ceramic honeycomb filter apply to metal liqiud filtration. with high achievable surface areas, low thermal expansion, excellent thermal shock resistance and high compr-essive strength. have function as: 1. mechanic deterring: remove big oxide mutated function: calm down turbu-lent laminar flow. 3.absorbing function: the myriad eyelets which only been found in microscope can absorb smaller impurities, make more excellent metal products. 4.contact action: the special exact square and the triangle bore eye apperance design promote to oxidize miscellaneous quality to absorb dintfe. Honeycomb ceramic substrate is used as a carrier in a three way catalytic converter for automobile industry with its special large surface area. The product can load enough noble metal and other catalytic reactive components, making the Carbon Monoxide (CO), Hydrocarbons (HC), Nitrogen Oxides (NOX) in car exhaust emitted after purifying. Meanwhile, the wall-flowing type of filter with porosity and thin wall is able to filter particulates in the diesel exhaust gas (about 500 degree celsius). Honeycomb ceramic heat accumulation substrate has low heat expansion coefficient, large surface area,good heat stability and anti-corrosion. our products comply with USA and European standard, widely used for high temperature accumulation and exchange in industries waste gas treatment for metallurgical,chmical and even construction materials. typical application fields: 1.Purification system in the smoke of the thermal power plant. 2.Harmful gas purification system in rubbish burning. 3.Toxic gas purification system in chemical and mining industries. 4.Slag filter in casting and foundry industry. 5.Catalyst substrate,stuffing material for chemical industry columns and contact combustion.
