Nitrogen, due to its chemical inertness and physical properties, plays a significant role in various fields such as industrial manufacturing, food preservation, electronic technology, and environmental protection.
Industrial Manufacturing
In metal processing, it serves as a protective gas and is used in the processes of bright quenching and annealing to reduce high-temperature oxidation reactions;
It is a key raw material in chemical production, used in the synthesis of ammonia, fertilizers, and nitric acid, etc.
It is used in the petroleum industry for pipeline cleaning, oil well pressurization and tank inerting.
Food preservation.
By using nitrogen-filled packaging, the microbial activity is inhibited, thereby extending the shelf life of foods such as fruits, vegetables, and meats.
Antioxidant protection measures in the production of alcoholic beverages and edible oils.
Electronic technology.
Inert gas protection for chip packaging and lithography processes in semiconductor manufacturing;
Preventing electrode materials from oxidizing during lithium battery production.
Environmental protection and healthcare.
In wastewater treatment, it serves as a purge gas to reduce the volatilization of harmful substances;
