LIQUID CARBON DIOXIDE
DSTU 4817:2007
Chemical formula CO2
MaiN properties and field of usage
Carbon dioxide is odourless colourless liquid; it is non-toxic and non-explosive.
It is used for creation of shielding medium during metals' welding, in food industry for aerated drink' manufacturing; for cooling, freezing and storage of the foodstuffs; for the casting moulds' drying; for the fire-extinguishing needs.
