Description
Honeycomb ceramic is combined wth parallel、consistent and uniformly distributed honeycomb cells. t is
made of cordierite,mullite- cordierite,mullite,corundum mulite,corundum,silicon carbide
alumina,stoneware and others with different materials, sizes and shapes. They have low heat expansion
large surface area,good thermal shock resistant,low pressure drop, low thermal resistance, good thermal
conductivity characteristics compared with ceramic balls and ceramic saddles. As the core component of High
Temperature Air Combustion Technology(HTAC) in the recovery of waste heat, promote efficient combustion,
greatly reduce the emission of NOx. RTO honeycomb blocks has been completely replace other ceramic parts
in the purification RTO device and RCO device. The ceramic honeycomb has been widely used in metallurgy,
chemical petrochemical, construction, power plant, mineral, mechanical, environmental and civil industries,
because of its excellent performance in energy saving and environmental protection.
Pingxiang Zhongci Ceramic Material Packing Manufacture was established n 2014, has been successfully engaged
in the fields of mass transfer for about thirty years. We are the class-1 supplier of Sinopec、CNPC、CNOOC
and Sinochem Group and other large enterprise.As a member of China Nationa association of innovation, we
are also cosely related with several famous universities and institutes with the best ceramics laboratories. With
the strong capial and technical strength,standardized management, as well as years of cooperation with
experts and professors from scientific research institutions and famous universities, we set up an advanced
production line of honeycomb ceramic. With specific material processing method and unique production
process,we carry out the products with high specifc heat capacity,high surface area,good thermal
conductivity, thermal shock is greatly improved, which greatly prolong the product life.We can provide the best
cost-effective honeycomb ceramic blocks.
