alumina陶瓷过滤器泡沫

alumina eramic foam filter is been made by specific procedures and have peculiar bone-frame holes just like the shape of foam(Called three-dimensional connected channel) and myriad eyelets which only been found in big times microscope. Compare to similar ones, our products have many advantages as below: --Stable chemical composition --Excellent strength --Resistant to high temperature --Calm down of the turbulent flow of metal nicely --big m2/m3 --Superior dimensional tolerances: +0/-2.5 Suggestions: A. Control the melting point satisfactorily. Especially high temperature will destroy it's function. B. Suitable PPI for different casting materials. C. Use the maximum temperature as soon as possibly. D. The pouring highness don't exceed 20cm commonly, and metal liquid don't touch the filtration directly.Routine size:178x178x50 mm or 7'' x7''x2''(20--50ppi) 229x229x50 mm or 9'' x9'' x2''(20--50ppi) 305x305x50 mm or 12'' x12'' x2''(20--50ppi) 381x381x50 mm or 15'' x15'' x2''(20--50ppi) 432x432x50 mm or 17'' x17'' x2''(20--50ppi) 508x508x50 mm or 20'' x20'' x2''(20--50ppi) 584x584x50 mm or 23'' x23'' x2''(20--50ppi) Alumina Ceramic Foam Filter Data Sheet Model Material /Item Density (PPI) Porosity (%) Refractoriness () Bending Strength (Mpa) Compression Strength (Mpa) Thermal Shock Resistance (time/1100) KFF-2 Alumina 4-60 80-90 1150 0.6 0.8 ≥6
