Ceramic rasching ring

Ceramic rasching ringhas excellent acid and heat resistance. It can standup to corrosion of various inorganic acids, organic acids and organic solvents except HF. It can be used in high or low temperature. Application ranges wide. It can be used in drying, absorbing,cooling and regenerating tower in chemical, metallurgic, coal gas and air separation industry, etc. Typical chemical composition SiO2 68-72 MgO 0.6 Al2O3 18-22 CaO 0.6 Fe2O3 Max. 1 K2O 3.5-4.5 Na2O 0.1-0.3 Soluble Fe: <0.01% Acid resistance: 99.5%(DIN51102 sheet 2) Typical physical properties Density g/cm³ 2.3-2.4 Water Absorption % 0-0.5 Compressive Strength N /mm² 300-500 E-Modulus GPa 60 Mohs Hardness Scale 7-8 Specific heat, 20-100 J/kgK 840-920 Thermal Conductivity 30-100 W/mK 1-1.5 Coefficient of thermal expension (20-600)10-6K-1 4.7 Heat Resistance Up to 1000 Specific properties of Ceramic Rasching Rings Size Packing density(kg/m³)Spec.surface(m²/m³)Void space(%)Numbers per m³Ø3.53.5*3.5*0.811008907318650000Ø66*6*0.81050790733110000Ø88*8*1890710701562500Ø1010*10*1.285046070800000Ø1212*12*1.481039071579000Ø1515*15*1.578035070195000Ø1616*16*273030573192500Ø2525*25*2.56162357839000Ø3838*38*3.55721957614600Ø4040*40*55771887512700Ø5050*50*5528150815280Ø8080*80*9.5870110681950Ø100100*100*1080095701000Ø120120*120*126708560580Ø150150*150*158306850296
