ceramic rasching ring

Ceramic Raschig Ring Ceramic Raschig Ring has excellent acid resistance and heat resistance. It can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions. Consequently the application range is very wide. The packing can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers and actifier columns in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc. Chemical AnalysisAl2O3SiO2Fe2O3CaOMgOK2O + Na2OOther17-23%>70%<1.0%<1.%<0.5%<3.5%<1%Physical propertiesItemValueWater absorption<0.5%Apparent porosity (%)<1Specific gravity2.3-2.35Operation temp.(max)1000°CMoh's hardness>6.5 scaleAcid resistance>99.6%Alkali resistance>85%Dimension and other physical propertiesSizes (mm)Thickness (mm)Surface area (m2/m3)Free volume (%)Number per m3Bulk density (kg/m3)Packing factor ( m-1)6 × 61.6712623022935961524912.5 ×12.52.436764377867881190316×16230573192 50073090019×192.42437210912280183725×253.2190744767567350838×384.8121731366768931240×404.51267512700057735050×504.593816 00045722050×506.49274579265721380×809.546801910714280100×1001070701000700
