The ceramic filter plate is extremely vital to the quality of aluminum melt, which affects the subsequent processing performance and the quality of the final product to a large extent. All countries in the world attach great importance to the purification of aluminum melt.. Aluminum pollution reasons for numerous reasons, in the process of smelting, on the one hand, in the molten or partially molten state of blast furnace in the atmospheric exposure of aluminum, easy oxidation, easy to react with water vapor and hydrogen absorption, easy to form various forms of non-metallic inclusions (such as furnace, lining, chlorine, carbon and other traffic) and particle coarse metal interaction and so on. On the other hand, some non-aluminum impurity parts are charged for garbage in the circulation process. Because of the process of waste, factory waste factory waste, the way is different, the composition is complex, and the quality is poor. These impurities will make continuous casting billet bubbles, inclusions, gravely affect the purity of the metal melt, thereby further affecting the processing properties, mechanical properties, corrosion resistance and appearance quality.
Alumina foam ceramic filter plate my company can effectively remove all kinds of fineness reaches micron aluminum water inclusions, stable laminar flow aluminum water shift, is conducive to filling; it has a rare mullite corundum structure, superior mechanical strength and chemical stability, excellent aluminum water erosion performance; strict control of pore size and porosity, stable ceramic filter plate on the filtration effect; the ceramic fiber pad is sealed around the ceramic filter plate, which helps to seal the filter box of the filter plate to ensure that there is no metal liquid side flow. The product IS mainly used in the production of aluminum and aluminum alloy purification process, also used in a variety of gas-solid, liquid-solid separation medium, catalyst support, burner and sound absorption and environmental protection fields.
Other applications of Ceramic Foam Filtration Slice:
Copper alloy casting filtration, non-ferrous metal (brass, copper, zinc, tin) melt in the pouring process, will also produce oxidation and non-metallic impurities. There is a lot of garbage, if the use of foam ceramic filter plate can considerably reduce the rejection rate. Cordierite is normally used for copper alloy melt filtration, and the mesh size is 1 to 1.2mm.
Catalyst carrier for automobile exhaust purification treatment
With the continuous development of China's automobile industry, automobile exhaust emissions have become the main source of environmental pollution. Due to its large specific surface area, excellent thermal stability, wear resistance, low density, low density, foam ceramic has been used as a carrier for automotive exhaust catalytic converters. By installing the catalytic converter in the exhaust pipe of gasoline vehicle, the CO, HC, NOx harmful gases in the exhaust gas of gasoline vehicle can be CO2, H2O, N2, and the conversion rate can reach more than 90%. Used in diesel vehicles, in excess of 50% carbon particulate clearance rate. When the foam ceramic filter particles are filled with carbon particles, catalytic oxidation or electronically controlled burning processes can be used to eliminate carbon particles and achieve long-term use.
In the special field, in the elevated temperature application, the ceramic filter plate has excellent thermal radiation characteristics, and is used in the heat transfer, multi-hole medium combustion technology. The effect is remarkable. Foam ceramics can also be made into photocatalyst support, nano titanium dioxide, UV light excited foam ceramic carrier coating, has a strong photocatalytic oxidation degradation of organic matter and microbial characteristics and catalytic degradation, purification of air. Ceramic filter plates can also be made into chemical tower packing, gas material, gas burner combustion energy plate, etc.
