Ceramic honeycomb series:
Honeycomb ceramic is mainly used as the catalyst substrate and medium for heat exchange, and widely applied to metallurgy, chemistry and industry tower packing, heat recycle equipment of RTO system, industrial gas treatment, vehicle exhasut gas treatment, purification system for removing NOx of smoke of power plant, purification system for harmful gas of garbage burning, and harmful gas purification of mining industry and chemical industry.
Honeycomb ceramic substrate for vehicle: Its major material is composed of cordierite and stainless steel of iron, chrome and aluminium, usual hole density is 100csi, 200csi, 300csi, 400csi and 600csi, and it can be coated with noble metal (PT, Pd and Rh)to reach European norm 2, 3 and 4 emssion standard.
