Liquid oxygen
Product Description :
Product description
Chemical formula:O2
Molecular weight:32
Properties and use: Products using cryogenic air separation method obtained, the density 1140kg/m3, boiling point -183 ¡æ, the liquid was blue.
Commonly used in metal welding and cutting, Purification98.5 ~ 99.2% of the combination of oxygen and combustible gas, get a high flame temperature, make the metal melt.
In ferrous metallurgy, the oxygen is widely used in steel smelting and rolling. In non-ferrous metallurgy, and more use of oxygen-rich air. Oxygen and used to enhance the production of nitric acid and sulfuric acid. Medical oxygen therapy for treatment of pneumonia, gas poisoning and anoxia.
