Product Description

Honeycomb ceramic
Honeycomb ceramics are a new type of ceramic product with a honeycomb shape. It is widely used in the chemical, electric power, metallurgy, petroleum, electronic appliances, machinery and other industries for the first time in the purification of small vehicles. It is more and more extensive and the development prospects are considerable. Honeycomb ceramics are composed of numerous equal pores. The maximum number of holes has reached 120-140 per square centimeter, the density is 0.3-0.6 grams per cubic centimeter, and the water absorption rate is up to 20%. Due to the characteristics of porous thin wall, the geometric surface area of the carrier is greatly increased and the thermal shock resistance is improved. The products are meshed with triangles and squares, the triangle is much better than the square, and the number of holes is much larger. This is especially important as a catalytic carrier.

Material
Honeycomb ceramics can be made from a variety of materials. The main materials are: cordierite, mullite, aluminum titanate, activated carbon, silicon carbide, activated alumina, zirconia, silicon nitride and cordierite-mullite, cordierite-aluminum titanate and other composite substrates.

Properties
Environmentally friendly ceramics Ceramic materials can be widely used in various environmental protection fields due to their high strength, high temperature resistance, corrosion resistance and wear resistance, such as automobile exhaust emissions. As a filter material, honeycomb ceramic has the following advantages: good chemical stability, acid and alkali resistance and organic solvent; excellent resistance to rapid heat and rapid cooling, working temperature up to 1000 ° C; good antibacterial property, not easy to be degraded by bacteria, not easy to block and easy Regeneration; strong structural stability, narrow pore size distribution, high permeability; non-toxic, especially suitable for food and drug treatment.
