1. Introduction:
Ceramic Rasching Ring is a traditional packing, with simple shape and the outside diameter is equal to the height.
It has excellent acid resistance and heat resistance, resisting to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid.
2. Application Area:
In high or low temperature condition, 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.
