OEM Auto / Truck Parts Silicon Carbide Based Honeycomb Ceramic Diesel Particulate Filter for Catalyst Converter DPF

Product Description

DPF carriers are mainly made of ceramic and metal based materials.
Ceramic based DPF carrier materials include cordierite, silicon carbide, mullite, zirconia, etc. These materials have good high-temperature stability, chemical stability, and mechanical strength, and can effectively capture and store particulate matter.
Metal based DPF carrier materials include sintered metal, foam metal, metal wire mesh, etc. These materials have a high specific surface area and good thermal conductivity, which is beneficial for the capture and regeneration of particulate matter.
At present, the most commonly used filter materials are cordierite and silicon carbide. These two materials are widely used due to their excellent performance, among which cordierite has a certain advantage in the market due to its lower cost and good filtration effect. Silicon carbide, on the other hand, is more suitable in some special application scenarios due to its higher high temperature resistance and chemical stability
Diesel particulate filter based on cordierite
The advantages of cordierite (DPF) mainly include its suitability for purifying diesel exhaust particulate matter (PM), good oil adaptability, and relatively low cost.
Suitable for diesel engine exhaust particulate matter purification: The cordierite DPF, as a special structure honeycomb ceramic filter with wall flow, is mainly used in diesel engine exhaust particulate matter (PM) purification devices. It utilizes the pores on the wall of the wall flow filter to intercept solid particles in the diesel engine exhaust, thereby purifying the diesel engine exhaust.Product Parameters
