Seven, nitrogen application
Due to the chemical inertness of nitrogen, it is often used as a protective gas, such as: fruits, foods, bulbs filled with gas.
In order to prevent some objects from being oxidized by oxygen when exposed to air, filling the granary with nitrogen can make the grain not mold, germination and long-term preservation.
Liquid nitrogen can also be used as a deep cryogen. As a cryogen, it is often used in hospitals to remove plaques, bags, beans, etc., and freeze the spots, bags, beans, etc.
High-purity nitrogen is used as a carrier gas for instruments such as chromatographs.
Used as a bright annealing protective gas for copper tubes.
Used as a laser gas for laser cutting machines with high-purity helium and high-purity carbon dioxide.
Nitrogen is also used as a food preservation gas.
In the chemical industry, nitrogen is mainly used as a protective gas, a replacement gas, a scrubbing gas, and a safety gas.
It is used as a protective gas for aluminum products, aluminum profile processing, and aluminum thin rolling.
Used as a shielding gas for reflow soldering and wave soldering to improve soldering quality.
Used as a shielding gas in the production process of float glass, anti-tin bath oxidation.
