Ceramic honeycomb

 

It is one kind of industrial porous ceramics, many passable parallel channels are ramified over its inside.

 

Each individual part made up of these honeycomb ceramics are constructed into the shape with square cells at two ends. 

 

Compared with ordinary ceramic materials, they are characterized by low heat expansion ratio, high thermal shock resistance, large specific surface area, anticorrosion etc .

 

Ceramic honeycomb

 

regenerator is the key and core component on high temperature air combustion technology. It has large specific area, specific heat, low coefficient of thermal expansion.

 

Ceramic honeycomb Application:

 

 

It  can be used as heat-exchanger and apply into the RTO of heat recovery devices .

 

It can be used as catalyst supporter to purify Automobile exhaust and remove

abnormal flavour of gas.

It can be used as filters  and apply to food service industry, environmental protection industry and Metallurgical Industry .
