Cordierite Honeycomb Ceramic for RTO 150x150x300mm
Detailed Product Description
| Brief Introduction |
Ceramic honeycombs are a new kind of industrial ceramic product developed in recent years. They have a large surface area, higher air vent rate, good heat functions, stable chemical properties etc. At present, ceramic honeycombs are being used to purify industrial waste gas, automobile emissions, eliminate noise, deal with waste water, to dry air, incineration, used in the manufacture of infrared ray instruments, to filter metal liquids etc. All ceramic honeycombs can be produced in conformance with customer requests. As heat exchange media, ceramic honeycomb are mainly used in heat recovery unit of RTOs. |
Ceramic honeycomb used for RTO application
Cordierite is a magnesium alumina silicate material, which has very low linear expansion, low coefficient of thermal expansion and excellent resistance to thermal shock. Cordierite also offers an excellent range of mechanical strength, porosity criteria, and excels in cost-effective extruded and dry-pressed forms.
Cordierite Honeycomb Monoliths are divided into two types:porous type and compact type.
