Product description

Parameters

　　Gao Chunyang:

　　Product Name: high purity oxygen high, purity, oxygen

　　Molecular formula: O2

　　The purity of the product is not less than 99.995%

　　Properties: oxygen is the most common combustion supporting gas, and almost all of the oxidation and combustion processes require oxygen. Oxygen is one of the components of air, colorless, odorless, tasteless. Oxygen density than air, in the standard situation (0 degrees Celsius and atmospheric pressure 101325 PA), the density is 1.429 grams / liter, at the pressure of 101kPa, oxygen at about -180 degrees Celsius into a light blue liquid. Industrial production method of oxygen is the fractional distillation of liquid air, the compressed air, the oxygen after freezing for bentonite swelling liquid air, because the boiling point of rare gases and nitrogen than low oxygen, after fractionation, remaining is oxygen. Small amounts of oxygen can be stored in high-pressure cylinders and stored at 13.5MPa pressure. Large quantities of oxygen can be stored in liquid oxygen, liquid oxygen tank Dewar in transportation.

　　Use: oxygen with acetylene to produce oxyacetylene flame used for cutting metal

　　Medical oxygen is used for breathing gases in hospital patients, firefighters and divers

　　Oxygen is used in the glass industry

　　High purity oxygen is used in the electronics industry

　　High purity oxygen is used for special instruments
