Carbon dioxide in gaseous and liquid cylinders
The carbon dioxide in gaseous and liquid in cylinders represents gaseous fluid of carbon dioxide (carbon dioxide), derived from ammonia production of waste gases and combusting the fuel based on other manufactures (produced low-temperature liquid, the liquid and the gaseous high pressure).
The carbon dioxide in gaseous and liquid in cylinders is used to create protective environment during welding cylinders, and in producing carbonated beverages.
It is also widely used for food storage, and it has twice the highest refrigeration capacity.
GOST 8050-85
Code: CN FEA 2811210000
Chemical formula - CO2
Application area:
Carbon dioxide is used for various purposes:
• As a protective environment at welding with wire
• As a source of energy for the engine in aeromodelling
• As disintegrant
• For cooling, freezing and storing food.
• Widely used in the manufacture of fire extinguishers.
• Used as a preservative and is indicated on the packaging under the code E290.
• It is used for drying foundry molds
Safety precautions: Carbon dioxide is an inert gas without color and smell, heavier than air by 1.5 times. The liquid carbon dioxide – a colorless, odorless liquid. Carbon dioxide is non-toxic; non-explosive. The degree of impact on the human body belongs to the 4th class of hazard.
