N2-Nitrogen

Product name:Industrial Nitrogen, Pure Nitrogen, High Purity Nitrogen, Ultra-Pure Nitrogen, N2    

Relative molecular mass: 28.0134 (calculated according to the 2005 international relative atomic mass)    

Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.    

Nitrogen Application

Nitrogen Application
1.Due to the chemical inertness of nitrogen, it is often used as a protective gas, such as: fruits, food, and light bulb filling gas.
2.To prevent certain objects from being oxidized by oxygen when exposed to air, filling granaries with nitrogen can prevent grain from rotting and sprouting, and preserve it for a long time.
3.Liquid nitrogen can also be used as a deep freezer. As a cryogen, it is often used in hospitals to remove spots, acnes, etc., that is, to freeze off spots, acnes, etc.
4.High-purity nitrogen is used as a carrier gas for instruments such as chromatographs.
5.Used as a protective gas for bright annealing of copper tubes.
6.Used together with high-purity helium and high-purity carbon dioxide as laser gas for laser cutting machines.
7.Nitrogen is also used as a protective gas for food preservation.
8.In the chemical industry, nitrogen is mainly used as a protective gas, replacement gas, washing gas, and safety gas.
9.Used as a protective gas for aluminum products, aluminum profile processing, aluminum thin rolling, etc.
10.Used as a protective gas for reflow soldering and wave soldering to improve welding quality.
11.Used as a protective gas in the production process of float glass to prevent tin bath oxidation.
