Ceramic rasching ring best thermal shock acid and heat resistance alumina zirconia ceramic ring
Ceramic rasching ring is the oldest type if chemical packing as a mass transfer media, with simple shape and the outside diameter is equal to the height. Ceramic raschig ring has excellent acid resistance and heat resistance. Ceramic rasching ring 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.
Application:
Ceramic rasching ring 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.
