Random Packings Of Ceramic
The ceramic random packings have 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 dry towers, absorbing towers, cooling towers, scrubbing towers and actifier towers in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc.
