully and reaching high purification effect
