Honeycomb Ceramic Description:
Honeycomb ceramic is new developed ceramic part.
Because of it's features of corrosion resistances, large specific surface area, small heat resistance, good thermal conductivity and excellent thermal-shock resistance, fast heat exchanging and energy saving. It's widely used in many fields.
The honeycomb ceramic as the heat exchange media is the key part for heat storing HTAC ( High Temperature Air Combustion) technology. It is the best choice for RTO, heat exchanger and other environmental protection and energy saving products.
The honeycomb ceramic as heat exchange media is the key part for heat storage HTAC(High Temperature Air Combustion) technology, which has been widely applied in all kinds of pushing-steel heating furnace, RTO(Regenerative Thermal Oxidation), stepping heating furnace, heat treatment furnace, forging furnace, dissolving furnace, steel wrapping/middle wrapping baking apparatus, soaking pit, radiation tap incendiary apparatus, covering furnace, high temperature hot-blast stove in metallurgical machine building and all kinds of ceramic cellar stove, glass cellar stove in building materials, and all kinds of tap heating stove, splitting stove, other industrial stove cellar, too.
Honeycomb ceramics as heat storage body, by the advantage of large specific surface area, small heat resistance, good thermal conductivity, excellent thermal shock resistance, realize quickly exchanging heat; Reducing energy in the strict sense (up to 97% of true thermal energy can be recovery and also it can absorb NOx more than 40%).
Application
*As support of catalyst, ceramic honeycomb materials are typically used for purifying automotive emission, removing bad smell etc, for instance, utilized in exhaust catalytic converter, air- fresher machine for hotel, restaurant, toilet and so on
*Heat transfer agent: It can save 12% of energy in heat exchange, and it mainly utilized in heat recovery unit of RTO. Refractory stove: Low mass/volume, fast heat conduction. Gas burn distributing plate: Complete burn, energy saving is 10%
*As filtrate substrate, they are generally utilized in food processing, environmental industry, metallurgical industry etc. For filtering particulate in industrial waste gas and bubble in liquid of molten melt and making the molten melt laminar so as to increase casting yields, also filtering impurities in juice, dextrose and sucrose etc
Advantages:
*High thermal shock resistance
*Low thermal expansion and good thermal conductivity
*Optimized flow rate
*Low pressure drop
*Excellent chemical and high geometric surface area
*Very long functional life
*Strong production capacity and leading technology level
*ISO9001: 2008 Certificate
