Honeycomb Ceramic
Products Description
Honeycomb ceramic is composed of many small holes, and its structure is similar to the honeycomb. It is usually composed of alumina, silicate, and other additives, and a honeycomb -shaped channel structure is formed through a special processing process. These tracts can provide a large number of surfaces, thereby enhancing their functions such as catalytic reactions, filtration and adsorption. Honeycomb structured ceramics can be divided into four categories: heat storage, fillers, catalytic vector and filter materials. Honeycomb ceramic heat storage heat capacity is above 1000kj/kg, the highest use temperature of the product ≥1700 ° C, and can save more than 40%of the fuel in the kiln of the heating furnace, baking, average heat furnace, and cracking furnace. The temperature of the flue gas is less than 150 ° C.
Features
Honeycomb ceramic have a high comparison area and strict tiny pores, and have excellent physical and chemical properties, such as high strength, corrosion resistance, high temperature resistance, low heating coefficient, high compression strength, etc.
Application
In industrial applications, cellular ceramics are usually used in automotive exhaust gas purifiers, industrial exhaust gas treatment equipment, thermal power plants and petrochemical equipment. In these applications, honeycomb ceramic can be used as a carrier, used to fix and disperse the catalyst, and can also be used as filtering medium to improve the efficiency of exhaust gas treatment. In addition, honeycomb structured ceramic can also be used to make high -end ceramic products such as gas stove, high -temperature sagger, and aviation engine nozzle.
